| Abstract: | In general,geological disaster parameters were transfered by the public network or the cable to remote center.This way that the public network and the cable must be needed limits the erection and application of monitoring instruments.In this paper,we taken monitoring of debris flows disaster for example.Accroding to characteristics of the monitoring of debris flows disaster and blind spots out public network,wireless transmission radios of 336~344 MHz were used to transfer related data collected by debris flows disaster sensors to master station,which exchange data to remote center by public network simultaneously.From this way,the problem is solved that blind spots out public network is difficult to transfer geological disaster data to public network.The Mt.Everest Nature Reserve located in the high altitudes contains a large number of blind spots of public network and geological disasters.Therefore,there were an ideal laboratory for the applications and testing of the system.Finally,through actual test,it is sensible solution that the use of wireless transmission radio extend the public signal to blind spots to monitor geological disaster data. |
