MA-0185-100 控制处理在系统中节点周围的分布

分布式控制系统（Distributed Control System，简称DCS）也称为集散控制系统，是一种计算机化的控制系统，MA-0185-100用于对过程或工厂进行集中管理和分散控制。该系统主要特点包括各子系统间的密切联系和信息交换，以及系统对其总体目标和任务的综合协调与分配。

DCS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。此外，DCS还采用了分散控制和集中管理的设计思想，以及多层分级、合作自治的结构形式。其关键属性是可靠性，控制处理在系统中节点周围的分布，减轻了单个处理器的故障影响。

在功能上、逻辑上、物理上以及地理位置上，DCS都是分散的。同时，该系统还融合了计算机技术、网络技术、通信技术和自动控制技术，MA-0185-100是一种把危险分散、控制集中优化的新型控制系统。DCS在电力、冶金、石化等各行各业都获得了极其广泛的应用。

Distributed Control System (DCS), also known as Distributed Control System, is a computerized control system, MA-0185-100 used for centralized management and decentralized control of processes or plants. The main features of the system include the close connection and information exchange among the subsystems, as well as the integrated coordination and allocation of the system’s overall objectives and tasks.

DCS consists of five parts: process control unit (PCU), data acquisition device (DAU), CRT operating station, monitoring computer and data highway (HW). In addition, DCS also adopts the design idea of decentralized control and centralized management, as well as the structure form of multi-level classification and cooperative autonomy. Its key attribute is reliability, which controls the distribution of processing around nodes in the system, mitigating the impact of failure of a single processor.

Functionally, logically, physically, and geographically, DCS is decentralized. At the same time, the system also integrates computer technology, network technology, communication technology and automatic control technology. MA-0185-100 is a new type of control system that disperses risk and centralizes control. DCS has been widely used in power, metallurgy, petrochemical and other industries.
