Abstract
(EN) Disclosed is a standby control circuit and operation method therefor, and a playback device. The standby control circuit comprises a controller and a standby power supply. The controller is used for sending a power-on signal to enable a playback device to be in a power-on state, and further used for sending a standby signal to enable the playback device to be in a standby state. The standby power supply is used for supplying power to a microcontroller unit of the playback device when the playback device is in the power-on state and for stopping supplying power to the microcontroller unit of the playback device when the playback device is in the standby state. Therefore, the standby power supply provided in the present invention implements zero power consumption in the standby state, thereby avoiding unnecessary energy waste and improving the energy use efficiency.
(FR) L'invention concerne un circuit de commande de veille et son procédé d'exploitation, et un dispositif de lecture. Le circuit de commande de veille comporte une commande et une alimentation électrique de veille. La commande est utilisée pour envoyer un signal de mise sous tension afin de permettre à un dispositif de lecture d'être dans un état de mise sous tension, et est utilisée en outre pour envoyer un signal de veille afin de permettre au dispositif de lecture d'être dans un état de veille. L'alimentation électrique de veille est utilisée pour alimenter une unité de microcontrôleur du dispositif de lecture lorsque le dispositif de lecture se trouve dans l'état de mise sous tension et pour cesser d'alimenter l'unité de microcontrôleur du dispositif de lecture lorsque le dispositif de lecture se trouve dans l'état de veille. Par conséquent, l'alimentation électrique de veille décrite dans la présente invention réalise une consommation énergétique nulle dans l'état de veille, évitant ainsi un gaspillage superflu d'énergie et améliorant le rendement d'utilisation de l'énergie.
(ZH) 本发明公开了一种待机控制电路及其工作方法、播放设备,所述待机控制电路包括控制器和待机电源,所述控制器用于发出开机信号,以使播放设备处于开机状态,所述控制器还用于发出待机信号,以使播放设备处于待机状态,所述待机电源用于在播放设备处于开机状态时向播放设备的微控制单元供电以及在播放设备处于待机状态时停止向播放设备的微控制单元供电。因此,本发明提供的待机电源在待机状态时的功耗为零,从而避免了不必要的能源浪费,提高了能源的利用效率。
