Abstract
최근 전세계적으로 지진, 홍수, 화재 등 재난재해로 인한 인명피해가 늘어나면서 골든타임을 확보하기 위한 기술연구가 활발히 이루어지고 있다. 본 논문에서는 골든타임 확보를 위해 IoT 기술들을 사용해 재난 재해 발생 시 실제 발생원의 사용자를 최우선으로 찾아 전파하며, 주변지역 사용자로 차츰 범위를 확산시켜 전파하는 모델을 연구하였다. 국가 재난 재해 정보는 기상청 OPEN API를 사용하였으며, 해당지역의 세밀한 정보획득을 실시간 수집하기 위해 Crowd Sensing 기술과 BLE (Bluetooth Low Energy) Beacon 기술을 통합 연계한 시스템을 구축하였다. 특히 기존까지 기지국 기반 CBS를 사용하였다면 본 논문에서는 Beacon을 이용한 사용자 위치와 국가행정주소체계 네가지를 통합한 DB를 설계하여 맵핑함으로써 지역 사용자를 추정할 수 있게 되었다. 실험은 사용자의 수를 1천명씩 증가하는 방식을 통해 정보 확산 알고리즘의 정확도와 속도를 측정하였으며, 최종 2만명의 인원까지 1초 이내 연산하여 위험 전파 알림이 가능함을 확인하였다. Worldwide casualties caused by earthquakes, floods, fire or other disaster has been increasing. So many researchers are being actively done technical studies to ensure golden-time. In this paper if a disaster occurs, use the IoT technologies in order to secure golden-time and transmits the message after to find the user of the accident area first. When the previous job is finished, gradually finds a user of the surrounding area and transmits the message. For national emergency information, OPEN API of Korea Meteorological Administration was used. To collect detailed information on a relevant area in real time, this study established the system that connects and integrates Crowd Sensing technology with BLE (Bluetooth Low Energy) Beacon technology. Up to now, the CBS based on base station has been applied. However, this study designed and mapped DB in the integration of Beacon based user positioning and national administrative address system in order to estimate local users. In this experiment, the accuracy and speed of information dif6fusion algorithm were measured with a rise in the number of users. The experiments were conducted in a manner that increases the number of users by one thousand and was measured the accuracy and speed of the message spread transfer algorithm. Finally, became operational in less than one second in 20,000 users, it was confirmed that the notification message is sent.
