火电厂实时系统数据通道的设计与实现

以某火电厂实时系统中的机组部分和全厂远动SCADA部分为例,介绍了实时系统的核心部分,即数据通道的设计与实现。以实时信息系统数据通道中的数据采集、传递、处理与存储、用户与数据库的交互等为主要研究对象,在管理信息系统(MIS)与生产自动化系统的数据通信方面采用基于TCP/IP的Socket网络通信方式;在MIS网上的信息发布与接收架构方面采用Web浏览器/Web服务器/数据库(DB)服务器3层结构(即B/S结构),并采用新颖的ActiveX组件应用与ASP应用相结合的Web应用方式加以实现。

Design and Implement of Data Channels in RT-MIS for Power Plant

With the retrofit project of RT-MIS for a power plant, taking a unit and SCADA part of system as an example, the design and implement of data channels in RT-MIS is put forward. The data stream in the system data channels including data transfer, processing, store and interaction with users is the core study objects. TCP/IP based socket network communication method is used on data communication between MIS and automation systems. And ‘Web Browser/Web Server/Database Server’ structure (B/S structure) with ‘web application frame including ActiveX components and ASP applications’ method is applied on Internet information exchanging structure in the MIS network.
