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。
