Research on asset management system based on RFID Internet of Things technology

With the development of science and technology, the Internet has become the trend of the times. RFID Internet of Things technology has also developed based on the Internet. Using RFID Internet of Things technology to effectively manage assets can ensure the normal operation of the enterprise, improve work efficiency, save resources, and effectively avoid the safety hazards caused by human management in traditional asset management. With the development of enterprises and the increase in the number of assets, traditional asset management has been difficult to meet the actual needs. Relying on RFID Internet of Things technology to effectively manage assets can ensure the safety of asset management, improve work efficiency, and reduce the cost of enterprise asset management. 1. Overview of Internet of Things Technology The Internet of Things refers to a network technology that connects objects and the Internet through information sensing devices to exchange and communicate information to achieve intelligent identification, positioning, monitoring and management. The use of RFID Internet of Things technology is a technology that uses radio frequency signals to achieve contactless information transmission through spatial coupling to achieve identification purposes. The asset management through RFID Internet of Things technology is to activate the electronic tag through the radio frequency signal of RFID, so as to obtain the asset data and effectively manage the assets. 2. Advantages of using RFID Internet of Things technology to manage assets 2.1 Asset registration is more accurate Traditional asset management enters information manually, which may cause errors in asset data due to human factors, and finally cause chaos in the entire asset database. Enterprises also need to hire professional personnel to enter assets, which is also an expense for enterprises; some asset entry staff lack a sense of responsibility and perfunctorily do the entry work, resulting in serious errors in the data, which is not conducive to the development of subsequent work and seriously affects work efficiency. The management of assets through RFID Internet of Things technology can effectively avoid the mistakes caused by human factors in traditional asset management. Asset registration can complete long-distance data collection and modification through RFID reading and writing technology, and can record asset information in detail to ensure the accuracy of asset registration and the reliability of data. The use of RFID Internet of Things technology to manage assets can save labor costs, ensure the accuracy of asset data, improve work efficiency, and promote the development of enterprises.2.2 It is conducive to improving the security of assetsRFID can automatically sense and locate equipment. If the asset is illegally taken out, the RFID will issue an alarm in time, and the background can know the asset situation in time and deal with it in time. This effectively improves the security of assets, prevents the loss of assets, and saves costs for enterprises.3. Implementation of IoT-based asset management technology 3.1 QR code management module When managing assets, you can use QR codes to match asset information. One QR code corresponds to one asset information. If you want to find a certain asset information, just scan the QR code. When changing the asset information, the QR code must also be updated and replaced. If the asset information is abolished, the corresponding QR code must also be abolished to prevent the asset information from being disordered, which is not conducive to asset management. 3.2 Daily asset management module The use of QR codes by asset equipment is conducive to the effective management of assets. Asset managers can query and change asset information by scanning QR codes and update asset information in time. The query of asset information can not only be operated through the computer, but also through the mobile device to scan the QR code, which is very convenient. The asset manager queries the asset information through the mobile device, and the mobile application will also have the query record of the asset manager, which can supervise the behavior of the asset manager to a certain extent to ensure the security and accuracy of the asset information. 3.3 Structure of the asset management system based on the Internet of Things Use RFID technology to tag the asset equipment, and effectively manage the asset information through the RFID tag. RFID can obtain the target information by identifying the tag through radio signals without contacting the target, but this requires high requirements for RFID technology, and special equipment is required, which is costly. Scanning the QR code can obtain asset information, and it can be scanned by mobile devices, which is very convenient and practical. Query and manage asset information anytime and anywhere through mobile devices, which improves work efficiency. 4. Application of RFID technology in asset management 4.1 To improve work efficiency, manage the entire life cycle of fixed assets When entering asset information, the asset manager will attach the electronic tag to the asset equipment and scan the electronic tag with RFID to enter the asset information. When the asset manager operates the asset information, RFID will automatically scan the electronic tag, read the asset information, and send the asset information to the server for processing, so that the assets can be tracked and managed. In order to achieve full electronicization and intelligent management of the entire life cycle of assets, RFID technology should be fully utilized.4.2 To optimize the monitoring of fixed assets and realize dynamic management of fixed assetsRFID technology can be used to update asset information in a timely manner. When fixed assets are used, the information of the user, the time of use, etc. is entered into the fixed asset management tag, and the used fixed assets are supervised in real time, thereby realizing dynamic management of fixed assets. The use of RFID technology can manage assets anytime and anywhere through mobile devices such as mobile phones and tablets. Asset managers can easily query and use assets, effectively simplifying the asset management process, effectively avoiding the tedious process and mistakes of manual asset information entry in traditional asset management, saving costs, and improving the efficiency of asset management. 4.3 Implement multi-level management to strengthen management awareness and clarify management responsibilities Asset management is very operational in enterprises, especially with the use of RFID technology, which can fully play the role of asset managers, divide the work of asset managers in detail, and effectively improve work efficiency. The information of each asset manager is entered into the asset management system. Asset managers need to identify their identities before they can operate and manage asset information, which also enhances the security of asset information. The use of RFID technology can fully play the role of asset managers' intelligence, strengthen their management awareness, clarify management responsibilities, and implement multi-level management. 4.4 To improve the efficiency of asset use and strengthen the daily management of assets In actual asset management, the lack of business communication and contact between management departments can easily lead to disorder in asset accounts; some enterprises lack a scientific and effective asset management system, and cannot enter effective asset information, resulting in loopholes in asset accounts, unable to effectively manage assets, and low work efficiency; in fixed asset management, the inventory of assets is not timely enough, or incorrect information occurs. If RFID technology is used to effectively manage assets, these situations can be avoided, resources can be effectively allocated, and the efficiency of asset management can be improved.4.5 Build a multi-purpose online supervision system for confidential carriers Build a multi-functional online supervision system that integrates active wireless, active wired, and passive wireless, which can adapt to different application scenarios. For example, large confidential carrier equipment (such as cipher machines) can use active wireless modules, small equipment (such as I cards, important files, etc.) can use passive wireless modules, and strong wireless interference environments can use active wired modules. RFID technology can realize real-time monitoring and intelligent management of confidential carriers. The system defines a safe area for confidential carriers, in which the equipment can move freely; at the same time, when the confidential carrier leaves the safe area without authorization, the management platform automatically alarms to prevent the confidential carrier from leaving the safe area without authorization. To solve the defects of the traditional manual management of confidential carrier loss prevention mechanism, an intelligent, efficient, and unattended confidential carrier loss prevention management solution is proposed to simplify the administrator's management procedures for confidential carriers, thereby improving the administrator's work efficiency. For the staff who supervise confidential carriers, permissions must be set, and the supervision system cannot be changed at will. Not all staff can supervise confidential carriers and set hierarchical permissions.5 Problems with asset management based on RFID Internet of Things technology 5.1 Lack of talents who can use RFID Internet of Things technology for asset management Although most companies in my country have majors and courses related to asset management and information technology, there are few talents who have both, and companies have not combined the majors related to these two aspects, which makes it lack of talents who can use RFID Internet of Things technology for asset management, and there is no talent to be cultivated. Or some professionals are not professional enough, have little practical experience, and appear amateurish in the actual operation process, which makes mistakes easy to occur, and is not conducive to improving work efficiency. Due to the rapid development of science and technology, information is updated quickly, which requires professional talents to learn and apply it to actual work, improve work efficiency, and promote the development of enterprises.5.2 Imperfect asset management system There is a lack of specific systems and standards for asset management, and there is no strict accountability system. If there are mistakes in asset management, how should the relevant responsible persons be punished and what systems should be followed for accountability? These are all issues that need to be resolved. my country's RFID Internet of Things technology level and advancement have not caught up with the most advanced in the world, and the use of RFID Internet of Things technology for asset management has high requirements, which makes it difficult to use RFID Internet of Things technology for asset management and development. It is easy to fall into development difficulties, and enterprises will spend more costs, which will eventually lead to low work efficiency and waste of resources. 5.3 The quality of asset management staff is not high and lacks a sense of responsibilityDue to cost limitations, the salary of asset management staff is low, and the staff's work enthusiasm is low. They will perfunctorily handle asset management work, and when problems arise, they will only shirk responsibility. Some asset management staff lack experience, are not very clear about asset management regulations, have limited skills, and may even operate improperly, seriously affecting work efficiency. 5.4 Lack of supervision of asset management Some asset management staff are not clear about the relevant asset management regulations when they are working, which leads to big problems in their work. Asset management staff should first have a thorough understanding of the relevant systems and implement them, mediate and supervise the contradictions and disputes arising from the work, and impose severe penalties on asset management staff who violate relevant regulations. In the process of supervision and inspection, some asset management staff, in order to save trouble, unilaterally pursue speed and ignore quality, omit some procedures, cut corners in work, do not strictly follow procedures, and even staff dereliction of duty and corruption. Some asset management staff engage in collusion between officials and businessmen, turn a blind eye to certain things, and do not strictly supervise according to relevant standards, which may lead to all previous efforts being wasted and seriously damage the interests of the enterprise. Some asset management staff will engage in corruption and tamper with asset data, resulting in errors in the data in order to profit from it. This requires asset management staff to set an example, strictly prohibit acts of corruption and embezzlement, and never accept bribes. They must be upright and honest.

