摘　　要：针对水电站大坝溢洪闸门综合自动化这样复杂的系统 ,提出了按系统功能分解策略进行分析的模块化故障诊断策略 ,采用 IDEF0方法建立了闸门综合自动化系统的功能结构图。在面向对象的知识表示法中引入产生式规则表示法 ,将两者进行融合 ,提出了一种混合式的面向对象的知识表示方法来构造水电站大坝溢洪闸门综合自动化故障诊断专家系统。利用面向对象技术的封装性、继承性等特点 ,使系统的代码重用、消息传递、图形化界面的实现取得了较好效果 ,增强了专家系统开发工具的结构化知识表示能力 ,有利于开发大型专家系统。Aimed at the complicated system of spillway sluice integrated automation of hydropower station dam, modularized fault diagnose strategy based on system functional decomposition analysis is introduced, and the functional structure diagram of the sluice integrated automation system is drawn by IDEF0 method. An expert system of fault diagnose for hydropower station dam spillway sluice integrated automation is established by introducing production rule representation into object-oriented knowledge representation. By using the characteristics of encapsulation and inheritance of the object-oriented technique, the system performances, such as code reuse, message transformation and implementation of graphic interface, are much improved. The structural knowledge expression ability of expert system development toll is reinforced, and it is suited for large-scale expert system development.
