How is RFID technology used in ports?Vehicle management in traditional port terminals is mainly achieved through information management systems combined with manual control and non-real-time data entry. Its management and scheduling methods have problems such as low efficiency, high labor costs, high error rates, and poor real-time performance.Smart ports are based on modern infrastructure equipment, with the core of deep integration of new generation information technologies such as cloud computing, big data, Internet of Things, mobile Internet, and intelligent control with port transportation business, and driven by innovation in port transportation organization services. With the guarantee of complete systems, mechanisms, laws and regulations, the optimal allocation of port resources can be achieved at a higher level. A new modern port transportation format that meets the requirements of multi-level, agile, and high-quality port transportation services and has distinctive features such as production intelligence, management wisdom, service flexibility, and strong support.Driven by emerging technologies such as autonomous driving, artificial intelligence, blockchain, and 5G, innovative applications such as automated terminals and smart factories are emerging one after another. Ports are gradually transforming and upgrading towards automation and intelligence, which also puts forward higher requirements for port vehicle management.In the loading and unloading process of various bulk cargo terminals, RFID technology has effectively improved and improved the port's vehicle automation management level. It speeds up the circulation of goods transportation, shortens the circulation cycle, and reduces management costs. Through the Internet of Things, RFID technology, artificial intelligence, 5G, big data and other technologies, we have achieved extensive connectivity and comprehensive awareness of terminal equipment and full-process operations. While improving efficiency and controlling costs, it also ensures safety, protects the environment, and promotes the sustainable green development of the port.At the port terminal, the traffic flow is very large. We use the vehicle dispatching system to ensure that vehicles can handle business in an orderly manner. By planning the vehicle operation route in advance and automatically guiding the vehicle to the specified node through queuing and calling, the pickup, unloading, material inspection and other services can be completed in an orderly manner. This has greatly shortened the waiting time for drivers, effectively controlled the number of vehicles arriving at the port terminal, eliminated random parking of vehicles, alleviated on-site traffic pressure, and improved vehicle traffic efficiency.Based on RFID technology, we promote the informatization and automation of port vehicle management and create a "safe, environmentally friendly, and efficient" smart port, which can effectively improve port operation efficiency and management levels. Through RFID technology, video surveillance and other technologies, the location, driving speed, path and dynamics of vehicles entering the port are collected. Mainly through RFID tags, each truck entering and leaving the port is bound, and the basic information of the vehicle, customs declaration information, cargo information and other business details are recorded in detail. Through the comprehensive arrangement of RFID readers, RFID antennas and other equipment, data on trucks entering and leaving the port can be automatically collected in real time. The relevant vehicle information is displayed in real time on the monitoring screen, and the vehicle's running trajectory and regional location information are grasped in real time. It also sends early warning information to operators in a timely manner to improve port operation efficiency and ensure the safety of goods at port terminals.Generally speaking, the purpose of building smart ports is to realize the transformation and upgrading of traditional ports. However, the operational goals of smart ports and traditional ports are the same, but the means of implementation are richer and the technology content is higher. Smart ports can not only improve production efficiency and significantly reduce production costs, but also achieve the goal of green and low-carbon development. Therefore, building smart ports is of great significance to achieving green and sustainable development of ports.

How is RFID used in the pharmaceutical industry?1. Introduction to RFID technologyRFID radio frequency identification is a non-contact automatic identification technology. It is a technology that uses radio frequency signals to achieve contactless information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieves identification purposes through the transmitted information. It began to rise in the 1990s and gradually matured. It consists of three parts: tag reader and antenna.(1) TagAlso known as electronic tags or smart tags, it is a chip with an antenna in the memory. The chip stores information that can identify the target. Composed of coupling components and chips, each tag has a unique electronic code and is attached to the object to identify the target object.(2) ReaderA device that reads (and sometimes writes) tag information. Readers and writers are divided into handheld and fixed types.(3) AntennaPasses radio frequency signals between tags and readers2. Application of RFID in the medical industryIn the medical system, the function of identity recognition is the first, followed by sample identification, and the third is to improve the efficiency of data entry. The purpose of hospital informatization is to provide correct treatment to patients at the right time, at the right place, and to accurately record the treatment environment. Globally, the magnitude of medical errors is significant. According to statistics: The number of deaths caused by medical errors in the United States every year is approximately 48,000 to 960,000. The number of deaths caused by medical errors ranks fifth in the United States, and the probability of similar medical errors in our country is even higher. . This risk is mainly due to insufficient knowledge and information, as well as identification errors. Scientific and reasonable hospital information systems can greatly reduce this kind of medical errors. So based on the current level of hospital informatization and prospects for the future, what are the applications of RFID technology?(1) Application on hospital staff badgesCurrent situation: In HIS systems and other application systems, the account number and password need to be remembered by staff, and the input when logging into the system is cumbersome and the security factor is low.After application: Personnel do not need to enter an account number to log in to the system, just scan the card, and can also set a password, which is convenient and fast. And because system login requires a unique personnel ID card and password, it is safer to use.(2) Use of wristbands for inpatientsCurrent situation: The workload of medical staff in medical institutions is detailed and diverse, and requires a lot of patience and meticulousness to not make the slightest mistake. Mainly reflected in: the inability to quickly understand the drugs that patients are taking during ward rounds. It is time-consuming and labor-intensive for nurses to check the daily distribution of medicines, and it is possible that the wrong medicines are taken or the wrong injections are given. In the event of an emergency, basic information such as the patient's past medical history and allergy history cannot be obtained immediately; the patient's basic vital characteristics are also recorded by adding paper manually. There is no nurse work statistics and clear work responsibilities.After application: Through the unique uniqueness of RFID tags, patient information can be quickly and accurately identified, and the latest medical order information can be quickly extracted, thus saving valuable rescue time and avoiding medical accidents due to negligence. And can record every detail of daily nursing work in a timely and accurate manner. Achieve traceability management, reduce the daily workload of medical staff, and improve work efficiency. Free medical staff from their daily heavy workload, so that they can provide better and more in-depth services to patients.(3) Disinfection tracking of instrument packages supplied to the sterilization centerCurrent situation: The current disinfection supply center provides the supply of sterile items throughout the hospital. The staff's work intensity is high, the work is disordered, and the level of informatization is low. It is difficult for the hospital's senior management to manage the work process, and it is impossible to effectively monitor the disinfection process of surgical kits and to trace the quality. Due to personnel negligence, secondary pollution caused by the use of paper to exchange information, and frequent medical accidents, waste occurs repeatedly.After application: Through the application of RFID technology, the collection, transmission, storage and use management of business data in the supply room have been strengthened. It promotes information sharing so that medical staff, decision-makers, and managers can obtain the information they need in a timely and accurate manner. Improve work quality and solve the problem of lack of visualization and information-based traceability management of the surgical package process in the supply room, so as to trace single packages of instruments. Through the personnel management of the surgical bag disinfection process, the hospital can accurately assess employees on a piece basis. Avoid hidden dangers caused by cross-infection or incomplete disinfection during the surgical package process(4) Current status of tracking medical wasteAt present, most medical and health institutions lack effective and full supervision of all aspects of waste disposal, resulting in confusion in the classification of medical waste, or unreasonable classification and collection, and those that are treated separately are not treated separately, and those that need to be incinerated are not incinerated. As a result, it is not uncommon for medical waste to be mixed into domestic waste, and a small amount of medical waste is illegally processed for secondary processing or used as raw materials for other daily necessities; and new secondary pollution occurs during the transportation of medical waste.After application: Combined with the medical waste management system and the hospital's real-time targeting system, each epidemic prevention and administrative unit can instantly and accurately grasp the dynamic information of the entire treatment process, thereby preventing the recurrence of nosocomial infection control problems similar to the SARS epidemic. Standardize all aspects of the medical waste disposal process to avoid medical accidents caused by the outflow of medical waste for reuse; use scanning equipment to collect information throughout the process to avoid secondary cross-infection. By swiping cards to log in by personnel in each link of waste disposal, their respective responsibilities are clarified, and traceability management can be quickly and accurately carried out in the event of medical waste loss or accidents.