Abstract:In order to solve existing problems of the traditional stamping production line, i.e. lower automation degree, lower efficiency and higher energy consumption, the design and development of field network configuration and distributed monitoring system for full automatic stamping production line were presented. This system was composed of several sets of precision stamping machines in connection, and an industrial robot was driven by high speed servo motor to implement materials palleting, feeding and automatic sequencing in work shifts. Synchronization, coordination and monitoring of movements between precision stamping machnes and industrial robot by field bus control to implement full automation of the stamping producton line. The system was applied of doublelayer industrial network design so that the realtime data communication based on underlying Cclink field bus guaranteed a rapid and reliable data transmission to implement distributed data sampling and monitoring, while the upper layer TCP/IP networking realized the large quantities of data transmission to facilitate remote monitoring, system integration and unified information management. The testing results show that the monitoring system is able not only to have functions of to capture, to display and to store machining data on the stamping production line in real time, but also to inquire a historical data on the machining process, to monitor and manage the process data and to give prewarning on possible failure in fault dignosis.
