The invention relates to a fault diagnosis method for an aeronautical equipment system based on rule reasoning and a knowledge base, and the method comprises the steps: S1, constructing a fault diagnosis data model of the aeronautical equipment system, obtaining fault diagnosis information, and building a fault knowledge base; s2, performing rule reasoning based on the rule base to determine fault diagnosis information of the associated aviation equipment system, and obtaining a similarity result through the knowledge base; and S3, analyzing a fault diagnosis information similarity result of the aeronautical equipment system, sorting and outputting a fault diagnosis result. Fault features are extracted and recognized based on features of a keyword library; obtaining a matched associated LRU based on reasoning of a rule, and recording corresponding traceability information of the matched associated LRU; and realizing search matching of the fault diagnosis information based on search of the knowledge base, calculating information matching similarity, finishing similarity sorting of final fault results, and determining a fault diagnosis result of the aviation equipment system. According to the invention, the fault diagnosis efficiency of the aviation equipment system is improved, the fault diagnosis time is shortened, and the service cycle of the aviation equipment is prolonged.

    本发明涉及一种基于规则推理和知识库的航空装备系统的故障诊断方法,其包括:S1、构建航空装备系统的故障诊断数据模型,获取故障诊断信息,组建故障知识库;S2、基于规则库进行规则推理确定关联的航空装备系统的故障诊断信息,通过知识库获取相似度结果;S3、分析航空装备系统的故障诊断信息相似度结果,进行排序并输出故障诊断结果。本发明基于关键词库的特征提取识别故障特征;基于规则的推理获取匹配的关联LRU并记录其对应的追溯信息;基于知识库的搜索实现故障诊断信息的搜索匹配,计算信息匹配相似度,完成最终故障结果的相似度排序,确定航空装备系统的故障诊断结果。本发明提高了航空装备系统的故障诊断效率,降低了故障诊断的时间,延长航空装备使用周期。
