集散控制系統（Distributed Control System－DCS）集計算機技術、控制技術、通信技術、CRT技術于一體，廣泛應用于生產過程控制系統。隨著計算機和網絡技術的飛速發展，產生了一種新型的控制系統———現場總線控制系統（Fieldbus Control System－FCS）。但國內生產企業的情況是：大多數企業還處于模擬儀表和人工控制的階段，采用DCS控制系統的企業仍是少數。由于DCS應用廣泛、技術成熟，在現有的技術條件和市場條件下，FCS還不能完全取代DCS，而且目前現場總線設備和系統還十分昂貴。因此，除了新建企業外，國內企業在較長時間不可能全面采用現場總線技術，而必須走逐步發展、過渡的道路。 ??我們在上海石化股份公司環保部水質凈化廠監控系統的改造項目中，對3個生產單元已有的DCS和PLC進行改造，增加通信功能，實現總調度室對各生產裝置的集中監控。 2?系統改造方案?? 根據水質凈化廠各生產單元的功能和建設階段，分為廠外調節池、污水一段、氧化溝、四期污水處理、污泥脫水、污泥干化6個生產單元。另外，在廠部設有總調度室，但是總調度室的監控水平較為落后，改造之前基本上不能對各個生產單元進行監控。為了適應生產需要，提高生產效率，改善操作條件，加強監控手段，確保各生產裝置的正常運行，急需對各生產單元和總調度室進行技術和設備的更新改造，從而能在總調度室對各裝置進行監視管理，及時了解各裝置的運行情況，達到指揮及時和調度準確的目的。 2．1?現場監控系統的改造 ??現場監控系統的改造要充分利用原有儀表和設備，主要考慮可靠性和實時性。首先對自控程度較高的3個單元進行改造（系統結構見圖2—1）： ??四期污水處理生產單元控制設備配置了兩套ALLEN－BRADELY公司PLC設備。25塊開關量輸入信號卡，可采集384點信號；7塊開關量輸出信號卡，可輸出112點信號；3塊模擬量輸入信號卡，可采集24點信號。兩套AB—PLC通過DH＋（數據高速通道）實現數據共享。在原有的現場控制計算機上分別增加以太網卡，通過以太網將實時數據送到總調度室處理。??輸出192點信號；1塊模擬量輸入信號卡，可采集8點信號。系統運行采用遙控開關操作與全模擬流程盤顯示。在原有的Siemens S5－115UPLC上增加RS－232通訊模塊（CP524）和1臺現場操作站，用點對點方法連接，使PLC的數據通過現場操作站送到以太網上，與總調度室監控計算機通信。但RS－232傳輸速率只有9600bps，操作站僅對現場起到監視作用。Siemens 3VL9300-3MN00
