DCS是分布式控制系统的英文缩写(Distributed Control System)，在国内自控行业又称之为集散控制系统。杭州先略发布的《DCS控制系统市场现状分析及行业前景预测报告》研究显示：是相对于集中式控制系统而言的一种新型计算机控制系统，它是在集中式控制系统的基础上发展、演变而来的。DCS采用控制分散、操作和管理集中的基本设计思想，采用多层分级、合作自治的结构形式。是以微机处理器为基础，继承单元组合仪表及计算机系统的优点,充分利用控制技术、计算机技术、通信技术、图像显示技术(即4C技术)的应用成果，集中了连续控制、批量控制、顺序逻辑控制和数据采集功能的计算机综合控制系统。其主要特征是它的集中管理和分散控制。目前DCS在电力、冶金、石化等各行各业都获得了极其广泛的应用。从结构上划分，DCS包括过程级、操作级和管理级。过程级主要由过程控制站、I/O单元和现场仪表组成，系统控制功能的主要实施部分。操作级包括：操作员站和工程师站，完成系统的操作和组态。3BHB005243R0105管理级主要是指工厂管理信息系统(MIS系统)，作为DCS更高层次的应用，目前国内行业应用到这一层的系统不是太多。上世纪70年代，由于经济的迅速发展，生产装置迅速向大型化方向发展，尤其是石油炼制、冶金、化工、建材、电力等行业，这些行业生产装置的大型化能够带来明显的好处，如生产效率提高、原料消耗减少、劳动力成本降低等。生产设施的大型化要求设备之间具有更好的协调性，而且停机将带来更大的损失。因此用户迫切希望能够有一种产品或者系统能够解决生产设施大型化和连续化所面临的控制问题。与此同时，在20世纪70年代中期，大规模集成电路取得突破性的发展，8位微处理器得到了广泛的运用，使自动化仪表工业发生巨大的变化，现代意义上的DCS也应运而生，1975年Honeywell推出了个DCS产品。随着造纸生产工艺和设备的不断进步，国内制浆造纸行业对控制系统的自动化要求也越来越高。

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.
