摘要
依托"中国地震数据观测网络"项目,中国地震局地震预测研究所建立了以十三陵地震中心台为前兆台网部,8个无人值守的前兆台站为一体的前兆观测系统。这套系统利用中国联通的CDMA 1X网络将台站接入到Internet网络,并利用VPN(Virtual Private Network)技术在Internet网络上开辟一条安全、稳定传输隧道,实现了前兆台站、观测设备与十三陵前兆台网部的信息集成。文中以十三陵地震前兆观测系统为例,主要介绍了如何利用CDMA 1X无线网络和VPN(Virtual Private Network)技术实现前兆观测系统信息集成。十三陵地震前兆观测系统的正常运行证明,利用CDMA 1X+VPN技术的前兆观测系统组网模式可以做到投资少、见效快、传输可靠等优势,值得推广应用。
The Institute of Earthquake Science of China Earthquake Administration has established an earthquake precursory observing system which includes an earthquake precursory network center-Shisanling earthquake central site and 8 unmanned earthquake precursory observing sites, relying on ＂China Digital Earthquake Observing Network＂ program. The precursory observing sites or observing equipments are linked to the Internet with the CDMAIX wireless network of China Unicorn, and then accessed to the Shisanling precursor observing network center by opening up a safe, stable transmission tunnel between sites and the network center with the VPN （Virtual Private Network） technology. Take the Shisanling earthquake precursory observing system as an example, this paper mainly introduces how to integrate earthquake precursory observing system by the use of VPN technology and CDMA （Code Division Multiple Access） wireless network. The successful operation of Shisanling earthquake precursory system proved that the mode of VPN plus CDMA in the establishment of network for an earthquake precursory observing system can be done with less investment and the advantages of quick effective and reliable data transmission could be widely applied.
