Distributed space synthesis sound wave array bird repelling device and equipment

Abstract

The invention discloses a distributed space synthesis sound wave array bird repelling device and equipment. The device is characterized in that a communication device receives position information ofa sound source and position information of auditory organisms such as birds, and transmits the position information of the sound source and play delay, phase and sound intensity control information ofan audio space synthesis control device to a sound production terminal; and the audio space synthesis control device receives the position information of the sound source and the position informationof the auditory organisms such as the birds, processes the position information associated with the sound source and the predicted synthesis space position, and controls the playing delay, phase andsound intensity of the sound production terminal, and the sound production terminal also plays processed sound waves, so that it is ensured that the controlled sound waves are spatially synthesized atthe position of the auditory organisms such as the birds, the maximum sound intensity is achieved, the intensity of the synthesized sound waves is not limited by the sound wave intensity critical value near the sound source, the auditory organisms such as the birds are repelled, and long-distance repelling of the auditory organisms such as the birds can be achieved.

Description

technical field [0001] The invention relates to the technical field of bird repelling, in particular to a distributed spatial synthetic sound wave array bird repelling device and equipment. Background technique [0002] Bird strikes are a major source of danger faced by aircraft, and civil aviation and military aviation airports have invested a lot of material and manpower in bird repelling business. [0003] Existing bird repelling schemes generally adopt methods such as sonic bird repelling, laser bird repelling, bird repelling nets, and bird repelling agents. Among them, the sonic bird repelling technology is widely used because of its simple use and small secondary hazards. Frighten and drive away with natural enemy-like sounds or sounds that make them uncomfortable. The sound of natural enemies of birds is used. Due to the strong adaptability of birds, the performance of the sonic bird repellent device at the airport drops significantly after a period of operation. Alt...

AI Technical Summary

Problems solved by technology

The sound of natural enemies of birds is used. Due to the strong adaptability of birds, the performance of the sonic bird repellent device at the airport drops significantly after a period of operation. Although the sonic bird repellent device can use the discomfort to drive away the birds, it needs to be maintained. Larger sound intensity, for example, the sound intensity needs to be greater than 120dB (decibel, decibel). Acoustic equipment usually uses an array composed of multiple speakers to produce it through beam synthesis. For acoustic equipment, 194dB is the critical sound wave intensity in the air. When th
