This paper will be used Daubechies wavelet decomposition the output response mutation signals multi-storey,and detect the singular signal. It will Get the Signals mutation point which Corresponding to the Great value of Wavelet,SO to determine whether emergency-type sensor fault.
输出响应突变信号的频带较宽,包含低频分量和高频分量,本文采用Daubechies小波将故障传感器输出响应突变信号进行多层分解,进行奇异信号检测,获得信号的突变点对应于其小波的极大值,从而判断出传感器有无突发型故障。
