介绍了一种基于Wonderware的InTouch组态软件、Rockwell ControlLogix1756-L61冗余控制器和ControlNet、Profibus-DP现场总线组成的污水处理网络化控制系统(NCS);根据污水处理的工艺流程设计了系统监控级、主站级和现场级的分布式冗余控制系统结构以及控制网络的形式;阐述了系统工作的基本原理和主要过程,并对各控制层之间的垂直通讯进行了讨论.该系统自动化程度和可靠性都有较大的提高,现场实现了污水厂的全自动控制,实际运行效果显著.“,”A wastewater treatment networked control system based on the Wonderware InTouch,Rockwell ControlLogix 1756-L61Controller,ControlNet,Profibus-DP is presented. According to the process,the structure of the redundant distributed control system and the system control network of the management level,cell level and field level are designed. The hardware,software and some features of the system portion are introduced. The system working principles and process are described. The vertical communication between levels is discussed. This system implements the whole automatic control,with a good outcome.
