中文摘要:本课题是基于西门子PLC的污水处理厂监控系统的设计。根据污水处理厂的特点，本控制系统采用目前国内外普遍应用的基于PLC的二级分布式集散控制系统。控制系统由设在综合房的中央控制室控制站和分布在现场3个PLC控制站组成，现场控制站由3套西门子PLC组成，通过PROFIBUS总线相互通信。本次设计主要完成对现场流程进行控制以及实现对整个系统的远程监控，通过现场PLC对各种电气设备的进行控制，通过变频器对提升泵的变频控制，利用wincc组态网实现对整个污水处理流程的监控。

Design and Implementation the Control System of Sewage Treatment Plant Based on PLC

Abstract:This topic is based on Siemens PLC's sewage treatment plant monitoring system design. According to the characteristics of sewage treatment plant, the control system uses the current domestic and universal application of two distributed based on PLC distributed control system. Control system consists of integrated housing in the central control room control station and distributed at the site 3 PLC control station, site controller composed by three sets of Siemens PLC, communicate with each other via PROFIBUS. The design process was completed for the on-site control and the realization of the entire system for remote monitoring through a variety of on-site PLC electrical equipment to be controlled through the drive to enhance the pump frequency control, use wincc configuration of the entire sewage network process flow monitoring.
