Abstract: This paper introduces a web-based remote fault diagnosis expert system of hydroelectric generation sets with WebService and ActiveX technologies. The system is divided into three parts: power plants, diagnosis center and experts. The WebService is adopted to capture, analyze and process data, and the ActiveX is used to present data and provide interaction with users. Comparing with a classical client-side application, the system is completely web-based and introduces the method separating data capture, analysis and representation for cross-platform calling data and analysis algorithm. That greatly improves the reusability and maintainability of the system.

摘要： 本文提出了一种利用WebService和ActiveX技术构建基于Web的远程诊断系统的实现方案。该系统由电厂、诊断中心和专家三部分组成，采用WebService实现数据的获取和分析处理，采用ActiveX实现数据的表达以及与用户的交互。与传统的客户端应用相比, 这个系统是完全基于Web的，并且为了实现数据和分析算法的跨平台调用，引入了数据获取、分析和表达相分离的方法。这使得该系统的可复用性和可维护性也得到了很大的提高。
