海南数字地脉动参数处理系统

摘要
该文编制了一个基于服务器数据库的地脉动参数自动处理系统,它利用FTP协议每天自动从测震台网中心的服务器中获取地脉动波形,自动计算各个地脉动参数,并自动把参数添加到地脉动参数数据库中。同时编制地脉动参数查询与图形显示系统,用户可使用IE浏览器查看地脉动参数和绘制变化图形。初步研究认为,在海南及邻区显著地震前和地震活动活跃时地脉动参数有一定的异常变化。
The processing system of microseism parameters based on server and database at digital seismic network has been developed.The system daily gains microseism waveform data from the servers at the seismic network center by means of FTP protocol,then automatically calculates microseism parameters and sends the microseism parameters into the database.The inquiry and graphic display system has been developed based on the server about the microseism parameters.Anyone can inquire the microseism parameters and draw the change figures of the microseism parameters only by means of the IE browser.The authors discover that the microseism parameter have evidently anomalous variation before the marked earthquakes and during the active seismicity in Hainan region and its neighboring areas through the preliminary study.
