Abstract

When the disaster like earthquake in urban area occur, due to the collapse accidents for subway, tunnel space with buildings or underground area, enormous property and human damage are happened. Specially, since it is difficult to identify survived status of humans within collapsed debris and accurately buried locations of the humans, inputs of considerable time and manpower for rescuing them are required. Besides, secondary damage can be occurred by additional collapses. The aim of this study is to propose a stochastic location positioning method that enables to provide aid information by determining locations of mobile devices for buried persons in 2-D plane using wireless communication technologies. This study selected a detection method for buried persons based on Wi-Fi signal, and identified characteristics of signal strengths by distance unit. Using these methods, a stochastic location detection model in 2-D plane was built. It is expected that this technology will be utilized as a core technology that can protects safety and human life of the public by providing data for rescuing quickly buried persons in cases of national disasters for future.

도심지에 지진과 같은 재난 발생시 건물이나 기타 지하부를 갖는 지하철, 터널 공간 등의 붕괴사고로 인해 수많은 인명 및 재산피해가 발생된다. 특히 붕괴 잔해에 매몰된 인명의 생존 상태를 파악하거나 매몰자의 매몰위치를 정확하게 파악하는 것이 곤란하여 구호에 상당한 시간과 인력이 투입되는 실정이며, 추가 붕괴에 따라 2차 피해가 발생될 수 있다. 본 연구에서는 이를 해결하기 위해 무선통신 기술을 활용하여 2차원 평면에서 매몰자의 휴대기기 위치를 측위하여 구호 정보를 제공할 수 있도록 하는 확률적 방법론을 제안하는 것이 목적이다. 즉, Wi-Fi 무선신호 기반의 매몰자 탐지 방식을 선정하여, 거리별 신호 강도 특성을 확인하였으며, 2차원 평면에서의 확률적 기반 위치 탐지 모델을 제안하였다. 이는 향후 국가 재난발생시 신속한 매몰자 구호를 위한 단서를 제공함으로써, 국민의 안전과 인명을 보호 할 수 있는 핵심기술로 활용될 수 있을 것으로 기대된다.
