基于通用版MCGS与西门子系列PLC的电动机控制系统

Motor Control System Based on Universal MCGS and Siemens Series PLC

本项目是两台电动机的转速控制系统。在上位机中,用MCGS软件建立组态界面,搭建电动机控制系统的整体模型,能够完整显示整个调速过程及各类仪表和参数。核心控制器采用西门子S7-1200 PLC可编程控制器,实现两台电动机的起动停止、顺序控制、转速调整及故障报警、自动保护等功能。本项目通过以太网,将PLC与上位机MCGS搭建的组态界面进行通信连接,能够实现在上位机MCGS界面中,实时显示当前转速,修改手动自动调速方式,调节期望转速,设定顺控延时时间,PID参数等,具备一旦发生故障或超出转速正常运行范围自动报警等功能。

This project is aimed at the speed control system of two motors.In the upper computer,MCGS software is used to establish the configuration interface and build the overall model of the motor control system,which can completely display the whole speed regulation process,as well as various instruments and parameters.The core controller adopts Siemens S7-1200 PLC programmable controller to realize the start and stop,sequence control,speed adjustment,fault alarm,automatic protection and other functions of the two motors.The project communicates and connects the PLC with the MCGS configuration interface built by the upper computer through Ethernet,which can display the current speed in real time in the upper computer MCGS interface,modify the manual or automatic speed regulation mode,adjust the expected speed,set the sequence control delay time,PID parameters,etc.The system has the functions of automatic alarm in case of failure or exceeding the normal operation range of speed.