What is UHF RFID multi-antenna identification system?

What is UHF RFID multi-antenna identification system?1、 OverviewRadio Frequency Identification (RFID) is a low-power short-range wireless communication technology. The full name is "Radio Frequency Identification (RFID)". The RFID identification system consists of at least two components: a radio frequency tag (Tag) and a reader/riter (Reader/riter or Interrogator). Radio frequency tags store electronic data in a specified format. In actual applications, electronic tags are attached to the surface of the object to be identified. The reader/riter can read the electronic data stored in the radio frequency tag without contact, thereby achieving the purpose of identifying the object information. The computer and network are combined to realize the collection, processing and remote transmission of object information and other control functions. The RFID identification system with an ultra-high frequency working frequency is applied in many fields such as production line automation management and warehouse management due to its strong tag recognition ability and fast data transmission rate. In the warehouse management application of large supermarkets, due to the diversity of packaging materials and the uncertainty of the number of items, some tags attached to the packaging of items will not be recognized, that is, there is a problem of blind recognition within the signal coverage range. The occurrence of this phenomenon seriously affects the promotion of RFID identification systems in warehouse management applications. In order to improve the tag reading rate and recognition reliability of RFID identification systems, domestic and foreign researchers have conducted a lot of research work, including a lot of application research on multi-reader antenna identification systems. By rationally deploying multiple antennas connected to readers at different spatial locations, the coverage area of ​​each antenna is complementary, reducing the reading and writing blind spots of the RFID identification system. This paper improves the multi-antenna solution proposed by Chen Hui et al. of Chongqing University from two aspects: spatial deployment of multiple antennas and optimization control algorithm of multiple antennas, further improving the tag reading rate and recognition reliability of RFID identification systems.2、Improvement plan for RFID multi-antenna identification system 2.1 Analysis of antenna deployment position The multi-antenna layout proposed by researchers such as Chen Hui is shown in Figure 1. The four antennas connected to the reader are deployed in the upper, lower, left and right directions of the identification area, and the order of antenna activation is ANT1, ANT2, ANT3, and ANT4. The coverage ranges of the four antennas connected to the reader are complementary, reducing the identification blind area of ​​the reading and writing area. However, in actual applications, the RFID identification system is deployed in the channel, and the reader antenna below is difficult to deploy. If the antenna below the identification area is removed, the system's coverage of the identification blind area will be reduced. This paper takes into account that in the actual application of the RFID identification system, the orientation of the tags in the identification area is uncertain. The layout of deploying the reader antenna in the upper left, lower left, upper right and lower right directions is equivalent to the layout of the reader antenna distributed in the upper, lower, left and right directions, and solves the problem of difficult deployment of reader antennas in actual applications. The improved multi-antenna layout is shown in Figure 2. The relative position of the reader antenna and the tag antenna plays an important role in the distribution of blind spots in the system identification area. In the multi-antenna layout scheme in the figure above, the identification blind spots in the coverage area of ​​the ANTI antenna are not necessarily the blind spots of the other three reader antennas. Therefore, it can be said that multiple reader antennas are deployed at different locations around the system identification area to complement each other. This reader antenna spatial diversity scheme can effectively remove blind spots in the identification area. There are many ways to reduce the blind spots of RFID identification systems. Compared with other methods such as frequency diversity, the method of using spatial diversity can achieve a better effect of removing blind spots, because in the ultra-high frequency RFID working frequency band, the wavelengths of electromagnetic waves corresponding to different frequencies are not much different, and the final blind spot distribution is basically the same, and the effect of eliminating blind spots will not be very obvious.2.2 Analysis of multi-antenna control algorithm In practical applications, RFID identification systems are generally required to be able to identify all tags in the identification area without omission and to complete the entire identification process as quickly as possible. In a multi-antenna identification system, the time used for the identification process of each antenna is a basic antenna inventory cycle. When the system performance is tested with the maximum number of tags allowed by the identification system, the identification system can meet the requirement of no tag missed reading. However, in many practical applications, the number of tags that need to be identified is far less than the maximum number of tags allowed by the system. At this time, a situation will arise. When the basic inventory process of the first antenna is completed, all tags in the identification area have been identified. Then the time spent on the inventory process of the remaining three antennas is unnecessary, resulting in a waste of system resources. This paper improves the control method of multiple antennas in view of this situation, so as to improve the efficiency of the identification system. The key point of the multi-antenna control algorithm is to determine the order of antenna opening. Since the orientation of the tags in the system identification area is uncertain in practical applications, the first antenna to be started can be random. This paper sets ANTI as the first antenna to be turned on. Determining the second antenna to be turned on is a difficult point. This paper determines the second antenna to be turned on by analyzing the relative position of the reader antenna and the tag antenna. Li Peng and others from the University of Electronic Science and Technology of China conducted an experiment on the influence of the relative position of a single reader antenna and a tag antenna on the recognition rate. The experimental results show that in the process of relative position from parallel to vertical, the tag recognition rate gradually decreases. The recognition rate is the highest when the tag plane is parallel to the reader antenna plane, and the recognition rate is the lowest when the tag plane is perpendicular to the reader antenna plane. Based on this, it can be determined that ANT2 or ANT3 antenna is the most suitable as the second antenna to be turned on, because the tag perpendicular to the ANT1 antenna plane is parallel to the ANT2 and ANT3 antennas, ensuring that the tag perpendicular to the ANT1 antenna can obtain a higher reading rate during the inventory process of the second antenna. This paper sets the ANT2 antenna as the second antenna to be turned on. The order of turning on the third and fourth antennas refers to the process of determining the order of turning on the second antenna. Finally, the order of turning on the four antennas determined in this paper is ANT1, ANT2, ANT3, and ANT4. At the end of the basic inventory cycle of each reader/writer antenna, the set of tags recognized by the system after the inventory process of this reader/writer antenna