Abstract

The invention discloses a de-noising method for a blasting vibration response signal; the method comprises the steps: obtaining a to-be-processed blasting vibration response signal, and obtaining a high-frequency blasting vibration response signal and a low-frequency blasting vibration response signal through wavelet packet decomposition; then performing threshold quantization processing on the high-frequency blasting vibration response signal and the low-frequency blasting vibration response signal to obtain a quantized high-frequency blasting vibration response signal and a quantized low-frequency blasting vibration response signal; and performing wavelet packet inverse transformation on all the quantized high-frequency blasting vibration response signals and all the quantized low-frequency blasting vibration response signals to obtain target blasting vibration response signals. Therefore, the method and the device do not depend on Fourier transform as a unique means for removing the noise of the blasting vibration response signal any more, wherein the noise of the blasting vibration response signal can be removed through wavelet packet transform processing of better time-frequency localization analysis on the signal containing a large amount of medium-frequency and high-frequency information, thereby achieving effective denoising of the signal.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a denoising method, device and electronic equipment for blasting vibration response signals. Background technique [0002] In recent years, with the rapid improvement of the intelligent level of mining equipment, the demand for ensuring the safety of mine roadway operations is also increasing. Among them, the safety judgment of the surrounding rock of the mine roadway under the blasting load mainly depends on the analysis based on the original blasting vibration response signal. However, the original blasting vibration signals obtained through mine site monitoring are often mixed with certain noises, which lead to low accuracy and poor reliability when processing and analyzing the signals to obtain their time and frequency domain characteristics. [0003] In related technologies, in order to weaken the noise existing in the original blasting vibration response ...
