초록

무선 위치 추적 시스템은 모바일, 로봇 추적 시스템 및 인터넷 위치 기반 서비스(LBS) 애플리케이션과 같은 응용분야에서 사용할 수 있다. GPS 시스템은 가장 잘 알려진 위치 추적 시스템이지만 실내에서의 사용이 용이하지 않다. 실내 위치 추적 시스템에 대한 비용 효율적인 측면에서 무선 주파수 식별(RFID) 위치 추적 방법을 연구하였다. RFID 시스템 대부분은 소모성 배터리를 사용하는 능동형 RFID 태그를 사용지만, 본 논문에서는 패시브 RFID 태그를 사용하는 저렴한 실내 위치 추적 시스템을 개발하였다. 정밀한 추적 알고리즘을 사용하기 위하여 패턴인식에 의한 위치 추적 방법과 회귀곡선을 생성하여 위치를 추적하는 시스템을 연구하였다. 시스템은 잡음으로 인한 오류 수준을 검증하여 테스트하였다. 회귀식에 의해 생성된 3차원 곡선은 미분방정식에 의해서 확률적으로 설명력이 높은 좌표를 추정하였다. 이 제안된 시스템은 모바일 로봇 시스템, AGV 및 휴대전화 LBS에도 적용될 수 있다.

Location positioning systems are available in applications such as mobile, robotic tracking systems and Wireless location-based service (LBS) applications. The GPS system is the most well-known location tracking system, but it is not easy to use indoors. The method of radio frequency identification (RFID) location tracking was studied in terms of cost-effectiveness for indoor location tracking systems. Most RFID systems use active RFID tags using expendable batteries, but in this paper, an inexpensive indoor location tracking system using passive RFID tags has been developed. A pattern matching method and a system for tracing location by generating regression curves were studied to use precision tracking algorithms. The system was tested by verifying the level of error caused by noise. The three-dimensional curves are produced by the regression equation estimated the statistically meaningful coordinates by the differential equation. The proposed system could also be applied to mobile robot systems, AGVs and mobile phone LBSs.
