船舶交通服务模拟器中实时预警功能的实现

Realization of Real-Time and Early-Warning Function in Vessel Traffic Service Simulator

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 achieve the simulation of port monitor in vessel traffic service （VTS） simulator and improve the training efficiency of VTS operators, the simulation of the VTS center was developed by using the mathematical model to calculate the distance and time of the closest point of approach. Automatic identification system data and the VC ＋＋ programming technology were also used in the system development. The function of real-time early-warning for the ships in jurisdiction waters was realized. System test was carried out by using the real data of Tianjin Port, with satisfactory results. The system can accurately identify approaching vessels and dangerous conditions in the covered waters.
