Abstract

In this paper, we configure a Radio Frequency IDentification (RFID) gateway using an arduino and raspberry pi which are recent issues with a representative open source hardware. RFID technology is emerging as a key technology in a variety of environments as a technique to automatically identify objects using a radio frequency signal. In this paper, we propose a distributed RFID gateway for providing various communication methods and processing a large amount of RFID tag information efficiently, and to increase the scalability and middleware communication efficiency of the RFID reader. Existing RFID middleware systems have the problems that they should adhere the web service for interworking with a reader and the communication standard. Therefore, in this paper, we comprise our RFID gate to satisfy not only the serial communication configuration but also various digital signal processing standard so that it increases the communication efficiency of the middleware system.

본 논문에서는 최근 이슈가 되고 있는 대표적인 오픈소스 하드웨어인 아두이노와 라즈베리파이를 이용하여 RFID (Radio Frequency IDentification) 게이트웨이를 구성한다. RFID 기술은 라디오 주파수 신호를 이용하여 자동으로 사물을 식별하는 기술로써 다양한 환경에 핵심 기술로 부각되고 있다. 본 논문에서는 다양한 리더의 통신 방법과 대량으로 발생하는 RFID 태그 정보를 효율적으로 처리하기 위한 분산형 RFID 게이트웨이를 제안하고, RFID 리더의 확장성과 미들웨어 통신 효율성을 높이고자 한다. 기존 RFID 미들웨어는 리더와 연동을 위한 웹 서비스 또는 표준 통신 규격을 준수해야하는 문제점이 존재한다. 따라서, 본 논문에서는 RFID 리더 제작 시 시리얼 통신 이외에 다양한 방식의 디지털 신호처리 방식의 통신 규격을 만족하도록 구성하여 미들웨어의 통신효율을 증대시킨다.
