Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle inspection, in particular to an automatic inspection system of an unmanned aerial vehicle for power transmission and distribution lines. Background technique [0002] Electricity can be seen everywhere in life. Without electricity, people will have difficulty walking. Electricity is mainly transmitted through wires, also called transmission and distribution lines. After the power station produces electricity, the voltage is raised through the transformer, and then sent to the transmission and distribution lines for power transmission. [0003] Transmission lines will be affected by many factors, such as bad weather and bird nesting, which will affect the safety of transmission and distribution lines. Therefore, inspections of transmission and distribution lines are required. Traditional inspections of transmission lines mostly rely on the naked eye or handheld of operation and maint...

Problems solved by technology

[0003] Transmission lines will be affected by many factors, such as bad weather and bird nesting, which will affect the safety of transmission and distribution lines. Therefore, inspections of transmission and distribution lines are required. Traditional inspections of transmission lines mostly rely on the naked eye or handheld of operation and maintenance personnel. The instrument checks the faults in the circuit and judges potential hidden dangers based on experience. However, purely relying on human inspection itself is a huge hidden danger. Safety issues may cause accidents, lead to large-scale paralysis, and cause huge economic losses; sometimes in bad weather such as rain and snow, human inspection is even more difficult. In recent years, drone technology has become more mature, and the power industry has begun Using drones to inspect power lines in large areas, drones have become the best tool for inspectors to complete inspections efficiently and safely

However, in the actual transmission line UAV inspection application, a large number of personnel are required to control the UAV to the job site and manually control the UAV to perform the inspection task, and the level of staff control directly determines whether the inspection quality is up to standard. At the same time, transmission line Most of them are located in the sparsely populated suburbs, far away from the city center. The difficulty of inspection and high quality requirements make fewer and fewer people willing to engage in inspection work; most of the drone inspection operations do not have supporting nests and cannot be moved. Only some line defects can be inspected, and after the UAV inspection is completed, manual image defect analysis is still required. According to statistics, more than billions of inspection pictures are generated every year in the inspection of UAV transmission lines in my country. The consumption of human resources is still huge. Therefore, it is necessary to design an efficient and manpower-saving UAV automatic inspection system for power transmission and distribution lines.
