【摘要】 地震事件的自动判断是自动定位系统中至关重要的部分。本文结合数字波形特征的实际模型,提出了一套符合计算机化运行模式的新方法。对波形进行预处理后采用传统STA/LTA方法、波形延续性、台站集中性三者相结合的判断方法,有效的排除了干扰台站,保证了地震事件自动判断的准确性,并在实际运行过程中得到很好的验证。更多还原

【Abstract】 Automatic judgment for seismic event is a vital part of the automatic location system.In this paper,combined with the actual model of digital waveform characteristics,a new method in line with the computerized operating mode is proposed.Waveform is preprocessed using the traditional STA/LTA method combined with waveform continuity and concentration of stations.It effectively ruled out the interference stations and ensure the accuracy of automatic judgment of seismic events.It is well validated in the actual operation process.更多还原
