说明：  单片机采用了当前比较流行的一款AVR 芯片ATMEGA8， 红外摇控器发出的信号被TSOP1738 解调后，传送到单片机I/O 口，单片机按一定时序进行 解码并得到按键代码，根据不同的按键代码控制继电器K1 和K2，实现连接在继电器相应 输出口的电器电源的开通与关断功能。D1 和D2 用于同步指示K1 和K2 的开关状态，Q1 和Q2 分别用于驱动继电器K1 和K2。R4 和C3 构成TSOP1738 供电引脚上的滤波电路，起 到了抗干扰作用。 电
(SCM uses a current popular AVR chip ATMEGA8, infrared remote control signal emitted by TSOP1738 demodulation, the transmitted to the MCU I/O port, single chip to decode a certain timing and get key code, key code according to different control relays K1 and K2, to achieve the appropriate output port connected to the relay' s opening and the electrical power off function. D1 and D2 K1 and K2 used to synchronize the switching instructions state, Q1 and Q2 are used to drive relay K1 and K2. R4, and C3 form TSOP1738 supply pins on the filter circuit, played a role in anti-interference. Electricity)