is completed is compared with the set of tags recognized by the system before the inventory of this antenna. If new tags are recognized, it means that there may be tags that are missed by the recognition system. In order to reduce the possibility of unrecognized tags in the system, it is necessary to continue to open the next reader/writer antenna to read the tags; if no new tags are recognized after the inventory cycle of the reader/writer antenna is completed, this situation where no new tags are added is regarded as the end point of the entire recognition process of the system. Compare the sets of identified tags before and after the end of the system inventory. The larger the number of tags contained in their intersection, the lower the possibility of missed reading by the recognition system. The flowchart of the multi-antenna control algorithm is shown in Figure 3. The variable marked with A in the flowchart represents the set of tags recognized by a single reader/writer antenna. The multi-antenna control algorithm determines the antenna opening order based on the ideal model of random tag orientation. In actual applications, the orientation of tags may be concentrated in one or several directions. Therefore, statistically analyzing the orientation of tags and determining the antenna opening order based on this is also an important aspect to improve the efficiency of the recognition system. This paper recommends that each antenna be assigned a weight in actual applications. The initial weight is 0. After the recognition system completes the inventory of tags, the number of tags identified by the opened antennas is compared, and the weight of the reader antenna with the largest number of identified tags is added by 1. When the reader antenna opening order is initialized during the next inventory process of the recognition system, the opening order is determined by the weight of the reader antenna. If the weights are the same, it is determined according to the ideal model.3、Performance Analysis of UHF RFID Multi-antenna Identification System3.1 Parameters for Reliability Evaluation of RFID Identification SystemThe multi-antenna layout of RFID identification system can reduce the phenomenon of missed reading of tags when identifying multiple tags, improve the reliability of RFID identification system for multiple tags, and select the parameters that can indicate the reliability of the identification system from the parameters that appear in the inventory process of the multi-antenna identification system. This paper defines this parameter as the system reliability coefficient.Definition 1: The system reliability coefficient μ is the ratio of the number of tags N identified by all the opened antennas during the system inventory process to the total number of tags N identified by the system.In formula (1), ue10,11, this parameter reflects the situation that the identification system is affected by unreliable factors during the inventory process of tags. The smaller the parameter value, the greater the impact of unreliable factors on the identification system, and the lower the reliability of the system. Conversely, the higher the reliability of the identification system. When the value of U is 1, the reliability of the identification system is the highest. At this time, it can be considered that there is no missed reading during the entire inventory process.3.2 RFID identification system simulation analysisSystem simulation parameter settings: The number of tags to be identified is N=300, and the number of multiple antennas has been determined to be M=4. After the simulation parameters are determined, this paper conducts 100 system identification simulations and analyzes the simulation results.Setting of system simulation parameters: The number of tags to be identified is N=300, and the number of multiple antennas has been determined to be M=4. After the simulation parameters are determined, this paper conducts 100 system identification simulations and analyzes the simulation results. First, the relationship between the single antenna reading rate p and the number of tags identified by the system and the number of antennas activated is analyzed. The simulation results are shown in Figure 4. The probability p is the recognition rate of a single antenna to a tag, that is, the probability that each tag to be identified can be identified. The larger the value of p, the larger the intersection of the tag sets identified by all enabled antennas, and the less the identification system is affected by unreliable factors. Figure 4(a) is a curve showing the total number of tags identified by the system as a function of the single antenna reading rate p. This curve shows that the number of tags identified increases with the increase of the p value. After the p value is greater than 0.6, the total number of tags actually identified by the system is close to the number of tags to be identified, 300. Figure 4(b) is a graph showing the number of antennas actually turned on by the system as a function of the single antenna reading rate p. This graph shows that the number of antennas actually turned on by the system decreases as the p value increases. Two key points can be seen in Figure 4(b). When the p value is less than 0.5, the number of antennas actually turned on by the system is 4. When the p value is greater than 0.9, the number of antennas actually turned on by the system is mostly two. According to the characteristics of the multi-antenna control algorithm, the number of antennas turned on by the system is at least two. Therefore, when the p value is 1, the number of antennas turned on is also two. Figure 4(c) is a curve showing the change of the system reliability coefficient as a function of the single antenna reading rate p. This curve shows that the value of the system reliability coefficient u increases as the P value increases. That is, the larger the P value, the higher the system reliability. When the p value is less than about 0.4, the system reliability coefficient is close to 0. The relationship between the number of antennas turned on by the identification system and the system reliability coefficient is shown in Figure 5. Figure 5 is a graph showing the number of antennas actually turned on by the identification system as a function of the system reliability coefficient u. It can be seen from the figure that when the system reliability coefficient is less than 0.6, because the total number of antennas is 4, the number of antennas actually turned on by the system is the maximum number of 4. When the u value is greater than 0.8, the number of antennas turned on by the recognition system begins to show a trend of decreasing. From the above analysis of the recognition system simulation results, it can be seen that the RFID multi-antenna recognition system can improve the reliability of multi-tag recognition, and the introduction of multi-antenna control algorithm improves the efficiency of the recognition system. The system reliability coefficient u provides an indicator that can evaluate the reliability performance of the recognition system. 4、ConclusionThe UHF RFID multi-antenna identification system adopts the method of spatial diversity to reduce the reading and writing blind area of ​​the RFID identification system, thereby improving the reliability of the RFID identification system. The introduction of the multi-antenna control algorithm has also improved the system efficiency, achieved the purpose of quickly and reliably identifying a large number of tags, and provided a parameter that can be used to evaluate the reliability of the identification system, namely the system reliability coefficient. The simulation results show that the UHF RFID multi-antenna identification system has a significant effect on improving the reliability of multi-tag identification, which is an important aspect of the research and wide application of multi-tag leak-free identification technology.

