Abstract: Aiming at the limitations of traditional wavelet in blasting vibration signal feature extraction and analysis, a blasting vibration signal extraction method based on FPGA is proposed. Combined with FPGA technology, set the blasting vibration standard threshold and evaluation index, track and detect the blasting data according to the index, obtain the blasting vibration signal, denoise and clean it. Finally, the experiment shows that the best analysis signal decomposed by the blasting vibration signal extraction method based on FPGA can truly reflect the detailed information of the vibration signal in the actual application process, The time-frequency resolution is higher, which effectively breaks the limitations of blasting vibration signal feature extraction and analysis.
