军用电子设备故障诊断专家系统知识库的建立

Establishing Knowledge Base of Fault Diagnosis Expert System for Military Electronic Equipment

知识获取是建立专家系统的关键 ,尤其是获取专家的经验知识比较困难时 ,挖掘被诊断设备的原理知识非常必要。在充分考虑军用电子设备特点的基础上 ,提出了一种从被诊断设备原理性知识中总结规则的方法 ,该方法依靠设备原理的定性模型 ,利用现有的各种设计技术资料 ,具有简单 ,直观 ,方便的特点 。

Knowledge acquisition is the kernel of constructing an Expert System(ES). It's necessary to dig the schematic knowledge from equipment to be diagnosed when it's difficult to get experience knowledge from experts. Based on the consideration of military electronic equipment, a method that induces rules from schematic knowledge is proposed. The method relies on the equipment's qualitative modeling and utilizes various available data. It's simple, intuitionistic, easy to use and suitable for acquiring knowledge for fault diagnosis ES from electronic equipment.
