Hard Suspension Fluxgate Magnetic Measurement System Mounted on Unmanned Rotorcraft

Abstract

The invention discloses a hard suspension type magnetic flux door magnetic testing system on an unmanned gyroplane, and the system comprises an undercarriage, a magnetic flux door sensor and a magnetic flux door gatherer; the magnetic flux door gatherer is set on the unmanned gyroplane for exploration; the magnetic flux door sensor is set on the undercarriage; the magnetic flux door sensor and the magnetic flux door gatherer are connected by wireless signals; the undercarriage comprises multiple connecting pieces and connecting rods; the connecting rods form a framework structure through the connecting pieces. Compared with traditional material, material adopted by the system enables the weight of the system to be reduced; the magnetic interference problem in a data acquisition system is solved; the relative position of the gatherer and the sensor is made to be unique; the flight safety is guaranteed; the sensor extends out of the gyroplane to the maximum extent and is not influenced from outside wind power; the sensor won't be blown onto the rotors of the gyroplane and then will not cause a crash danger; the check and maintenance workload is little; influence by artificial factors is reduced in the most possible way; and the system can work long and stably.

Description

technical field [0001] The invention mainly relates to the technical field of aeromagnetic prospecting, in particular to a hard-suspended fluxgate magnetic measuring system mounted on an unmanned rotorcraft. Background technique [0002] Airborne geophysical prospecting is a kind of geophysical prospecting method. It is a geophysical prospecting method that detects the changes of various geophysical fields during the voyage through the special geophysical prospecting instruments equipped on the aircraft, and studies and searches for underground geological structures and minerals. Aeromagnetic prospecting is a relatively mature prospecting method at present. In the past, large-scale manned aircrafts were mostly used for work. The flying altitude is above 1000 meters. The accuracy of area work is relatively uniform, and it can work in some areas with difficult terrain conditions. In particular, the development of automatic control and electronic computing technology has made...
