Lifting wavelet packet decomposing algorithm based on optimal basis was applied to de-noising and analysis of energy distribution in the paper, in order to ensure accuracy and efficiency of engineering blasting network monitoring and forecasting system. Based on lifting wavelet packet multi-scale transform, improved search algorithm for optimal basis was used which can meet online processing of complicated signals. In application examples, noise was filtered by lifting wavelet packet decomposing algorithm, and energy distribution of every frequency band was acquired precisely. Application of the algorithm to analysis of blasting vibration signal can provide research basis and technique supports for studying and controlling of blasting vibration hazards, and it has a good application prospect.
