RFID (Radio Frequency Identification) is a rapid identification technology that has developed rapidly in recent years. It obtains information through non-contact identification of identified objects. Compared with traditional barcode technology, it has the characteristics of large data capacity, non-contact identification, long storage time, anti-pollution, strong adaptation to harsh environments and others, so it is widely used in various industries.
In recent years, automobile manufacturers have spent a lot of their IT budgets on supply chain management systems in order to achieve a transparent and flexible supply chain. The application of RFID system in material and product tracking will have a positive impact on the automotive supply chain. By deploying the RFID system, the visual management of the supply chain process and the distributed control of the manufacturing process can be realized.
A typical RFID automatic identification system consists of the following parts: data carrier, read/write unit and interface module. The interface module is connected to PLC, PC and other control units by main line communication or string line communication.
Establish a unified central database in the enterprise's workshop as an information platform for the circulation of goods to facilitate overall standardized management. In the industrial link, RFID technology is used to assign an identification number (ID) to each work-in-progress component, which is the name of the component in the information network. Through RFID technology, the production situation and inventory situation are mapped to the information network and registered in the center database, and then transmitted to the information system (such as ERP, MRP), etc.
