| Summary: | The invention provides a method and device for monitoring the overspeed of the rotating speed of a main shaft of a wind turbine generator based on videos, and the method comprises the steps: collecting video images, collecting the images, preprocessing the images, transmitting the preprocessed images to a main control system, monitoring the video images, reading the images, and detecting the read images. The main shaft rotating speed value monitored through the video image is compared with the overspeed value of the main shaft rotating speed of the wind turbine unit, the comparison result is analyzed, analysis is conducted according to the result of the main shaft rotating speed comparison, corresponding operation is conducted through a main control system, the problem of overspeed shutdown of the wind turbine unit is solved, and the working stability is improved; and the generating capacity is improved.
