5X00226G02 實(shí)現(xiàn)強(qiáng)大的顯示功能、報(bào)警功能、操作功能、報(bào)表打印功能、組態(tài)和編程功能等

分散式控制系統(tǒng)（Distributed Control System，簡稱DCS）是一種基于微處理器的控制系統(tǒng)，其設(shè)計(jì)原則是將控制功能分散到各個(gè)子系統(tǒng)中，而操作和管理則集中在中央控制室。這種系統(tǒng)采用多層分級(jí)、合作自治的結(jié)構(gòu)形式，其主要特征是集中管理和分散控制。

在DCS中，5X00226G02過程控制級(jí)具體實(shí)現(xiàn)了信號(hào)的輸入、變換、運(yùn)算和輸出等分散控制功能。過程控制級(jí)包括各種控制裝置，如過程控制單元、現(xiàn)場控制站、過程接口單元等，它們的結(jié)構(gòu)形式大致相同，可以統(tǒng)稱為現(xiàn)場控制單元（FCU）。DCS的硬件和軟件都是按照模塊化結(jié)構(gòu)設(shè)計(jì)的，系統(tǒng)的開發(fā)過程就是將提供的各種基本模塊根據(jù)實(shí)際需要組合成一個(gè)完整的系統(tǒng)，這個(gè)過程稱為系統(tǒng)的組態(tài)。

操作站用于顯示并記錄來自各控制單元的過程數(shù)據(jù)，是人與生產(chǎn)過程信息交互的操作接口。典型的操作站包括主機(jī)系統(tǒng)、顯示設(shè)備、鍵盤輸入設(shè)備、信息存儲(chǔ)設(shè)備和打印輸出設(shè)備等，主要實(shí)現(xiàn)強(qiáng)大的顯示功能、報(bào)警功能、操作功能、報(bào)表打印功能、組態(tài)和編程功能等。此外，DCS操作站還分為操作員站和工程師站。

分散控制是指系統(tǒng)中的控制部分表現(xiàn)為若干個(gè)分散的、有一定相對獨(dú)立性的子控制機(jī)構(gòu)，這些機(jī)構(gòu)在各自的范圍內(nèi)各司其責(zé)，各行其是，互不干涉，各自完成自己的目標(biāo)。5X00226G02分散控制的優(yōu)點(diǎn)是針對性強(qiáng)，信息傳遞效率高，系統(tǒng)適應(yīng)性強(qiáng)，特別適用于系統(tǒng)組織較松散的部門，如城市各交叉路口的交通管理、企業(yè)集團(tuán)的一些外圍企業(yè)等。

DCS廣泛應(yīng)用于電力、冶金、石化等各行各業(yè)的生產(chǎn)過程控制。5X00226G02是以計(jì)算機(jī)、通信和屏幕顯示技術(shù)為基礎(chǔ)，實(shí)現(xiàn)對生產(chǎn)過程的數(shù)據(jù)采集、控制和保護(hù)功能，并實(shí)現(xiàn)數(shù)據(jù)共享的多計(jì)算機(jī)監(jiān)控系統(tǒng)。

A Distributed Control System (DCS) is a microprocessor-based control system designed to decentralize control functions to various subsystems, while operations and management are centralized in a central control room. This kind of system adopts the structure form of multi-tiered, cooperative and autonomous, and its main characteristics are centralized management and decentralized control.

In DCS, the 5X00226G02 process control stage realizes the decentralized control functions of signal input, transformation, operation and output. The process control level includes various control devices, such as process control units, field control stations, process interface units, etc., whose structural forms are roughly the same and can be collectively referred to as field control units (FCU). DCS hardware and software are designed in accordance with the modular structure, the development process of the system is to provide a variety of basic modules according to actual needs combined into a complete system, this process is called the configuration of the system.

The operation station is used to display and record the process data from each control unit, and is the operation interface for people to interact with the production process information. Typical operating station includes host system, display device, keyboard input device, information storage device and print out device, etc., mainly to achieve powerful display function, alarm function, operation function, report printing function, configuration and programming function. In addition, DCS operating stations are also divided into operator stations and engineer stations.

Decentralized control means that the control part of the system is manifested as a number of decentralized and relatively independent sub-control institutions, which perform their own responsibilities within their own scope, act independently, do not interfere with each other, and accomplish their own goals. 5X00226G02 decentralized control has the advantages of strong pertinency, high information transmission efficiency, and strong system adaptability, which is especially suitable for departments with loose system organization, such as traffic management at urban intersections and some peripheral enterprises of enterprise groups.

DCS is widely used in power, metallurgy, petrochemical and other industries of production process control. 5X00226G02 is a multi-computer monitoring system based on computer, communication and screen display technology to achieve data acquisition, control and protection of the production process, and to achieve data sharing.
