Application Scheme of Timed Remote Control Fan Chip
The remote control fan mainly consists of a control board, DC motor, offline receiver, remote control, etc. The remote control uses infrared light-emitting diodes to emit modulated infrared light waves. The infrared receiving circuit (on top of the fan) is composed of infrared receiving diodes, transistors, or silicon photocells. They convert the infrared light from the infrared transmitter into corresponding electrical signals, which are then sent to the rear remote control fan chip and sent to the demodulation circuit. The demodulation circuit demodulates the modulated instruction encoded signal and restores it to the encoded signal. Then, the encoded instruction signal is decoded by the instruction compiler, and finally, the driving circuit drives the execution circuit to achieve various instruction operations.
