Abstract

When unforeseen accidents occur in a ship, it is important to save passengers safely and remove them from the accident area quickly. To solve such a situation, site information of passengers on board always must be identified. This paper implemented a site monitoring of crews and passengers based on the BLE and PLM combination, to prepare for unexpected accidents of the ships. This system was composed of BLE tag for crews, passengers and each room, PLM networks, data server, and monitoring PC. In this system, site information derived from the tag attached to the bodies and cabins of crews and passengers are transmitted through a power line network, and monitored on the screen of a monitoring PC. The proposed system guides them into the only authorized area considering the ship security and passengers' safety, and even has a special alarm call to warn them after entering an unauthorized area. This system enables the BLE-embedded tag battery to use for a long time because the BLE consumes low electric power, and can gain an economic advantage.

선박에 예기치 못한 사고가 발생할 때에는 무엇보다 승객을 신속하고 안전하게 구출하는 것이 중요하다. 이를 위해서는 상시 승객의 위치정보가 파악이 되어 있어야 한다. 본 논문에서는 선박의 예기치 못한 사고에 대비하기 위하여 저 전력 블루투스(BLE, Bluetooth low energy)와 전력선 모뎀(PLM, Power line modem)을 기반으로 승선자의 위치정보를 모니터링하고자 한다. 이 시스템은 승객 및 선실용 BLE 태그, PLM 네트워크, 데이터 서버 및 모니터링 PC로 구성된다. 이 시스템은 승객 및 승조원의 몸과 선실에 부착된 태그(tag)로부터 받은 위치정보를 선내에 설치된 전력선 네트워크를 통하여 송신하여 모니터링 PC에 실시간 모니터링 된다. 제안한 방식은 선박과 승객의 안전을 고려하여 승선자의 권한과 직책에 맞는 구역에 출입이 가능하도록 유도하며, 출입이 제한되는 구역으로 이동시에는 알람을 발생시켜 제한을 유도한다. 또한, 전력소모가 적은 BLE를 사용함으로써 BLE가 장착된 태그 배터리의 장기간 사용을 가능하게 하고, 경제적 이익을 가져올 수 있다.
