集散控制系統(tǒng)（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(chǎn)過程控制系統(tǒng)。隨著計算機和網(wǎng)絡技術的飛速發(fā)展，產(chǎn)生了一種新型的控制系統(tǒng)———現(xiàn)場總線控制系統(tǒng)（Fieldbus Control System－FCS）。但國內(nèi)生產(chǎn)企業(yè)的情況是：大多數(shù)企業(yè)還處于模擬儀表和人工控制的階段，采用DCS控制系統(tǒng)的企業(yè)仍是少數(shù)。由于DCS應用廣泛、技術成熟，在現(xiàn)有的技術條件和市場條件下，F(xiàn)CS還不能完全取代DCS，而且目前現(xiàn)場總線設備和系統(tǒng)還十分昂貴。因此，除了新建企業(yè)外，國內(nèi)企業(yè)在較長時間不可能全面采用現(xiàn)場總線技術，而必須走逐步發(fā)展、過渡的道路。 ??我們在上海石化股份公司環(huán)保部水質凈化廠監(jiān)控系統(tǒng)的改造項目中，對3個生產(chǎn)單元已有的DCS和PLC進行改造，增加通信功能，實現(xiàn)總調度室對各生產(chǎn)裝置的集中監(jiān)控。 2?系統(tǒng)改造方案?? 根據(jù)水質凈化廠各生產(chǎn)單元的功能和建設階段，分為廠外調節(jié)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(chǎn)單元。另外，在廠部設有總調度室，但是總調度室的監(jiān)控水平較為落后，改造之前基本上不能對各個生產(chǎn)單元進行監(jiān)控。為了適應生產(chǎn)需要，提高生產(chǎn)效率，改善操作條件，加強監(jiān)控手段，確保各生產(chǎn)裝置的正常運行，急需對各生產(chǎn)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(jiān)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(xiàn)場監(jiān)控系統(tǒng)的改造 ??現(xiàn)場監(jiān)控系統(tǒng)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(tǒng)結構見圖2—1）： ??四期污水處理生產(chǎn)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(shù)據(jù)高速通道）實現(xiàn)數(shù)據(jù)共享。在原有的現(xiàn)場控制計算機上分別增加以太網(wǎng)卡，通過以太網(wǎng)將實時數(shù)據(jù)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(tǒng)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(xiàn)場操作站，用點對點方法連接，使PLC的數(shù)據(jù)通過現(xiàn)場操作站送到以太網(wǎng)上，與總調度室監(jiān)控計算機通信。但RS－232傳輸速率只有9600bps，操作站僅對現(xiàn)場起到監(jiān)視作用。
