Modern manufacturing enterprises integrate production scheduling, product tracking, quality control, equipment failure analysis, network reports and other management functions through a well-designed MES system on a unified platform. Using a unified database and network connection, they can provide workshop management information services for production department, quality inspection department, process department and logistics department at the same time. By emphasizing the overall optimization of manufacturing process, the system helps enterprises to implement complete closed-loop production and establish an integrated and real-time ERP / MES / SFC information system.

The traditional MES management system has a series of problems

1. In the production process, the information of each link is manually input, which is easy to make mistakes, so that the work steps can not be connected normally, and the production efficiency is affected.

2. In case of product quality problems, due to incomplete record data, it can not be traced back to the process and station where the quality problems occur.

3. The production department does not grasp the site information completely, which makes the semi-finished products easy to produce a large amount of inventory and affects the production and management of enterprises.

4. Managers can not directly understand the production status of the production line, can not adjust the operation plan according to the actual situation of production, and solve the actual problems in production.

After the application of RFID technology, the above problems can be solved: it can dynamically store the content of each process; Monitor and manage the production line to make the demand plan more timely and accurate; Reduce the waste of time and resources; It can track and locate the processing information of each process of tire, which improves the production quality and efficiency.

Data is the blood and foundation of MES system to realize the normal operation of workshop production management information. In front of us, we analyzed the data acquisition function of MES system and the application mode of production management in the information-based production management workshop. Today, the author will talk about how to realize the data acquisition of MES system. In terms of the development level of information technology in the industry, the MES system industry usually adopts RFID and MES integration technology to achieve real-time production data collection, so how to realize the integration of RFID and MES?

For the current RFID middleware architecture and MES system integration method, from the application level, including the edge layer, enterprise layer, application layer; From the physical structure, it can be divided into hardware layer, data acquisition layer, workflow management layer, service layer and legacy system layer; From the functional level that RFID and MES integration technology can achieve, including RFID edge server and RFID enterprise server, through the edge server directly connected with various terminal devices, control the RFID read-write device to work in accordance with the predetermined way, coordinate the application of different devices, and realize redundant data filtering and screening, and transfer the real and effective data to the background MES system; The enterprise server manages all edge servers, handles all kinds of RFID events and information exchange, manages real-time workflow, integrates with MES system effectively, and realizes the timely collection, analysis, integration and interaction of workshop production process data.

As a bridge between RFID hardware devices and MES system, RFID middleware is an integrated technology to achieve data acquisition and management between RFID and background MES system.
