摘　　要：为更好地为西藏地震监测服务,结合虚拟专网技术的发展与VPDN技术的优势,研究将VP⁃DN技术应用于西藏自治区地震网络的方法与可行性。使用了4G无线通讯组网的地震台站,台站端通过无线接入,部署方便、快捷,能够应用在地震监测台站勘选、地震流动观测台网、临时地震监测台网、大震应急流动观测等项目中。且无线网络扩容方便,认证、网管自身一体化,实时掌握所有设备的在线情况,超低的功耗能够降低电源配置的成本和运行维护成本,是目前地震台站实际应用中最具有灵活性和稳定性的数据传输方案。At present,most of the seismic monitoring stations in Tibet still use the traditional telecommunication mobile optical fiber network data transmission method.which corresponds to the technical level of the current construction of stations and the local geographical factors in Tibet has long been unable to adapt.In order to better serve the earthquake monitoring in Tibet,combined with the development of virtual private network technology and the advantages of VPN technology,this paper studies the method and feasibility of applying VPN technology to the earthquake network in Tibet Autonomous Region.The seismic station with 4G wireless communication network is deployed conveniently and quickly through wireless access.It can be applied to the exploration and selection of seismic monitoring stations,seismic mobile observation network,temporary seismic monitoring network,large earthquake emergency mobile observation and other projects.Moreover,the wireless network expansion is convenient,the authentication and network management are integrated,and the online situation of all equipment is mastered in real time.The ultra-low power consumption can reduce the cost of power configuration and operation and maintenance costs.It is the most flexible and stable data transmission scheme in the practical application of seismic stations at present.
