D202275 分布式控制系统的主要特点包括集中管理和分散控制

分布式控制系统（Distributed Control System，简称DCS）也称为集散控制系统，是对生产过程进行集中管理和分散控制的计算机控制系统。D202275融合了计算机技术、网络技术、通信技术和自动控制技术，是随着现代大型工业生产自动化水平的不断提高和过程控制要求日益复杂应运而生的综合控制系统。

分布式控制系统的主要特点包括集中管理和分散控制。系统采用分散控制和集中管理的设计思想，分而自治和综合协调的设计原则，具有层次化的体系结构。它主要由过程控制单元（PCU）、数据采集装置（DAU）、CRT操作站、监控计算机和数据高速公路（HW）五部分组成。在分布式控制系统中，各子系统间有密切的联系，并能进行信息交换，系统对其总体目标和任务可以进行综合协调与分配。

此外，分布式控制系统还广泛应用于电力、冶金、石化等各行各业。D202275采用控制分散、操作和管理集中的基本设计思想，采用多层分级、合作自治的结构形式。各回路之间和上下级之间通过高速数据通道交换信息，具有数据获取、直接数字控制、人机交互以及监控和管理等功能。

Distributed Control System (DCS), also known as Distributed Control System, is a computer control system for centralized management and decentralized control of the production process. D202275 integrates computer technology, network technology, communication technology and automatic control technology, which is an integrated control system with the continuous improvement of the automation level of modern large-scale industrial production and the increasingly complex process control requirements.

The main characteristics of distributed control system include centralized management and decentralized control. The system adopts the design idea of decentralized control and centralized management, the design principle of division and autonomy and comprehensive coordination, and has a hierarchical architecture. It mainly consists of five parts: process control unit (PCU), data acquisition device (DAU), CRT operating station, monitoring computer and data highway (HW). In the distributed control system, the subsystems have close relations and can exchange information, and the system can coordinate and distribute its overall goals and tasks.

In addition, the distributed control system is also widely used in power, metallurgy, petrochemical and other industries. D202275 adopts the basic design idea of decentralized control, centralized operation and management, and adopts the structure form of multi-layer classification and cooperation autonomy. Information is exchanged between each loop and between the upper and lower levels through high-speed data channel, which has the functions of data acquisition, direct digital control, man-machine interaction, monitoring and management.
