Electronic scale, mobile equipment, body weight measuring system and wireless transmission method

Abstract

The invention belongs to the technical field of measurement of human body weight, relating to an electronic scale. The electronic scale comprises a device main body, a body weight measuring unit, a body weight data memory unit, a conversion unit and an audio transmitting unit, wherein the conversion unit is used for carrying out DTMF (Dual-Tone Multi-Frequency) audio decoding on body weight data in the memory unit, converting the decoded body weight data into corresponding DTMF audio data and outputting the DTMF audio data; and the audio transmitting unit is used for converting the DTMF audio data output by the conversion unit into a sound signal carrying DTMF audio information and transmitting the sound signal. The invention simultaneously provides mobile equipment which can wirelessly communicate with the electronic scale; and by integrating hardware equipment, the invention also provides a body weight measuring system comprising the electronic scale and the mobile equipment as well as a body weight data wireless transmission method. According to the invention, an expensive wireless communication module is avoided, thus the cost is reduced; meanwhile, the reliability of data transmission is ensured and the convenience for users is realized.

Description

technical field [0001] The invention relates to an electronic scale, in particular to a method for transmitting and receiving measurement data of the electronic scale. Background technique [0002] The current electronic scales mostly use sensors and single-chip microcomputers to complete the measurement of human body weight, and display the measurement results through LCD displays, but it is impossible to record statistics and further analysis of personal weight measurement results. [0003] For this reason, CN201666812 discloses an electronic scale with a wireless interface that transmits data to a computer wirelessly, and uploads wireless body weight data to the computer and the Internet through a Bluetooth transceiver or a 2.4G wireless transceiver, so that personal health data can be stored permanently. save and analyze. [0004] Although the above technical solutions bring certain convenience to the measurer, there are still the following disadvantages in use: the co...

Problems solved by technology

[0004] Although the above technical solutions bring some convenience to the measurer, there are still the following deficiencies in use: need to increase the communication module, thereby increasing the cost of the product; The device needs to be paired and authenticated, which increases the difficulty of operation

[0005] In the conventional technology, DTMF is widely used in the telephone field, but the transmission and reception of DTMF signals are basically based on the telephone network as the medium, that is, telephone lines, antennas, and electromagnetic waves as the carrier , there is no application for short-distance data transmission using sound as the medium
