1. Generally speaking, DCS refers to distributed control system.
2. The distributed control system is a new generation of instrument control system based on microprocessor, which adopts the design principles of decentralized control function, centralized display and operation, independent division and comprehensive coordination. The distributed control system is referred to as DCS, which can also be directly translated as "distributed control system" or "distributed computer control system".
3. It adopts the basic design idea of decentralized control and centralized operation management, and adopts the structural form of multi-level classification, cooperation and autonomy. Its main characteristics are centralized management and decentralized control. At present, DCS has been widely used in power, metallurgy, petrochemical and other industries.
