多源信息融合在故障诊断技术中的应用研究

从数据源的空间表示和信息源的可计算性两个方面阐述了信息融合应用于故障诊断的数学基础，然后引入信息论中有关“熵”、“条件熵”、“平均条件熵”和“互信息”等概念，从信息论的角度证明了信息融合在故障诊断中的有效性和实用性。最后结合信息融合技术与装备故障诊断实践，给出了具有通用性的信息融合故障诊断的模型框架。

Application Research on Fault Diagnosis Using Multi-sensor Information Fusion

The mathematical base of information fusion using in fault diagnosis is expatiated on the space expression of data source and calculabitity of information source. Then the validity and practicability for information fusing using in fault diagnosis is testified through introducing the concept of entropy, condition entropy, average condition entropy and mutual in- formation. Finally combining with the fact of army fault diagnosis, a general information fusion model is given.
