This paper proposes an intelligent fault diagnosis method based on rough set and BP neural network.First
for these equipments contain a huge number of redundant data
this method pretreated the preliminary data for fault diagnosis to reduce raw data attribute by use of rough set
and then analyzed the processed data with BP neural network technology which improved by using LM algorithms to implement the fault diagnosis.It established a model of fault diagnosis based on RS-LMBP algorithm
and the examples demonstrate that the method is feasibility and high efficiency.
