摘要
故障诊断知识表示是知识处理中最基本的一个问题，其目的在于把领域诊断专家的知识以一定的表达范式表示出来。针对电站锅炉的故障诊断问题，提出了面向对象基于框架、规则、模型与过程集成的广义故障树知识表示方法。它是在故障树的基础上，以诊断对象为中心，应用面向对象技术将多种单一的知识表示方法集成一种混合的表示形式，并给出电站锅炉系统广义故障树诊断对象描述实例。这种知识表示方法具有简洁、灵活、透明，且易于诊断推理的特点。
Fault diagnosis knowledge representation is a most basic issue in knowledge process. It is aimed at representing the knowledge of field experts with knowledge expression paradigms. A knowledge representation method of generalized fault tree is proposed and approached by applying objectoriented methodology in accordance with the issues of power plant boiler system fault diagnosis and its specific property. This method centers around diagnosis object. It is based upon a fault tree and is based on integrating of frame, rule, model and procedure. The application examples of power plant boiler system fault diagnosis are given. The method of knowledge representation has characteristics of terseness, agility, transparency and is easy to diagnose and infer.
