Aimed at the problems of the long time and high cost for manual cleaning of aeronautical ground light, an intelligent cleaning system of aeronautical ground light is designed. According to the material of the aeronautical ground lights, electromagnetic sensors are used to sense the lights. The angle adjustable cleaning probe is designed, and the cleaning vehicles is also designed, on which the cleaning probe, light sensors and the drying equipment are loaded. The singlechip microcomputer is used as the controller, and the control flow is given to realize the automatic detection, cleaning and drying of aeronautical ground light.
