Research on the Flexible Manufacturing Information Management System based on Industry Ethernet: In recent years, CNC bending machine manufacturer Zhejiang Kingmazon machinery Co., Ltd. makes use of the advantage in the research of workstation of postdoctoral scientific research, actively carry out CNC bending machine industry research based on Industrial Ethernet flexible manufacturing information management system, the information management system by the central server, industrial computer and terminal operation, a serial port server, PLC and the process production equipment composition. The whole system can be divided into the control layer which is the core of the industrial field equipment, the monitoring layer and the management layer based on the central server as the core of the PLC as the core. The production equipment is controlled by PLC, and the information exchange between PLC and Ethernet is accomplished through the serial port. The industrial computer realizes the control of the whole production line. The central server realizes the management of the whole production line.

Research on the industry of the numerical control pipe bending machine is based on the information management system of the industry Ethernet. It can make the robot on the production line according to the established process and realize the automatic operation of the robot. Production system adopts the centralized control mode has the interlock protection function, namely a shutdown, will lead to automated assembly line chain stop, and according to the production status of the process, with the reverse start function. Centralized control in the process of chain protection mechanism, main research fault shutdown protection, fault alarm display mechanism, fault self-locking and unlocking and systems across the board state of para and across the board liaison signal intercom functions. Information management system combines sensor technology, automatic detection technology, communication technology, control theory and information theory, develop distributed measurement and centralized diagnosis camera and pipe quality monitoring system, realize production line dynamic scheduling, monitoring fault diagnosis, process control, quality management control, sensor fusion feedback and sound and light alarm. The research on the industry of the CNC pipe bending machine is based on the technology of the flexible manufacturing information management system, which will be very suitable for the industry 4 and 2025.