(5) Application in drug managementCurrent situation: At present, in the pharmaceutical industry, due to the large number of pharmaceutical wholesale companies but small ones, it is difficult to guarantee the quality of pharmaceuticals during storage and transportation. Moreover, drugs lack unified standard coding, and the logistics information system is seriously lagging behind, seriously affecting drug quality supervision and the use of drugs on patients. There is no full-process tracking mechanism in the entire drug circulation link, and there is a lack of traceability management.After application: Identify physical objects at any stage of the pharmaceutical process from manufacturing to distribution and use to achieve full traceability management. Reduce errors in drug production, distribution, prescription, and medication taking in the medical field, and prevent patients from being given the wrong medicine, or certain expired or counterfeit medicines.(6) Application in triageCurrent situation: Currently, various outpatient triage systems do not solve the problem of empty calls, but they cannot limit patients to a circle, which leads to the phenomenon of empty calls when doctors call numbers.After application: Through the positioning function of RFID, it can help the system to automatically capture the patient's specific location and notify the system of the patient's status in real time, thus solving the problem of empty calls in the calling system.(7) Application in infusionCurrent situation: Outpatient infusion is an important part of current medical activities. The workload is heavy and the business is busy and trivial. However, once an error occurs, the safety of the patient may be endangered. At the same time, due to the need to receive a large number of patients and their families every day, the outpatient infusion room of the hospital has become a place where people are concentrated and mobile, which brings many difficulties to nursing management. At present, a large number of medical institutions have not implemented digital management, and a few medical institutions have achieved digitalization, but this still does not solve the problem of manual verification when checking patient information during infusion, which inevitably leads to the problem of medical errors.After application: The unique identification of RFID is used to match personnel and drugs during the infusion process, which reduces medical errors by medical staff; reduces the work pressure of medical staff and improves work efficiency.3. RFID application prospectsAt present, the informatization direction of hospitals is developing in a patient-centered direction, which requires us to strengthen the quality of our medical services on the basis of improving the quality of medical care, and we can solve this problem for us with the help of information means such as RFID. This question. This solves the current problem of lack of visualization, informationization, and traceability management of the entire patient medical treatment process in hospitals. Moreover, the hospital's informatization construction is very scattered. Although most business data are related, traceability is not strong due to differences in structure and storage between systems, making it impossible to make management more standardized, and the process is not highlighted enough. In the medical industry, through the use of RFID technology, especially in the mobile tracking of patients using RFID technology, the patient's actions and status during treatment can be understood in real time, so that patients feel a sense of security, and the hospital can truly achieve patient-centered mobilization. Only with medical resources can the core values ​​of hospital management be effectively realized.With the development and introduction of RFID technology and the reduction of costs, its application in various industries will become more and more in-depth and widespread, and the application of RFID technology has gradually entered a mature application period. It is foreseeable that RFID technology will have a bright future in the medical information industry.

As the Internet of Things gradually enters our lives, more and more people are understanding what Internet of Things technology is. Today we will start from RFID technology and let everyone know which layer of the Internet of Things RFID technology belongs to.Which layer of the Internet of Things does rfid technology belong to?The IoT technology system can be divided into four layers: perception layer, network layer, platform layer and application layer. Each layer has different responsibilities. The perception layer is the tentacle of the Internet of Things, which helps the Internet of Things collect data. RFID technology belongs to the perception layer of the Internet of Things. The network layer mainly transmits information; the platform layer provides an interactive platform for various devices to achieve remote control; the application layer mainly processes data collected from the device to provide intelligent services to different industries.1. Perception layerThe main function of the perception layer is to collect data from the physical world, which is the key bridge for communication between the human world and the physical world. There are two main sources of data for the perception layer:One is to actively collect and generate information, such as sensors, multimedia information collection, GPS, etc. This method requires active recording or interaction with target objects to obtain data. There is a process of collecting data, and the information is highly real-time.The other is to passively save information by accepting external instructions, such as radio frequency identification (RFID), IC card identification technology, bar code, QR code technology, etc. This method generally saves the information in advance and waits to be read directly.For example, the access control cards used in some communities now use RFID identification technology. The user information is first entered into the central processing system, and then the user simply swipes the card every time he enters the door.2. Network layerThe main function of the network layer is to transmit information and transmit the data obtained by the perception layer to the designated destination.In the field of Internet of Things, embedded programs are equivalent to the human brain. After the information collection is completed, the brain will issue instructions to the communication module to transmit the information to a certain node. The network layer will involve what kind of communication network to choose and what kind of communication mechanism to use to transmit the information.The word "net" in the Internet of Things actually contains two parts: access network and Internet. Access to the network can connect things with the Internet and realize information interaction between people and things, and things and things. At present, there are mainly two types of access networks, one is wired network access, and the other is wireless network access.Wired mainly includes Ethernet, serial communication (RS-232, RS485, etc.) and USB, etc.Wireless is divided into short-range wireless, short-range wireless and long-range wireless communications. Short-range wireless communication mainly includes NFC, RFID, IC, etc. Short-range wireless communication mainly includes Wifi, ZigBee, Bluetooth, etc. Long-distance wireless communication mainly includes GSM (2G, 3G, 4G, 5G, etc.), eMTS, Lora, NB- IoT etc.3. Platform layerThe IoT platform can provide devices with safe and reliable connection and communication capabilities, connect downwards to a large number of devices, support data reporting to the cloud, and provide cloud API upwards. The server sends instructions to the device by calling the cloud API to achieve remote control.The IoT platform mainly includes device access, device management, security management, message communication, monitoring operation and maintenance, and data applications.Device access mainly refers to how the device connects and communicates with the IoT platform, which is mainly reflected in:Device-side development: Provide device-side SDK development for MQTT, CoAP, HTTP, HTTPS and other protocols to help different devices easily accessDevice network access management: Provides different network access solutions based on cellular (2G, 3G, 4G, 5G), NB-IoT, LoRaWAN, WI-FI, etc.4. Application layerThe application layer is the ultimate goal of the Internet of Things. It mainly processes the data collected from the device to provide intelligent services to different industries.Currently, the Internet of Things involves many industries, such as electricity, logistics, environmental protection, agriculture, industry, urban management, home life, etc., but essentially there are four main types of Internet of Things services:Monitoring type, such as logistics monitoring, pollution monitoring, etc. Control type, such as intelligent transportation, smart home, etc. Scanning type, such as mobile wallet, highway non-stop toll collection, etc. Inquiry type, such as remote meter reading, intelligent retrieval, etc.IoT business processing is relatively complex because it involves the integration of massive data, which poses a great challenge to end users in different industries. Therefore, there are currently specially provided middleware on the market such as cloud computing, data mining, artificial intelligence, information fusion, etc. that can be used by industry players. This has also stimulated the prosperity of the Internet of Things application industry to a certain extent.The above is the relevant content about which layer of the Internet of Things RFID technology belongs to. There are many technologies involved in the Internet of Things. It includes not only RFID radio frequency identification technology, but also sensors, multimedia information collection and other technologies. Faced with many key technologies, we can choose the appropriate sensing method based on our own actual conditions and application scenarios!

Compared with barcode technology that collects one by one, RFID technology can perform non-contact, long-distance, and batch identification of RFID tags.RFID handheld terminal is a handheld terminal device with RFID reading function. In addition to reading RFID tags, the RFID handheld terminal also integrates other data collection methods and functions to meet the application needs of different scenarios.1. RFID reading and writing: Due to the different frequencies of RFID tags, RFID handheld terminals are also divided into LH (low frequency), HF (high frequency), and UHF (ultra high frequency).2. Barcode scanning: The RFID handheld terminal can be equipped with an optional laser scanning engine to scan 1D/2D barcodes.3.

Working temperature: Industrial design, can be used in high and low temperature environments.

