Fusion design between beidou satellite communication technology and sliding force remote monitoring warning system

Abstract

At present, the landslide disaster monitoring methods are mainly based on surface displacement monitoring, rock stratum tilt monitoring, rainfall capacity monitoring and so on at home and abroad. However, displacement and tilt are necessary rather than the sufficient conditions to produce landslide, sliding force is necessary and sufficient condition. According to the above principles, sliding force remote monitoring and early warning system based on GSM network communication platform is developed, and has been applied in 9 areas all over the country, which successfully forecasted landslide 3 times, and has achieved remarkable social and economical benefits. However, due to the landslide mostly in remote mountain, GSM network signals are weak and some areas are even in dead zone, in order to further promote the data transmission capacity of the system, according to the comparison among the existing remote data transmission modes, Beidou satellite communication technology is selected as the remote data transmission link of the system, which has no dead zone, low power consumption, and can expand the application fields of sliding force remote monitoring system.
