摘要

도로 주행에서는 기하구조나, 일기, 야간 등 여러 가지 조건에 따라 교통사고가 빈번히 발생된다. 본 연구는 교통사고가 빈번히 발생되는 위험구간에 안전표시등을 설치하고, 이를 상시 모니터링하여 자동 제어할 수 있는 원격모니터링시스템을 개발하였다. 시스템은 윈도우 기반으로 무선통신과 연결하여 운용하고, 지역제어기와 도로교통 안전표시등을 원격 제어하여 실시간 중계되도록 GIS기법을 적용하여 개발함으로써 시스템 운용상태를 분석하였다. 현장에 설치된 안전표시등의 배터리와 솔라셀의 운용상태를 분석한 결과 평상시는 잘 운용되다가 겨울철에는 낮은 기온으로 10∼20%의 성능이 저하되는 것으로 나타나 발전용량을 늘리거나 전력소비를 줄여 운용해야 하는 것으로 분석되었다.While driving on the road, traffic accidents occur frequently affected by various conditions such as road geometry, weather and nighttime. This study installed safety indicators in the danger zones where frequent traffic accidents occur and developed a remote monitoring system enabling automatic control at all times. The system is connected to wireless communication based on window OS and relayed in real time by remote control of the local controller and road traffic safety indicator, and the operational status of the system was analyzed using GIS technique. According to the results of analysis of the operational status of battery and solar cell in safety indicator installed in the field, it was found to operate well during normal condition but the performance was reduced by 10~20% during winter time due to the low temperature. In order to solve this problem, it is necessary to expand power generation capacity or reduce power consumption.
