智能化网络地震监控和实时数据处理系统

INTELLIGENTIZED NETWORK SEISMIC MONITORING AND REALTIME DATA PROCESSING SYSTEM

中国数字地震台目前所采用的数据处理软件存在下列不足:1)不能对含lg震相的地震定位;2)不能计算mB、mb震级;3)不能自动生成月报;4)不能实现数据共享和独立完成地震速报;5)近震参数计算误差较大;6)地震定位效果不好。为此,我们基于VisualBasic软件平台,开发出智能化网络地震监控和实时数据处理系统。该系统除克服了以上不足外,还实现了数字地震仪工作状况的实时监控、地震参数计算、地震速报、各种地震单台定位、地震事件检索查询、地震编目、震相反推分析、数据传输等功能。该软件囊括了数字地震台全部日常工作,减轻了台站人员的工作量,有助于提高地震监测质量,充分发挥了数字地震仪的优越性。该系统在洛阳台近1年的试用中取得了较好的效果。

As we know, the SSDP mutual analysis software for seismic data processing has been widely used in many digital seismic stations in China. However, some inefficient functions in the software have limited its applications, namely ： （1） Seism containing lg seismic phase cannot be located. （2） Magnitude mB and mb cannot be calculated. （3） Seismic catalogue cannot be generated automatically. （4） It depends on other software （for example SSB） to do the seismic instant report and the seismic data cannot be shared. （5） Precision in calculating local seismic parameters can＇t be guaranteed. （6） Epicenter can＇t be showed in the map. As a solution to these problems, we developed a new intelligentized network system based on VB （Visual Basic） for seismic monitoring and data processing. Compared with SSDP system, we added some new functions to the system, such as real-time monitoring of working status of seismic equipment, seismic parameters calculation and instant seismic reporting by itself. The implements also include searching of seismic events, automatic editing of seismic catalogs, analyzing of seismic phase and transmitting data. Our software has been used effectively in the Luoyang Station of Henan province over one year. It is able to deal with all daily works and alleviate the workload in digital seismic station, and it is helpful in improving the quality of seismic monitoring. The advantage of digital seismograph has been brought into full play.
