Problems solved by technology

The communication (data transmission) between the mobile intelligent terminal and the electronic scale is the core issue. Obviously, the wired communication is limited by the cable, and the practicability is not strong; the wireless communication does not have this concern, and with the With the increasing development of wireless transmission technology, there are many ways to transmit data wirelessly, the most commonly used are 2.4GHZ RF, Bluetooth, WIFI, and infrared. Among these wireless data transmission technologies, although infrared is cheap, it can only be transmitted in a straight line.
Bluetooth and WIFI can truly achieve wireless transmission, but the cost is high

Abstract

The invention discloses an electronic scale using voice frequency to transmit data. The electronic scale using the voice frequency to transmit the data comprises a scale body, an intelligent terminal and a voice frequency transmission/receiving system, wherein wireless data transmission is carried out between the scale body and the intelligent terminal, and the voice frequency transmission/receiving system is used for receiving audio signals generated by the scale body or the intelligent terminal, and transmitting the audio signals generated by the scale body or the intelligent terminal. According to the electronic scale using the voice frequency to transmit the data, due to the facts that the voice frequency transmission/receiving system is used for transmitting voice frequency carriers with frequencies larger than 20KHz to achieve wireless data transmission between the scale body of the electronic scale and the intelligent terminal of the electronic scale, and the frequencies which are larger than 20KHz cannot be recognized by human ears, the mode is low in cost, the cost is greatly reduced compared with the cost of the Bluetooth and the cost of the WIFI, and the problem that wireless transmission of the electronic scale is limited by the cost is solved.

Description

Technical field [0001] The invention relates to an electronic scale, in particular to an electronic scale that uses audio to transmit data. Background technique [0002] People's demand for electronic scales is no longer satisfied with checking the weight value at close range, but hopes that the specific weighing situation can be conveniently checked on mobile smart terminals (such as mobile phones) at medium and long distances. The communication (data transmission) between the mobile smart terminal and the electronic scale is the core issue. Obviously, wired communication is limited by cables and is not practical; wireless communication does not have this concern, and with With the increasing development of wireless transmission technology, there are now a variety of wireless data transmission methods, the most commonly used are 2.4GHZ RF, Bluetooth, WIFI, infrared. Among these wireless data transmission technologies, infrared is cheap, but it can only be used for linear transmi...
