DCS control system generally refers to distributed control system, which is a new generation of instrument control system based on microprocessor and adopts the design principles of decentralized control function, centralized display and operation, taking into account division, autonomy and comprehensive coordination. Distributed control system is abbreviated as DCS, which can also be directly translated as "distributed control system" or "distributed computer control system".
It adopts the basic design idea of decentralized control, centralized operation and management, and adopts the structural form of multi-layer classification, cooperation and autonomy. Its main feature is its centralized management and decentralized control. At present, DCs has been widely used in electric power, metallurgy, petrochemical and other industries. （dcsKongZhiJiTongYouNaXieAnJia）
