건축자재 재사용을 위한 RFID 관리시스템

Abstract

Using the radio wave, RFID(: Radio Frequency IDentification) wirelessly transmits the unique information saved in a tag attached on the specific object. The study and experiment of the conventional construction management system based on RFID only focus on for managing the used amount and location of the construction materials in the construction stage, but they do not consider the status management system for the recycling materials in the construction stage or the building deactivation. Also, the management system with a function of identifying and managing the location information of the construction materials, employing RFID for reusing it, is not actively developed. In this thesis, we propose the effective RFID system for managing the status of the construction materials during the construction stage or the building deactivation. Employing RFID with the frequency of 900MHz, the proposed system consists of the reader unit, communication unit, and memory unit. In addition, we propose the system with a function of estimating and saving the location information of the specific construction materials, based on the estimated distances between the sub distance measurement unit and reader. The localization algorithm employed in this thesis is based on traditional TOA(: Time of Arrival) trilateration technique.
