Abstract

Fishing boats more than 5 tons is obliged to VHF DSC by Fishing Vessels Act and Vessel Safety Act. The owner of the fishing vessel is equipped to the automatic position reporting device in accordance with the Notice of the Minister of Land, Transport and Maritime Affairs to regulations, shall be ensure to navigations safety and in order to respond quickly in the event of maritime accidents on fishing vessels. East sea set up to start in 2012, which is now underway the annual install plain to the yellow sea and the south sea for VHF coast stations. It is web-based remote operation of DSC on the remote control and monitoring in Fishery Information Communication Station for the coastal VMS construction project. All fishing vessels is VHF DSC in conjunction with the GPS that location information transmitted to the coast station. automatically by the DSC call. This paper has been studied on the communications coverage set up and traffic operation for realization a roaming service by navigation route tracking and RSSI techniques in parallel algorithm refer to VHF DSC coast stations in east sea.

5톤 이상의 어선에는 VHF(Very High Frequency) 대역의 DSC(Digital Selective Calling)가 어선법과 선박안전법에 의무화되어 있다. 어선의 무선설비 관련 규정에는 안전운항을 확보하고 해양사고 발생시 신속하게 대응하기 위하여 선박의 소유자는 국토해양부장관의 고시에 따라 어선위치 자동발신 장치를 갖추도록 규정하고 있다. 따라서 어업정보통신국은 2012년 동해를 시작으로 남해와 서해에 연차적으로 VHF 해안국을 설치하고, 웹기반으로 리모트 콘트롤 및 모니터링에 의하여 DSC를 원격으로 운용하는 연안 VMS(Vessel Monitoring System) 구축사업이 추진중에 있다. 모든 어선의 VHF DSC는 GPS와 연동되며 DSC의 호출에 의하여 자동으로 위치정보를 중계소에 전송하게 된다. 본 논문에서는 동해권의 VHF DSC 해안국을 대상으로 통신해역 설정과 운용 그리고 등록선박의 항해에 따른 권역별 로밍서비스를 실현하는 항적추적과 RSSI (Received Signal Strength Indication) 기법을 병행하는 알고리즘을 연구하였다.
