Application case highlights
Different models and different components have different shelves for circulation. The application system solves the problems of a wide variety of shelves and different structures in the stamping shop, and realizes standardization of shelf label installation, standardization of collection equipment deployment, and standardization of operating procedures. Management objectives, on the basis of not changing the original operation process, to achieve the seamless integration of RFID technology;
Due to its own business characteristics and unique process flow, the logistics tracking system based on RFID technology does not have more application cases for reference and reference in the stamping workshop. The project overcomes these problems during implementation and satisfies the application requirements of this project. , Provides a good reference meaning for the same type of RFID applications;
The manufacturing system puts forward demanding requirements for the reliability of information technology. The recognition rate of more than 95% that RFID has always guaranteed is unacceptable. Ford’s press shop logistics tracking system has located 99.99% of RFID during the project approval stage. Recognition rate, and always use this as the criterion during the entire project implementation stage. Finally, through comprehensive technologies such as hardware selection, scheme design, software architecture, and system redundancy, it reached a recognition rate of nearly 100% once it was launched, and the integration method was obtained. And the user’s unanimous approval.
Case Introduction
Through the actual demand investigation in the stamping workshop, the construction of the logistics tracking system based on RFID technology in the stamping workshop mainly includes offline subsystem, inbound subsystem, and outbound subsystem according to functions. The system network topology is shown in the following figure.
Offline system
The off-line station fills the rack with the stamped parts, starts the turntable to rotate to the operable end of the forklift, and after the forklift picks up the rack of the equipment parts, it will exit the storage operation. During the exit process, the RFID electronic tag will enter the readable area of the offline station collection point, the reader will read the RFID electronic tag information on the shelf and transmit the information to the back-end system, and the back-end system will complete the batch The binding of stamping parts and chip information completes the establishment of basic data.
Access system
The forklift performs the in and out of the warehouse. When passing the warehouse gate, the RFID reader reads the electronic chip information of all the shelves on the forklift and uploads it to the back-end system. The back-end system obtains the bound part information according to the electronic tag information , And complete the corresponding material in and out process, and update the inventory in real time.
inventory
Use RFID handheld devices to download real-time inventory information of the warehouse by area. The staff will hold the handheld devices and pass through the logistics channels in the warehouse in turn, and check the information on the shelves on both sides to complete the verification and inspection of statistical data and actual inventory data.
