AN AUTOMATIC CLEANING METHOD FOR PHOTOVOLTAIC MODULE

The present invention discloses an automatic cleaning method for photovoltaic module, which relates to the technical field of photovoltaic cleaning. The method comprises the following steps: S1. Obtaining the environmental data of the photovoltaic module; S2. Judging the threshold of the environmental data and controlling the ON of the cleaning device according to the judgement results; S3. Controlling the ON of the cleaning device through a cleaning control signal ON command and cleaning the photovoltaic module; S4. Collecting the muddy water produced after photovoltaic module cleaning through a muddy water runner connected with a muddy water collecting device; S5. Obtaining real-time water quality images of the muddy water through an underwater camera; S6. Inputting the real-time water quality image into a second neural network module to predict the turbidity of the muddy water; S7. Sending a cleaning control signal OFF command to the cleaning device according to the threshold judgement result of the processor; S8. Turning off the cleaning device through a cleaning control signal OFF command. The present invention realizes intelligent turning off the photovoltaic module by detecting the turbidity of the muddy water through an underwater camera and a neural network module mounted on it.
