Abstract

RFID tag awareness information and sensor data continuously change, and are categorized with the position. They are able to similar data in the side, called massive data to change in time. If two data are managed together, a convergence process of object awareness along change of environment is possible. If RFID middleware and EPCIS repository realized the integrated system, it is usable with the functions of middleware and repository at the same time. The real-time awareness information retrieval is possible without process, getting information from another middleware. In this paper, it is able to continuously read information from RFID reader and sensor equipment and store to database in order to make general object awareness and an object retrieval dependent on an environmental information change possible by real time. ALE-compliant middleware and EPCIS repository proposing for standards at EPCglobal is designed and implemented to be able to deal with RFID and sensor data to bases on the collected data.

RFID 태그 인식 정보와 센서 데이터는 지속적으로 변화하고, 위치에 따라 구분되며, 시간에 따라 변화하는 대량의 정보라는 면에서 유사한 자료라고 할 수 있으며, 두 자료가 함께 관리된다면 환경 변화에 따른 객체 인식 등의 융합 처리가 가능하다. RFID 미들웨어와 EPCIS 저장소가 통합된 시스템을 구현한다면 미들웨어의 기능과 저장소의 기능을 동시에 사용할 수 있으며, 미들웨어로부터 정보를 받아 가공 처리할 필요 없이 실시간 인식 정보 검색이 가능해진다. 본 논문에서는 일반적인 객체 인식과 환경 정보 변화에 의존하는 객체 검색을 실시간으로 가능하게 하기 위해, 장치로부터 정보를 지속적으로 읽어 데이터베이스에 저장하고, 수집된 자료를 기반으로 EPCglobal에서 표준으로 제안하는 ALE 기반 미들웨어와 EPCIS 저장소를 RFID와 센서 데이터를 함께 처리할 수 있도록 설계하고 구현한다.
