PLC在污水泵站群远程控制系统中的应用

Application of PLC at Remote Sewage Pumping Stations

针对某排水公司污水泵站群的工艺和控制要求,设计了基于虚拟专用网交换数据的四层集散控制系统结构,阐述了以美国A-B公司的PLC为核心的系统硬件,同时详细地介绍了整个PLC控制软件的设计思路和流程.上位监控采用了INTOUCH软件,配以现场图像监控系统,在监控中心设置了大屏幕显示系统,在各个控制柜配置触摸屏控制系统.

A four-level distributed control system（DCS） is devised based on virtual private data exchanging network（VPN） according to the design techniques of sewage pumping stations for a Pumping Company.It gives a detailed statement on the components of the system hardware,especially on PLC produced by A-B Company,the U.S.A.The design of software is distributed,taking INTOUCH as monitoring system with DLP system and image-monitoring system.And touch panel is disposed on every PLC control cubicle.
