UAV inspection system

Abstract

The present invention relates to the field of UAV operation maintenance, and particularly relates to a UAV inspection system. A ground control terminal can carry out two-way communication with a task helicopter which carries out an inspection task through a relay helicopter, thus the functions of image data transmission and the fly control of the task helicopter are realized, and the fly control distance of an UAV is greatly improved. At the same time, according to the technical scheme, a 126cc water-cooled engine is used to the defects of insufficient power, small load capacity and short life of an 80cc engine, a 200W engine and a rectifier filter module are installed according to a vehicle generation principle, the problem of power supply needed by airborne equipment is solved to a certain extent, and on the whole, the UAV inspection system has the advantages of long fly time, long distance operation across mountains and high adaptability.

Description

technical field [0001] The invention relates to the field of operation and maintenance of unmanned aerial vehicles, in particular to an unmanned aerial vehicle inspection system. Background technique [0002] At present, my country's State Grid and China Southern Power Grid have more than 500,000 kilometers of transmission lines above 110 kV. The traditional manual line inspection method can no longer meet the extensive needs of modern power systems, and the birth of UAV line inspection has greatly improved the efficiency of line inspection, especially UAV line inspection is especially suitable for applications in mountainous areas, lakes, mining areas and other areas On the power transmission lines (applicable to other maintenance objects as well), when natural disasters cause roads to be blocked and personnel cannot patrol and inspect, the terrain in these areas is complex, and manual line inspection is time-consuming and inefficient on the road. UAVs can play a substitute...

Problems solved by technology

In practical applications, this indicator is far from being suitable for the main needs of the power grid’s mountainous environment beyond the line of sight. The specific reason is that in the mountainous environment, the wireless communication signal of the UAV inspection system will be attenuated to varying degrees. As a large-scale operation, drones will greatly reduce their operating efficiency if they are restricted by wireless transmission; the main reasons include: 1. The battery life is short, because most of the unmanned helicopter inspection systems use 80cc air-cooled The engine has low horsepower and high cylinder temperature during long-term flight, which affects the life of the engine and has potential safety hazards; 2. The flight control distance is short, because the flight control of the unmanned helicopter inspection system needs to use data transmission and image transmission devices to improve flight control. The control distance is restricted by the size of the unmanned helicopter, and the airborne data transmission and image transmission devices cannot be made very large, which limits the flight control distance of the unmanned helicopter inspection system; 3. Without onboard power generation, it is impossible to provide Sufficient power for airborne equipment, relay equipment is not better used
