ABB-KUC321AE-HIEE300698R1 分散控制系统

ABB-KUC321AE-HIEE300698R1是一款分散控制系统（DCS）是以微处理器为基础，采用控制功能分散、显示操作集中、兼顾分而自治和综合协调的设计原则的新一代仪表控制系统。它采用多层分级、合作自治的结构形式，具备集中管理和分散控制的主要特征。目前，DCS在电力、冶金、石化等各行各业都获得了极其广泛的应用。

具体来说，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职，互不干涉，各自完成自己的目标。这些目标是整个系统目标中的分目标。

在ABB-KUC321AE-HIEE300698R1，过程控制级实现了信号的输入、变换、运算和输出等分散控制功能。这些控制装置可能包括过程控制单元、现场控制站、过程接口单元等，虽然结构形式可能不同，但大致可以统称为现场控制单元（FCU）。

此外，DCS的硬件和软件都是按模块化结构设计的，ABB-KUC321AE-HIEE300698R1其开发过程实际上是将系统提供的各种基本模块按实际的需要组合成为一个系统，称为系统的组态。操作站则用来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。

ABB-KUC321AE-HIEE300698R1 is a distributed control system (DCS) based on microprocessor, using decentralized control functions, centralized display operation, taking into account the design principles of division and autonomy and comprehensive coordination of a new generation of instrument control system. It adopts the structure form of multi-layer classification, cooperation and autonomy, and has the main characteristics of centralized management and decentralized control. At present, DCS has been widely used in all walks of life such as electric power, metallurgy and petrochemical industry.

Specifically, decentralized control means that the control part of the system is manifested as a number of decentralized and relatively independent sub-control institutions. Each of these institutions performs its own functions within its own scope, does not interfere with each other, and achieves its own goals. These goals are sub-goals of the overall system goals.

In ABB-KUC321AE-HIEE300698R1, the process control stage realizes the decentralized control functions of signal input, transformation, operation and output. These control devices may include process control units, field control stations, process interface units, etc., although the structural form may be different, they can roughly be collectively referred to as field control units (FCU).

In addition, the hardware and software of DCS are designed according to the modular structure, ABB-KUC321AE-HIEE300698R1 its development process is actually to combine the various basic modules provided by the system into a system according to actual needs, 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.