Application of RFID in the military field

Application of RFID in the military field The innovation and application of information technology are driving a new military revolution. Only by taking the initiative in information acquisition, transmission and processing can we meet the requirements of real-time, accuracy and comprehensiveness of military information in various occasions. Developing a military Internet of Things based on RFID technology will promote the information construction of the troops, further improve command efficiency, enhance logistics support capabilities, and improve the troops' ability to perform tasks. 1. RFID technology and the Internet of Things 1.1 RFID technology RFID is the abbreviation of "Radio Frequency Identification". It is a non-contact automatic identification technology that automatically identifies the target object and obtains relevant data information through radio frequency signals. Identification does not require human intervention. RFID systems generally consist of three parts: electronic tags, readers and data management systems. RFID has the characteristics of non-contact identification, large data storage, not easy to wear, high-speed identification, and anti-collision, and is widely used in production and life. In recent years, with the continuous development of integrated circuits and communication networks, RFID technology has made new progress in chips, readers, antennas, label packaging and other links, and has further developed in the direction of miniaturization, practicality, low cost, and scale. At present, RFID has been widely used in my country, such as the second-generation ID card, Olympic tickets, electronic payment, book and file management, access control system and other fields. 1.2 Internet of Things The Internet of Things refers to a huge network formed by combining various information sensing devices, such as radio frequency identification (RFID) devices, infrared sensors, global positioning systems, laser scanners and other devices with the Internet. Its purpose is to connect all items to the network, realize intelligent identification and management, and achieve information interconnection and real-time sharing. The Internet of Things has three main characteristics: comprehensive perception, reliable transmission, and intelligent processing. 1.3 Military Internet of Things The military Internet of Things refers to a huge network formed by combining all military supplies (including various equipment) with the military intranet through various information sensing devices, such as radio frequency equipment, barcode equipment, sensors, global positioning systems, geographic information systems, electronic data exchange, laser scanning and other devices. Its purpose is to connect all military supplies to the network and realize the connection of military supplies to the ubiquitous network at any time and any place. 2 、Military Application of RFID Technology The application of RFID technology originated from the military, and the military field is the leader in RFID application. With the continuous development and maturity of RFID technology, its application field has gradually expanded and has been widely used. 2.1 Application of RFID Technology in Foreign Military The earliest application of RFID originated from the identification of fighter planes in World War II. The United States is a representative foreign military application of RFID. In recent years, in the large-scale military operations of the United States, RFID technology has been widely used for marking and identifying various materials and personnel. In the Gulf War in the early 1990s, due to the problems of unknown whereabouts of materials and excessive repeated supplies in the links of requesting, transporting, and distributing materials, a huge waste of resources was caused. During the Iraq War in 2003, the US Army learned the lessons of logistics support in the Gulf War and attached importance to the development of "full-capital visualization technology, making full use of the visualization logistics network built by RFID technology, making the US military's logistics supply capabilities unprecedentedly powerful, and can easily grasp the real-time information of all logistics supplies, realize the full tracking of logistics materials, and also enable the US military to achieve the transformation from "reserve logistics" to "distribution logistics". Due to the advantages of RFID and the continuous maturity of technology, many countries have also adopted RFID in military logistics, providing a powerful means for accurate and real-time tracking of military logistics support processes and improving material visualization. 2.2 Application of RFID technology in domestic military At present, two-dimensional barcode technology is widely used in the field of material support of our army. The main feature of the two-dimensional barcode is that it can represent information in both horizontal and vertical directions. It has the advantages of large amount of information, high reliability, strong confidentiality and anti-counterfeiting, and can represent images, Chinese characters and other text information. RFID technology is considered as a wireless version of barcodes. Compared with barcodes, it has the advantages of non-contact identification without human intervention, large data storage and the ability to modify card information, strong anti-pollution and durability, anti-collision, i.e. the card reader can identify multiple cards, high-speed identification, and flexible electronic tag shapes and product attachment methods. These features make it an efficient technical means for the visualization and real-time tracking of military supplies, providing effective support for daily management in peacetime and logistical support in wartime. RFID has been used in military camp management for access control management, which is a relatively mature application. In addition to verifying personal identity, it can also verify the legality of vehicles. Since electronic tags eliminate manual intervention in the tracking process, they can greatly improve work efficiency while saving a lot of manpower. Military vehicle license plates are a typical application of RFID technology. The military vehicle license plates replaced in December 2004 are embedded with contactless anti-counterfeiting radio frequency cards, and the basic parameter information of the vehicle is written inside. The authenticity can be identified through the identifier, and the use and management of the military vehicle license plates can be checked. RFID technology has also been gradually applied to the field of warehousing management of our army, such as the radio frequency identification system for transported materials and automated stereoscopic warehouses, which provides a convenient and flexible solution for automatically obtaining the visible information of assets in storage, transportation, and use, and greatly reforms the traditional logistics tracking method. RFID technology is applied to the automatic identification management of military firearms, providing a digital platform for the automatic identification and intelligent management of the entry and exit of military firearms, use and maintenance. 