摘　　要：为解决当前航空电源系统故障诊断存在的不足,提出将故障树分析法与寻址技术相结合的方法。在以PCI总线和计算机编程技术为核心的测试平台的基础上,分析航空电源系统的结构和工作状况,设计出适用于航空电源系统的故障诊断系统,并以某类航空电源系统为例进行实验验证。结果表明:该方法测试效率高、故障分析到位、定位准确,能解决航空电源系统故障诊断中的不确定性问题以及复杂系统发生故障时的多故障现象,提高航空电源系统的维修性和安全性。In order to solve the shortcomings of the fault diagnosis of the current aviation power system, the method of combining fault tree analysis with addressing technology is proposed. On PCI bus and computer programming technology as the core of the test platform, on the basis of analysis of aircraft power supply system structure and working condition, design is suitable for the aircraft power system fault diagnosis system, as a case study of certain types of aircraft power supply system for experimental verification. Test results show that the method is of high efficiency, fault analysis in place, accurate positioning and can solve the problem of the uncertainty in aircraft power system fault diagnosis and fault phenomenon of complex system failure occurs, improve the maintainability of aircraft power supply system, and security.
