| 摘 要： | 以山西省测震台网为例,利用CWQL软件调取JOPENS5.2系统台站实时波形数据与对应台站参数,计算台基环境地噪声水平。分析认为,CWQL软件可用于日常测震观测系统数据质量检测,得到各测震台站各分向PSD功率密度函数分布及RMS值。研究结果实现了对山西数字测震台网连续波形数据质量、JOPENS系统台站配置参数的准实时监控及台站观测环境背景噪声功率谱密度的对比分析。

| Abstract: | Taking the Shanxi seismic network as an example,the real-time waveform data and corresponding station parameters of Jopens 5.2 system station are obtained by using CWQL software to calculate the environmental noise level of the station.The analysis shows that CWQL software can be used to detect the data quality of daily seismic observation system,and obtain PSD power density function distribution and RMS value in each direction of each seismic station.The quasi real-time monitoring of the continuous waveform data quality of Shanxi digital seismic network,the station configuration parameters of Jopens system and the comparative analysis of the background noise power spectral density of the observation environment are realized. |
