Seismic station network waveform data quality monitoring method and device

Abstract

The embodiment of the invention discloses a seismic station network waveform data quality monitoring method and device. The method comprises the steps: carrying out calculation through a preset background noise power spectrum probability density function to obtain a power spectrum probability density value of a signal; carrying out calculating by using a preset One-Sided algorithm in a Matlab calculation process to obtain bilateral power spectral density, and performing ground noise effective root-mean-square calculation by using a preset algorithm formula according to the bilateral power spectral density to obtain ground noise level information of the station; carrying out calculating by using a preset cross-correlation function of a plurality of background noises based on time migrationinformation to obtain clock error information of the station; and monitoring and analyzing the seismic station network waveform data quality according to the power spectrum probability density value,the ground noise level information and the clock error information. By adopting the method provided by the invention, the waveform data quality of the seismic station network can be monitored in realtime, and the efficiency and robustness of monitoring the waveform data quality of the seismic station network are improved.
