摘　　要：将小波分析进行信号抑制技术应用于电牵引采煤机电机故障信号去噪和检测 ,利用MATLAB可方便直接地进行信号某些频率区间的抑制和衰减 ,从而清楚监测到电机电流故障信号 。The application of the wavelet signal analysis technique to the noise removement and the monitoring test of the electric mining machine have successfully monitored and decreased the engine current trouble signal in some frequency range,on the other hand,so does the simulation result.

关 键 词：信号去噪 采煤机 截割电机故障检测 电流信号 小波分析
