摘　　要：由于缺乏有效监管手段,目前脱硫设施实际投运情况不理想。设计了一套B/S架构的烟气脱硫设施运行及脱硫电价实时监控系统,分为数据采集、数据通讯、数据处理及发布3个子系统。选择能全面反映脱硫设施运行状况的28个信号,采用"共享-分流"信号防伪采集技术进行采集,通过电力系统内载波电话拨号与无线GPRS两种通讯方式相互竞争、互为备用来实现可靠通讯,并经过软件防伪判别模块和统计运算后以WEB形式发布。数据以5m in的间隔实时刷新,且每小时更新脱硫投入率、脱硫电价款等报表数据。In the absence of an effective means of monitoring the actual FGD usage is low.A real-time monitoring system for operation status of FGD and electric price of desulfurization based on B/S is designed,which is composed of data acquisition,data communications,data processing and dissemination.In this system,28 signals are selected to reveal the FGD operation status,and an anti-counterfeiting data acquisition technology named ＂shared-diversion＂ is proposed.A reliable back-up communications is achieved by competition between power line carrier communication and GPRS wireless communication.Data is issued by WEB after throughing anti-counterfeiting and statistical software modules,refreshed at 5min intervals,and statistical data was updated hourly such as FGD usage,electric price of desulfurization,etc.
