Abstract

The AIS(Automatic Identification System) has been widely used for ship safety at sea over the last 10 years. The AIS traffic load at VDL(VHF Data Link) has been continuously increased. As the traffic load at VDL increases, the quality of AIS service may be deteriorated. In the previous research, the AIS traffic has been analyzed in the major ports of Korea, and its problem due to traffic overload has been suggested. However, no solutions has been given so far. In this paper, the method of autimatically controlling the VDL traffic at AIS base station is represented.

AIS(Automatic Identification System)는 지난 10년간 해상에서 선박의 안전운항을 위해 광범위하게 사용되어 왔다. 이에 따라 AIS에서 사용하는 VHF 대역의 데이터 링크에서 통신량도 꾸준하게 증가하고 있다. AIS 디이터 트래픽의 증가는 AIS 서비스 통신품질의 저하를 야기할 수 있다. 국내 주요항만에서 AIS 통신량의 현황분석을 통하여 통신증가의 문제점을 지적한 바는 있지만 이에 대한 대책을 제시한 연구결과는 없다. 본 연구에서는 해상에서 AIS 기지국 장치에서 제공하는 메시지를 이용하여 AIS 기지국의 통신슬롯의 점유율을 분석하는 분석방법과 그 분석정보를 이용한 AIS 기지국의 자동 제어방안을 제시하고자 한다.
