초록

선박을 통한 관광 수요가 증가함에 따라 선박 사고에 대비한 안전한 운항 및 대처가 필요하다. 해상에서는 외부구조 지원을 신속하게 받을 수 없으므로, 자체적으로 피해 최소화를 위한 초기 대응이 매우 중요하다. 따라서, 2차 피해 방지를 위해 신속하고 정확하게 선박 내 승객 위치 파악이 필요하다. 본 연구에서는 선박의 특성을 고려하여 저전력, 초소형 등의 장점을 가진 지그비(Zigbee) 무선측위기술(PDT, Position determination technology)을 향상시킨 e-Zigbee(enhanced-Zigbee) 무선 측위 기술을 적용하였고 사용자 니즈(needs)에 맞게 측위 정밀도를 고려한 저가형과 고정밀 승객 위치 태그(tag) 및 액세스포인트(AP, Access point)를 제공하였으며 특성조사를 통해 측위정밀도를 향상시킨 실선 테스트베드를 구축하였다.

As ship-based tourism increases, safe sailing and management are necessary to prevent maritime accidents. Because external rescue support cannot arrive rapidly in the case of ship-related accidents, the initial response is very important for damage minimization. Further, for secondary damage prevention, it is necessary to accurately determine passenger positions. In this paper, considering the characteristics of a ship, the enhanced-Zigbee(e-Zigbee) position determination technology (PDT) is applied, which improved upon the Zigbee PDT by having advantages such as low power consumption and smaller size. According to user needs, a low-cost and high-precision passenger positioning tag and access point(AP) is provided. A ship testbed that yields improved positioning accuracy based on a performance evaluation is constructed.
