The socket circuit is as shown in figure 1. This circuit uses the receiving, amplification, demodulation integrated infrared receiver, the relay triggers the driving circuit to use one piece of dual D flip-flop MC14013, this circuit uses only one channel of it to connect into the bistable form, the D is connected with the Q, the R and S port are connected with the ground. The R3 and C2 RC networks which are connected with the R port have the power-on reset function, so when the power failure comes again, the socket is in the off state. In peacetime, the receiving head output port has the 4.2V high level, T2 is in the conduction state, the bistable circuit trigger input port has the low level, the Q port outputs the low level, T1 cuts off, the relay J stops operating, the socket has no 220V output power. If you press the remote controller again, the receiving head will receive the signal of remote controller, and the output port will output the demodulated pulse signal, so the voltage of the output port reduces, the T2 cuts off, the socket losses the power again.
