Power frequency electromagnetic field probe, power line inspection UAV navigation device and method

Abstract

The present invention provides a power frequency electromagnetic field probe, a navigation device and method for a power line inspection UAV. The probe is set on the UAV used for line inspection of AC power lines. There are magnetic field sensors, and the four adjacent sides of the first side are equipped with electric field sensors; the inside of the probe is equipped with a processing module; the magnetic field sensor measures the power frequency magnetic field strength at the position of the first side during the rotation of the UAV. value; the electric field sensor measures the power frequency electric field strength value at the position of the four adjacent sides of the first side during the UAV line inspection flight; the processing module sends the power frequency magnetic field strength value and the power frequency electric field strength value to the wireless The man-machine control module enables the control module to determine the direction of the AC power line and the position of the UAV relative to the AC power line. In the absence of satellite navigation signals, the power line patrol navigation of UAVs is realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle navigation, in particular to a power frequency electromagnetic field probe, a navigation device and method for an electric power line inspection unmanned aerial vehicle. Background technique [0002] UAV navigation technology is usually based on GPS or Beidou navigation system. The navigation receiving module carried by the UAV receives the signal of space satellite navigation, thereby identifying and positioning its own position, and proceeding according to the designed waypoints and routes. navigation. [0003] At present, in the field of electric power inspection, unmanned aerial vehicles can be used to inspect AC power lines, that is, let unmanned aerial vehicles fly along overhead power transmission lines, and collect images and other information during the flight. However, in some places, due to the harsh environment or Due to weather conditions, there may be poor satellite ...
