Unmanned aerial vehicle cluster ground-air transient electromagnetic measurement method suitable for rapid landslide investigation

Abstract

The invention relates to an unmanned aerial vehicle cluster ground-air transient electromagnetic measurement method suitable for rapid landslide investigation. The method comprises the following steps: step 1, arranging a loop emission frame; step 2, supplying bipolar square waves in a transmitting frame; step 3, building an unmanned aerial vehicle receiving system; step 4, constructing an unmanned aerial vehicle cluster; step 5, setting flight routes of unmanned aerial vehicle cluster members; step 6, enabling unmanned aerial vehicle cluster members to start measurement; step 7, enabling the members of the unmanned aerial vehicle cluster to send the actually measured data containing the GPS position back to the ground receiving master station; step 8, enabling the ground receiving master station to store data returned by each member of the unmanned aerial vehicle cluster; step 9, positioning the returned data in real time; step 10, performing real-time three-dimensional imaging according to the position of each measuring point; and step 11, forming a three-dimensional result by the area scanned by the unmanned aerial vehicle cluster, and clearly displaying the geoelectric structure and range of the landslide mass at the corresponding position. According to the invention, the range of the landslide mass and the geoelectric structure can be rapidly and reliably detected, and a basis is provided for landslide control.

Description

technical field [0001] The invention relates to the technical field of landslide monitoring, in particular to an unmanned aerial vehicle cluster ground-air transient electromagnetic measurement method suitable for rapid landslide investigation. Background technique [0002] my country is one of the countries that suffer from serious geological disasters, among which landslide disasters are the most serious. Quickly obtaining the structural characteristics of landslides is the key to prevention and control. At present, the research on geophysical detection of landslide geological hazards is mainly based on ground geophysical methods. However, mountainous areas with complex terrain usually have ravines and dense vegetation. Conventional ground geophysical methods are limited by complex terrain conditions. In some key landslide structural areas, there are construction difficulties and long data collection cycles, which cannot meet the actual needs of rapid and reliable detectio...
