Intelligent human body composition scale based on double-frequency bioelectrical impedance measurement and cloud computing

Abstract

The invention discloses an intelligent human body composition scale based on double-frequency bioelectrical impedance measurement and cloud computing. The intelligent human body composition scale comprises an electronic scale detection system (10), wherein the electronic scale detection system (10) comprises a main control panel (11), a double-frequency bioelectrical impedance detection unit (12) and an electrode slice (13); the electrode slice (13) is electrically connected with the double-frequency bioelectrical impedance detection unit (12); the double-frequency bioelectrical impedance detection unit (12) is electrically connected with the main control panel (11); an electronic scale data transmission module (20) is electrically connected with the main control panel (11); the double-frequency bioelectrical impedance detection unit (12) comprises two frequency generators which are separately connected with the electrode slice (13); one frequency generator generates 500 KHz high frequency, and the other frequency generator generates 50 KHz low frequency; through the time-division measurement of human body impedance under the conditions of 500 KHz high frequency and 50 KHz low frequency, the intracellular fluid characteristic and the extracellular fluid characteristic of a human body can be fully distinguished from each other, and the correlation between the measurement result of the intelligent human body composition scale and a professional direct testing result can be remarkably improved.

technical field [0001] The invention relates to a human body composition scale, in particular to an intelligent human body composition scale based on dual-frequency bioelectrical impedance measurement and cloud computing. Background technique [0002] Based on the early single-frequency bioelectrical impedance measurement method, a single frequency cannot distinguish the characteristics of human intracellular fluid and extracellular fluid in detail. Based on this measure, the correlation between the empirical formula derived from the regression analysis and the professional direct test results is not high enough.

Problems solved by technology

[0002] Based on the early single-frequency bioelectrical impedance measurement method, a single frequency cannot distinguish the characteristics of human intracellular fluid and extracellular fluid in detail

Based on this measure, the empirical formula derived from the regression analysis does not correlate well enough with professional direct test results

[0003] The existing technology is to perform simple basic calculations based on empirical formulas on the single-chip microcomputer of the scale body. Due to the limitation of the single-chip computing power, the algorithm needs to be greatly simplified and the accuracy is lost. At the same time, once the equipment leaves the factory, it cannot be modified and improved, and the biological resistance cannot be used. The latest research results of resistance and body composition analysis can only be based on outdated, old or even empirical formulas derived from sample data of different races, resulting in poor test precision and accuracy

[0004] The application of existing technologies to the Internet is limited to cloud storage, without utilizing the powerful computing capabilities of cloud servers
