Liquid attributes classifier using soundwaves based on machine learning and mobile phone

摘要

The present invention relates to a liquid property determination apparatus, and more particularly, to a liquid property determination apparatus based on machine learning and a mobile phone using the same. To this end, the sound wave output unit 120 for transmitting a sound wave 30 of a predetermined form; a sound wave receiving unit 140 for receiving the sound wave 40 reflected by the sound wave 30 reflected from the surface 20 of the liquid 15; a signal processing unit 150 for converting the reflected sound wave 40 received by the sound wave receiving unit 140 into a signal in the frequency domain; a machine learning unit 200 for machine learning based on a plurality of liquid attribute data 210; Provided is a liquid property determination device based on machine learning comprising a; a control unit 100 for inputting a frequency domain signal to the machine learning unit 200 to determine the property of the liquid 15 do.