How is RFID used in the logistics field?Application of RFID in logistics fieldJob task requirements: Understand the concepts and principles of RFID technology, analyze the advantages and disadvantages of RFID technology, understand the types of RFID, and be familiar with common applications of RFID.Radio frequency identification technology (RFID) is a non-contact automatic identification technology that entered the practical stage in the mid-20th century. The radio frequency identification system consists of radio frequency tags and readers. Radio frequency tags are carriers that carry identification information, and readers are devices that obtain information. Radio frequency identification tags and readers use induction, radio waves or microwaves to conduct two-way communication to realize the identification and data exchange of information stored in the tags.1. Principle of RFIDThe RFID technology system consists of three parts: electronic tag, reader, antenna and host system. The electronic label is equivalent to the barcode in current barcode technology, which stores the unique identification code of the goods, including key supply information such as origin and date. Different from barcodes, labels can store a large amount of information and can send cargo information in the form of wireless signals automatically or under the action of external forces. The sending distance is related to the type of electronic tag, ranging from tens of centimeters to tens of meters, achieving non-contact operation. The reader is a wireless signal receiving device, and its complexity varies greatly depending on the electronic tag. After the reader receives the information sent by the tag, it translates and verifies it. After determining that it is correct, it instructs the transmitter to stop working, so that multiple tags can be read in a short time and in a small space, and cargo information can be obtained in batches. The transmission and reception of data transmitted between the electronic tag and the reader is completed by the antenna, and the host system is responsible for processing these data movements.The basic principle of RFID technology is electromagnetic theory. The advantage of the radio frequency system is that it is not limited to line of sight, and the recognition distance is farther than that of the optical system. Radio frequency identification tags have the ability to be read and written without contact, can carry a large amount of data, are difficult to forge, and are intelligent.Radio frequency identification technology is a non-contact automatic identification technology. The antenna emits radio waves to form a magnetic field. After the electronic tag enters the magnetic field, the coil inside it can induce the magnetic field and generate current. Under the energy supply of current, the stored product information is converted into radio frequency signals and sent to the reader. After the reader reads and decodes the information, it is sent to the host system through the antenna for relevant data processing.The tag in RFID is a combination of RFID tag chip and tag antenna. When used as shown in the figure, special information is first encoded into the electronic tag, and then the tag is affixed to the items that need to be identified or tracked.Some RFID systems are read-only, others allow adding or changing existing information in the tag. All RFID systems feature contactless reading capabilities at reading distances from 2.54 cm to 254 cm or greater. Since harsh environments may cause damage or malfunction to contact or near-contact readers, the application of non-contact readers will be very wide, especially some radio frequency identification systems already have a memory of up to 1M , which brings great convenience to data processing.Knowledge link: Factors affecting radio frequency identification systemsThe radio frequency identification system is non-contact reading and writing, and its wireless transmission distance is determined by many factors, such as transmission frequency antenna design. For the specific situation of applying radio frequency identification technology, the transmission distance, operating frequency, data capacity, size, weight, positioning, response speed and selection ability of the tag should be considered.2. Characteristics of RFID(1) Radio frequency identification tags are resistant to harsh environments, waterproof, antimagnetic, high temperature resistant, have a long service life, and are more flexible in placement than barcode tags. And it requires almost no maintenance. Dust, paint and other opaque substances will not affect the readability of RF tags.(2) RFID tags are non-contact reading and do not need to be read like barcode tags. The information will not be washed away by strong magnetic fields. Information can be read accurately as long as it is placed within the electromagnetic field formed by the reading device, with an extremely low error rate. . Therefore, it is more suitable for use with various automated processing equipment, while reducing or even eliminating the waste of human resources, reduced efficiency, errors and error correction costs caused by manual intervention in data collection.(3) RFID can perform thousands of reads per second and can process many tags at the same time. It is efficient and highly accurate, allowing companies to operate without reducing (or even improving) efficiency. Without increasing (or even reducing) management costs, it can greatly improve the precision of management, make the entire operation process transparent in real time, and create huge economic benefits.(4) The data on the RFID tag can be modified repeatedly, which can not only be used to transmit some key data, but also enable the RFID tag to be recycled and reused within the enterprise. Convert one-time costs into long-term amortized costs, further saving enterprise operating costs while reducing the risk costs of enterprises adopting RFID technology(5) The reading of RFID tags does not require visual visibility because it does not rely on visible light, so it can be used in harsh environments that barcode technology cannot adapt to. Such as high dust pollution, outdoors, etc., which can further expand the application scope of radio frequency identification technology.(6) The radio frequency identification system can also identify fast-moving items. Items with radio frequency tags do not need to be stationary during the reading process.(7) RFID tags have strong confidentiality and high security. RFID chips are very difficult to counterfeit. Hackers would need a deep understanding of wireless engineering, coding algorithms, and decryption techniques to crack it. In addition, hierarchical confidentiality measures can be implemented on the data on the label, so that the data can be read at certain points in the supply chain but not at other points. Some RFID standards also specify additional security measures.Radio frequency identification technology is applicable to a wide range of fields, such as material tracking, vehicle and shelf identification, transportation identification, road and bridge toll collection, security access control, tracking, automatic guidance of cars, automatic storage, tool identification, personnel monitoring, parcels and baggage classification, vehicle monitoring, etc.3. Types of RFID tagsThere are many types of RFID tags. Implantable tags are as small as a grain of rice, while larger tags used for long-distance communications (and even global positioning systems) are as big as a handheld telephone.Tags are divided into active tags and passive tags according to their working modes. The active tag itself carries a battery to provide it with the energy required for reader communication; the passive tag uses inductive coupling or backscattering working mode, that is, it obtains energy from the electromagnetic field or electromagnetic wave emitted by the reader through the tag antenna to activate the chip and adjust The matching degree between the radio frequency identification tag chip and the tag antenna feeds back the information stored in the tag chip to the reader.Electronic tags can be divided into low-frequency electronic tags, high-frequency electronic tags, ultra-high frequency electronic tags and microwave electronic tags according to different frequencies.Electronic labels can be divided into credit card labels, linear labels, paper labels, glass tube labels, round labels and special-purpose special-shaped labels based on different packaging forms.4. Common applications of RFID technology in the logistics fieldAt present, radio frequency identification technology is widely used at home and abroad in visitor control, store anti-theft systems, item and inventory tracking, automatic charging, tracking, manufacturing process management, intermodal container and air cargo tracking, etc. It is especially widely used in modern logistics management and military logistics support. Combining RFID technology with portable data terminals (PDTs) allows the collected useful data to be stored or transmitted to a management information system. Connected to an appropriate scanner it can be effectively used in many automatic identification applications. Radio frequency identification technology is now widely used in the following fields.1. Automatic identification of vehicles(1)Realizing automatic identification of train numbers has been a long-standing dream of railway people. After the advent of RFID technology, it quickly attracted attention from the railway sector. Judging from foreign practice, the North American Railroad Association approved the automatic train number identification standard using RFID technology in early 1992. As of December 1995, 150,000 trains in North America had used it in three years. RFID devices were installed on trucks and 1,400 locations, successfully establishing an automatic vehicle number identification system in a large area for the first time. In addition, some European countries, such as Denmark and Sweden, have also established localized automatic vehicle number identification systems using RFID technology. Australia has also developed an automatic identification system in recent years for the identification and management of mining vehicles.