Abstract

기존에는 차량도난 방지를 위한 소리종류 인식장치를 제공해 주지 못해 차량도난시 도난차량을 찾기 위해 많은 시간을 낭비해야 하고, 또한 차량의 부속품을 훔쳐가거나, 또는 훔친 부속품을 팔아먹는 등 문제점이 야기되고 있다. 본 발명은 차량도난 방지를 위한 소리종류 인식장치를 제공해 줌으로써 차량도난을 사전에 방지시키도록 하는 데 있다.In the past, it was not possible to provide a sound type recognition device to prevent theft of vehicles, so it was necessary to waste a lot of time to find the stolen vehicle during theft of the vehicle, and also to steal the vehicle's accessories or sell the stolen accessories. . The present invention is to prevent theft of the vehicle in advance by providing a sound type recognition device for preventing theft of the vehicle.
