ELECTRONIC SCALE, MOBILE DEVICE AND BODY WEIGHT MEASUREMENT SYSTEM AND METHOD FOR WIRELESS TRANSMISSION

摘要

An electronic scale is provided. The electronic scale comprises a device body, a body weight measurement unit, a body weight data storage unit, a conversion unit and an audio transmission unit. The conversion unit encodes the weight data in the storage unit by using DTMF audio coding, converts the audio code to corresponding DTMF audio data and then outputs it. The audio transmission unit converts the DTMF audio data outputted by the conversion unit to an audio signal carrying DTMF audio information and then transmits it. A mobile device wirelessly communicated with the electronic scale, a body weight measurement system composed of the electronic scale and the mobile device, and a body weight data wireless transmission method are also provided. The electronic scale avoids the expensive wireless communication module, reduces cost, and ensures the reliability of data transmission.
