Abstract

The invention provides an aerial survey device and method for geomagnetic field intensity. The aerial survey device comprises an aero-model helicopter, a magnetometer and a flight control system, wherein, the flight control system comprises an airborne part and a ground station part; and the airborne part is arranged on the aero-model helicopter body and is wirelessly connected with the ground station part. The aerial survey method comprises the following steps: the flight control system transfers flight status data of the aero-model helicopter, geographic and geomorphic photography data and magnetic survey data from the magnetometer to the ground station control system in real time; and the ground station control system controls the flight height and flight path of the aero-model helicopter according to the received data so that the magnetometer can acquire geomagnetic field intensity data. The contour-chasing high-precision magnetic survey device has the advantages of control capabilities for the contour-chasing flight height as well as hovering and low-speed flight, low cost, high safety, convenient carrying procedure, small overall volume, no need of an airport and auxiliary equipment during the takeoff and landing processes, no need of a pilot and the like.

Description

technical field [0001] The invention belongs to the technical field of magnetic measurement, and in particular relates to a device and method for carrying high-precision measurement of the strength of the geomagnetic field, and a flight carrier for realizing geological prospecting, exploration and environmental engineering investigation. Background technique [0002] At present, when geophysical methods and magnetic methods are used to detect the distribution of underground mineral deposits and solve geological problems on land, aerial surveys and ground surveys are generally used. Aerial surveys usually use manned fixed-wing aircraft or helicopters to carry surveyors and equipment for aeromagnetic surveys, which have the advantages of long time in the air, large-scale equipment, high measurement efficiency, regular survey network, and large amount of information. It has played an important role in the exploration of metallogenic belts, providing rich data for regional geolo...
