基本结构
DCS是Distributed Control System的缩写,直译为“分布式控制系统”。由于产品生产厂家众多,系统设计不尽相同,功能和特点也各不相同。
国内在翻译时,也有不同的称呼:
分散控制系统(简称DCS)
集散控制系统(简称TDCS或TDC)
分布式计算机控制系统(简称DCCS)

系统组成
三站:工程师站、操作员站、现场控制站、系统网络
处理一切与运行操作有关的人机界面(HIS,Human Interface Station,或OI,Operator Interface,或MMI,Man Machine Interface)功能的网络节点。
主要功能:为系统的运行操作人员提供人机界面,使操作员可以通过操作员站及时了解现场运行状态、各种运行参数的当前值、是否有异常情况发生等,并可通过输入设备对工艺过程进行控制和调节,以***生产过程的安全、可靠、高效。
场控制站
现场控制站是DCS的核心,是对现场I/O处理并实现直接数字控制(DDC)功能的网络节点。
系统主要的控制功能由它来完成,系统的性能、可靠性等重要指标也都要依靠现场控制站***。
其设计、生产及安装都有很高的要求,是分散控制系统中的主要任务执行者。
系统网络
系统网络是连接系统各个站的桥梁。由于DCS是由各种不同功能的站组成的,这些站之间必须实现数据传输,以实现系统总体的功能。
系统网络的实时性、可靠性和数据通信能力关系到整个系统的性能,特别是网络的通信规约,关系到网络通信的效率和系统功能的实现。

Ground Fault Circuit Interrupters (GFCI’s): GFCI’s are designed to protect people from the dangers of electrical shock. These circuit breakers are typically installed on circuits where water sources may be present. The National Electrical Code (NEC) requires ground fault circuit protection in the garage, outdoor areas, bathrooms, and in spa areas within the home. The QO™ and Homeline™ Ground Fault Circuit Breakers provide Class A protection, sensing and responding to very low levels of ground faults by tripping and shutting off power, preventing serious electrical shock to people. • Combination Arc Fault Circuit Interrupters (CAFCI’s): CAFCI’s provide protection against series and parallel arcs. Arcing is a precursor to many electrical fires. Square D QO and Homeline CAFCI’s help protect people and property from fires caused by electrical arcing. These devices continuously monitor the branch circuit and trip when a potentially dangerous condition is detected. • Dual Function (CAFCI + GFCI) Two critical, state-of-the-art technologies in one device: The innovative Square D QO and Homeline Dual Function Circuit Breakers combine two critical, state-of-the-art technologies: Combination Arc Fault and Ground Fault (Class A) Protection in one circuit breaker. Dual Function Circuit Interrupters provide a higher level of protection than any other residential circuit breaker. These devices protect the entire circuit on which they are installed, not just a part of the circuit like electronic receptacles do.
