Abstract

The problem of elderly people with weak physical health has become a very important issue in the aging society. Elderly people with very low judgment and decision-making skills often falls because of the degradation of the strength and balance. Due to the fall triggered off fractures, parenchyma damage, and casualties, generally fast emergency treatment is needed. In this paper, an automatic fall detection system consisting of a triaxial accelerometer and tilt sensor. Using the fall system, the performance of the system was analyzed in many situations. The experimental results showed more than 92% analytical skills.

고령화 사회에서는 노인의 신체적 취약성으로 인한 안전문제가 사회문제로 대두되고 있다. 판단, 상황대처 능력이 떨어진 노인은 체력과 균형감각 저하로 인하여 잦은 낙상을 경험한다. 낙상은 자칫 인명피해 및 골절, 유조직 손상 등을 유발 할 수 있으므로 빠른 응급대처가 필요하다. 따라서 본 논문에서는 사용자의 허리에 부착하여 일상적인 움직임에 대한 가속도의 변화 및 낙상이 발생하였을 때의 가속도의 변화를 측정하였다. 측정한 값을 이용하여 낙상 감지 시스템을 구현하였으며, 여러 가지 낙상 상황을 가정하여 낙상 검출 여부를 판별 하였다.
