Intelligent water cup drinking water volume calculation method

Abstract

The application provides a kind of intelligent water cup drinking water quantity calculation method, make full use of the high-precision ranging capability of dTOF sensor under static, obtain accurate reference water level before and after drinking water, fundamentally ensure the accuracy of water quantity calculation. Again, through GSensor sensor, the dTOF sensing data is compensated for inclination, so that dTOF can also provide valuable reference information in dynamic scenarios, overcoming the fatal flaw that traditional dTOF solutions must be vertically stationary. Further, through GSensor sensor, the drinking action sequence is accurately identified, effectively filtering non-drinking water false triggers (such as moving the water cup). Moreover, this method can use frequent "static state" dTOF data to automatically calibrate the small drift in water level measurement caused by environmental factors such as water temperature and bubbles, achieving long-term stability.