(2)Highway Toll Collection and Intelligent Transport System (ITS)The automatic highway toll collection system is one of the most successful applications of RFID technology, which fully demonstrates the advantages of non-contact identification. The vehicle automatically completes toll payment while passing through the toll station at high speed, solving traffic bottlenecks and avoiding congestion. It also prevents problems such as embezzlement of tolls in cash settlement. American Amtch Company, Swedish Tagmaster Company, etc. have developed complete systems for highway toll collection.(3) Contactless identification cardMost foreign transactions are completed using various cards, which are so-called non-cash settlements, such as phone cards, membership fee cards, savings cards, subway and bus passes, etc. In the past, most of these cards were magnetic cards or IC cards. Since magnetic cards and IC cards use contact reading, they have poor resistance to mechanical wear and interference from external strong electricity and magnetic fields, and magnetic cards are easy to forge. At present, there is a strong trend of being replaced by contactless identification cards. According to information provided by Japan's AIM, Japanese companies operating magnetic card phones plan to invest 500 million yen to replace the original magnetic card phones within two years starting in 2017; Japanese companies operating subways and game consoles have also invested A large amount of money was spent to cancel the original magnetic card equipment and replace it with contactless identification cards.(4) Automation and process control of production linesRFID technology is used to realize automatic control of production lines, monitor quality, improve production methods, and increase productivity, such as in automobile assembly lines. Many famous foreign cars, such as Mercedes-Benz and BMW, can be customized according to user requirements, which means that every car that comes off the assembly line is different. The assembly processes determined by tens of thousands of internal and external options are diverse, and it is difficult to handle such a complex task without a highly coordinated and complex control system. The German BMW company is equipped with an RFID system on its car assembly line to ensure that the car completes the assembly tasks accurately at each position on the assembly line, as shown in Figure In industrial process control, many harsh and special environments have adopted RFID technology. Integrated circuit manufacturers such as MOTOROLA and SGSTHOMSON have adopted automatic identification process control systems incorporating RFID technology to meet the special requirements of semiconductor production for ultra-clean environments. Other automatic identification technologies, such as barcode technology, cannot work under such harsh chemical conditions and ultra-clean environments.(5) Cargo tracking and item monitoringThe transportation of many goods requires accurate knowledge of the location of the goods, such as dangerous goods, etc. RFID equipment installed along the line can track the entire process of transportation, and some are also combined with GPS systems to implement effective tracking of goods. RFID technology is used in stores to prevent the theft of certain valuable items, such as Electronic Article Surveillance Systems EASKnowledge Link: Portable Data Terminal (PDT)In recent years, there have been many applications of portable data terminals (PDTs), which can store or transmit useful data collected to a management information system. Portable data terminals generally include a scanner, a small but powerful computer with memory, a display and a keyboard for manual input. A resident memory operating system is installed in the read-only memory, which is used to control the collection and transmission of data. The data in the PDT memory can be transmitted to the host computer at any time through radio frequency communication technology. During operation, the location label is scanned first, and the shelf number and product quantity are entered into the PDT. This data is then wirelessly transmitted to the computer management system through RFID technology, and information such as customer product lists, invoices, shipping labels, product codes and quantities stored in the place can be obtained. 5. Application of RFID technology in e-commerceE-commerce uses Internet technology to connect enterprises and customers. The entire supply chain consists of enterprises, logistics centers and customers, reducing intermediate links. Compared with traditional commerce, the role of logistics centers has become more and more prominent. Logistics centers are both corporate warehouses and customers' supply warehouses. The efficiency of the logistics center directly determines the efficiency of the entire supply chain. The use of RFID technology can improve the management level of the logistics center and effectively improve the speed of the e-commerce supply chain.(1) Automatic warehousing operationAfter receiving the incoming goods list, the warehouse of the logistics center begins acceptance and sorting. Before the goods are put into storage, it is necessary to pre-write the name, specification, manufacturer and other relevant data in the RFID electronic tag, and install the prepared label on the surface of the goods, packaging boxes or pallets. At the same time, the host system allocates cargo space to the batch of goods and generates warehousing instructions. A reader and a tablet computer are installed on the vehicle, and the warehousing instructions are sent to the tablet computer through the antenna from the host system. When getting on the forklift to pick up the goods, the reader on the truck reads the label information and compares it with the warehousing instructions on the tablet to ensure the correctness of the operation. A reader is also installed at the entrance of the warehouse door. When the goods are put into the warehouse, the reader automatically reads the goods information in batches, counts and records the time of entry, and sends the information to the host system. After the forklift reaches the target cargo location, the reader reads the cargo location label, confirms that it is consistent with the instructed target cargo location, puts the goods on the shelf, and sends a confirmation message to the host system. The host system confirms the warehousing and updates the database, and compares the final warehousing result with the purchase list. After confirmation, the warehousing work is completed.Using wireless real-time transmission of RFID technology, various documents for warehousing operations are changed from manual entry to automatic reading. Realize paperless operations: Automatic verification through the host system reduces operational errors from the source and improves speed and accuracy. Of course, RFID tags can also be installed on each vehicle, and the host system can determine the location of the forklift at any time. When assigning warehousing tasks, select idle forklifts that are closer to the warehouse to increase the utilization rate of the forklifts. It can also record the workload of the forklift drivers and provide an objective basis for evaluating employee performance.(2) Quick inventoryE-commerce logistics centers have larger warehouse areas and a larger number of storage locations. A tally clerk tallies a large number of storage locations every day, and it is difficult to remember the storage status of goods in each location. The inventory takes a long time and has a high error rate. In addition, traditional inventory work requires scanning barcodes and checking multiple times. After the goods are shipped, the barcodes on the goods will wear out, causing difficulties in subsequent work. RFID can well solve the problem of inventoryWhen entering the warehouse, the goods have been loaded with RFID tags. The tallyman holds a mobile reader. When walking through the shelves, the reader reads the goods information and transmits it to the host system in real time, completing the inventory of the goods in a short time. . Through RFID non-contact work, the inventory speed can be accelerated. The inventory verification time is 1/20 of the traditional barcode recognition time. At the same time, the re-inspection process is reduced and the problem of barcode wear is solved. The handheld reader can identify goods within a certain distance. Even if the goods are placed scattered, it will not affect the efficiency of inventory. Especially when the goods are placed in a higher position, it avoids the trouble of staff climbing up to take inventory.(3) Efficient picking and outbound operations are highly efficientE-commerce logistics faces personalized and diversified demands. The order volume of goods is large and the disassembly rate is very high. You even have to select a book or a bottle of medicine. Picking work is a key link in the logistics center, and its efficiency directly affects the efficiency of the entire center. The reason for the warehouse explosion problem that has arisen in the past two years is that the picking efficiency is too low, and the pickers are unable to cope with the sudden increase in picking workload, resulting in a serious backlog of goods. The application of RFID technology can increase picking speed and accuracy and significantly improve logistics efficiency.When picking goods, the host system selects an idle forklift that is closer to the outbound area and sends outbound instructions to the forklift's tablet computer. After the forklift driver arrives at the target cargo location, the reader reads the cargo location label and cargo label, compares them with the outgoing instructions, and then takes away the goods after confirmation. The outbound door is also equipped with a reader. When all the goods are picked and pass through the warehouse door, the reader reads the cargo information, and the host system automatically enters the shipment quantity, product name, vehicle number and other information. Compare with the outbound order and change the data system if there is no error. If the quantity, variety, etc. do not match the outbound instructions, the host system will issue an alarm prompt command, usually with an LED light above the warehouse door. When the goods and other information are inconsistent with the outgoing instructions, this light will light up and a warning sound will sound to prompt the staff to review. The entire picking and shipping process is smooth and without pause, reducing the unboxing review and manual counting recording process of the traditional picking process, which is short in time and high in accuracy.

