Research And Implementation Of Indoor Positioning Based On RFID

Indoor positioning technology the practicability and necessity become to be more significant, Radio frequency identification is a kind of wireless communication technology, it throughs the specific target radio signal recognition to read and write data.This paper will study the indoor positioning technology based on RFID. In order to meet the requirements of indoor positioning design the system. Positioning system will be composed of two functional modules:data acquisition, storage middleware module and PC positioning module. The middleware will read and write to the RFID initialization, and can each read electronic tag read-write data upload, and stored in the database. Positioning the PC module according to the user identification code that is material, using simple algorithm, positioning the region supplies.The basic framework of the positioning system bases on the design, implementation scheme design and positioning system. Implementation of the scheme includes:middleware and reader communication, middleware and reader communication, middleware and reader communication, computer data processing and human-computer interaction. The positioning algorithm is designed. The positioning algorithm is the acquisition of electronic tag time to sort, according to the ranking results corresponding to the read and write information to determine the antenna, RFID indoor location.In this paper, after the completion of locating scheme design, mainly is the selection of hardware RFID RF equipment, server, build a middleware platform. The performance analyses of RFID RF equipment, analysis results show that, select the RFID radio equipment to meet the requirements of the project.Research of software design, the positioning system including:reader data acquisition software design, collecting information storage software design, system design, software interface location area location algorithm of software design.In this paper, the simulation experiment is carried out on the system, the experimental results show that the positioning system, this project can realize indoor location on the electronic label, can be an indoor localization of material automation system, information collection does not need manual operation, automatic scanning material information, the liberation of productive forces, improve work efficiency, accurate area positioning.
