Abstract

The invention relates to an aeromagnetic measuring device and method based on a fixed-wing unmanned aerial vehicle. The aeromagnetic measuring device comprises the fixed-wing unmanned aerial vehicle, a proton magnetometer and a flight control system. A measuring holder used for installation of the proton magnetometer is fixed to the fixed-wing unmanned aerial vehicle. The proton magnetometer is used for carrying out magnetic measurement in the flying process of the fixed-wing unmanned aerial vehicle, and transmitting the magnetic measurement data to the flight control system. The flight control system is used for collecting flight data of the fixed-wing unmanned aerial vehicle, receiving the magnetic measurement data transmitted by the proton magnetometer, and sending the flight data and the magnetic measurement data to the ground in real time, so that flying control over the fixed-wing unmanned aerial vehicle is achieved on the ground according to the received flight data. The aeromagnetic measuring device and method solve the problems that manned vehicle aeromagnetic measurement is high in operation cost and personnel risk, and ground magnetic measurement is low in operation efficiency, large in environmental disturbance and the like.

Description

technical field [0001] The invention relates to the field of magnetic measurement, in particular to an aeromagnetic measurement device and a measurement method using a fixed-wing unmanned aerial vehicle equipped with a high-precision magnetic measurement instrument. Background technique [0002] As an important branch in the field of geophysical exploration, magnetic measurement is widely used in geological and mineral surveys or exploration. The working method is mainly to carry out area-based geomagnetic field measurement. At present, there are two main modes, airborne magnetic measurement and ground Magnetic measurement. From the perspective of measuring instruments, the aviation magnetometer is mainly based on the optical pump magnetometer, such as the potassium optical pump magnetometer in Canada, the cesium optical pump magnetometer and the helium optical pump magnetometer produced in China. Although the sensitivity of the optical pump magnetometer is high, However, t...
