以西安基准地震台为例,介绍利用地震台站现有设备资源和当前较为实用的网络接入方式,对地震速报网络进行备份和技术改造.结果表明,3种网络备份方案可以保证地震台站日常数据报送和大震速报工作对网络通信需求,降低大震速报时间延迟和网络不通次数,对其他地震观测台站具有借鉴作用.%Aiming at providing a stable network communication, and improving the speed of earthquake rapid report, the technical reformation of the earthquake rapid reporting network was carried out in Xi'an Seismic Station, using the available network equipments in the station and the current network accessing ways, e. G. , ADSL, fiber and wireless network. The results indicate that the network backup projects can successfully guarantee the network demands of daily data-delivery and earthquake rapid report in the station, and lower the delay of earthquake rapid report and the block of network. Therefore, these network backup plans have important significance and referential value for such seismic station, which are always located in the remote mountain area.
