摘　　要：为了提高装备故障诊断效率,介绍了一种基于多信号流图模型的新型故障诊断方法。基于TEAMS Designer软件工具,建立了某自行高炮供电系统多信号流图模型。通过对该系统多信号流图模型进行分析,针对故障现象设计出了合理有效的故障诊断策略,通过实际的故障诊断应用及与传统的测试诊断方法比较,显示出该诊断方法的优越性和有效性。In order to improve the efficiency of fault diagnosis for equipment, a novel fault diagnosis meth- od based on multi-signal flow graphs model was introduced. And it built multi-signal flow graphs model for an antiaircraft power supply system using TEAMS Designer. By the analysis of the system model, It finally designed a rational and effective strategy for fault diagnosis. The superiorly of this diagnostic method was proved by application and comparing to traditional fault diagnosis method.
