摘　　要：在分析某型自行火炮电气系统的失效模式与故障机理的基础上,建立故障树,采用基于规则的故障树分析技术对故障树模型进行分析,并结合Rete匹配原则,运用E-R关系数据库模型建立基于故障树的专家系统知识库。采用基于规则的推理,以正向推理为主,反向推理为辅的混合推理策略对推理机进行实现。结果表明,该故障诊断方法能较好地解决专家系统的知识获取难题,提高电气系统故障诊断的智能化水平。On the basis of analysis the fault mechanism and failure mode of the electrical system of certain type Self-propelled gun. Established fault tree, and using based on regulation fault tree progress analysis to fault tree model, combine Rete, used E-R date-base model, Established expert system knowledge base of fault tree-based. Using regulation ratiocination, to forward-based reasoning, backward reasoning as auxiliary＇s blending reasoning strategy processed realized to reasoning. Result shows, the method can solved knowledge acquisition problem, improved intelligentize level of electrical system fault tree.
