中文说明： 小波包分析提取振动信号中的特征频率，复化三点Gauss-lengend公式求pi，从先验概率中采样，计算权重，包括数据分析、绘图等等,对信号进行频谱分析及滤波，可以动态调节运行环境的参数。
English Description：
The characteristic frequency of vibration signal is extracted by wavelet packet analysis, PI is calculated by three-point Gauss lengen formula, and the weight is calculated by sampling from prior probability, including data analysis, drawing and so on. The frequency spectrum analysis and filtering of signal can dynamically adjust the parameters of operating environment.
