此包络中含有各种常用小波的分解和重构程序，如haar等-This envelope contains a variety of commonly used wavelet decomposition and reconstruction procedures, such as haar, etc.

本文研究的是利用奇异性指数实现对设备状态监视和故障预警功能。首先用LabVIEW 采集传感器电信号，然后对采集到的电信 号进行小波变换得到信号包络奇异点的奇异性指数，即设备运行状态的特征值-In this research project, we use LabVIEW to do wavelet-transformation to the signal collected by sensors in order to get singularity index from the sin
