系統硬件布置如下：前置機1使用FGD-DCS系統操作員站；后置機使用環保局數據采集工控機，安裝在脫硫除塵控制室。網閘設備使用1套獨立的單向物理隔離網閘（需要由電力部、部安全認證的產品）；
三紫金橋數據平臺介紹
紫金橋軟件針對新華DCS UDP方式單獨開發了接收數據的程序，采用被動監聽端口和接受數據的方式采集數據，這樣不用在新華DCS系統上安裝任何軟件，確保DCS的安全，同時由于網閘的隔離作用，紫金橋軟件是不會向DCS系統內發送任何數據，從而避免人為因素或計算機病毒對新華DCS系統的影響。
首先在新華DCS一側信息網MMI站和后置計算機（環保局工控機）之間加上網閘，只允許新華DCS數據單向傳輸給后置計算機；然后在MMI站上配置Asdpu.exe程序，使其以UDP方式周期向MIS網廣播所需的數據報文。在后置計算機上安裝紫金橋UDP數據接收程序來被動接收新華DCS實時數據，同時啟動本地后置機上的紫金橋實時數據庫；紫金橋實時數據庫OPCServer即可對環保局提供新華DCS實時數據。如圖2所示

四項目實施后的效果
從DCS側信息數據包可以通過網閘傳輸到管理網側。從管理網側到DCS側不能通過任何數據包；數據吞吐量大于每分鐘1萬點信息數據包。在后置機上提供工業標準通訊接口OPC Server，與環保數據采集通訊成功，將環保部門所需數據按其要求進行傳送、交換。
