Sound-controlled gas control system, method and device

Abstract

The present invention discloses a sound-controlled gas control system, used to adjust the height change of the generated flame. The system includes an audio module, a transformation analysis module, a driving module and at least one proportional valve. The audio module is suitable for preprocessing discrete audio data and generating complex-number data according to the result of the preprocessing. The transformation analysis module is suitable for performing a Fourier transformation according to the complex-number data to generate a plurality of frequency domain data and performing spectrum analysis on the frequency domain data to generate pulse width modulation data. The driving module is suitable for receiving the pulse width modulation data and converting to an opening control signal according to the pulse width modulation data. The proportional valve has a gas valve and is suitable for adjusting an opening and closing state of the gas valve according to the opening control signal.
