基于互联网的强震仪监测网络系统的设计与实现

摘要

密集布设的MEMS强震仪台网获取的准实时强震观测数据,可以为震后灾情快速判断和平时地震学基础研究提供科学依据.本文阐述了利用3G/4G无线通信和L2TP (Layer Two Tunneling Protocol,第二层通道协议)VPN(Virtual Private Network,虚拟专用网络)技术,基于互联网组建MEMS(MicroElectromechanical System,微机电系统)强震仪监测网络的主要步骤和实现过程,实现了MEMS数据的实时传输.提供了一种简单的组网模式,为建立灵活、实用、覆盖面广,并具有一定安全性的密集监测网络提供参考.%The quasi-real-time strong motion observation obtained by the dense MEMS seismic seismograph network can provide efficient data for the rapid judgment of the post-earthquake disaster.This paper described the main steps and implementation process of MEMS accelerograph monitoring network system based on Internet,by using 3G/4G wireless communication and L2TP VPN technology,to realize the real-time transmission of MEMS data.Taking a simple networking model as an example,the results will help to provide a reference for establishing a flexible,practical,wide coverage intensive monitoring network with a certain security.