3. Main problems to be solved in the application of RFID technology in our army RFID technology and products have been applied in many practical fields in the civilian field, and the technology has matured. Due to the special requirements of the military, there are still many key technologies that need to be further developed. Combined with the practice of civilian products, RFID technology needs to focus on solving the following problems in military applications: 3.1 Coexistence of electronic tags and barcodes, and gradually realize the transition from barcodes to RFID At present, barcode technology has been widely used in our army, but compared with RFID technology, it has the disadvantages of small amount of information, easy damage, and short identification distance. At present, RFID is mostly used for outer packaging boxes and containers of equipment, such as warehouse pallets, etc. The electronic tags store information such as item specifications and codes, while barcodes are used for specific internal item components. Due to cost, frequency band, confidentiality and other reasons, it is not yet mature to completely replace barcodes with RFID. For a long time, the two will coexist at the same time, which requires full use of the advantages of the two, complementary use, and gradual transition to RFID. 3.2 Focus on strengthening the unification of standards from the perspective of military-civilian logistics integration At present, industry standards and related product standards are not unified. RFID electronic products using different standards are incompatible, so materials between RFID systems of different standards cannot be identified, which hinders the formation of product interoperability and data processing platforms. Standardization is the premise for truly realizing comprehensive informatization and the key to establishing a military-civilian logistics integration system. We should accelerate the establishment of our military RFID technology standard system, formulate standards and specifications such as information classification, indicator system, and various information coding codes, and integrate them with existing information systems to achieve information sharing. 3.3 Select appropriate electronic tags according to the use environment Select appropriate electronic tags according to the use environment. Due to the particularity of the military field, under complex environmental conditions, the frequency of the electronic tag cannot conflict with the frequency of other communication equipment, otherwise interference will occur. Therefore, it is required to have strong anti-interference ability and meet the needs of various environments. According to different working frequencies, RFID systems are generally divided into two categories: medium and low frequency bands and high frequency bands. High-frequency long-distance electronic tags are mainly used in the fields of automatic vehicle identification, bulk cargo tracking and monitoring, and are suitable for managing logistics and supply chain links. Low frequency is mainly used in access control management, animal tracking and management, production line automation and process control. Due to the particularity of the military field, it is required to have strong anti-interference ability and meet the needs of various environments. 3.4 Strengthen confidentiality awareness and strengthen RFID security management In military applications, security is an important issue that needs to be considered. The threats faced by RFID are mainly the leakage of equipment or component information in the electronic tag and the use of the unique identifier of the tag for tracking. If these problems exist, unimaginable consequences will occur. There are currently two types of RFID security technologies: one is to prevent the communication between the electronic tag and the reader by physical methods, and the other is to increase the tag security mechanism by logical methods. RFID security protection and cost are mutually constrained. The low-cost RFID circuit structure makes it difficult to implement existing encryption technology, and it can only be implemented with relatively expensive ones. Security is a challenging issue for military applications. It is necessary to design a safe and effective security technology solution based on the limited resources of the electronic tag, and only the best solution is to balance security and cost.

The working principle and process of industrial RFID readers.

The working principle and process of industrial RFID readers. RFID is the abbreviation of Radio Frequency Identification, which is a type of automatic identification technology. Its principle is to conduct non-contact data communication between the reader (also known as the reader, reader, etc.) and the tag to achieve the purpose of identifying the target and exchanging data. It is considered to be one of the most promising information technologies in the 21st century. 1. Working principle: The complete RFID system consists of three parts: reader, electronic tag and data management system. The basic working principle of RFID technology: After the tag enters the reading range of the reader, it receives the radio frequency signal sent by the reader, and sends the product information stored in the chip with the energy obtained by the induced current (passive tag or passive tag), or the tag actively sends a signal of a certain frequency (active tag or active tag). After the reader reads and decodes the information, it is sent to the central information system for relevant data processing. 2. RFID system workflow:The reader sends a radio frequency signal of a certain frequency through the transmitting antenna. When the radio frequency tag enters the working area of ​​the transmitting antenna, an induction current is generated, and the radio frequency tag obtains energy and is activated; the radio frequency tag sends its own encoding and other data information through the tag's built-in transmitting antenna; the system receiving antenna receives the carrier signal sent from the radio frequency tag, which is transmitted to the reader through the antenna regulator. The reader demodulates and decodes the received signal and then sends it to the background main system for related processing; the main system determines the legitimacy of the tag based on logical operations, makes corresponding processing and control for different settings, and sends out command signals to control the action of the actuator. The YANZEO SA810 UHF RFID Reader is a powerful long-range reader designed for parking gate access control systems. With a read range of up to 25 meters (98 feet) and a high-gain Circular Polarize Antenna , this reader can reliably identify and track RFID tags from a considerable distance. Its versatile communication interfaces, including RS485, Wiegand26/34, and USB, allow seamless integration with various access control systems and peripherals. Whether you need to manage vehicle access in a parking facility or monitor asset movements in a warehouse, the SA810 UHF RFID Reader offers a robust and efficient solution. Its rugged construction ensures reliable performance in demanding environments, while its user-friendly design simplifies installation and maintenance.