The history and current status of RFIDRFID is the abbreviation of Radio Frequency Identification (RFID) technology. It is a non-contact automatic identification technology developed based on radar technology. Compared with other automatic identification technologies, such as barcodes, optical identification and biometric identification technologies, it has the advantages of strong anti-interference ability, large amount of information, non-visual range reading and writing, and long life. It is widely used in fields such as logistics, supply chain, animal and vehicle identification, access control systems, library management, automatic toll collection and production and manufacturing.In 1948, Harry Stockman published the article "Communication using Reflected Power", which laid the theoretical foundation of RFID. Over the past half century, the development of RFID technology has gone through the following stages:From 1941 to 1950, RFID technology came into being with the improvement of radar. The application of radar in 1948 laid a theoretical foundation for RFID technology.From 1951 to 1960, RFID technology was still in its early exploration stage and was mainly conducted in laboratory research. Its related theories and technologies were not yet mature.From 1961 to 1970, the theory of RFID technology developed to a certain extent, and some application attempts began. For example, the first commercial example of RFID technology worldwide was the use of electronic anti-theft devices (EAS) to deal with thieves in shopping malls. This anti-theft device uses an electronic tag with only 1 bit of storage capacity to indicate whether the product has been sold. This electronic tag is not only cheap, but also can effectively prevent theft.From 1971 to 1980, RFID technology and product research and development were in a period of great development, and various RFID technologies and tests were accelerated. In terms of industrial automation and animal tracking, some of the earliest commercial applications and standards have emerged, such as industrial production automation, animal identification, and vehicle tracking.From 1981 to 1990, RFID technology and products entered the commercial application stage and began to be used on a large scale. However, different countries have different focuses on the application of radio frequency identification technology. The United States focuses on traffic management and personnel control, while Europe mainly focuses on animal identification and applications in industry and commerce.From 1991 to 2000, the number of manufacturers and applications using RFID technology increased day by day, and mutual compatibility and connectivity became the bottleneck that plagued the development of RFID technology. Therefore, the standardization issue of RFID technology has attracted increasing attention. It is hoped that through a globally unified RFID standard, radio frequency identification products will be more widely used and become an important part of people's lives.RFID technology products and applications entered a stage of rapid development after 1990. The American TI (Texas Instruments) began to become a pioneer in RFID and established the Texas Instruments Registration and Identification System (TIRIS). Currently known as TI-RFIS (Texas Instruments Radio Frequency Identification System), this is a major platform for RFID application development.In 1991, the world's first open highway electronic toll collection system was established in Oklahoma, USA. The vehicle's RFID electronic tag information is bound to the detection point location information and the car owner's bank card, and stored in a computer database. The car can pass through the toll detection point at high speed, and the fee can be automatically deducted from the car owner's bank card, and there is no need to set up lifting railings to block or cameras to capture the license plate.Lufthansa uses contactless radio frequency cards as air tickets, changing the traditional way of purchasing and selling air tickets and simplifying airport security procedures.In China, the city of Shanghai has installed an automatic road maintenance toll collection system based on RFID technology. Guangzhou and Foshan have applied RFID systems to open highways to automatically charge high-speed vehicles to improve vehicle passing efficiency and alleviate highway bottlenecks.In the mid-1990s, the Automatic Railway Identification System (ATIS) built by the Ministry of Railways of China used RFID technology to realize [automatic copying of train numbers for trucks]. Ground identification equipment (AEI) is installed at all section stations, marshalling stations, large freight stations and boundary stations to accurately identify running trains and vehicle information. On this basis, a computer automatic report collection system was established to store information such as railway train numbers, locomotive and freight car numbers, identification, attributes and locations. Real-time and autonomous statistics of railway vehicle management systems have been realized, becoming one of the most typical applications of RFID technology. Especially since high-speed railway trains began to operate, it is particularly necessary to use RFID technology for automatic, fast, and efficient management to reduce the probability of train accidents.In 1999, the Auto-ID Center of the Massachusetts Institute of Technology formally proposed the concept of Electronic Product Code (EPC). The combination of the concept of EPC, RFID technology and Internet technology will build a ubiquitous Internet of Things. Especially in recent years, IBM has proposed the concept of smart earth. After being affirmed by President Obama, the concept attracted widespread attention around the world.After 2001, the variety of RFID products has become more abundant, and standardization issues have attracted more and more attention. The application scale of the industry continues to expand, active tags, passive tags and semi-passive tags have all been developed, and the cost of tags continues to decrease. Wal-Mart, the world's number one retailer, announced the widespread use of RFID and the U.S. military announced that all military supplies would be identified and tracked using RFID, which greatly promoted the research and application of RFID technology and enriched and improved the theory of RFID technology.Since the beginning of the 21st century, with the continuous reduction of the cost of RFID tags and reading equipment, RFID technology has been more widely used, and some people even call it the terminator of bar codes. RFID technology is also used in medical care, electronic ticketing, access control management, etc. Several large retailers and some government agencies have mandated that their suppliers must have RFID tags on boxes and pallets of products shipped from distribution centers.In August 2009, former Premier Wen Jiabao proposed the concept of Perceiving China when he visited the Wuxi Internet of Things Industry Research Institute to inspect the construction of the Internet of Things. RFID technology will definitely form the front-end data collection platform of the Internet of Things together with the sensor network, and is the main component of the Internet of Things technology. Many people in the industry define 2010 as the first year of the Internet of Things.With the increasing informatization of society and the continuous advancement of science and technology, people have higher and higher requirements for work efficiency and automation. RFID technology combined with Internet, communication and computer technology can realize the tracking and information sharing of items on a global scale. Applying it to industries such as logistics, manufacturing and public information services can greatly improve management and operational efficiency and reduce costs. With the continuous improvement, development and maturity of related technologies, the RFID industry will become an emerging high-tech industry group and a new highlight of national economic growth.Current RFID research mainly focuses on technical standards, tag costs, key technologies and system applications.(1)Technical standards. In order to standardize the development, design and mass production of tags and readers and solve the interconnection and compatibility issues of RFID systems, RFID technology must be standardized. The standardization of RFID is an important issue that needs to be solved urgently. Countries and relevant international organizations are actively promoting the formulation of RFID technical standards. At present, there are no complete international and domestic standards for RFID. The standardization of RFID includes identification encoding specifications, operating protocols, and application system interface specifications. The identification encoding specifications include identification length, encoding method, etc.; the operation protocol includes air interface, command set, operation process and other specifications. The current main RFID technical standards include the European and American EPC standard, the Japanese UID (Ubiquitous ID) standard and the ISO 18000 series of standards.(2) Label cost. Tag cost is the key to limiting the success of commercial applications of RFID technology. RFID tags are mainly composed of IC chips, antennas and packages. According to the survey, the average price of passive HF band tags in 2003 was 91 cents, and the average price of UHF band tags was 57 cents. Some people predict that in the case of mass production, the production cost of RFID tags can be reduced to as low as 5 cents. By then, RFID technology will enter all areas of people's lives and provide people with cheaper, more efficient and more convenient services.(3) Key technologies. Research on key RFID technologies mainly focuses on frequency selection, antenna technology, low-power technology, packaging technology, positioning and tracking, anti-collision and safety technology, etc.Frequency selection: A key issue in RFID technology is the selection of operating frequency. The selection of operating frequency needs to be suitable for different applications and take into account the relevant regulations on the use of radio frequency bands and transmission power in various countries. The current working frequency of RFID spans multiple frequency bands, and different frequency bands have their own advantages and disadvantages. It affects not only the performance and size of the tag, but also the price of the tag and reader. In addition, differences in radio transmission power will also affect the range of the reader. To expand wireless coverage, the size of the tag antenna must be expanded. Low-frequency bands have relatively low energy, low data transmission rates, and limited signal coverage. However, the production cost of low-frequency tags is relatively low and comes in various shapes, making it easy to attach to the objects being identified and tracked. The high-frequency band has relatively high energy and is suitable for long-distance applications. At the same time, the data transmission rate in the high-frequency band is relatively high and the communication quality is good. Its disadvantage is that it is easily blocked by obstacles, easily affected by factors such as reflection and human body disturbance, and it is difficult to achieve full area coverage of the signal. Since the power loss of low frequency is proportional to the cube of the propagation distance, and the power loss of high frequency is proportional to the square of the propagation distance, high frequency can also be used for tag tracking and positioning.Antenna technology: Due to limitations in application scenarios, RFID tags usually need to be attached to the surfaces of different types and shapes of objects, or even need to be embedded inside the object. At the same time, the tag and reader antennas also play the role of receiving and transmitting energy respectively. Efficiently sending and receiving data places stringent requirements on antenna design. The antenna structure determines the antenna pattern, polarization direction, impedance characteristics, standing wave ratio, antenna gain and operating frequency band and