利用CWQL检测JOPENS5.2系统仪器参数正确性

摘要

Taking the Xinlinhaote Seismic Station as an example,with the CWQL software for acquiring the real-time data from the JOPENS 5.2 system and the parameters of the JOPENS 5.2 system,the accuracy of instrument parameters of JOPENS 5.2 system is detected by calculating the platform noise level in this research.It is found that CWQL software can be applied to detect the data quality from seismic observation system.It allows the real-time automatic analysis of the observation data received from each station with probability density function.Consequently,PSD density probability distribution and RMS value are obtained from every station and thus the accuracy of JOPENS 5.2 system parameter can be determined.%以锡林浩特地震台为例,利用CWQL软件调取JOPENS5.2系统台站实时数据与对应台站参数,计算台基噪声水平,检测该系统仪器参数正确性.分析认为,CWQL软件可用于日常地震观测系统数据质量检测,实现实时自动运用概率密度函数方法处理地震观测数据,得到各地震台站各分向PSD概率密度函数分布及RMS值,从而判断JOPESN5.2系统仪器参数正确性.
