초록
화재 발생 시, 응급구조요원의 사망 사고가 빈번히 발생하고 있다. 이러한 사고 예방을 위해 구조요원의 정확한 위치추적이 필요하다. 구조요원의 위험성이 큰 대형건물들은 일반적으로 긴 일직선 복도의 한쪽 또는 양쪽에 방들이 배치된 구조를 가지고 있다. 그렇기 때문에 구조요원은 대부분 좁은 복도를 통해 이동하게 될 것이다. 이러한 좁은 복도는 UWB 신호를 수신하는데 있어서 공간적 제약이 매우 크다. UWB 송수신기는 이러한 공간적 제약을 고려하여 설치되어야 한다. 본 논문에서는 UWB 송수신기를 이용한 응급구조요원 추적 기법을 제안하였다. 제안된 방법은 2개의 시나리오에 대한 실험을 통해 검증하였다. 첫째는 넓은 공간에서 설치된 모든 UWB 신호를 수신할 수 있는 경우를 실험하였다. 둘째는 90도로 꺾이는 좁은 복도에서 LOS(Line of Sight) 신호만을 수신할 수 있는 경우를 실험하였다. 본 논문에서는 구조요원의 위치추정을 위해 EKF(Extended Kalman Filter) 기반 SLAM(Simultaneous Localization and Mapping) 기법을 이용하였다. 실험 결과, 본 논문에서 제안한 기법을 이용해 응급구조요원의 실내위치 추적이 가능함을 확인하였다.
Abstract
In the event of a fire, the deaths of emergency responder are frequent. Accurate positioning of the emergency responder is necessary to prevent such accidents. Large buildings with a high risk of the emergency responder generally have a structure in which rooms are placed on one or both sides of a long straight corridor. Therefore, most emergency responder will travel through narrow corridors. These narrow corridors have large spatial constraints in receiving UWB signals. The UWB transceiver should be installed in consideration of these spatial constraints. In this paper, we propose an emergency responder tracking method using UWB transceiver. The proposed method was verified by experimenting with two scenarios. The first scenario is when all the UWB signals installed in a large space can be received. The second scenario is where only a line of sight (LOS) signal can be received in a narrow corridor turning 90 degrees. In this paper, the Extended Kalman Filter (EKF)-based Simultaneous Localization and Mapping (SLAM) technique was used for the emergency responder tracking. As a result of the experiment, we confirmed that the location of the emergency responder can be tracked using the proposed method.