other characteristics. Current research on RFID antennas mainly focuses on the effects of antenna structure and environmental factors on antenna performance, such as research on patch antennas, inverted F-shaped antennas, and Sierpinski fractal structure antennas.Low power consumption technology: Whether it is an RFID module working in an active or passive mode, in order to extend the life of the card, expand the application scenarios and improve the identification distance of the tag, one of the most basic requirements is low power consumption. In practical applications, reducing power consumption is as important as ensuring a certain effective communication distance. Therefore, the chips in the tags generally adopt very demanding low-power processes and high-efficiency energy-saving technologies. For example, [sleep mode] design technology is used in circuit design, and SMIC 0.18 um standard CMOS process design is used in hardware to realize memory and current-limited ring oscillator with full CMOS structure.Packaging technology: Since antennas, chips and other special components need to be installed in RFID tags, special packaging technology and specialized equipment are required to ensure the size, thickness, flexibility of the tag and the safety of the chip circuit in the high-temperature and high-pressure process. The packaging of labels is not only limited by standard shapes and sizes, but its composition also varies widely, and even requires special design according to various requirements.Positioning and tracking technology: The development of RFID technology provides a new solution for spatial positioning and tracking services, which is mainly used in indoor positioning areas where GPS is difficult to apply. The RFID positioning and tracking system mainly uses the tag's unique identification characteristics of the object to measure the spatial position of the object based on the strength of the radio frequency signal between the reader and the tag. Typical RFID positioning and tracking systems include the Cricket system developed by the MITOxygen project, the LANDMARC system of Michigan State University, and the RADAR system of Microsoft Corporation. This technology has been widely used to locate and track people in mines.Anti-collision technology: With the emergence of active tags and the application of RFID technology in high-speed moving objects, there is an urgent need for readers to efficiently and quickly identify a large number of tags within a limited time. This will cause channel contention problems, which require anti-collision algorithms to solve. Anti-collision algorithms are divided into two types: reader-writer and tag anti-collision algorithms. The tag anti-collision algorithm is to solve the problem of multiple tags communicating with the reader at the same time within the effective communication range of the reader. In the high frequency (HF) band, tag anti-collision algorithms generally use ALOHA and related algorithms. In the ultra-high frequency (UHF) band, binary search algorithms are mainly used to avoid collisions. Commonly used anti-collision algorithms take a long time to identify and cannot meet the identification requirements for high-speed moving tags. Although most new algorithms have shorter recognition times, they have higher requirements on tag design. For example, they need to add random number generators, registers or delays, etc., which are difficult to meet the low-cost requirements of system design. Therefore, while maintaining a certain complexity and cost, minimizing search time and improving recognition efficiency are the directions and trends of anti-collision algorithm research.Security technology: With the development of RFID technology and its application in military, security and financial fields, RFID-related security technology has become more important to protect information security and user privacy. With the continuous development of cryptanalysis and the emergence of various [hackers], RFID systems based on traditional security technologies are under increasingly serious threats. Due to the particularity of RFID devices, such as limited computing power, limited storage space and power supply, special requirements are put forward for the security design of RFID systems. Therefore, designing secure, efficient, and low-cost RFID security protocols remains a challenging research topic worldwide.(4) System application. The technical advantages of RFID have broad application prospects. Current typical applications include: access control, animal husbandry, air parcel identification, logistics management, logistics management, mobile commerce, product anti-counterfeiting, sports timing, ticket management, parking lot control, production line automation, document tracking management, vehicle anti-theft material management, etc. In summary, it can include the following areas.Commercial supply chain applications: The application of RFID technology in commercial supply chains will be the most extensive and in-depth application among all its application fields. It is also the most technically difficult and difficult application to implement. Because it is necessary to affix a label to all goods, this not only requires high label costs, but also requires back-end management systems and software that can process large amounts of data quickly and efficiently.Public transportation management application: Public transportation management is the earliest and most successful field where RFID technology is applied. The main applications involved include: electronic tickets, non-stop toll collection and vehicle management and tracking.Identification: Tags can be embedded in various valid documents such as ID cards, passports, and work permits to verify and identify personnel. They can also be placed in tubes and implanted in animal skins to track, research, and protect animals.Anti-counterfeiting application: RFID technology is applied in the field of anti-counterfeiting and has the advantages of fast identification, difficulty in counterfeiting, and low cost. If security authentication and encryption functions are added, it can greatly increase the difficulty and cost of counterfeiting, making it more difficult for counterfeiters to retreat. To prevent counterfeiting and facilitate banknote transaction processing, Japan and Europe are experimenting with embedding tags in yen and euros.Logistics management: In order to reduce logistics costs, improve transportation efficiency, and ensure that items will not be omitted or lost during transportation and circulation, the entire logistics process needs to be monitored and managed. The current application of RFID technology in the logistics field is mainly focused on the following aspects: railway and highway freight dispatching, container identification and tracking, automatic identification and processing of items and packages, etc.

This anti-theft device uses an electronic tag with only 1 bit of storage capacity to indicate whether the product has been sold. This electronic tag is not only cheap, but also can effectively prevent theft.From 1971 to 1980, RFID technology and product research and development were in a period of great development, and various RFID technologies and tests were accelerated. In terms of industrial automation and animal tracking, some of the earliest commercial applications and standards have emerged, such as industrial production automation, animal identification, and vehicle tracking.From 1981 to 1990, RFID technology and products entered the commercial application stage and began to be used on a large scale. However, different countries have different focuses on the application of radio frequency identification technology. The United States focuses on traffic management and personnel control, while Europe mainly focuses on animal identification and applications in industry and commerce.From 1991 to 2000, the number of manufacturers and applications using RFID technology increased day by day, and mutual compatibility and connectivity became the bottleneck that plagued the development of RFID technology. Therefore, the standardization issue of RFID technology has attracted increasing attention. It is hoped that through a globally unified RFID standard, radio frequency identification products will be more widely used and become an important part of people's lives.RFID technology products and applications entered a stage of rapid development after 1990. The American TI (Texas Instruments) began to become a pioneer in RFID and established the Texas Instruments Registration and Identification System (TIRIS). Currently known as TI-RFIS (Texas Instruments Radio Frequency Identification System), this is a major platform for RFID application development.In 1991, the world's first open highway electronic toll collection system was established in Oklahoma, USA. The vehicle's RFID electronic tag information is bound to the detection point location information and the car owner's bank card, and stored in a computer database. The car can pass through the toll detection point at high speed, and the fee can be automatically deducted from the car owner's bank card, and there is no need to set up lifting railings to block or cameras to capture the license plate.Lufthansa uses contactless radio frequency cards as air tickets, changing the traditional way of purchasing and selling air tickets and simplifying airport security procedures.In China, the city of Shanghai has installed an automatic road maintenance toll collection system based on RFID technology. Guangzhou and Foshan have applied RFID systems to open highways to automatically charge high-speed vehicles to improve vehicle passing efficiency and alleviate highway bottlenecks.In the mid-1990s, the Automatic Railway Identification System (ATIS) built by the Ministry of Railways of China used RFID technology to realize [automatic copying of train numbers for trucks]. Ground identification equipment (AEI) is installed at all section stations, marshalling stations, large freight stations and boundary stations to accurately identify running trains and vehicle information. On this basis, a computer automatic report collection system was established to store information such as railway train numbers, locomotive and freight car numbers, identification, attributes and locations. Real-time and autonomous statistics of railway vehicle management systems have been realized, becoming one of the most typical applications of RFID technology. Especially since high-speed railway trains began to operate, it is particularly necessary to use RFID technology for automatic, fast, and efficient management to reduce the probability of train accidents.In 1999, the Auto-ID Center of the Massachusetts Institute of Technology formally proposed the concept of Electronic Product Code (EPC). The combination of the concept of EPC, RFID technology and Internet technology will build a ubiquitous Internet of Things. Especially in recent years, IBM has proposed the concept of smart earth. After being affirmed by President Obama, the concept attracted widespread attention around the world.After 2001, the variety of RFID products has become more abundant, and standardization issues have attracted more and more attention. The application scale of the industry continues to expand, active tags, passive tags and semi-passive tags have all been developed, and the cost of tags continues to decrease. Wal-Mart, the world's number one retailer, announced the widespread use of RFID and the U.S. military announced that all military supplies would be identified and tracked using RFID, which greatly promoted the research and application of RFID technology and enriched and improved the theory of RFID technology.Since the beginning of the 21st century, with the continuous reduction of the cost of RFID tags and reading equipment, RFID technology has been more widely used, and some people even call it the terminator of bar codes. RFID technology is also used in medical care, electronic ticketing, access control management, etc. Several large retailers and some government agencies have mandated that their suppliers must have RFID tags on boxes and pallets of products shipped from distribution centers.In August 2009, former Premier Wen Jiabao proposed the concept of Perceiving China when he visited the Wuxi Internet of Things Industry Research Institute to inspect the construction of the Internet of Things. RFID technology will definitely form the front-end data collection platform of the Internet of Things together with the sensor network, and is the main component of the Internet of Things technology. Many people in the industry define 2010 as the first year of the Internet of Things.With the increasing informatization of society and the continuous advancement of science and technology, people have higher and higher requirements for work efficiency and automation. RFID technology combined with Internet, communication and computer technology can realize the tracking and information sharing of items on a global scale. Applying it to industries such as logistics, manufacturing and public information services can greatly improve management and operational efficiency and reduce costs. With the continuous improvement, development and maturity of related technologies, the RFID industry will become an emerging high-tech industry group and a new highlight of national economic growth.Current RFID research mainly focuses on technical standards, tag costs, key technologies and system applications.