卫星通信在地震烈度速报数据传输中的应用

摘要

在分析地震烈度速报数据传输特点后,提出将卫星通信引入烈度速报系统.通过对目前中国使用较多的北斗卫星、海事卫星、铱卫星系统和VSAT卫星系统进行对比,选取铱星短消息和海事卫星数据流这两种典型通讯方式,设计由通用数字强震仪与卫星通信系统结合地震速报通讯模块组成的实验系统,实现数字强震动记录信息通过卫星信道进行的数据传输,展现卫星通信在地震烈度速报数据传输中的应用前景.%According to the characteristics of rapid report data transmission,this article discuses about how to use satellite technology in rapid report system.After the comparison of various aspects of the current domestic communication mode,we select the short message of iridium satellite and Inmarsat data stream.The experiment system is designed by the general digital accelerograph and satellite communication system with seismic communication module,and data transmission is realized.It is show that satellite communication can play a role in earthquake rapid report data transmission.