Application of RFID in Supply Chain Management

Application of RFID in Supply Chain Management The RFID technology system in business is composed of RFID tags and readers. RFID tags are integrated circuit I℃ chips with antennas, data is stored on I℃, and communicate with the outside through antennas. There are many types of RFID tags in terms of size, operation mode, accuracy, and cost. Different types can be selected according to the needs of different enterprises. RFID readers are composed of one or more antennas for receiving and sending signals and a microprocessor for decoding received signals. The processed data is connected to the ERP system host via conventional cables or local wireless networks WLEN. The reader can be made with a handheld terminal, or it can be fixed and installed in a certain location, such as the entrance of the factory, the door of the arrival warehouse, the shelf or the label information on the production line is sent and received through radio frequency. RFID does not require the visual connection required by barcodes between the object and the reader. Thus, the identification and information storage process can be completed without supervision. RFID can be read through packaging, transport containers and a variety of materials other than metal. Up to 12 RFID tags can be read at the same time. The application value of RFID technology in business From the perspective of a single enterprise, RFID technology has improved the enterprise's warehouse management system and ERP system, making the entry and exit of goods in and out of the warehouse more convenient and faster. RFID technology has strengthened and simplified the information of components and finished products used in production, warehouse receipt and delivery of goods, and goods received by customers, providing enterprises with more accurate, detailed and timely data than barcodes, and the collected data is of higher quality, without increasing costs, and even reducing operating costs. In addition, RFID identification technology can reduce the loss of goods in enterprises, better control distribution channels and distribution security, and improve after-sales service levels. From the perspective of the entire supply chain, the modern supply chain is a network composed of producers, distributors, retailers and third-party logistics, as well as information exchange systems such as products, raw materials, orders, and freight settlements established on this basis. RFID makes this information system public and standardized. RFID enables each enterprise in the supply chain to use and manage specific public information such as the situation of goods in the supply chain. These public information replaces the exchange of private information between supply chain partners, improves the flexibility of the entire supply chain, and enables enterprises to choose suitable partners in a larger range, which is convenient for improving the management synergy between supply chain partners. RFID application design in supply chain process 1、Supplier Suppliers can use RFID technology in the manufacturing process to complete the operation of automated production lines, realize the identification and tracking of raw materials, parts, semi-finished products and finished products on the entire production line, reduce manual identification costs and error rates, and improve efficiency and benefits. For example, on an assembly line that uses JT (JustinTime) to manage production in a timely manner, raw materials and parts must be delivered to the designated workstation on time. After using RFID technology, companies can quickly and accurately find the raw materials and parts required for the workstation from a wide variety of inventory by identifying electronic tags. In addition, RFID technology can also help managers issue replenishment information in a timely manner according to production progress, achieve balanced and steady production of the assembly line, and also strengthen quality control and tracking. After the product is completed, the supplier adds a radio frequency identification tag (RFID) to each product or box of goods it produces. It contains a unique product electronic code stored in the chip of the tag. These tags have a miniature radio frequency antenna. Through these tags, companies can automatically identify, count and track the goods. At the factory where the goods leave, the company installs an RFID reader. When the goods leave the factory, the RFID reader at the shipping port sends radio frequency waves to the RFID tags on the goods to activate these tags and power them at the same time. The tags then begin to revive and emit their respective ID numbers. The reader at the factory begins to read these tags to obtain the tag information and record it until all the tags have been read. 2、Delivery Center In the transportation process, RFID tags are affixed to the goods and vehicles in transit, and RFID receiving and forwarding devices are installed at some checkpoints on the transportation line. When the receiving device receives the RFID tag information, it is uploaded to the communication satellite together with the location information of the receiving place, and then transmitted to the transportation dispatch center by the satellite and sent to the database. In this way, the location of the goods can be known at any time to ensure the safety and integrity of the goods. In the distribution process, the use of radio frequency technology can greatly speed up the distribution speed and improve the efficiency and accuracy of the picking and distribution process, and can reduce labor and reduce distribution costs. If all goods arriving at the central distribution center are affixed with RFID tags, when entering the central distribution center, the pallet passes through a reader to read the label content on all the boxes on the pallet. The system checks this information with the shipping record to detect possible errors, and then updates the RFID tag to the latest storage location and status of the goods. In the warehousing process, when the traditional barcode warehousing operation is used, the goods are first moved to the receiving area, the type and quantity of the products are manually inspected, and then the operator uses a barcode scanner to scan the goods in turn as a warehousing record. When the goods are transported to the warehouse and the warehousing procedures are handled after the RFID technology is adopted, there is no need to open the package to check the goods inside because there is an RFID reader installed in the unloading area. You only need to check and confirm the corresponding purchase order, and then you can directly check and enter the warehouse. In this way, the entrance, inspection, warehousing record and cargo allocation operations are completed at one time, reducing the workload of handling and saving the time of warehousing and management. Similar to warehousing, when the goods are shipped out of the warehouse, there is also an RFID reader installed in the unloading area, so there is no need to open the package to check the goods inside, and you can directly inspect and accept the goods out of the warehouse. Under RFID technology, the verification and outbound records are completed in one step. When the reader reads the outbound goods, the detailed information of the goods, such as number, name, quantity, etc., will be displayed. The staff will select the corresponding items based on this information and check them at the same time. If the verification is correct, they can be shipped out immediately. It can be seen that the use of RFID technology shortens the operation process of entering and leaving the warehouse, and greatly reduces the equipment cost and labor cost required for handling. 3、Retailers When the goods arrive at the retailer, there is also an RFID reader installed at the retailer. Once the goods arrive, the retailer's retail business system will be automatically updated and the information of each box of goods will be recorded. That is, the retailer can automatically confirm the inventory of the goods, which is very accurate and reliable. When taking inventory of goods, since each packaging box and product is affixed with an RFID tag, the clerk only needs to hold the RFID reader and pass through all the shelves in turn, and the reader will automatically obtain the information recorded by all the tags, which will greatly reduce the phenomenon of omissions and deviations in traditional inventory operations and improve the accuracy and reliability of information. During the sales process, since the retail shelves are also equipped with RFID readers, when the goods are put on the shelves, the shelves can automatically identify the newly added goods. If the customer takes the goods, the shelves will send a replenishment information to the retailer's automatic replenishment system. From the customer's point of view, customers no longer have to wait in line for a long time to pay. They only need to swipe the card and push the selected goods out directly, because the reader installed at the door of the retail store can directly read the RFID tag of the goods to obtain the information of the goods and identify the goods purchased by the customer. Since the product electronic code in the RFID tag is the only mark of the goods, retailers can use the product electronic code to track the logistics of the goods and perform automated management based on the automatically captured information. Take WalMart as an example. WalMart has always been the main supporter of RFID technology. WalMart requires its top 100 suppliers to install RFID on all products shipped to major distribution factories before the end of next year. At the same time, all products shipped to various distribution points must also be equipped with RFID before January 1, 2006. In the future, our shopping at WalMart will be as follows: Suppose we push a shopping cart and choose in front of rows of shelves in Walmart supermarket. When we walk to the food area, we choose a brand of beer and continue to move forward, but suddenly notice another brand of beer. When we compare them, we put the former beer back and throw the latter into the car. In this half minute, the host reads the information that the former beer leaves and returns through the RFID tag, and transmits it back to the headquarters of this brand of beer company. When we walked out of the supermarket door with a full shopping cart of selected items, no one stopped us. This is because when we passed the cash register system at the door, the membership card on our shopping cart reported our identity, and the RFID reader instantly identified the quantity and price of all the goods, and the bank transfer system debited the corresponding amount from our account. In the past, supermarkets used barcodes to speed up the charging process. After consumers paid at the checkout counter, the magnetic stripes on the goods became ineffective. But unlike magnetic stripes, RFID tags can continue to be recognized outside the line of sight. WalMant will track the whereabouts of the product, and we will get better after-sales service. For WalMart, after using RFID product-level tags, if a certain product is in the store, the store staff can immediately track it through the tag. When a product is out of stock, the store staff can find out by scanning the RFID tag on the shelf with a scanner, and can also calculate the related products that replace the product. In addition, the use of RFID technology can enhance the store's security, environmental monitoring capabilities, traffic conditions monitoring capabilities, and customer behavior monitoring. It is not difficult to see that the popularization of RFID technology in commercial supply chains is inevitable and will play an indispensable role in our lives.

