针对排放含有SO2工业废气对环境造成的污染问题,设计了一种采用双碱法尾气脱硫的控制和监测系统。该系统由西门子 WINCC 的上位机监控系统和西门子 S7-300 PLC的下位机控制站组成。上位机部分利用组态软件WINCC设计,实现了人机交互的实时监控；下位机部分利用PLC编程软件 SIEMATIC STEP 7,采用模块化的编程方法,使用梯形图及语句表编制程序,实现了对各个电机和电磁阀的控制、传感器数据的采集以及变频器的控制,并通过模糊PID算法将可监测到的数据传送至上位机。系统可对整个脱硫过程进行显示、集成控制和监测,并利用SQL Server 实现对数据库的管理、查询、共享以及报表的打印,提高了工业脱硫的可靠性和自动化水平。

A control and monitoring system fordual alkali FGD has been designed for adG dressing environment pollution caused by SO2 containing industrial waste gas?The system comG poses of upper WINCC and a lower control system using SIEMENS S7-300 PLC? The upper part is designed by WINCC and can realize realGtime monitoring of humanGcomputer interaction?And the PLC programmable software SIEMATIC STEP 7 is used in the lower computer?Based on modular programming method and realized by ladder diagram and sentence table language,the lower computer can collect data from sensors,control electrical motors,electromagnetic valves and frequency converters,and transmit the monitoring data to the upper computer by fuzzy PID Arithmetic?By use of this system,the whole FGD process can be monitored,displayed and unG der integrated control?Through SQL Server,it can realize the management,query and share of the database,as well as printing of report forms,which can make the FGD process more reliable and raise the automation level.
