为在船舶交通服务模拟器中实现对港口监控的模拟,提高船舶交通服务操作员的培训效率,对真实的船舶交通服务中心进行仿真,采用计算船舶间最近会遇距离及最近会遇时间的方式建立数学模型,基于船舶自动识别系统(Automatic Identification System,AIS)数据源进行数据处理,运用VC++编程语言完成系统开发。港口监控中对辖区水域船舶的危险实现了实时预警。利用天津港真实AIS数据对系统功能进行测试,测试结果表明,该系统能够准确识别辖区水域船舶的会遇态势及遇险情况。
In order to simulate the port monitoring in the ship traffic service simulator, to improve the training efficiency of the ship traffic service operator, to simulate the real ship traffic service center and to adopt the method of calculating the recent encounter distance and the recent meeting time of the ship The mathematical model is established, the data is processed based on the Automatic Identification System (AIS) data source, and the system development is completed by VC ++ programming language. Real-time early warning of the danger of ships in the waters under their jurisdiction in port surveillance. The system uses the real AIS data of Tianjin Port to test the system functions. The test results show that the system can accurately identify the encounter situation and the distress situation of the ships in the area waters.
