Abstract

The invention discloses a DCS control system which comprises a control station connected with a configuration monitoring software device and at least two DP main stations connected with the control station, the control station is a control station of a multi-task operating system and used for configuring a plurality of IEC tasks, and the DP main stations and the IEC tasks are in mapping association. The control station adopts a multi-task operation system, a plurality of IEC tasks can be configured at the same time, the DP main station and the IEC tasks are in mapping association, one IEC taskcan be associated with a plurality of DP main stations, but the same DP main station can only be associated with one IEC task, and as the support of the plurality of DP main stations can be realized,the faster operation speed can be realized; the whole DCS control system is suitable for being deployed in a large-scale complex scene, the deployment number of control stations is reduced, the utilization efficiency of a DP main station is improved, and the DCS control system is low in deployment cost, high in integration degree, good in reliability and flexible in configuration.

Description

technical field [0001] The invention relates to the technical field of DCS control, in particular to a DCS control system. Background technique [0002] The Distributed Control System is referred to as DCS, and it can also be literally translated as "Distributed Control System" or "Distributed Computer Control System". It adopts the basic design idea of ​​decentralized control, centralized operation and management, adopts a multi-layer hierarchical, cooperative and autonomous structural form, and its main feature is its centralized management and decentralized control. At present, DCS has been widely used in various industries such as electric power, metallurgy, petrochemical and so on. [0003] DCS usually adopts a hierarchical structure, each level is composed of several subsystems, and each subsystem achieves some specific limited goals, forming a pyramid structure. [0004] Reliability is the life of DCS development. There are three main measures to ensure the high rel...
