Abstract

The invention discloses a transient electromagnetic receiving device for a small multi-rotor low-altitude UAV. The transient electromagnetic receiving device comprises a magnetic signal sensor (1) fixed under a UAV landing gear, a matched resistor (2) and a signal amplifier (3) which are fixed on the magnetic signal sensor (1), a mounting box (4) fixed under a UAV pedestal, ad an analog signal acquisition device (5) and an STM32 development board (6) which are placed in the mounting box (4). The connection relationship is as follows: the magnetic signal sensor (1) is connected in parallel withthe matched resistor (2), and then connected to the analog signal acquisition device (5) by means of a lead wire after passing through the signal amplifier (3); and the analog signal acquisition device (5) is connected to the STM32 development board (6) by means of a signal transmission line. The transient electromagnetic receiving device has the advantages of light weight, high efficiency, goodbalance performance, good stability and wide application range, can complete the ground transient electromagnetic receiving operation efficiently, and can launch operations in paddy fields, houses andsteep regions where ground transient electromagnetic construction cannot be carried out.

Description

technical field [0001] The invention relates to a transient electromagnetic receiving device for a small multi-rotor low-altitude unmanned aerial vehicle, belonging to the technical field of geophysical detection. Background technique [0002] Transient electromagnetic method is a method of geophysical exploration, which uses ungrounded return line or grounding line source to transmit a pulsed magnetic field underground, and uses coils or grounding electrodes to observe the secondary induced eddy current caused in the underground medium during the intermittent period of the pulsed magnetic field. Field, thereby detecting a method of medium resistivity. [0003] Transient electromagnetic method is widely used in engineering survey and mineral exploration and other fields, and can identify karst caves and passages, mine goafs, metal ore bodies, etc. Under normal circumstances, the transient electromagnetic method adopts the working method of ground transmission and ground rec...
