摘　　要：为了准确、快速地对飞机电源系统故障进行诊断和排除,在分析某型飞机电源系统的失效模式和故障机理的基础上,建立故障树,采用基于规则的故障树分析技术对故障模型进行分析,引入正向推理和反向推理两种推理机制,研究了基于数据库技术的知识库的构建方法,设计某型飞机电源故障诊断专家系统。结果表明,该故障诊断系统的推理结果符合实际情况,提高了飞机电源系统故障诊断的智能化水平。In order to diagnose and troubleshoot the faults in aircraft electrical power system accurately and fast,we build the fault tree based on analysing the lost mode and fault mechanism of certain aircraft electrical power system,and adopt the rule-based fault tree analysis technology to analyse the fault models.Two reasoning mechanisms,the forward reasoning and backward reasoning,are introduced.We also study the construction method which is based on the database technique and knowledge base.The result shows that the reasoning outcome of the fault diagnosis system is in accordance with the actual situation,it improves the intellectualised level of fault diagnosis system for aircraft electrical power system.
