| 摘 要： | 实时监视地震波形和大震报警结合在一起，可以有效地提高工作效率。通过软件实时监视地震事件，台站分析人员既可以真实地看到高灵敏度的地震波形，又可以根据需要压缩放大波形，也可以做任意频段选择和滤波处理，保证了波形连续。对于大地震实施软件报警，使得台站可以根据本台的背景噪声，适当地选择报警幅度，既可避免过多的小震报警，又可以减少盲目、频繁地操作调用查看波形。适合台站工作，为台站人员提供了方便。

| Abstract: | It is can raise efficiency to combine real time monitor seismic waveforms with big earthquake alarm. The seismic event can be, either really watched with high sensitive seismic waveforms,or zoom in or zoom out one through monitoring software by the analyst. Of course the user can select any channel and filter without reset the computer, by use of thread program technology.The station people can adjust amplitude of ground motion to fit local backgrgund noise for big earthquake alarm. To use this software not only reduce numbers of small earthquake alarm but also avoid frequently check waveforms. This software suits station work and is convenient for station person. |
