[0030] The signal receiving module is constructed based on the infrared receiving head IR, is used for receiving the infrared light signal emitted from the external infrared remote controller, and converts the infrared light signal into a digital electric signal;
[0031] The first MCU module is electrically connected with the signal receiving module, and is configured to receive and analyze the digital electrical signal to obtain an analysis result, and output a control signal according to a preset scheme based on the analysis result;
[0032] The control output module is electrically connected with the first MCU module, and is configured to receive the control signal and control the on-off of the load according to the control signal.
[0033] The power supply module is electrically connected with the signal receiving module, the first MCU module and the control output module respectively, and provides stable direct current input for the modules.
[0034] In the embodiment 1, the load can be controlled non-contactly by receiving the infrared signal emitted by the infrared remote controller, and the whole control circuit has simple structure and stable control effect, and is convenient for use.
[0035] The infrared receiving head IR is a three-pin element (VCC, GND, OUT) integrated with a receiving tube, an amplifier, a band-pass filter and a demodulator, which only responds to infrared carrier signals of a specific frequency (usually 38 kHz), can effectively suppress environmental light interference, and after receiving the effective infrared signal, the output end (OUT) will filter out the modulated carrier and directly output the original digital coded signal (a series of high and low level pulses) and transmit it to the main control chip U1.

[0037] In the preferred embodiment, the rectifier bridge jointly formed by the diodes D1, D2, D3 and D4 can convert the DC input into pulsating direct current, and can prevent adverse effects caused by reverse connection of the input power supply, in addition, the pulsating direct current is preliminarily filtered by the large-capacity electrolytic capacitor C1 to smooth the voltage waveform, the voltage stabilizing diode cooperates with the resistor R1 to clamp the voltage at a stable value (such as 5V or 3.3V), so as to ensure that the subsequent chips and components will not be damaged due to overvoltage, and the capacitor CE1 is arranged at the power supply pin close to the chip U1, and is used for filtering high-frequency noise to provide pure power supply for the chip.
