Production line control system and its control method

Abstract

The invention discloses a production line control system and a control method thereof and relates to the technical field of control. The production line control system comprises a programmable logic controller (PLC) system and a main server. The PLC system comprises multiple work stations connected to the main server. The production line control system further comprises a radio frequency identification device (RFID) radio frequency read-write system. The RFID radio frequency read-write system comprises information reading points and RFID labels, wherein the information reading points are arranged on production lines, and multiple tool plates are further arranged on the production lines, and the RFID labels are written on the multiple tool plates. The information reading points read data information in the RFID labels on the tool plates and transfers the data information to the main server. Due to the fact that the production line control system enables the PLC system and the RFID radio frequency read-write system to be compatible, control of a production device and acquisition of the product data information are synchronously performed, information transmission between two sub-systems is achieved, and the purpose of common control of the production line is achieved.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a production line control system and a control method thereof. Background technique [0002] In industrial production, in order to maintain high-level and high-efficiency operation of equipment and production, we have to consider whether the production and distribution of materials and finished products on the production line are orderly and uniform, whether the on-site data is fed back and managed, and whether the fault information is Can be effectively communicated and resolved. With the improvement of technological level and the development of industrial control technology, the degree of automation in the production process is getting higher and higher, and the production line control system enables the production manager to remotely understand the production status and equipment operation status, which is convenient for management and control, and thus has been widely used ...

Problems solved by technology

The usual method of use is to add RFID tags to the product body, and write corresponding information in the corresponding process (similar to the barcode management system), read the information through RFID and feed it to MES, ERP, CRM, or IDM, etc. after processing, to establish a powerful The information data link provides real-time data information query function, realizes a higher level of quality control and various online measurements, and improves the convenience of production process control, but it is only used for high-precision information collection and identification, and cannot be effectively achieved. Realize the purpose of controlling production equipment according to the different production processes of products
