| 摘 要： | 根据广东地震台网(下简称广东台网)台站数据传输采用多种方式的现状,统计和分析了2009年1月1日至2014年12月31日期间44个台站的数据传输质量。阐述了6种传输方式的基本原理,分析了各种传输方式的质量和产生断记的原因,提出如何解决传输过程中所遇到的各种问题。从信号的传输质量、运维成本、地震速报和未来地震预警需求等多方面着手,分析总结了各种传输方式的优劣,为提高台网运行率和台站数据传输质量,提出了"以SDH为主、多种传输方式并存"传输方式。

| Abstract: | According to the current situation that there are varieties of ways to transfer station data in the Guangdong seismic network (here in after referred to as Guangdong network),the statistics and analysis of data transmission quality during the period of January 1st,2009 to December 31st,2014 of 44 stations have been made. Then the basic principle of the 6 transmission modes has been expounded in this paper. Firstly,the quality of various transmission modes and causes of the interruption have been analyzed. Then the solutions to the various problems encountered in the transmission process have been put forward. At last,based on the signal transmission quality,operation,maintenance costs,the future earthquake early warning of seismic demand,the merits and demerits of the various transmission modes have been analyzed and summarized. Then mostly in SDH and multiple transmission modes coexist transmission mode have been proposed to improve the network operation rate and data transmission quality. |
