Oriented bird-repelling device and bird-repelling method based on target tracking

Abstract

The invention discloses a directional bird repellent device based on target tracking. The directional bird repellent device comprises a first radar, a holder, a path tracking module, a deflection unit, a frequency corrector, a driving module and a controller, wherein a horn is arranged on the holder; a second radar and a camera are arranged on the horn; the path tracking module calculates the motion path information of a target bird; the deflection unit receives the motion path information and drives the holder to rotate for path tracking to the target bird; the frequency corrector receives the motion velocity of the target bird and generates a correction frequency signal; and the driving module receives the correction frequency signal to correct the driving frequency of the horn. According to the invention, when a bird appears in a detection area, the holder is controlled to track the bird in the whole process, so repellent acoustic wave can target the target bird in real time, and rapidness and effectiveness of repellent are improved; meanwhile, the flying speed of the target bird is monitored in the whole process, and the emission frequency of acoustic wave is adjusted according to the flying speed of the bird, so the acoustic frequency of the position of the bird is guaranteed to exert effective repellent effect to the bird.

Description

technical field [0001] The present invention relates to a bird repelling device, more specifically, the present invention relates to a directional bird repelling device and a bird repelling method based on target tracking. Background technique [0002] With the progress and development of human society, human beings' awareness of the protection of natural ecological environment has been continuously enhanced. Birds, as friends of human beings, have been listed as protection objects. For example, aircraft carriers, aircraft, power grids and other places clearly prohibit bird activities. Since birds cannot distinguish these local areas that will cause serious consequences to human activities, measures are usually taken to drive birds away on the premise of preventing damage to the lives of birds. out of these areas. [0003] At present, most of the devices on the market adopt high-intensity sound waves to drive away birds. However, the disadvantage of this technology is that...

Problems solved by technology

However, the disadvantage of this technology is that the bird repelling device cannot directional drive away the birds, nor can it track the flight path of the birds, making it blind during the bird repelling process; on the other hand, the birds are flying In the process, Doppler efficiency will be generated, which reduces the effect of sound waves on birds, and the frequency of driving away sound waves is not targeted, and the effect of repelling birds is not ideal.
