Title (EN) FO DETECTION METHOD AND DEVICE AND SYSTEM THEREFOR
(FR) PROCÉDÉ DE DÉTECTION DE CORPS ÉTRANGER (FO), ET DISPOSITIF ET SYSTÈME ASSOCIÉS
(KO) FO 검출 방법 및 그를 위한 장치 및 시스템
Abstract: front page image
(EN)The present invention relates to a foreign object (FO) detection method for wireless charging, and a device and a system therefor. The FO detection method on a wireless power transmitter, according to one embodiment of the present invention, may comprise the steps of: receiving a second packet comprising a second reference quality factor value; determining a threshold value by using the second reference quality factor value; measuring the current quality factor value; and detecting an FO on the basis of the threshold value and the current quality factor value. Thus, the present invention has the advantage of enabling an FO to be more effectively detected.
(FR)L'invention concerne un procédé de détection de corps étranger (FO) pour charge sans fil, et un dispositif et un système associés. Le procédé de détection de FO sur un émetteur de puissance sans fil, selon un mode de réalisation de l'invention, peut consister: à recevoir un second paquet comprenant une seconde valeur de facteur de qualité de référence; à déterminer une valeur de seuil à l'aide de la seconde valeur de facteur de qualité de référence; à mesurer la valeur de facteur de qualité courante; et à détecter un FO sur la base de la valeur de seuil et de la valeur de facteur de qualité courante. Ainsi, l'invention présente l'avantage de permettre une détection plus efficace d'un FO.
(KO)본 발명은 무선 충전을 위한 FO 검출 방법 및 그를 위한 장치 및 시스템에 관한 것으로서, 본 발명의 일 실시예에 따른 무선 전력 송신기에서의 FO(Foreign Object) 검출 방법은 제2 기준 품질 인자 값이 포함된 제2 패킷을 수신하는 단계와 상기 제2 기준 품질 인자 값을 이용하여 임계치를 결정하는 단계와 현재 품질 인자 값을 측정하는 단계와 상기 임계치와 상기 현재 품질 인자 값에 기반하여 FO를 검출하는 단계를 포함할 수 있다. 따라서, 본 발명은 보다 효과적으로 FO를 검출할 수 있는 장점이 있다.
