    Abstract

    Aiming at the problem that salt mist seriously affects the reading performance of radio frequency identification (R FID) tags, the salt mist effects on the performance of RFID tags are researched through simulation and measurement. The reading range of RFID tags in the salt mist environment is reduced because the boundary conditions of the test chamber reduce the antenna efficiency and gain. As the concentration of the salt mist in the test chamber increases, the environmental conductivity in the test chamber increases, and the RFID reading distance of the tag decreases. In this paper, a theoretical formula is proposed for calculating RFID reading distance in salt mist environment. Besides, RFID dynamic identification based on the salt mist environment platform is designed. Corresponding functions are obtained by fitting the experimental data. This function establishes the relationship between salt mist concentration and the RFID reading distance. The experiment shows this theoretical formula is feasible, and the system has high practicability. At the same time, the system shows that the reading distance decreases as long as the concentration of the salt mist increases.
