Online Measurement of Alcohol Concentration Based on Radio-Frequency Identification

CODEN: JTEVAB

Abstract

This paper presents a method for online measuring signal backscattering and reading distance from radio frequency identification (RFID) tags attached to the surface of the liquid, and for calculating the corresponding alcohol concentration. We derive a theoretical formula on the reading distance and received power. Subsequently, the former measurement values are converted to the corresponding alcohol concentration. Experiments are performed using an ISO/IEC 18046-based measurement system in the ultra high frequency (UHF) RFID band [ISO/IEC 18046, “Information Technology—Radio Frequency Identification Device Performance Test Methods,” International Organization for Standardization, London, 2007]. A fitted model of the relationship of alcohol concentration, reading distances, and received power is established. Based on the proposed fitted model, the processor can calculate alcohol concentration in aqueous solutions. The experimental data are compliant to the theoretical counterparts. This online method could be applied to dynamic measurement in automatic assembly line and has the advantages of excellent versatility, high measuring accuracy, stable performance, and quick response speed.
