摘　　要：针对热电厂循环水的处理问题,设计热电厂循环水自动加药计算机监控系统。本系统采用IPC和PLC组成的上下位机结构,上位机采用组态王6.52组态软件,主要承担监测和管理任务,实现工艺流程显示、人机交互界面、数据存储及报表等功能。下位机使用梯形图语言编程,进行实时数据采集和各种药品的投加控制。经过现场实际运行证明,该系统结构简单、操作方便、控制算法简单实用,取得了良好的经济效益。Aiming at the problem of thermal power plant for recycling water treatment, desings water cycle thermal power plant automatic-computer monitoring system. The system is composed of the PLC and IPC crew structure from top to bottom, King View 6.52 configuration software, is mainly responsible for monitoring and managing tasks and achieve process, humancomputer interface, data storage and statements, and other functions. The crew uses ladder language programming, real-time data acquisition and various drug dosage control. After the actual operation of the site proves that the system is simple, convenient operation, simple control algorithms, and achieves good economic benefits.
