Unmanned aerial vehicle power line inspection hybrid communication system

Abstract

The invention discloses an unmanned aerial vehicle power line inspection hybrid communication system, which comprises an unmanned aerial vehicle, a relay station, a measurement and control vehicle, a portable communication station and an optical fiber composite overhead ground wire, wherein the relay station comprises an optical fiber wireless relay station and a pure wireless relay station; the optical fiber wireless relay station comprises a relay module integrating a wireless relay module and optical transmission equipment; the wireless relay station comprises the wireless relay module; optical fiber transmission is adopted between the portable communication station and the optical fiber wireless relay station; the portable communication station can establish connection with a wireless module of the measurement and control vehicle by a wireless communication link; and transmission can be performed among the unmanned aerial vehicle, the wireless relay station, the optical fiber wireless relay station and the measurement and control vehicle by the wireless communication link. The unmanned aerial vehicle power line inspection hybrid communication system has the advantages that: the measurement and control distance of the unmanned aerial vehicle can be prolonged to satisfy the needs of unmanned aerial vehicle power line inspection in an over-the-horizon complex environment; and the measurement and control vehicle can finish communication with the unmanned aerial vehicle in a substation without starting for a scene when applied.

Description

technical field [0001] The invention relates to a communication system for electric power, in particular to a hybrid communication system for unmanned aircraft power line inspection. Background technique [0002] The development of unmanned aerial vehicle power line inspection technology has improved the efficiency of line inspection, can detect hidden dangers in time, speed up the response to crisis situations, and reduce labor intensity. However, due to the special operability of unmanned aerial vehicles, the communication of measurement and control data and image data is continuous and reliable, so the terrain on the flight route is required to be open, and the environmental conditions of unmanned aerial vehicles and measurement and control vehicles are in line of sight. However, due to the influence of multipath effect, frequency selective fading and strong electromagnetic interference of transmission lines in wireless communication, especially under special mountainou...

AI Technical Summary

Problems solved by technology

However, due to the influence of multipath effect, frequency selective fading and strong electromagnetic interference of transmission lines in wireless communication, especially under special mountainous conditions, the measurement and control distance is much shorter than the theoretical measurement and control radius of 100km, generally no more than 5km
