The infrared remote control system generally consists of a transmitter and a receiver.The transmitter consists of a control key, a control signal generation circuit, a modulation circuit, a drive circuit and an infrared transmitter. When the control key is pressed, the control signal generation circuit generates the required control signal. After the control command signal is modulated by the modulation circuit, the infrared transmitter is finally driven by the control circuit to send an infrared remote control command signal.The receiver consists of an infrared receiving device, a preamplifier circuit, a demodulation circuit, a control signal detection circuit, a memory and a control circuit, and d 'an execution circuit. When the infrared receiving device receives the infrared control signal from the transmitter, the microprocessor recognizes and processes the received signal, and completes the corresponding command to achieve the objective of being controlled.
