The RFID logistics tracking system was successfully applied in a stamping workshop

Application case highlights

Different car models and different component parts require different shelves for circulation. The application system solves the problem of a wide variety of shelves with different structures in the stamping workshop, and realizes the standardization of shelf label installation, standardization of collection equipment deployment, and standardization of work processes. The management goal is to achieve the seamless integration of RFID technology without changing the original operation process;

Due to its own business characteristics and unique process flow, the stamping workshop does not have more application cases for reference and reference for the logistics tracking system based on RFID technology. The project will overcome these problems during implementation and meet the application needs of this project. , providing a good reference for similar types of RFID applications;

The production and manufacturing system puts forward almost stringent requirements for the reliability of information technology. The recognition rate of more than 95% that RFID has always guaranteed is unacceptable. The Ford stamping workshop logistics tracking system positioned RFID at 99.99% during the project establishment stage. Recognition rate, and this was always used as a criterion throughout the project implementation phase. Finally, through comprehensive technologies such as hardware selection, solution design, software architecture, and system redundancy, a recognition rate of nearly 100% was achieved as soon as it went online, and the integration method was obtained. and the unanimous approval of the user.

Case introduction

Through the actual demand survey in the stamping workshop, the construction of the stamping workshop logistics tracking system based on RFID technology mainly includes the offline subsystem, the warehousing subsystem, and the warehousing subsystem according to the functional division. The system network topology is shown in the figure below.

Offline system

The off-line station fills the shelves with stamped parts and starts the turntable to rotate to the operable end of the forklift. After the forklift picks up the shelves equipped with parts, it will exit for warehousing operations. During the exit process, the RFID electronic tag will enter the readable area of the offline work station collection point. The reader reads the RFID electronic tag information on the shelf and transmits the information to the backend system. The backend system will complete the batch. The binding of stamping parts and chip information completes the establishment of basic data.

Inbound and outbound system

The forklift carries out the entry and exit of the shelves. When passing by the warehouse gate, the RFID Reader reads the electronic chip information of all the shelves on the forklift and uploads it to the backend system. The backend system obtains the bound parts information based on the electronic tag information. , and complete the entry and exit process of corresponding materials, 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 device and pass through the logistics channels in the warehouse in sequence, and inventory the shelf information on both sides to complete the verification of statistical data and actual inventory data.
