摘要
通过统计四川省数字测震台网在接入SDH光纤通信台站时的运行情况,分析现阶段地震台站备用通信系统存在的问题,提出针对光纤通信台站基于3G/4G无线通信在线式备份链路设想和系统解决方案,以提高台站数据运行率。
Through the statistics of Sichuan seismic network in the operation of SDH optical fiber communication station ease, we analyge the present seismic station backup communication system problems, and propose solutions for optical fiber communication stations of 3G/4G wireless communication system and online backup scheme in order to increase in station data transmission rate.
