基于PROFIBUS现场总线的伞齿轮精密热模锻生产线控制系统

The control system of precise hot-mould-forging production line of bevel gears based on PROFIBUS fieldbus

本文介绍了伞齿轮精密热模锻生产线自动控制系统的构成、工作原理及控制策略 ,中央控制系统采用Profibus -DP总线与现场设备通讯 ,以满足控制实时性的要求。概述了SIEMENSSIMATICSTEP7编程特点及主机控制程序流程图。

This paper introduces the constitution,working principle and control tactics of the automatic control system in the precise hot-mould-forging production line of bevel gears.The centre control system is designed to communicate with the spot equipment by means of Profibus-DP fieldbus to meet the needs of real time control.And also in this paper is presented the programming properties of SIEMENS SIMATIC STEP7 and programme flow chart of host station PLC.
