What is DCS control system?

DCS is a distributed control system, which is a multi-level computer system composed of process control level and process monitoring level. It is linked by communication network and integrates 4C technologies such as computer, communication, display and control.

Usually, the hierarchical structure is adopted, and each layer is composed of several subsystems, and each subsystem achieves several specific limited goals, forming a pyramid structure. Its main features are centralized management and decentralized control.

Extended data

The configuration of DCS control system is flexible and convenient, and its specific features are as follows:

1, high reliability

The DCS control system distributes the control function on each computer, and each computer undertakes a separate system task. The failure of any computer module will not affect other computer systems.

2, convenient maintenance

The DCS control system has advanced hardware equipment and can run in various harsh working environments. The system has the functions of automatic identification and fault diagnosis, which is convenient for operators to maintain and deal with.

3, the operation is convenient

This paper briefly introduces the operation interface of DCS control system. Operators can monitor the production operation of production equipment and even the whole plant through simple mouse and keyboard operation, and adjust the operation data according to production requirements.

4, the configuration is flexible and convenient

Powerful configurable function simplifies the use and saves a lot of time. Whether it is a simple single-loop control or a more complex control loop, DCS can provide support for users. At the same time, it provides users with the support ability to independently develop special advanced control algorithms.

5. Strong data processing ability

It can convert and collect as many as 3-65438+100000 bits on site, and display, store and control them in real time through processor operation.

6. Open architecture

The DCS control system adopts standardized and modular design, which can provide multi-layer open data interface.
