Embodiment Construction

[0028] Under normal circumstances, the failure of the photovoltaic panel will affect its own power generation, which will cause a short circuit in some areas of the photovoltaic panel and increase the current value. Excessive current will generate higher heat, which is reflected in the temperature of the board surface. By analyzing the thermal image taken by the infrared camera, the specific location of the fault can be obtained, and the UAV can be controlled to fly to the location of the fault. Visible light images are taken from above to effectively identify the type of fault.

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0030] Such as figure 1 As shown, the present invention is based on the UAV-based photovoltaic array inspection method, which includes two parts: the UAV and the ground control station. The processor is responsible for path planning and control, and is also responsible for the communicatio...

Abstract

The invention discloses a photovoltaic array inspection method based on an unmanned aerial vehicle. In the method, the unmanned aerial vehicle is taken as a platform, and a high flexibility characteristic of the unmanned aerial vehicle is used so as to realize fault inspection of the unmanned aerial vehicle to a photovoltaic plate in a photovoltaic power station under a complex geographic environment. The unmanned aerial vehicle is carried with a high performance processor and two kinds of cameras (a visible light camera and an infrared camera), and simultaneously is carried with an accelerometer, a gyroscope, a magnetic induction meter and a GPS module. During an operation process, a GPS/SINS algorithm is used to calculate an outdoor flight position of the unmanned aerial vehicle so as to realize flight path control of the unmanned aerial vehicle. An image shot by the infrared camera is used to position a fault, and the visible light camera is used to carry out detailed shooting on the fault and return to a ground station so as to carry out subsequent processing. In the invention, autonomous inspection of the unmanned aerial vehicle to a photovoltaic array in the photovoltaic power station is realized so that usage of manpower and material resources is effectively reduced; and simultaneously because of flexibility of the unmanned aerial vehicle, photovoltaic array inspection under a complex environment becomes fast and high-efficient.

Description

technical field [0001] The invention relates to the field of photovoltaic array fault detection, in particular to a method for patrolling and inspecting a photovoltaic array based on an unmanned aerial vehicle. Background technique [0002] my country's solar energy resources are very rich, and the potential for development and utilization is very broad. This year, my country's demand for energy is increasing day by day, and the pressure on environmental protection is increasing. The issue of solar photovoltaic power generation in China has received widespread attention. At the same time, more and more photovoltaic power stations have been built and put into use. Due to its power generation characteristics, photovoltaic power stations have huge areas and a large number of photovoltaic panels. The current fault inspection method mainly uses manual inspection operations, which is labor-intensive and low in efficiency. In addition, many photovoltaic power stations are currentl...
