Application of monitoring and early warning of geological hazards in mountainous areas based on multi-source data
In this paper,a geological hazard monitoring platform system was established based on BeiDou navigation satellite system(BDS)/global navigation satellite system(GNSS)technology and Internet of things sensor technology.The monitoring data were used to analyze the common geological disasters including debris flow,collapse,and unstable slope.The results show that the BDS/GNSS monitoring accuracy under long-time series monitoring reaches the millimeter level.The real-time monitoring accuracy reaches 2 cm.Combined with multi-source data analysis,an early warning system for multidimensional indicators of geological hazard prevention and control was established,and the data of geological hazards with slow deformation were analyzed,which provided an important reference for geological hazard prevention and control.
