| 摘 要： | 本文提出了电子电路故障定位的多传感器模糊信息融合方法。通过测试电路中的被诊断元件的工作温度和工作电压两个物理量，得出模糊信息理论中两传感器对各待诊断元件的故障隶属度，再利用模糊信息融合，确定故障元件，并通过单传感器诊断结果与模糊信息融合诊断结果比较，说明多传感器融合的优越性。

| Abstract: | A Information fusion method for circuit malfunction diagnosis based on Multi-sensors fuzzy information is presented. By measuring the temperature and voltage ofc ircuitc omponents,t hem alfunctionr elativem embership degrees of two sensors to circuit component is gotten, and malfunction component is found by using fuzzy information fusion. By comparing the diagnosis results based on separate original information and fused information respectively, it is shown that the latter is more accurate than the former in the circuit malfunctionr ecognition. |
