Abstract

This paper suggests the system that allows nearby firefighters to read about the transmission direction of a distress signal and track the location by RSSI of received distress signal which is transmitted wirelessly after sensing the distress signal of a firefighter using the Wireless Sensor Network(WSN) based on IEEE 802.15.4 and Received Signal Strength Indicator(RSSI) in the building. Also, It was confirmed that the location tracking using RSSI is possible because the difference between theoretical value and experimental value is little when experiment using the proposed system.

본 논문에서는 IEEE 802.15.4 기반 무선센서네트워크(WSN) 및 수신신호세기(RSSI)를 이용하여 건물 내에서의 소방대원의 조난을 감지하고 무선으로 조난신호를 보냄으로써 근처 동료 소방대원이 수신신호세기(RSSI)를 통해 조난신호의 송신방향을 읽고 위치를 추적하는 시스템을 제안하였다. 또한, 제안된 시스템을 이용한 실험에서 이론값과 실험값의 오차가 작기 때문에 RSSI를 통한 위치추적이 가능하다는 것을 확인하였다.
