General Packet Radio Service(GPRS) technology and its application in geological hazard monitoring

Geological disasters frequently occur in China.The monitoring of geological hazard is a key task for disaster prevention.However,It is dangerons for technical staff to monitor on site.According to the present monitoring technique,it is possible to develop long distance telecontrol,telemeter and 2-way transmission of data using network communication.This new technique may make the engineers and policy-makers real-time analyze the disaster development,and through the monitoring network,we can also give a quick feedback to monitoring station.The auto-telemetry monitoring system can be built by the application of General Packet Radio Service technology(GPRS) in monitoring of geological hazard.In this paper,principles of the GPRS technology are introduced,and its application in the monitoring of geological hazard is demonstrated.
