Problems solved by technology

The traditional aeronautical magnetic detection device needs to be used on a manned special aircraft, the operation cost is high, and professional pilots are required to operate it. Restricted by 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 limited, and it is difficult to carry out ocean and island magnetic detection with the survey ship

Embodiment Construction

[0023] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] UAVs are used as the flight movement carrier of the aerial magnetometer and mission system to realize the remote control or autonomous aerial magnetic detection of the system. As a UAV flight platform equipped with a UAV aerial magnetic detection system, it can be divided into two types: fixed-wing UAV and rotary-wing UAV (unmanned helicopter) according to its lift power device.

[0025] The following is a detailed description of the s...

Abstract

The present invention relates to an aerial magnetic detection device and method based on an unmanned aerial vehicle, including an aerial magnetometer system, an unmanned aerial vehicle flight platform, an airborne data acquisition system, and an airborne GPS positioning system; the aerial magnetometer system includes A total field magnetometer for measuring the earth's magnetic field and a three-component magnetometer for measuring the attitude of an unmanned aerial vehicle; the airborne data acquisition system includes a main control module, a total field magnetometer acquisition module, a three-component magnetometer acquisition module, and a GPS module , A / D acquisition card, status display module and storage module. The invention has the advantages of not needing a large manned aircraft, which reduces the cost of aeromagnetic surveying, and is suitable for magnetic surveying in the land where vehicles and ships cannot reach and the border areas of beaches and shallow seas, and has the advantages of low cost and high safety.

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...
