Problems solved by technology

[0002] During the flight, the plane is most afraid of encountering birds, because flying at high speed, if it hits a bird, it is easy to damage the plane, or even more serious consequences
Therefore, bird repelling devices are usually provided at airports to drive away birds. Existing bird repelling devices are mainly two ways of sound wave repelling birds and laser repelling birds. It is suitable for low-altitude bird repellent; while the laser bird repellent device is only suitable for cloudy days and nights, and has higher requirements for weather conditions

Abstract

The invention discloses an acousto-optic bird repellent device comprising a signal processing and control circuit, and an orientation sound wave bird repellent unit and a laser bird repellent unit which are connected with the signal processing and control circuit. The orientation sound wave bird repellent unit comprises a low-pass filter circuit, an A / D conversion circuit, a D / A conversion circuit, a power amplification filter circuit and an energy transducer set, wherein the low-pass filter circuit is connected with the A / D conversion circuit, and the D / A conversion circuit, the power amplification filter circuit and the energy transducer set are connected in order, the low-pass filter circuit is connected with an input audio signal, the A / D conversion circuit is connected with an input terminal of the signal processing and control circuit, an output terminal of the signal processing and control circuit is connected with the D / A conversion circuit, and the energy transducer set outputs an orientation audio signal. Orientation sound wave and laser are combined in the acousto-optic bird repellent device, and the acousto-optic bird repellent device can be used for driving high-altitude birds away with low noise pollution.

Description

technical field [0001] The invention belongs to the technical field of bird repelling devices, and in particular relates to an acousto-optic bird repelling device. Background technique [0002] During the flight, the aircraft is most afraid of encountering birds, because flying at high speed, if it hits a bird, it is easy to damage the aircraft, or even have more serious consequences. Therefore, bird repelling devices are usually provided at airports to drive away birds. Existing bird repelling devices are mainly two ways of sound wave repelling birds and laser repelling birds. It is suitable for low-altitude bird repelling; while the laser bird repelling device is only suitable for cloudy days and nights, and has higher requirements for weather conditions. Contents of the invention [0003] The purpose of the present invention is to provide an acousto-optic bird-repelling device for the problems existing in the above-mentioned existing bird-repelling devices, which uses ...
