本文阐述为某热电厂设计并实施的分散型数据采集控制系统。该系统已投入运行并以常规的方式进行控制。整个系统以两级分级结构为基础设计。第一级是以好几个微处理机为基础的分散型远程站,它们就地执行绝大多数控制任务。第二级(或主控站)是用小型计算机来进行协调操作以及驱动显示终端和其他外部设备。 This article describes a distributed data acquisition control system designed and implemented for a thermal power plant. The system is up and running in the usual way. The entire system is based on a two-level hierarchical structure design. The first level is a decentralized remote station based on several microprocessors that perform most of the control tasks in-place. The second level (or master station) uses a small computer to coordinate operations and drive display terminals and other external devices.
