The invention relates to a ship illegal anchoring early warning analysis method based on AIS (Automatic Identification System) data, which comprises the following steps of: drawing a non-staying sea area range by adopting a plotting tool through a GIS (Geographic Information System) platform, and naming a plotted sea area; data acquired by the shore-based AIS acquisition equipment and the satellite acquisition equipment are accessed to a system platform in real time for integration and integration; judging whether the AIS data is located in a plotted sea area or not according to a geographic space relation for the accessed AIS data, judging whether the ship speed is within an identifiable ship speed range or not for the data located in the plotted sea area, and if the ship speed is lower than a set ship speed, bringing the ship into a pre-warning ship list; and calculating subsequent AIS data of the ship, and if the moving distance of the ship within a certain time is lower than a set ship speed, giving out an early warning. The ship can be quickly and accurately positioned to the corresponding sea area, and whether the ship is illegally stopped or anchored or not is judged.
本发明涉及一种基于AIS数据的船舶非法抛锚预警分析方法,通过GIS平台,采用标绘工具绘制不可停留的海域范围,并对标绘海域命名;将岸基AIS采集设备、卫星采集设备采集的数据实时接入系统平台集成与整合;对接入的AIS数据,通过地理空间关系判断AIS数据是否位于标绘的海域,对位于标绘海域的数据,判断船速是否在一个可鉴别的船速范围内,如果低于设定船速,将船舶纳入预告警船舶列表;对此船的后续AIS数据进行计算,如果船舶一定时间内移动距离低于设定船速,是则发出预警。本发明可快速、准确地将船舶定位到相应的海域,并判断船舶是否非法停留或抛锚。
