Power frequency electromagnetic field probe and power line patrol unmanned aerial vehicle navigation device and method

Abstract

The invention provides a power frequency electromagnetic field probe and a power line patrol unmanned aerial vehicle navigation device and method, the probe is arranged on an unmanned aerial vehicle for patrol of an alternating current power line, the probe is cuboid, a magnetic field sensor is arranged on a first side surface of the probe, and electric field sensors are arranged on four adjacentside surfaces of the first side surface; a processing module is arranged in the probe; the magnetic field sensor measures the power frequency magnetic field intensity value of the position where the first side face is located in the unmanned aerial vehicle line patrol rotating process; the electric field sensors measure the power frequency electric field intensity values of the positions of the four adjacent side surfaces of the first side surface in the line patrol flight process of the unmanned aerial vehicle; and the processing module sends the power-frequency magnetic field intensity valueand the power-frequency electric field intensity value to a control module of the unmanned aerial vehicle, so that the control module determines the trend of the alternating-current power line and the position of the unmanned aerial vehicle relative to the alternating-current power line. Under the condition that satellite navigation signals are lost, power line patrol navigation of the unmanned aerial vehicle is achieved.

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 ...
