5X00226G02 实现强大的显示功能、报警功能、操作功能、报表打印功能、组态和编程功能等

分散式控制系统（Distributed Control System，简称DCS）是一种基于微处理器的控制系统，其设计原则是将控制功能分散到各个子系统中，而操作和管理则集中在中央控制室。这种系统采用多层分级、合作自治的结构形式，其主要特征是集中管理和分散控制。

在DCS中，5X00226G02过程控制级具体实现了信号的输入、变换、运算和输出等分散控制功能。过程控制级包括各种控制装置，如过程控制单元、现场控制站、过程接口单元等，它们的结构形式大致相同，可以统称为现场控制单元（FCU）。DCS的硬件和软件都是按照模块化结构设计的，系统的开发过程就是将提供的各种基本模块根据实际需要组合成一个完整的系统，这个过程称为系统的组态。

操作站用于显示并记录来自各控制单元的过程数据，是人与生产过程信息交互的操作接口。典型的操作站包括主机系统、显示设备、键盘输入设备、信息存储设备和打印输出设备等，主要实现强大的显示功能、报警功能、操作功能、报表打印功能、组态和编程功能等。此外，DCS操作站还分为操作员站和工程师站。

分散控制是指系统中的控制部分表现为若干个分散的、有一定相对独立性的子控制机构，这些机构在各自的范围内各司其责，各行其是，互不干涉，各自完成自己的目标。5X00226G02分散控制的优点是针对性强，信息传递效率高，系统适应性强，特别适用于系统组织较松散的部门，如城市各交叉路口的交通管理、企业集团的一些外围企业等。

DCS广泛应用于电力、冶金、石化等各行各业的生产过程控制。5X00226G02是以计算机、通信和屏幕显示技术为基础，实现对生产过程的数据采集、控制和保护功能，并实现数据共享的多计算机监控系统。

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.
