摘要
为领域专家提供一种有效的知识获取方法。该方法综合各种设备故障诊断知识获取方法的优点，引入系统论的概念和思想，使知识获取过程系统化和程式化，强调和引入了设备对象功能技术物理效应、伴随技术物理效应和可测性研究。提出的设备故障诊断模型知识获取方法已应用于建立某一抽水蓄能机组的诊断知识模型，表现出了操作的方便性，较好地解决了所获取知识的完备性和一致性问题。该方法使设备故障诊断知识获取工作向工程化的方向迈进了一步。
An effective method of knowledge acquisition for domain experts in presented. It combines the advantages of several kinds of knowledge acquisition methods of malfunction diagnosis and adopts the concept and thought of systematics to formulate and systematize the process of knowledge acquisition. Emphasis is placed on the basic and accompanying technical and physical effect achieving the equipment functions and measurable study. Having been applied to build the malfunction diagnosis model of a hydroturbine generator unit in a pumped storage power station in China, this method solves the problems of completeness and unanimity of knowledge to some extent and shows to be easy to operate. It is expected this method could make progress for knowledge acquistion engineering of malfunction diagnosis problems.
