Abstract

Real time location system was development for safety management at road and bridge maintenance field. The system can check the real-time location detection, movement history, behavior of a number of laborers. The system consisted of a Bluetooth and ZigBee that uses low-power. It had a very large error that the previous method for the position recognition by triangulation using the RSSI. Because This study proposed a new distance measurement and correction scheme using RSSI and accelerometer. It was evaluated in the maintenance field. A development system were evaluated in the field, the results are shown an error between 0.2 m and 0.4 m. And through the acceleration of history it was confirmed by determining possible to determine the safety situation of the laborers.

도로포장 및 교량 유지보수 현장에서 노무자의 안전을 관리할 수 있도록 실시간 위치정보 시스템을 개발하였다. 이 시스템은 다중의 노무자들의 실시간 위치 탐색, 이동 이력, 행동 특성을 확인할 수 있다. 이 시스템은 저전력 블루투스 및 지그비 통신시스템으로 구성되었다. RSSI를 이용한 삼각측량으로 위치 인식을 하는 과거의 방법은 매우 큰 오차를 가진다. 때문에 본 연구는 가속도계와 RSSI를 이용한 새로운 거리측정 방법 및 보정 방안을 제시하였다. 도로포장 및 교량 유지보수 현장에서 개발한 시스템의 오차를 평가한 결과 0.2 m~0.4 m의 오차를 나타내었다. 그리고 가속도 이력을 판별하여 통해 노무자의 안전 상황에 대한 판별이 가능함을 확인하였다.
