Airborne electromagnetic-field measurement probe and UAV

Abstract

The invention discloses an airborne electromagnetic-field measurement probe and a UAV. The airborne electromagnetic-field measurement probe comprises electric-field antennas, magnetic-field antennas,first conditioning modules, second conditioning modules, a converter and a signal processing module; the electric-field antennas are used for receiving electric-field signals, and converting the electric-field signals into alternating current; the magnetic-field antennas are used for receiving magnetic-field signals, and converting the magnetic-field signals into alternating voltage; the first conditioning modules are used for converting alternating current signals into first voltage signals; the second conditioning modules are used for converting alternating current voltage into second voltage signals; the converter is used for transmitting the first voltage signals or the second voltage signals to the signal processing module, and receiving an axial switching instruction sent by the signal processing module; and the signal processing module is used for sequentially gaining, filtering and performing analog-to-digital conversion on the first voltage signals or the second voltage signals. According to the airborne electromagnetic-field measurement probe and the UAV in the invention, the probe is carried on the UAV; positioning is carried out according to the electric-field intensityand the magnetic-field intensity measured by the probe; and thus, obstacles are effectively avoided in the patrol.

Description

technical field [0001] The invention relates to the technical field of transmission line inspection and positioning, in particular to an airborne electromagnetic field measurement probe and an unmanned aerial vehicle. Background technique [0002] Power grid inspection and safety prevention and control are the key supporting technologies to ensure the safe operation of the power system. At present, power line inspection mainly uses manual methods, which is time-consuming and labor-intensive. Although there have been drone inspection trials in some areas, most of these drones use satellite signal positioning and navigation and radar ultrasonic obstacle avoidance, so that in the wild or complex environments In the roadway of the UAV, it is inevitable that the UAV will lose the satellite signal, and the radar ultrasound cannot correctly reflect the position of the thin wire, so that it cannot effectively avoid obstacles and cause navigation failure, and even safety accidents su...
