APPLICATION OF VPN TECHNOLOGY IN GEOMAGNETISM ARRAY OF XINJIANG

The observation sites distribution,device constitution in the observation sites of Xinjiang geomagnetism array,access situation of geomagnetism array observation system to earthquake backbone network with VPN technology were introduced.The application of VPN technology in Xinjiang geomagnetism array realized the remote management and data exchange of geomagnetism array device by earthquake backbone network,receiving data information at any moment,and fast tracking short-term and impending change of observation data before and after earthquakes.