(1)Technical standards. In order to standardize the development, design and mass production of tags and readers and solve the interconnection and compatibility issues of RFID systems, RFID technology must be standardized. The standardization of RFID is an important issue that needs to be solved urgently. Countries and relevant international organizations are actively promoting the formulation of RFID technical standards. At present, there are no complete international and domestic standards for RFID. The standardization of RFID includes identification encoding specifications, operating protocols, and application system interface specifications. The identification encoding specifications include identification length, encoding method, etc.; the operation protocol includes air interface, command set, operation process and other specifications. The current main RFID technical standards include the European and American EPC standard, the Japanese UID (Ubiquitous ID) standard and the ISO 18000 series of standards.(2) Label cost. Tag cost is the key to limiting the success of commercial applications of RFID technology. RFID tags are mainly composed of IC chips, antennas and packages. According to the survey, the average price of passive HF band tags in 2003 was 91 cents, and the average price of UHF band tags was 57 cents. Some people predict that in the case of mass production, the production cost of RFID tags can be reduced to as low as 5 cents. By then, RFID technology will enter all areas of people's lives and provide people with cheaper, more efficient and more convenient services.(3) Key technologies. Research on key RFID technologies mainly focuses on frequency selection, antenna technology, low-power technology, packaging technology, positioning and tracking, anti-collision and safety technology, etc.Frequency selection: A key issue in RFID technology is the selection of operating frequency. The selection of operating frequency needs to be suitable for different applications and take into account the relevant regulations on the use of radio frequency bands and transmission power in various countries. The current working frequency of RFID spans multiple frequency bands, and different frequency bands have their own advantages and disadvantages. It affects not only the performance and size of the tag, but also the price of the tag and reader. In addition, differences in radio transmission power will also affect the range of the reader. To expand wireless coverage, the size of the tag antenna must be expanded. Low-frequency bands have relatively low energy, low data transmission rates, and limited signal coverage. However, the production cost of low-frequency tags is relatively low and comes in various shapes, making it easy to attach to the objects being identified and tracked. The high-frequency band has relatively high energy and is suitable for long-distance applications. At the same time, the data transmission rate in the high-frequency band is relatively high and the communication quality is good. Its disadvantage is that it is easily blocked by obstacles, easily affected by factors such as reflection and human body disturbance, and it is difficult to achieve full area coverage of the signal. Since the power loss of low frequency is proportional to the cube of the propagation distance, and the power loss of high frequency is proportional to the square of the propagation distance, high frequency can also be used for tag tracking and positioning.Antenna technology: Due to limitations in application scenarios, RFID tags usually need to be attached to the surfaces of different types and shapes of objects, or even need to be embedded inside the object. At the same time, the tag and reader antennas also play the role of receiving and transmitting energy respectively. Efficiently sending and receiving data places stringent requirements on antenna design. The antenna structure determines the antenna pattern, polarization direction, impedance characteristics, standing wave ratio, antenna gain and operating frequency band and other characteristics. Current research on RFID antennas mainly focuses on the effects of antenna structure and environmental factors on antenna performance, such as research on patch antennas, inverted F-shaped antennas, and Sierpinski fractal structure antennas.Low power consumption technology: Whether it is an RFID module working in an active or passive mode, in order to extend the life of the card, expand the application scenarios and improve the identification distance of the tag, one of the most basic requirements is low power consumption. In practical applications, reducing power consumption is as important as ensuring a certain effective communication distance. Therefore, the chips in the tags generally adopt very demanding low-power processes and high-efficiency energy-saving technologies. For example, [sleep mode] design technology is used in circuit design, and SMIC 0.18 um standard CMOS process design is used in hardware to realize memory and current-limited ring oscillator with full CMOS structure.Packaging technology: Since antennas, chips and other special components need to be installed in RFID tags, special packaging technology and specialized equipment are required to ensure the size, thickness, flexibility of the tag and the safety of the chip circuit in the high-temperature and high-pressure process. The packaging of labels is not only limited by standard shapes and sizes, but its composition also varies widely, and even requires special design according to various requirements.Positioning and tracking technology: The development of RFID technology provides a new solution for spatial positioning and tracking services, which is mainly used in indoor positioning areas where GPS is difficult to apply. The RFID positioning and tracking system mainly uses the tag's unique identification characteristics of the object to measure the spatial position of the object based on the strength of the radio frequency signal between the reader and the tag. Typical RFID positioning and tracking systems include the Cricket system developed by the MITOxygen project, the LANDMARC system of Michigan State University, and the RADAR system of Microsoft Corporation. This technology has been widely used to locate and track people in mines.Anti-collision technology: With the emergence of active tags and the application of RFID technology in high-speed moving objects, there is an urgent need for readers to efficiently and quickly identify a large number of tags within a limited time. This will cause channel contention problems, which require anti-collision algorithms to solve. Anti-collision algorithms are divided into two types: reader-writer and tag anti-collision algorithms. The tag anti-collision algorithm is to solve the problem of multiple tags communicating with the reader at the same time within the effective communication range of the reader. In the high frequency (HF) band, tag anti-collision algorithms generally use ALOHA and related algorithms. In the ultra-high frequency (UHF) band, binary search algorithms are mainly used to avoid collisions. Commonly used anti-collision algorithms take a long time to identify and cannot meet the identification requirements for high-speed moving tags. Although most new algorithms have shorter recognition times, they have higher requirements on tag design. For example, they need to add random number generators, registers or delays, etc., which are difficult to meet the low-cost requirements of system design. Therefore, while maintaining a certain complexity and cost, minimizing search time and improving recognition efficiency are the directions and trends of anti-collision algorithm research.Security technology: With the development of RFID technology and its application in military, security and financial fields, RFID-related security technology has become more important to protect information security and user privacy. With the continuous development of cryptanalysis and the emergence of various [hackers], RFID systems based on traditional security technologies are under increasingly serious threats. Due to the particularity of RFID devices, such as limited computing power, limited storage space and power supply, special requirements are put forward for the security design of RFID systems. Therefore, designing secure, efficient, and low-cost RFID security protocols remains a challenging research topic worldwide.(4) System application. The technical advantages of RFID have broad application prospects. Current typical applications include: access control, animal husbandry, air parcel identification, logistics management, logistics management, mobile commerce, product anti-counterfeiting, sports timing, ticket management, parking lot control, production line automation, document tracking management, vehicle anti-theft material management, etc. In summary, it can include the following areas.Commercial supply chain applications: The application of RFID technology in commercial supply chains will be the most extensive and in-depth application among all its application fields. It is also the most technically difficult and difficult application to implement. Because it is necessary to affix a label to all goods, this not only requires high label costs, but also requires back-end management systems and software that can process large amounts of data quickly and efficiently.Public transportation management application: Public transportation management is the earliest and most successful field where RFID technology is applied. The main applications involved include: electronic tickets, non-stop toll collection and vehicle management and tracking.Identification: Tags can be embedded in various valid documents such as ID cards, passports, and work permits to verify and identify personnel. They can also be placed in tubes and implanted in animal skins to track, research, and protect animals.Anti-counterfeiting application: RFID technology is applied in the field of anti-counterfeiting and has the advantages of fast identification, difficulty in counterfeiting, and low cost. If security authentication and encryption functions are added, it can greatly increase the difficulty and cost of counterfeiting, making it more difficult for counterfeiters to retreat. To prevent counterfeiting and facilitate banknote transaction processing, Japan and Europe are experimenting with embedding tags in yen and euros.Logistics management: In order to reduce logistics costs, improve transportation efficiency, and ensure that items will not be omitted or lost during transportation and circulation, the entire logistics process needs to be monitored and managed. The current application of RFID technology in the logistics field is mainly focused on the following aspects: railway and highway freight dispatching, container identification and tracking, automatic identification and processing of items and packages, etc.

