Abstract

The invention discloses an unmanned aerial vehicle semi-aviation transient electromagnetic receiving coil flight parameter measuring device and method. The device comprises a receiver, an attitude resolving module, a nine-axis attitude sensor, a GPS, a radar altimeter, a transient electromagnetic receiver and flight quality inspection software. The receiver comprises a receiver shell and an annular receiving coil arranged in the receiver shell, the receiving coil is connected with the bottom of the unmanned aerial vehicle through four anti-torsion ropes, and self-rotation of the coil in the flight process can be effectively reduced. The attitude resolving module, the nine-axis attitude sensor and the GPS are all fixedly arranged at the circle center of the receiving coil; the course angleof the receiving coil can be accurately obtained; the attitude of the receiving coil is calculated in real time, a radar altimeter is fixedly arranged below the circle center of the receiving coil, height information for calculating a vertical magnetic component in the data inversion process can be provided, and flight quality inspection software monitors the flight quality by dynamically playingback flight parameters of the receiving coil on site.

Description

technical field [0001] The invention relates to the field of geophysical transient electromagnetic exploration, in particular to a device and method for measuring flight parameters of a semi-aviational transient electromagnetic receiving coil of an unmanned aerial vehicle. Background technique [0002] The receiving subsystem of the UAV semi-aerial transient electromagnetic survey system is mainly composed of the UAV, the receiving coil suspended under the UAV, and the airborne transient electromagnetic receiver. The commonly used ground transient electromagnetic receiving coil is directly hung under the UAV with ropes, and its shell structure and hanging technology are not suitable for the air flight of the receiving subsystem of the semi-aerial transient electromagnetic survey system. During the working process, due to the influence of turbulent airflow and non-uniform speed in the air and the transmission of the vibration of the UAV body, it is difficult for the receiving...
