Application of RFID Tags in Cars

RFID (radio frequency identification) is a burgeoning rapid identification technology in recent years, which obtains data information through the non-contact recognition of recognized objects. Compared with the traditional bar code technology, it has the characteristics of large data capacity, non-contact identification, long storage time, pollution resistance and adaptability to the harsh environment. Therefore, it is widely used in various industries.


In recent years, automobile manufacturers have spent a lot of IT budget on their supply chain management systems, aiming to realize a transparent and flexible supply chain. In the tracking of materials and products, RFID technology will have a positive impact on the automotive supply chain. Through the deployment of RFID system, the visual management of the supply chain process and the distributed control of the manufacturing process can be realized.


The typical RFID automatic identification system consists of the following parts: data carrier, read/write unit, and interface module. The interface module is connected with PLC, PC, and other control units by bus or serial communication.


Design principles

A unified central database should be established in the workshop of the enterprise as an information platform for the circulation of goods, so as to facilitate the overall standardized management. In the industrial process, RFID inlay is used to assign an identification number (ID) to each part in the process, that is, the name of the part in the information network. Through RFID technology, the production status and inventory situation are mapped to the information network, registered in the field central database, and transmitted to the information system (such as ERP, MRP).
