模糊信息融合及其在发动机失火故障诊断中的应用

Fuzzy Information Fusion and Its Applications in the Fault Diagnosis of Engine Misfire

由于发动机结构复杂,造成发动机失火故障的因素很多, 使故障诊断及故障定位非常困难.为此本文提出了一种基于模糊信息贴近度分析的信息融合方法,并用以诊断某装甲车辆发动机失火故障,取得了满意效果.

Because the construct of engine is complex, many factors could make engine misfire. So fault diagnosis and orientation are difficult. A method of information fusion based on fuzzy information approximation analysis is advanced in this paper. It has been used to diagnose the engine misfire of armored car, and the result is satisfactory.