What is the future development trend of RFID technology?

What is the future development trend of RFID technology? The Internet of Things is another information industry revolution after computers, the Internet and mobile communications. As one of the important cores of the perception layer of the Internet of Things, RFID technology not only promotes the rapid development of the Internet of Things, but also promotes the application and development of RFID technology. A brief analysis of the future development trend of RFID technology! The Internet of Things industry is listed as an important strategic emerging industry to encourage development, and has created a good policy environment for the development of the entire Internet of Things industry. It provides policy guarantees for the development of my country's Internet of Things industry from investment and financing systems, taxation, industrial technology, exports, income distribution, talent attraction and training, procurement, intellectual property protection, industry organization and management. As an important part of the Internet of Things industry, the RFID industry also benefits from the strong support of policies. RFID is widely used, involving all aspects of social life, and can be applied in logistics, retail, manufacturing, clothing, medical, identity recognition, anti-counterfeiting, asset management, transportation, food, automobiles, military, financial payment and other fields. RFID has a significant effect on improving enterprise operating efficiency and reducing operating costs. At present, it is rapidly promoted in the fields of financial payment, identity recognition, traffic management and logistics, and is gradually being tried in retail, clothing and other fields. There is huge space for downstream applications. Compared with barcodes, RFID electronic tags that can store information and scan multiple tags at the same time have technical and functional advantages. However, the cost gap has always hindered the popularization of RFID technology. In recent years, with the advancement of technology and the gradual expansion of the scale of application, the cost of RFID electronic tags has been significantly reduced, which will contribute to the healthy development of the industry. The lack of uniformity in standards (especially standards for data format definitions) is the primary factor restricting the development of RFID. Each RFID tag has a unique identification code. If there are many different data formats and they are incompatible with each other, RFID products of different standards cannot be used universally, which is very unfavorable for the circulation of goods under economic globalization. The issue of data format standards involves the interests and security of each country. The United States, Japan, China and other countries have all formulated their own standards, and it is expected that many other countries will also begin to formulate their own standards. How to make these standards compatible with each other so that an RFID product can circulate smoothly around the world is an important and urgent problem that needs to be solved at present. RFID is a technology-intensive industry, and technicians are an important foundation for development. The broad market prospects have attracted a large number of new industrial robot system integration manufacturers, and the participation of a large number of companies has intensified the competition for high-end technical talents. At present, RFID enterprises are concentrated in RFID tag packaging, and the foundation of RFID chip design and manufacturing, which has the highest technical content and added value, needs to be continuously optimized. This field is still dominated by foreign brands and needs to be imported from foreign countries. The weakness of chip technology hinders the healthy development of the industry. In the era of Internet intelligence, traditional industries will accelerate the pace of optimization, which will greatly promote the demand for RFID applications. The application of intelligent technology has begun to empower all walks of life, and the industry intelligence has accelerated. RFID will better play its characteristics, and the RFID industry chain has been continuously improved. In the future, with the continuous breakthrough of RFID technology, more and more RFID application scenarios will appear to realize data collection automation.

