For birds, vision is the most sensitive, especially for green lasers. The automatic laser repellent can run uninterrupted, and in the dawn, dusk, or night without the aircraft's landing and landing, it also continues to shoot the grasslands and runways of the entire airport. For a long time, the ecological environment that affects the survival, inhabitation and foraging of the airport and its nearby birds has caused the birds to gradually generate fear, ultimately away from the airport, and fundamentally prevent and stop the birds from hitting the plane.
