摘要

基于提升模式研究了二代小波包(SGWP)算法，成功用于爆破振动测试数据的噪声去除，为准确提取爆破振动信号特征奠定了基础。采用SGWP改进算法快速、精确地实现了爆破振动信号各频带相对能量分布分析，同时选取主振频带内能量占优的主分析二代小波包表征爆破振动信号的时频特征。将SGWP算法引入到爆破振动效应分析领域，为构建大型网络化爆破振动测试系统与控制平台提供了技术支持和数据分析基础，具有较好的应用前景。

Abstract

The Second generation wavelet packet (SGWP) algorithm was studied under the mode of lifting scheme，and was successfully used in the de-noising of blasting vibration monitoring signals, which laid important foundation for extracting characteristics of blasting vibration signals. The relative energy distribution of each frequency band was got quickly and accurately, based on the SGWP algorithm, and the energy dominant wavelet packets were extracted to express the time-frequency and energy characteristics of blasting vibration signals. SGWP algorithm was introduced into blasting vibration effects analysis fields, which will provide technical supports and data analysis basis for the construction of large network blasting vibration monitoring and control platform, so it will has a good application prospect.
