Abstract

The invention provides an unmanned aerial vehicle (UAV) detection system based on embedded audio recognition. The system is characterized by comprising a UAV flight voice template recognition library, an audio acquisition module, an intelligent audio recognition module, and an intelligent alarm module. The system provided by the invention can detect an illegal UAV in real time and promptly notify the security personnel to conduct corresponding security work. The system has the advantages of high recognition rate, stable performance, easy use, low cost, simple maintenance, and the like. An efficient solution is provided for the problem of UAV abuse.

Description

technical field [0001] The invention relates to an identification system capable of accurately identifying the sound of propeller rotation emitted by illegal drones in a noisy environment. Background technique [0002] As consumer-grade drones enter the public eye, discussions on the safety and regulation of drone use in society have never stopped. Due to the particularity of drones, it can pass through obstacles on the ground to reach some artificially blocked spaces, and can carry cameras, weapons, toxic chemicals and explosives, and may be widely used in terrorist attacks, espionage and smuggling Activity. In order to prevent criminals or terrorists from using drones to carry out criminal or terrorist activities, it is necessary to detect such illegal drones. [0003] The existing UAV detection methods include full electric scanning radar technology. This solution can effectively detect large military UAVs and is used in military armed forces. However, this solution has...
