PI-ActiveView在基于B/S模式的电厂实时监控中的应用

Application of PI-ActiveView to Real-time Supervising of Power Plants Based on B/S Model

基于PI实时数据库平台构建的电厂实时监控系统,是利用PI数据库集成性和开放性特点与电厂自动控制专业知识相结合的典型二次开发实例。结合某电厂实时监控系统的Web程序开发实例,根据B/S模式特点和Microsoft的ActiveX技术,介绍了如何使用组件PI-ActiveView将PI流程画面和实时数据发布到客户端的方法,进而实现客户端用户通过IE浏览器来访问流程图及实时数据和监控电厂运行。

Basing on the platform of the PI （Plant Information） real-time system supervising of power plants is a representative example integrating the knowledge of automation and the specialty of PI system. According to an example of Web program development on one real-time system supervising of power plants, how to develop the flow picture and real-time data on PI to the client with PI-ActiveView is introduced on the basis of B/S model and ActiveX. Thus, users can view flow picture and real-time data and supervise operation by means oflE browser.