Are RFID Blocking Wallets Worth It?

Are RFID Blocking Wallets Worth It? RFID-blocking wallets are supposed to prevent your RFID card information from being stolen. But do they really work? And even if they do, are the dangers real enough to make the purchase worthwhile? Let's find out. What is RFID Blocking? Radio frequency identification (RFID) technology uses energy from an electromagnetic field to power a small chip, which emits information in response. For example, the RFID chip in a credit card contains the information needed to authorize a transaction, and the RFID chip in an access card has a code to open a door or restricted system. Certain materials, especially conductive metals, prevent electromagnetic waves from passing through them. An RFID-blocking wallet has its card sleeves (or sometimes the entire wallet) made of a material that doesn't let radio waves pass through. That way, the chip won't activate, and even if it does, its signal won't pass through the wallet. The bottom line is that you can't read an RFID card through your wallet. Why should your card be blocked? RFID tags are passive devices that will happily send their information to anyone willing to listen. This sounds like a recipe for poor security, but RFID tags that can be scanned at a distance are not usually loaded with sensitive information. They are used to track inventory or packages, for example. It doesn't matter who reads the information because it's not a secret. Concerns about RFID cards are growing as more and more NFC reading devices make their way into the hands of the general population. NFC (Near Field Communication) is a technology very similar to RFID, with the main difference being range. NFC chips can only read at a range measured in inches. NFC is essentially a special type of RFID. It's how "swipe to pay" cards work with payment terminals equipped with NFC readers. If your smartphone is capable of contactless payments, it can also be used to read NFC cards. So what stops someone from using their phone to copy your NFC card? This is exactly the scenario that an RFID blocking wallet is supposed to prevent. The idea is that someone can simply hold their NFC reader close to your wallet and copy your card. They can then have the device copy the RFID information to make a payment. Are RFID Protected Wallets Worth It? There’s no doubt that the concept behind RFID-blocking cards is solid. A 2012 demonstration of how an Android phone could steal credit card details wirelessly left no one doubting the threat. The problem is, these kinds of attacks don’t seem to be happening in the wild. It makes sense that NFC skimming could be used against specific high-value targets carrying valuable information, but it’s not worth it to walk around a crowded mall and steal credit card information from random strangers. Not only is there a real physical risk of pulling off this specific heist in public, but it’s also much easier to steal credit card information using malware or phishing techniques. As a cardholder, you’re also protected from credit card fraud by the card issuers, none of which, as far as we know, require the use of an RFID-blocking wallet to qualify. So at most you’ll avoid a minor inconvenience when stolen funds are replaced. If you’re a high-value target, such as an employee with access cards to valuable or sensitive assets, then using an RFID-blocking sleeve or wallet is wise. So, an RFID-blocking wallet is worth it because this low-probability attack could be used against you. But we don’t think it should be a determining factor when choosing your next wallet unless you’re high risk. Then again, the best RFID blocking wallets are also great wallets. So why not?

Are RFID Blocking Wallets Worth It?

Are RFID Blocking Wallets Worth It? RFID-blocking wallets are supposed to prevent your RFID card information from being stolen. But do they really work? And even if they do, are the dangers real enough to make the purchase worthwhile? Let's find out. What is RFID Blocking? Radio frequency identification (RFID) technology uses energy from an electromagnetic field to power a small chip, which emits information in response. For example, the RFID chip in a credit card contains the information needed to authorize a transaction, and the RFID chip in an access card has a code to open a door or restricted system. Certain materials, especially conductive metals, prevent electromagnetic waves from passing through them. An RFID-blocking wallet has its card sleeves (or sometimes the entire wallet) made of a material that doesn't let radio waves pass through. That way, the chip won't activate, and even if it does, its signal won't pass through the wallet. The bottom line is that you can't read an RFID card through your wallet. Why should your card be blocked? RFID tags are passive devices that will happily send their information to anyone willing to listen. This sounds like a recipe for poor security, but RFID tags that can be scanned at a distance are not usually loaded with sensitive information. They are used to track inventory or packages, for example. It doesn't matter who reads the information because it's not a secret. Concerns about RFID cards are growing as more and more NFC reading devices make their way into the hands of the general population. NFC (Near Field Communication) is a technology very similar to RFID, with the main difference being range. NFC chips can only read at a range measured in inches. NFC is essentially a special type of RFID. It's how "swipe to pay" cards work with payment terminals equipped with NFC readers. If your smartphone is capable of contactless payments, it can also be used to read NFC cards. So what stops someone from using their phone to copy your NFC card? This is exactly the scenario that an RFID blocking wallet is supposed to prevent. The idea is that someone can simply hold their NFC reader close to your wallet and copy your card. They can then have the device copy the RFID information to make a payment. Are RFID Protected Wallets Worth It? There’s no doubt that the concept behind RFID-blocking cards is solid. A 2012 demonstration of how an Android phone could steal credit card details wirelessly left no one doubting the threat. The problem is, these kinds of attacks don’t seem to be happening in the wild. It makes sense that NFC skimming could be used against specific high-value targets carrying valuable information, but it’s not worth it to walk around a crowded mall and steal credit card information from random strangers. Not only is there a real physical risk of pulling off this specific heist in public, but it’s also much easier to steal credit card information using malware or phishing techniques. As a cardholder, you’re also protected from credit card fraud by the card issuers, none of which, as far as we know, require the use of an RFID-blocking wallet to qualify. So at most you’ll avoid a minor inconvenience when stolen funds are replaced. If you’re a high-value target, such as an employee with access cards to valuable or sensitive assets, then using an RFID-blocking sleeve or wallet is wise. So, an RFID-blocking wallet is worth it because this low-probability attack could be used against you. But we don’t think it should be a determining factor when choosing your next wallet unless you’re high risk. Then again, the best RFID blocking wallets are also great wallets. So why not?

How is RFID technology used in ports?

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.
