A method for dynamic detection and sound wave repelling of birds in the air

Abstract

The invention relates to a method for dynamic detection and sound wave repelling of birds in the air, which belongs to the technical field of detection, and comprises the following steps: carrying a radar, a camera, a communication module and an ultrasonic bird repeller on an unmanned aerial vehicle; Whether there is a target in the radiation area of ​​the center of the sphere, once the target is detected, the camera will continuously collect multiple pictures, and transmit the pictures to the background through the communication module; the background will superimpose multiple continuous pictures to calculate whether the movement trend of the target is in a natural falling state If yes, there is no need to process, if not, start the target tracking mode, the UAV tracks the target, and continues to approach the collected pictures, and continues to return to the background, the time interval for collecting pictures is 3-30 seconds; determine whether the target is a bird, if so, Then start the ultrasonic bird repellent to drive the birds out of the controlled space of the airport. If not, there is no need to deal with it and continue to detect. The air cruise of the present invention has flexible detection and more timely and accurate detection of targets.

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.
