Aerial magnetic force detection device and aerial magnetic force detection method based on unmanned aerial vehicle

Abstract

The invention relates to an aerial magnetic force detection device and an aerial magnetic force detection method based on an unmanned aerial vehicle. The aerial magnetic force detection device comprises an aerial magnetometer system, an unmanned aerial vehicle flying platform, an onboard data collection system and an onboard GPS (global positioning system). The aerial magnetometer system comprises a total-field magnetometer and a three-component magnetometer, wherein the total-field magnetometer is used for measuring earth magnetic fields and the three-component magnetometer is used for measuring attitudes of the unmanned aerial vehicle. The onboard data collection system comprises a master control module, a total-field magnetometer collection module, a three-component magnetometer collection module, a GPS module, an A / D (analog to digital) collection card, a state display module and a storage module. The aerial magnetic force detection device and the aerial magnetic force detection method have the advantages that large manned aerial vehicles are not needed, aeromagnetic survey cost is reduced, the device and the method are applicable to magnetic force detection of the borderland, where vehicles and ships cannot reach, between land and shallow sea, and low cost, high safety and the like are achieved.

Description

technical field [0001] The invention relates to an aerial magnetic detection device and method based on an unmanned aerial vehicle, belonging to the technical field of geophysical exploration. Background technique [0002] Aeronautical magnetic detection is a method of detecting the geomagnetic field through the magnetometer installed on the aircraft, obtaining the magnetic parameters of the geomagnetic field, and analyzing and judging the geological situation or judging the prospecting target area by calculating and drawing the obtained data . Traditional aeronautical magnetic detection devices need to be used on manned special aircrafts, which have high operating costs and require professional pilots to operate. Due to the limitations of weather, terrain, machinery and other conditions, the safety of personnel is threatened. In addition, the operating time is limited by the night, making it difficult to carry out all-weather operations; the operating area is relatively li...
