    • A power-saving infrared-detecting receiving system composed of a micro-controller serving as a main control unit of the receiving system, an infrared module powered through the micro-controller for receiving a modulated infrared signal emitted by a remote controller used together with the receiving system, and an ultra-low power-consuming and independently powered predetector For detecting a low-frequency infrared front guide signal emitted by the remote controller. The receiving system is normally in a standby state in which only a very low power is consumed by the predetector to detect the infrared front guide signal emitted by the remote control for triggering the micro-controller. When the micro-controller is triggered, the receiving system enters into an operational state and sufficient current is supplied to the infrared module for it to receive a complete modulated infrared signal emitted by the remote controller.
    • 一种由作为接收系统的主控制单元的微控制器构成的省电红外线检测接收系统,通过微控制器供电的红外线模块,用于接收与遥控器一起发射的调制红外信号, 接收系统和超低功耗,独立供电的预检测器用于检测由遥控器发出的低频红外前导引信号。 接收系统通常处于待机状态,其中只有非常低的功率被预先检测器消耗以检测由遥控器发射的用于触发微控制器的红外前导引信号。 当微控制器被触发时,接收系统进入操作状态,并向红外模块提供足够的电流,以接收由遥控器发出的完整调制红外信号。
