Automatic cleaning method and system for fan blades of wind power plant

The invention relates to the technical field of dust cleaning, in particular to a wind power plant fan blade automatic cleaning method and system.The method comprises the steps that the fan blade surface dust coverage rate is obtained based on the image recognition technology, and the surface dust coverage rate is compared with the standard preset coverage rate; whether the fan blades are cleaned or not is judged according to the comparison result, and the initial cleaning time is set; when it is judged that the fan blade needs to be cleaned, the dust thickness of the fan blade is obtained, a cleaner is selected to be started, and the initial water speed is set; the real-time rotating speed of the fan blade is obtained, the initial water speed is adjusted, and the first water speed is obtained; and acquiring surrounding environment data of the fan blade, correcting the first water speed and the initial cleaning time, and acquiring the final water speed and the final cleaning time. The cleaning efficiency is i
