Abstract

The invention relates to the technical field of photovoltaic module cleaning, and discloses an intelligent control method of a photovoltaic module cleaning robot. The method comprises the steps: S1, setting an image acquisition module which comprises an image collector arranged on one side of a photovoltaic module, wherein the image collector collects an image of the photovoltaic module in a clean state, takes the image as an initial image, and intermittently acquires a set of reference images by an image collector; S2, calculating the dust accumulation degree; S3, calculating the similarity; S4, determining a cleaning area. Whether the whole photovoltaic module needs to be cleaned or not can be preliminarily judged, control is carried out from a large direction, control steps are reduced, efficiency is improved, the cleaning states of all photovoltaic modules in the photovoltaic module area can be considered, the accuracy of photovoltaic module cleaning judgment is improved, and cleaning can be conveniently carried out for different areas.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module cleaning, in particular to an intelligent control method for a photovoltaic module cleaning robot. Background technique [0002] Photovoltaic modules are exposed to the air for a long time, and dust is easy to deposit on the surface of photovoltaic modules, resulting in a decrease in the intensity of light received by the surface of the modules, resulting in a decrease in the output power of the modules, and ultimately reducing the power generation of the photovoltaic power plant. According to relevant data and existing research, long-term dust accumulation can reduce the peak output power of photovoltaic modules by up to about 40%. In order to reduce the impact of dust covering photovoltaic modules and reducing power generation, the modules need to be cleaned irregularly. . [0003] At present, by determining the cleanliness of one of the photovoltaic modules in the photovoltaic powe...
