RFID technology uses radio frequency for non-contact two-way communication to exchange data in order to achieve the purpose of identification. Compared with the traditional magnetic card, IC card or bar code identification method, RFID technology has the characteristics of long-distance and non-contact identification, and has strong adaptability to the environment. Through reasonable design, it can work in various harsh environments and has excellent identification effect. RFID identification does not require manual intervention, and is suitable for automatic data collection of the system. At the same time, it can identify high-speed moving objects and can identify multiple RFID tag labels at the same time, which is fast and convenient.
The basic feature of RFID technology is to use radio technology to realize the identification of stationary or moving objects, to achieve the purpose of determining the identity of the object to be identified and extracting the characteristic information of the object to be identified. At present, it has been widely used in many fields such as automobile production, transportation control management, industrial automation, warehousing and logistics. RFID technology applied in the truck frame management uses the advantages of RFID technology for intelligent management.
The RFID truck frame management system will be based on the successful application experience of RFID technology in other fields, combined with the own needs of international container truck frame management, based on the principles of automation, advancement, stability, and scalability, and centered on the core business requirements. Therefore, the automatic identification and tracking monitoring of the frame of the container truck can be realized. The core of this system is to install RFID readers and RFID antennas on the front of the container truck and to install RFID tag labels on the frame, so as to realize the monitoring and management of the frame through the reader's identification on the electronic tag labels.
Before the system is used, it is necessary to complete the initialization of the RFID tag label information, write the unique identification code of the frame into the RFID tag for trucks, and complete the establishment of the initial data information. After the container truck is started, the RFID reader begins to work; When the frame with the RFID tag label is connected to the front of the car, the electronic tag label enters the identification range of the reader, and the data read by the reader is fed back to the vehicle-mounted terminal. After processing, the vehicle-mounted terminal sends the data to the background database to complete the "carriage task" of the frame.
After the frame completes the "boarding task", the RFID reader can, according to system requirements, send the tag label information it has read to the vehicle-mounted terminal at intervals of a period of time to update the working status of the frame in real time. After the frame completes the task, it will be transferred away, and the RFID tag label on the frame will leave the reading range of the RFID reader. At this time, the RFID reader cannot detect the existence of the electronic tag label, and the vehicle-mounted terminal cannot receive the tag label information returned by the reader, so as to determine that the frame has completed the "getting off" operation. A complete work cycle of the frame ends, and the system updates and saves this information in real time to achieve the purpose of real-time supervision of the frame.
