| Abstract: | In view of the main ventilator breakdown which threats the coal mine production safety,uses the main component analysis and the wavelet analysis method for fault diagnosis to the main ventilator.Elaborated the main component analysis and the wavelet analysis principle,has established the main ventilator failure diagnosis data processing model.Based on this carries on the simulation experiment using Matlab to the gathering vibration signal,the results show that this method can judge the coal mine main ventilator breakdown type accurately. |
