Product Details
DCS (Distributed Control System, Distributed Control System) is a distributed computer control system widely used in industrial process control. The following is a detailed introduction to the DCS system:
Basic Definition of 1.
DCS is the abbreviation of distributed control system, which is also called distributed control system in the domestic automatic control industry. It is a new type of computer control system relative to the centralized control system, which integrates computer, communication, display and control technology such as 4C, and its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration and convenient configuration.
2. development process
DCS system has been developed since the 1960 s and has experienced many stages of technological evolution. With the continuous development and improvement of computer, communication, control and CRT technology, DCS system has gradually matured and developed towards diversification, networking, openness and integrated management. At present, DCS has become the mainstream system of industrial process control.
3. main features
1. Decentralized control: DCS system uses decentralized control to distribute the control functions to each control unit, which improves the reliability and flexibility of the system.
2. Centralized operation: Centralized monitoring and control of the production process through the operation station, which is convenient for operators to control the overall situation.
3. Hierarchical management: DCS system adopts multi-layer hierarchical structure, which is convenient for hierarchical management and maintenance of the system.
4. Flexible configuration: The system can be flexibly configured and expanded according to actual needs to meet production processes of different scales and control requirements.
5. Convenient configuration: The software and hardware configuration of the system can be easily realized through the configuration software to meet different control strategies and application requirements.
