一种基于PLC的火电厂微机监控系统及其数据通信的实现

Programmable Logic Controller based Microcomputer Monitoring System for a Thermal Power Plant and Realization of Its Data Communication

以鹤壁电厂DAS改造项目为例 ,基于Windows下的DDE和NetDDE机制 ,论述了系统的结构、硬软件配置、性能及网间数据通信的实现 。

With the data acquisition system (DAS) modification project of Hebi Thermal Power Plant being taken as an example and based on DDE and Net DDE mechanism under Windows environment the authors expound a monitoring system structure, hardware and software configuration, its performance and a realization of network data communication. All the above has provided a well thought out approach for the development of a microcomputer based monitoring system for use in thermal power plants.
