摘要
结合PLC和WINCC的特点以及循环水自动加药系统的控制要求,介绍了S7-200系列PLC和WINCC组态软件应用于工业循环水水质在线监测的工艺设计与技术。作者分析了系统的组成及工艺控制要求,软硬件的配置和PID具体控制方案。该系统已投入实际运行,经实践证明,控制系统人机交互性好、可靠性高、抗干扰能力强,满足了现代工业循环水质监管的要求。
Combining the characteristics of PLC and WINCC and the actual control requirement of automatic reagentadding system of circulating water in the water factory,the PLC of SIMATIC S7-200 series and WINCC configuration software applied to the technologic design and implementing technology of online-monitor for the water quality of industrial circulating water is introduced. The system composition and the requirement of technical control are analyzed firstly, and ,then ,the configuration of hardware and software and control strategy are described concretely. This system has been put into operation in the water factory. It is proven that the man-machine interaction of the control system is good,its reliability is high,and the ability of anti-jamming is strong. It has satisfied the requirement of supervising the water quality of modern industrial circulating water.
