运用EMd算法实现了信号的处理，并且对信号进行傅里叶变化获得其频域特征，冲采样后获得特征参数建立神经网络与实验进行识别-

EMd use signal processing algorithm, and the Fourier transform of the signal in the frequency domain to obtain its characteristic red after sampling to obtain the characteristic parameters to establish the neural network and experimental identification, a month of effort
