Abstract

Modern society encounters various accidents due to industrialization and numbers of studies are going on to minimize damage from accidents. For prevention of accidents, it is necessary to design a system that helps making accurate judgment in emergency cases and is able to instantly manage each contingency. Various studies are currently going on contingency information system under ubiquitous environment. However, there have not been sufficient studies on the system that is able to monitor and process multiple contingencies and thus we still have difficulties in coping with multiple contingencies promptly. This study designs a RFID/USN middleware system for multiple contingencies control that receives data from various kinds of sensors and saves data after time marking thus is able to provide conjectured context when requested.

현대사회는 산업화로 인해 다양한 재해를 접하게 되고, 그 피해를 최소화하기 위해 많은 연구가 이루어지고 있다. 재난의 예방을 위해서는 위험 상황에 대한 정확한 판단과, 그 상황 발생에 즉각적인 대처가 가능한 시스템의 개발이 필요하다. 현재 유비쿼터스 환경하의 상황정보시스템에 대한 다양한 연구들이 진행되고 있다. 그러나 다중 상황에 대한 모니터링 및 처리가 가능한 시스템에 대한 연구가 미흡하며, 이로 인해 다중상황에 대한 신속한 대처가 이루어지지 않고 있다. 본 논문에서는 다중상황의 처리를 위해 각종 센서로부터 데이터를 취득하여 시간 마킹 처리 후 데이터베이스에 저장하고, 사용자의 요구에 따라 추상화된 Context를 사용자에게 제공할 수 있는 다중상황 처리를 위한 RFID/USN 미들웨어를 시스템을 설계한다.
