RFID technology plays a pivotal role in the development of the internet of things. This article will focus on the application of RFID technology in the internet of things from several industries.
The rise of the internet of things has driven the rapid development of RFID. According to estimates, the RFID market has grown from 60.9 billion yuan in 2016 to 110 billion yuan in 2019, with a 6-year compound growth rate of 14.5%. The application field of RFID products has been relatively mature. RFID can be seen in daily life applications such as electronic bills, mobile payment, and card access.
RFID technology plays a pivotal role in the development of the internet of things, which is mainly reflected in the perception layer of the internet of things. This article focuses on the following industries as examples:
In the field of transportation, RFID is most commonly used in the often-mentioned ETC system. The ETC system is the so-called "non-stop toll collection system", which can realize automatic charging without stopping the vehicle. The ETC system combines modern communication technology, electronic technology, automatic control technology, computer and network technology, and other high-tech as the leading.
When the RFID tag installed on the vehicle is close to the range of the ETC reader (usually 1-10 meters), the ETC reader emits a microwave query signal. After the RFID tag on the vehicle receives the query signal from the reader, this signal and the data information of the electronic tag itself (such as high-speed mileage, vehicle information, etc.) will be reflected back to the card reader. The biggest advantage of this is that it reduces the trouble of manual charging, improves the efficiency of vehicle clearance, and avoids the trouble of traffic jams.
The application of RFID in the hospital information system will significantly improve the efficiency of hospital asset operation and the level of medical services. The application in the following aspects is more mature.
(1) Management of the pharmaceutical supply chain
RFID tags can identify physical objects at any point in the manufacturing and distribution process. It can help pharmaceutical companies produce more types of more complex products in small batches, and monitor drugs at all nodes in the supply chain, like accurate target batch delivery, thereby reducing medical problems. Once problems occur, the traceability of the drug can be better realized.
(2) Medical monitoring
The hospital will wear a wrist tag for each patient. Medical staff only need to scan the label information with a handheld reader to know the patient information, the rescue of emergency patients will not be delayed, and there will be no accidents caused by the wrong identification of the injured. In the case of patient transfer, patient information can also be transmitted without error.
(3) Tracking and positioning application of important hospital assets and materials
Large medical centers generally have huge storage bases for important medical assets and medical items. Hospital logistics personnel need to find suitable items from thousands of materials according to orders every day. The use of RFID tags will make this search and verification process extremely fast and accurate, and the tags themselves can carry item-related information, which can increase the speed of the entire verification process by about 20 times.
The entire logistics system is closely related to RFID from the beginning of the labeling of goods into the warehouse, to the mid-term inventory counting, and the later out-of-warehouse allocation.
For example, when new goods are labeled and entered into the warehouse, the unique ID number or written data of the electronic tag can be compared to the "ID number" of the goods. The data includes the name of the goods, the time of purchase, the warehouse to which they belong, and the attributes of the goods.
People only need to scan the code with the reader to read the cargo information. This process also saves a lot of time for inventory counting. The staff only needs to hold the reader for regular inventory, read the label information of the goods at close range, and compare it with the background management system to know whether the goods information is consistent with the background system, if inconsistent. The system information can be amended on site.
Similarly, when the goods are out of the warehouse, the export gate RFID reader reads the goods tags to obtain the outbound information and verifies whether the product batch numbers and locations listed in the shipped products and outbound orders are correct. After the delivery is completed, if there are any problems with the goods in the future, you can also find out what problems have happened before the goods are delivered to the user through the traceability method.
With the rapid development of high technology, RFID (Radio Frequency Identification Technology) is widely used in the internet of things, medical care, security, transportation, and other fields, driven by the era of great interconnection. In recent years, RFID has also been widely used in the apparel industry, retail industry, and even gradually spread to other industries.
