摘要
可靠、快速的数据传输是建立地震预警系和烈度速报系统的基础。分析地震预警和烈度速报对通信的需求,基于现代通信技术,从稳定性、可靠性、有效性和抗毁需求出发,通过给出适用于地震预警系统和烈度速报系统的数据通信模式。就预警系统而言,目前正在发展中的SDH光纤通信模式是最佳的方案;烈度速报而言,可以采用3G移动通信并辅以北斗卫星短报文通信。
Reliable, fast data communication is the basis of earthquake early warning and intensity rapid report sys- tem. We analyze the communication needs of earthquake early warning and intensity rapid report, and give the data communication mode which is stable, reliable, effective and survivable for earthquake early warning and intensity rapid report system based on modern communication technology. SDH optical fiber communication mode being in the development is the best solution in the early warning system, however we could choose 3G mobile communication supplemented by Beidou satellite short message conmmunication in intensity rapid report system.
