Fixed-wing unmanned aerial vehicle time domain aviation electromagnetic exploration system

Abstract

The invention discloses a fixed-wing unmanned aerial vehicle time domain aviation electromagnetic exploration system. A transmitting system, a receiving system and a recording and monitoring system are additionally arranged on an unmanned aerial vehicle flight platform. The transmitting system comprises a transmitter and a transmitting coil, and the transmitter is installed in the load cabin and used for converting direct current into bipolar combined wave pulse current; the transmitting coil is installed on the unmanned aerial vehicle nose, the unmanned aerial vehicle wings and the unmanned aerial vehicle pelvic fin structure in a closed shape and used for generating a primary electromagnetic field for measurement of the aviation electromagnetic system; the receiving system comprises a receiver nacelle and an electric winch, and the receiver nacelle is installed below the belly of the unmanned aerial vehicle through a receiver nacelle hanging frame and an automatic throwing device, islocated under the load cabin and is used for receiving a secondary electromagnetic field generated by induced eddy current from an underground conductor; the electric winch is mounted below the bellyof the unmanned aerial vehicle through an automatic throwing device, is positioned right ahead the receiver pod and is used for synchronous winding and unwinding and overload shearing of a three-component receiving coil in the receiver pod; and the recording monitoring system is arranged in the load cabin and is used for recording, storing and receiving the data acquired by the receiving system.
