The Automatic Control System of Transmission Equipment in SAWL Pipe Production Line

This paper introduced configuration and process flow of transmission equipment in SAWL pipe production line,and emphasized function,design framework and hardwares of transmission equipment automatic control system.According to theories of steel pipe stop and transition carriage working position recognition,it proposed design and realization modes of automatic control system software.This kind of automatic control system,adopting collecting and distributing control mode and distributed I/O control technology,has been applied into production line.The results indicated that it can optimize process flow,reduce labor intensity and increase production efficiency,as well as make production course more safety and stability.
