Research On Monitoring System Of Landslides Based On ZigBee And BDS/GPS Dual-network Positioning

Landslide disaster in China is a common geological disaster,due to landslides caused by the loss is huge.The occurrence of landslides is not only a serious threat to people's lives,property safety,while the environment,ecological species,resources and other aspects of causing great damage.According to the Geological Hazard Report published by China Geological Environment Information Network,there were 260778 geologic disasters in the country between 2006 and 2015,among which the proportion of landslide occurred at a total of 192408,accounting for the total number of geological disasters 73.78%,living in the first geological disaster.This decade caused by landslides caused by casualties,missing a total of 11,281 people,resulting in direct economic losses of more than 43.5 billion yuan.The secondary disasters caused by landslides also cause serious losses.Therefore,it is of great significance to take the necessary monitoring means,and then to make scientific,rapid and efficient forecasting and forecasting of landslide disasters.In the field of landslide monitoring system,ZigBee technology,China's Beidou satellite navigation system(BDS),global positioning system(GPS)technology development,making ZigBee and BDS/GPS technology in the landslide monitoring has a wide range of applications Prospects,and thus landslide monitoring technology research is a hot spot.Due to the many factors influencing the development of landslide(such as human engineering activities,topography,geological structure,etc.),the landslide movement has the characteristics of uncertainty,complexity and openness.The traditional method is difficult to make accurate Forecasting.Based on the basic positioning principle of global satellite navigation system(GNSS),this paper expatiates the technology of ZigBee and BDS/GPS dual network positioning to monitor the mountainous landslide monitoring system based on ZigBee and BDS/GPS dual network positioning.The feasibility of landslide,the use of differential algorithm to improve the positioning accuracy.The main research contents and research results are as follows:(1)The landslide monitoring system proposed in this paper is based on the combination of ZigBee and BDS/GPS,and analyzes the error sources of positioning accuracy.(2)To determine the composition of the landslide monitoring system and hardware equipment and experimental analysis.(3)Mountain landslide test,analysis of landslide monitoring data.
