基于MCGS的风机变频监控系统设计

摘要

主要讨论了风机变频监控系统的硬件组成、工作原理、PLC程序设计,MCGS组态中数据库的建立、PLC的连接、监控界面的设计等,系统最后经调试和PID参数整定后投入运行.该系统解决了PLC控制系统无法显示的缺点,具有调节及时、调节速度快、没有余差、监控方便等特点,使企业的管理更为方便快捷,提高了企业的自动控制水平.%Focused on the fan variable frequency monitoring system, including its hardware components, working principle, PLC programming, the establishment of the database in MCGS configuration, the connection to the PLC, monitoring interface and so on. The system put into operation after debugging and adjusting the PID parameters. The system solved the problems that the PLC control system can not solve. It could start adjustment timely, rapidly with no error and can easy to monitor. It made enterprise management more convenient and efficient improve the level of automatic control.
