应用模糊数据融合实现电子电路的故障诊断

Circuit Fault Diagnosis Based on Fuzzy Data Fusion

本文将模糊数据融合技术引入电子电路故障诊断之中 .通过测试电子电路中的被诊断元件的工作温度和工作电压两个物理量 ,得出两传感器对各待诊断元件的故障隶属度 ,在对隶属度值进行数据融合的基础上 ,确定故障元件 ,并通过单传感器诊断结果与融合诊断结果比较 。

A fuzzy data fusion method is used in circuit fault diagnosis. By measuring the temperature and voltage of circuit component, the membership function of two sensors to circuit component is gotten ,and the fusion membership function is gotten by using fuzzy data fusion, and fault component is found. By comparing the diagnosis results based on separate original data and fused date respectively, it is shown that the latter is more accurate than the former in the circuit fault recognition.
