DCS是分布式控制系統(tǒng)的英文縮寫(Distributed Control System)，在國內(nèi)自控行業(yè)又稱之為集散控制系統(tǒng)。杭州先略發(fā)布的《DCS控制系統(tǒng)市場現(xiàn)狀分析及行業(yè)前景預(yù)測報告》研究顯示：是相對于集中式控制系統(tǒng)而言的一種新型計算機控制系統(tǒng)，它是在集中式控制系統(tǒng)的基礎(chǔ)上發(fā)展、演變而來的。DCS采用控制分散、操作和管理集中的基本設(shè)計思想，采用多層分級、合作自治的結(jié)構(gòu)形式。是以微機處理器為基礎(chǔ)，繼承單元組合儀表及計算機系統(tǒng)的優(yōu)點,充分利用控制技術(shù)、計算機技術(shù)、通信技術(shù)、圖像顯示技術(shù)(即4C技術(shù))的應(yīng)用成果，集中了連續(xù)控制、批量控制、順序邏輯控制和數(shù)據(jù)采集功能的計算機綜合控制系統(tǒng)。其主要特征是它的集中管理和分散控制。目前DCS在電力、冶金、石化等各行各業(yè)都獲得了極其廣泛的應(yīng)用。從結(jié)構(gòu)上劃分，DCS包括過程級、操作級和管理級。過程級主要由過程控制站、I/O單元和現(xiàn)場儀表組成，系統(tǒng)控制功能的主要實施部分。操作級包括：操作員站和工程師站，完成系統(tǒng)的操作和組態(tài)。3BHB005243R0105管理級主要是指工廠管理信息系統(tǒng)(MIS系統(tǒng))，作為DCS更高層次的應(yīng)用，目前國內(nèi)行業(yè)應(yīng)用到這一層的系統(tǒng)不是太多。上世紀70年代，由于經(jīng)濟的迅速發(fā)展，生產(chǎn)裝置迅速向大型化方向發(fā)展，尤其是石油煉制、冶金、化工、建材、電力等行業(yè)，這些行業(yè)生產(chǎn)裝置的大型化能夠帶來明顯的好處，如生產(chǎn)效率提高、原料消耗減少、勞動力成本降低等。生產(chǎn)設(shè)施的大型化要求設(shè)備之間具有更好的協(xié)調(diào)性，而且停機將帶來更大的損失。因此用戶迫切希望能夠有一種產(chǎn)品或者系統(tǒng)能夠解決生產(chǎn)設(shè)施大型化和連續(xù)化所面臨的控制問題。與此同時，在20世紀70年代中期，大規(guī)模集成電路取得突破性的發(fā)展，8位微處理器得到了廣泛的運用，使自動化儀表工業(yè)發(fā)生巨大的變化，現(xiàn)代意義上的DCS也應(yīng)運而生，1975年Honeywell推出了個DCS產(chǎn)品。隨著造紙生產(chǎn)工藝和設(shè)備的不斷進步，國內(nèi)制漿造紙行業(yè)對控制系統(tǒng)的自動化要求也越來越高。

DCS is the English abbreviation of Distributed Control System (Distributed Control System), which is also called distributed control system in the domestic automatic control industry. The "DCS control system market status analysis and industry prospects forecast Report" released by Hangzhou first shows that it is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system. DCS adopts the basic design idea of decentralized control, centralized operation and management, and adopts the structure form of multi-level classification and cooperative autonomy. It is a computer integrated control system based on microcomputer processor, inheriting the advantages of unit combination instrument and computer system, making full use of the application results of control technology, computer technology, communication technology, image display technology (that is, 4C technology), and concentrating the functions of continuous control, batch control, sequential logic control and data acquisition. Its main feature is its centralized management and decentralized control. At present, DCS has been widely used in all walks of life such as electric power, metallurgy and petrochemical industry. In terms of structure, DCS includes process level, operation level and management level. The process level is mainly composed of process control station, I/O unit and field instrument, which is the main implementation part of the system control function. The operation level includes: operator station and engineer station to complete the operation and configuration of the system. 3BHB005243R0105 Management level mainly refers to the factory management information system (MIS system), as a higher level of DCS application, the current domestic industry applied to this layer of the system is not too much. In the 1970s, due to the rapid development of the economy, the production equipment rapidly developed in the direction of large-scale, especially in petroleum refining, metallurgy, chemical industry, building materials, power and other industries, the large-scale production equipment in these industries can bring obvious benefits, such as production efficiency improvement, raw material consumption reduction, labor cost reduction. The large scale of production facilities requires better coordination between equipment, and downtime will bring greater losses. Therefore, users are eager to have a product or system that can solve the control problems faced by large-scale and continuous production facilities. At the same time, in the mid-1970s, the breakthrough development of large-scale integrated circuits, 8-bit microprocessors have been widely used, so that the automation instrument industry has undergone great changes, the modern sense of DCS also emerged, Honeywell launched a DCS product in 1975. With the continuous progress of paper production process and equipment, the automation requirements of control system in domestic pulp and paper industry are also getting higher and higher.
