A Fault Diagnosis System for Main Fan in Coal Mine Based on BP Neural Network

[摘要] By analysing the three-layer structure of BP neural network and the fault characteristics of main fan in coal mine, the BP network structure of fault diagnosis is constructed, and the learning model and algorithm of BP network are designed. The experimental simulation shows that the accuracy of the fault diagnosis of the main fan of the coal mine is improved.
