PROCÉDÉ ET APPAREIL D'ALIMENTATION ÉLECTRIQUE POUR INTERFACE USB, ET APPAREIL DE ROUTAGE SANS FIL

USB接口的供电方法、装置及无线路由装置
Abstract:
(EN)
A power supply method and apparatus for a USB interface, and a wireless routing apparatus. The power supply method for a USB interface comprises: increasing the value of a current flowing through a controllable load when a device is connected to a USB interface, wherein the controllable load is connected to the USB interface and configured to adjust the current flowing through the USB interface (S202); using the current value of the current flowing through the controllable load as the loading capacity of the USB interface when it is detected that the voltage value of the USB interface is smaller than the lower limit of a system power supply voltage in the process of increasing the current value (S204); determining whether the loading capacity of the USB interface is greater than a minimum current value required when the device normally operates (S206); and if yes, determining the operating power of the device (S208). The method resolves the problem in the related prior art of abnormal shutdown or restarting caused by differences in loading characteristics between wireless routing apparatuses of different specifications.
(FR)
L'invention concerne un procédé et un appareil d'alimentation électrique pour une interface USB, et un appareil de routage sans fil. Le procédé d'alimentation électrique pour une interface USB consiste : à augmenter la valeur d'un courant circulant à travers une charge pouvant être commandée lorsqu'un dispositif est connecté à une interface USB, la charge pouvant être commandée étant connectée à l'interface USB et configurée pour régler le courant circulant à travers l'interface USB (S202) ; à utiliser la valeur actuelle du courant circulant à travers la charge pouvant être commandée en tant que capacité de chargement de l'interface USB lorsqu'il est détecté que la valeur de tension de l'interface USB est inférieure à la limite inférieure d'une tension d'alimentation de système dans le processus d'augmentation de la valeur de courant (S204) ; à déterminer si la capacité de chargement de l'interface USB est supérieure à une valeur de courant minimale requise lorsque le dispositif fonctionne normalement (S206) ; et si tel est le cas, à déterminer la puissance de fonctionnement du dispositif (S208). Le procédé résout le problème dans l'état de la technique selon lequel un arrêt ou un redémarrage anormal est provoqué par des différences de caractéristiques de chargement entre des appareils de routage sans fil de différentes spécifications.
(ZH)
一种USB接口的供电方法、装置及无线路由装置。其中,USB接口的供电方法包括:当设备接入到USB接口时,增加流经可控负载的电流值,其中,该可控负载与所述USB接口连接,并设置为调整流经所述USB接口的电流(S202);在增加所述电流值的过程中,当检测到所述USB接口的电压值小于系统供电电压的下限值时,将流经所述可控负载的当前电流值作为所述USB接口的带载能力(S204);判断所述USB接口的带载能力是否大于设备正常工作时所需的最小电流值(S206);在判断结果为是的情况下,确定所述设备的工作功率(S208)。该方法解决了相关技术中由于不同规格的无线路由装置之间负载特征的差异,所导致的异常关机或重启问题。
