DCS控制系统操作员站功能分析
摘要
 我国火电厂计算机应用大致可分为2个阶段，一是计算机监视系统(DAS)阶段，二是计算机监控系统，即采用以微机为基础的DCS阶段。前者只有数据采集功能，后者兼有控制功能，使计算机应用向纵向发展，对提高电厂自动化水平起着决定性作用。作为一种非常重要的控制手段，分散控制系统(DCS)已经在电力工业自动化中得到广泛应用，其硬件设备由管理操作应用工作站、现场控制站和通信网络组成。
 其中DCS控制系统操作员站用于监控生产，在生产控制中占着重要地位。早期的DCS操作员站存在着许多问题，因为操作员站的硬盘有活动部件，又如键盘、鼠标在运行人员的多次操作后容易出现故障。CRT24小时连续运行都比较容易损坏。在长时间运行后出现老化、显示器故障、DCS设备的备件供货单一、昂贵等问题，严重影响了生产。为了操作员站更加适合长时间生产运行，本文通过对操作员站的基本结构、发展历程、功能、和网络的分析和概述，得出开放性好，具有人性化的人机界面的通用操作员站更加适合于现代生产的结论。

The Functional Analysis of Distributed Control System Operators
Abstract
 China's thermal power plant computer applications can be broadly divided into two stages, first computer surveillance system (DAS) stage and the second is computer monitoring system, that is, to use computer-based DCS stage. Only the former functions of data collection, which both control so that the computer application to the vertical development, the level of automation to improve plant plays a decisive role. As a very important means of control, distributed control system (DCS) in the power industry has been widely used in automation, its hardware operation by the management of workstations, on-site control stations and communication networks.
 DCS control system which station operators to monitor production and production control in an important position. Early DCS station operators there are many problems, because the drive station operators have moving parts, and if the keyboard, mouse in the running when you are prone to repeated failures. CRT24-hour continuous operation is relatively easy to damage. In the long run after the aging, monitors fault, DCS equipment spare parts suppliers a single, expensive problems, a serious impact on production. In order to station operators more suitable for long production run, the paper through the operator at the basic structure, the development process, functions, and network analysis and overview, drawn open, and with a human face of the common man-machine interface operators Points more suitable for modern production to the conclusion
Key words: DCS, operator stations, man-machine interface, network of operators
