Abstract

In this paper, we propose an indoor logistic tracking system that identifies the location and inventory of the logistics in the room based on fingerprints. Through this, we constructed the actual infrastructure of the logistics center and designed and implemented the logistics management system. The proposed system collects the signal strength through the location terminal and generates the signal map to locate the goods. The location terminal is composed of a UHF RFID reader and a wireless LAN card, reads the peripheral RFID signal and the signal of the wireless AP, and transmits it to the web server. The web server processes the signal received from the location terminal and stores it in the database, and the user uses the data to produce the signal map. The proposed system combines UHF RFID with existing fingerprinting method to improve performance in the environment of querying multiple objects.

본 논문에서는 핑거프린트를 기반으로 실내에 있는 물류의 위치와 재고를 파악하는 실내 물류 위치추적 시스템을 제안한다. 또한 이를 통해 실제 물류 센터 환경 인프라를 구축하고 물류 관리 시스템을 설계 및 구현하였다. 제안하는 시스템은 위치 단말기를 통해 신호 세기를 수집하고 신호지도를 제작하여 물품의 위치를 파악한다. 위치 단말기는 UHF RFID 리더기와 무선 랜카드로 이루어져 있으며 주변 RFID 신호와 무선 AP의 신호를 읽어 웹서버로 전송한다. 웹서버는 위치 단말기로부터 받아온 신호를 가공하여 데이터베이스에 저장하고 사용자는 해당 데이터를 이용하여 신호지도를 제작한다. 제안하는 시스템은 기존 핑거프린팅 방식에 UHF RFID 결합하여 다수의 객체를 조회하는 환경에서 성능을 개선하였다.
