Abstract

This study suggests a novel way of safety cognition with single sensor. It is beneficial to make the most of the 3-axis acceleration sensor for context inference. It has remarkable advantages that size is too small and less malfunction or error. This study shows the calculation of the common life safety through the events data from the 3-axis acceleration sensor only. That includes the analyzation of the volume of energy and converting quantitative numerical value.

단일 센서만을 운용하여 옥외활동 중에 있는 사용자의 안전도를 측정하고 판단할 수 있는 방안을 제안한다. 3축 가속도 센서는 다른 센서와 비교하여 가격대비 인지 성능이 우수한 면이 있다. 크기가 작고, 측정하는 값이 상대적으로 에러와 장애로부터 독립적인 측면이 있다. 3축 가속도 센서를 부착한 개인이 옥외에서 비정상적인 상태로 돌입하는 것을 감지할 수 있도록 하기 위하여 3축 가속도가 감지하여 보고하는 에너지 값을 분석하고 이를 계산하여 실시간 안전도를 정량적으로 표기할 수 있도록 하였다.
