Wind recognition system and method for wind recognition using microphone

Abstract

A wind recognition system includes a sampling unit to sample data inputted through a microphone, an amplitude analysis unit to analyze an amplitude pattern of the sampled data, and a wind recognition unit to recognize the inputted data as wind if the analyzed amplitude pattern corresponds to a wind pattern. The amplitude analysis unit obtains amplitude data from the sampled data, and determines that the analyzed amplitude pattern corresponds to the wind pattern if the amplitude data includes n amplitudes each having a predetermined size. Alternatively, the amplitude analysis unit determines that the analyzed amplitude pattern corresponds to the wind pattern if a standard deviation of amplitudes included in the amplitude data is less than a reference deviation. Also, the wind recognition unit may recognize the inputted data as wind if the analyzed frequency spectrum of amplitude data corresponds to a wind prototype.
