Abstract

The invention provides a solar cell assembly hot spot monitoring system based on an unmanned plane. The system comprises a flight control unit, an image acquisition unit, a main control unit and a temperature acquisition unit, wherein the image acquisition unit acquires solar panel image information and determines whether a fouling area exceeds a certain portion scope value, the temperature acquisition unit acquires solar panel temperature information and determines whether there is a local high temperature of a solar panel, and when the fouling area exceeds the preset portion threshold and the temperature information exceeds a preset temperature threshold, it is determined that a hot spot effect occurs; and the main control unit controls the unmanned plane to remain suspended high above the solar panel through the flight control unit, such that the hot spot effect monitoring accuracy can be improved, wrong reporting is prevented, the position of the solar panel with the hot spot effect can be found timely, a risk can be rapidly positioned, and the service life of the solar panel is substantially prolonged. Besides, the invention also provides a solar cell assembly hot spot monitoring method based on unmanned plane.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle-based solar cell module hot spot monitoring system and method. Background technique [0002] Photovoltaic power station solar cell modules are usually installed in open areas and sunny areas. In long-term use, it is inevitable to fall on shelters such as bird excrement, floating soil, fallen leaves, etc. These shelters form shadows on the solar cell components. Due to the existence of partial shadows, the current and voltage of some single cells in the solar cell module have changed. It will cause the product of the local current and voltage of the solar cell module to increase, thereby causing a local temperature rise on the solar cell module. Defects of some cell monoliths in the solar cell module may also cause local heating of the module during operation. This phenomenon is called "hot spot effect". [0003] Existing large-scale power stations are generally built in remote areas in the west, an...