What are the applications of RFID technology in smart manufacturing?Since the popularization of RFID technology, RFID has been used in a wide range of applications. Initially, it was mainly used in logistics. However, since its development, RFID applications can be seen in retail, logistics, transportation, medical care, manufacturing, etc. Although RFID technology is no longer a new technology, with the advent of the smart era, the industry has continued to develop various RFID application scenarios based on market demand in recent years. In the case of smart manufacturing, in view of the demand for resources and improved cost efficiency, manufacturers have also begun to adopt RFID technology to achieve applications such as real-time location tracking, asset or personnel monitoring, process control on production lines, and supply chain management. Let's take a look at the applications of RFID technology in smart manufacturing.1. Application of RFID technology in smart productsRFID technology combined with smart boards can realize full-cycle information management from design, production, sales, inspection, diagnosis and maintenance, information statistics, scrapping, operation information record feedback, diagnosis and analysis. It is of great value to enhance the intelligent image of products and realize the intelligentization of products throughout their life cycle.2. Application of RFID technology in smart logistics(1) Supply chain vehicle guidance and unloading managementThrough RFID technology, combined with the material supply needs of the factory area, it can realize the reservation, queuing, identification of factory supplier vehicles, and intelligent allocation of unloading resources in the factory area. Just like the bus ticket booking system, before arriving at the station (factory), the supplier makes an appointment and queues (purchases tickets) through the online appointment system. After arriving at the factory (station), follow the signs to the reserved unloading space to unload (wait and get on the bus) ).Currently, the Malong base of a well-known domestic brand of microwave ovens has implemented a material-pull supply chain model by deploying and implementing a supply chain vehicle guidance and unloading management system. Through the RFID system, we can understand the status of logistics resources in the entire factory area, channelize the logistics resources in the factory area, realize the entry time of supply chain vehicles into the factory, unloading resource arrangement guidance and time control, and improve the utilization rate of logistics resources in the factory area. Through the unified deployment and guidance of vehicles and unloading resources in the factory area, the factory has increased the utilization rate of logistics resources to more than 30%, and the delivery accuracy has increased to more than 15%.(2) Material distribution turnover box managementThe application of RFID technology to logistics turnover box management can greatly improve the operating efficiency of the logistics system and realize digital warehousing management (warehousing location management, rapid real-time inventory), etc., making management more scientific, timely and effective, and ensuring high-quality data exchange in the supply chain. This will bring about a significant improvement in logistics efficiency, thereby reducing the overall cost of the system.In Factory Building No. 18 of a state-owned enterprise, Honglu RFID readers are installed at all material distribution outlets, and RFID pickers are installed beside the assembly line. All material incoming and outgoing and line-side picking information will be collected in a timely manner and fed back to the backend system. The intelligent identification system for palletizing warehouses can realize transparency and intelligent guidance of the distribution process through intelligent components such as automatic warehouses, RFID smart trolleys, and RFID pallets, and improve the efficiency and accuracy of assembly material distribution.3. Application of RFID technology in smart workshops(1) Tool life cycle management and controlAs we all know, the purpose of tool management and control is to realize the information management of the tool life cycle and to understand the use and inventory status and location of the tool in a timely manner. Before the tools are purchased and stored in the warehouse, RFID electronic tags are installed on the tools as the unique identification information of the tools. During the scheduling and use of tools, by collecting tool information in a timely manner through RFID reading and writing equipment, you can clearly understand in the system whether the tool has been loaded, the specific corresponding machine tool, and the cycle and duration of use. By tracking the position and usage status of the cutting tools in a timely manner, companies can promptly understand the wear and tear of the cutting tools and replace them to ensure the safety of the cutting tools.A domestic heavy-duty machine tool company uses an RFID reader to promptly collect machine tool RFID tag information to understand tool usage status data, and promptly replaces tools based on the tool wear status feedback system. Improve the safety of tool use and ensure that machine tool processing production efficiency is at its most efficient state.(2) Production line mixed flow manufacturingWith the growth of users' personalized needs, selection and customization have gradually become a trend in the industrial production of manufacturing companies. The mixed assembly line production model of mixed flow manufacturing can well meet the personalized customized selection production needs. Mixed flow manufacturing is a production method in which enterprises produce multiple products on one assembly line within a certain period of time. Several product varieties with basically the same process flow and production operation methods are scientifically arranged and put into production on an assembly line in a rhythmic and proportional manner. Mixed continuous flow production is based on a comprehensive balance of variety, output, working hours, and equipment load.By installing RFID electronic tags on complex parts and pallets, and installing RFID industrial readers and writers on processing equipment and lines, intelligent communication between products and equipment is achieved, effectively avoiding many problems such as chaotic process management caused by untimely data collection. Provide data support for MES through timely collection of work-in-progress status and production process status, ensuring that MES can timely produce and schedule each workstation. Keep each workstation busy in a cycle to complete the maximum amount of operations, thereby reducing idle time and improving productivity.At present, an automobile company has installed RFID tags on the cylinder block and head processing production line to achieve the mixed-flow production of more than 6 types of cylinder blocks. The quality data and process data of the entire production line are effectively collected. A certain brand of home air conditioners installed RFID tags on the factory's flexible assembly lines, processes, and work boards to automatically collect data during the home appliance assembly process, increasing the data collection rate to 99%. Manual barcode scanning events are reduced by 5 minutes for a single product on each line, and the MES data accuracy rate is increased to 90%.(3) Intelligent mold maintenance managementA company in Dongguan that focuses on the production of electrode tubes has improved CNC processing efficiency, reduced warehouse personnel, reduced measuring personnel, and increased EDM utilization by more than 20% by opening up the information flow and manufacturing flow from mold design to manufacturing.The specific implementation method is to install RFID tags on each electrode tube to control the entire process of transistor storage, production, measurement and discharge. Through the collection of inventory, configuration, and on-site data, it extends from the design of the electrode to the entire process of manufacturing, measurement, and use, allowing data and manufacturing to interact seamlessly, realizing automation and unmanned operation of the entire process.With the development of the Internet of Things, intelligent production has gradually made breakthroughs, which have brought great benefits to intelligent manufacturing by improving product quality, improving production efficiency, and subverting inherent thinking. An intelligent clothing production line only takes 22 seconds to produce a piece of clothing, and a production line can be operated independently by only one worker, so the production line can produce about 800,000 pieces of clothing a day. This data was completely unimaginable before, but now it has been achieved.
