Title
(EN) Standby control circuit, working method of standby control circuit and playing equipment
(ZH) 待机控制电路及其工作方法、播放设备
Abstract
(EN) The invention discloses a standby control circuit, a working method of the standby control circuit and playing equipment. The standby control circuit comprises a controller and a standby power supply; the controller is used for sending a starting signal, so that the playing equipment is in a starting state; the controller is used for sending a standby signal, so that the playing equipment is in a standby state; and the standby power supply is used for supplying power to a micro-control unit of the playing equipment when the playing equipment is in the starting state, and stopping supplying power to the micro-control unit of the playing equipment when the playing equipment is in the standby state. Therefore, the power of the standby power supply provided by the invention is zero in the standby state; therefore, unnecessary energy waste is avoided; and the energy utilization efficiency is increased.
(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,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率为零,从而避免了不必要的能源浪费,提高了能源的利用效率。
