Dynamic detection and sound wave repelling method for birds in air

Abstract

The invention relates to a dynamic detection and sound wave repelling method for birds in the air, and belongs to the technical field of detection. The dynamic detection and sound wave repelling method comprises the following steps of carrying a radar, a camera, a communication module and an ultrasonic bird repeller on an unmanned aerial vehicle; using the radar for continuously monitoring whethera target exists in a radiation area with the unmanned aerial vehicle as the sphere center or not, and once the target is monitored, using the camera for continuously collecting multiple pictures, andusing the communication module for transmitting the pictures to a background; using the background for superposing the plurality of continuous pictures, calculating whether a motion trend of the target is in a natural falling state or not, needing no treatment if yes, starting a target tracking mode if not, tracking the target by the unmanned aerial vehicle, continuously getting close to the target for acquiring pictures, and continuously returning the pictures to the background, wherein the time interval of the acquired pictures is 3-30 seconds; and judging whether the target is the bird ornot, if yes, starting the ultrasonic bird repeller to repel the bird out of an airport management and control space, and if not, continuing detection without treatment. According to the dynamic detection and sound wave repelling method, aerial patrol and detection are flexible, and target discovery is more timely and accurate.

Description

technical field [0001] The invention relates to a method for dynamic detection and sound wave repelling of birds in the air, belonging to the technical field of detection. Background technique [0002] Collision between aircraft and birds is a worldwide problem, which poses a threat to the flight safety of civil aviation aircraft and military aircraft. Airplanes are afraid of birds because the relative speed of the aircraft is high, and the force after colliding with an object will be great. If the bearing capacity of a certain part of the aircraft is exceeded, the aircraft body or parts may be damaged, and the flight safety will be directly threatened in serious cases. [0003] Therefore, it is necessary to monitor the birds in the air around the airport at any time to prevent the birds from colliding with the plane during take-off or landing. However, there are about 20,000 bird-colliding accidents in the world every year, which cause about 950 million US dollars in losses...

AI Technical Summary

Problems solved by technology

[0004] At present, the low- and medium-altitude birds near the airport are mainly monitored by radar. Radar monitoring has an obvious fatal disadvantage, that is, when the aircraft passes by, it interferes a lot with the radar, because the positioning system and communication system prepared by the aircraft, as well as the powerful surrounding monitoring The system will shield the radar, causing the radar to fail temporarily. However, during the failure period, the plane just passed by, which is equal to the state of zero control of the birds, resulting in the fact that the birds hit the plane and cannot be effectively controlled.
