Title
(EN) METHOD FOR DETERMINING ALCOHOL USE BY COMPARISON OF FREQUENCY FRAME OF DIFFERENCE SIGNAL, AND RECORDING MEDIUM AND DEVICE FOR IMPLEMENTING SAME
(FR) PROCÉDÉ DESTINÉ À LA DÉTERMINATION DE LA CONSOMMATION D’ALCOOL PAR COMPARAISON DE LA TRAME DE FRÉQUENCE DE SIGNAL DE DIFFÉRENCE ET SUPPORT D’ENREGISTREMENT ET DISPOSITIF DESTINÉS À SA MISE EN ŒUVRE

Abstract
(EN) This method for determining alcohol use comprises the steps of: detecting an effective frame in an input audio signal; detecting a difference signal in the original signal of the effective frame; performing a fast Fourier transform on the original signal and the difference signal; and determining the state of alcohol use on the basis of a gradient difference between the original signal and the difference signal, which have been subjected to the fast Fourier transform and are in a frequency domain. Accordingly, the present invention can identify the state and extent of alcohol use by a driver or an operator at a long distance and thus can prevent accidents caused by driving or operating under the influence of alcohol.
(FR) La présente invention concerne un procédé destiné à la détermination de la consommation d'alcool qui comprend les étapes consistant à : détecter une trame effective dans un signal audio d'entrée ; détecter un signal de différence dans le signal d'origine de la trame effective ; effectuer une transformée de Fourier rapide sur le signal d'origine et le signal de différence ; et déterminer l'état de consommation d'alcool en fonction d'une différence de gradient entre le signal d'origine et le signal de différence, qui ont été soumis à la transformée de Fourier rapide et sont dans un domaine de fréquence. Par conséquent, la présente invention peut identifier l'état et l'étendue de la consommation d'alcool par un conducteur ou un opérateur à une longue distance et peut ainsi empêcher les accidents causés par la conduite ou l'opération sous l'influence de l'alcool.
(KO) 음주 판별 방법은, 입력된 음성 신호의 유효 프레임을 검출하는 단계; 유효 프레임의 원신호의 차신호를 검출하는 단계; 원신호와 차신호 각각의 고속 푸리에 변환을 수행하는 단계; 및 고속 푸리에 변환된 원신호와 고속 푸리에 변환된 차신호의 주파수 영역에서의 기울기 차이에 기초하여 음주 상태를 판단하는 단계를 포함한다. 이에 따라, 원거리에 있는 운전자 또는 운항자의 음주 여부 및 정도를 파악할 수 있으므로, 음주 운전 또는 운항으로 인한 사고를 예방할 수 있다.
