Photovoltaic power station unmanned aerial vehicle inspection system and method

Abstract

The invention discloses a photovoltaic power station unmanned aerial vehicle inspection system and method in the technical field of unmanned aerial vehicle inspection. The system comprises an inspection unmanned aerial vehicle, an on-site charging station and a control center. According to the invention, multiple groups of on-site charging stations are reasonably distributed in the photovoltaic power station; the unmanned aerial vehicle can select a nearby charging station for charging or storage; the returning flight distance is reduced; the accident probability of the unmanned aerial vehicleis reduced; meanwhile, the cruising inspection efficiency of the unmanned aerial vehicle can be improved to a certain extent; according to the invention, the emergency control module with an emergency self-powered function is arranged in the on-site charging station; when the control center loses control over the unmanned aerial vehicle, the main controller can be replaced in time to take over and control the unmanned aerial vehicle, the unmanned aerial vehicle is controlled to return to a nest at the first time, loss caused by out-of-control flight of the unmanned aerial vehicle is avoided,multiple flight paths are designed with the field charging station as the base point, and the unmanned aerial vehicle inspection path can be more reasonable.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle inspection, in particular to an unmanned aerial vehicle inspection system for a photovoltaic power station. Background technique [0002] Photovoltaic power stations are generally built in remote areas such as deserts, Gobi, and grasslands with open areas and sufficient sunlight. During the operation of power generation, affected by natural environmental factors such as wind, sand, snow, rain, bird droppings, etc., the photovoltaic panels of photovoltaic power plants are susceptible to damage to varying degrees, which affects the power generation efficiency of the power generation system and reduces the working life of the system. Therefore, it is necessary to carry out daily maintenance on photovoltaic panels, find damage and repair it in time. At present, the commonly used maintenance method is manual inspection, which requires inspection personnel to carry equipment to the phot...

AI Technical Summary

Problems solved by technology

[0004] The above system has a UAV hangar in the photovoltaic power station to charge and store the UAV, which can realize the remote inspection and control of the UAV. However, there are still some problems in the above system. In actual situations, the photovoltaic power station generally covers an area of Very large, the number of UAV hangars set up by the above-mentioned system is relatively small. When the UAV encounters an unexpected situation in the middle of the flight or a long distance, such as insufficient power or sudden bad weather, etc., it must fly a long distance at this time The distance to return to the UAV hangar for charging and battery life, the long-distance flight back to the nest is very likely to increase the probability of accidents of the UAV, and the long flight back to the nest will inevitably reduce the detection efficiency; at the same time, the above-mentioned systems also lack Emergency protection system, when the drone management center loses control of the drone due to circuit problems, the drone will fly out of control and cause economic losses
