摘　　要：根据干涉型光纤传感系统信号的特点,比较分析了数字滤波、小波去噪等方法的去噪效果及影响因素,同时,利用小波包能量分析方法,深入分析采集信号的特征向量,定义了线路状态检测指标,研究了各类振动的特征差异。Based on the characteristics of the interferometric optical fiber sensing system, the paper compared and analyzed the denoising effect and influenced factors of methods such as digital filtering, wavelet denois- ing. We also analyzed in depth the feature vector of the acquired signals, defined the line state detection index, studied the differences in characteristics of various types of vibration using the analysis method of wavelet packet energy.
