船舶编队过闸航行三维实时仿真

Real Time 3D Simulation of Lockage of Ship Formation

多船编队自动协同过闸是一种能深入挖掘船闸通航潜能、保障航行安全的航运新模式。为评估和验证船舶编队过闸航行控制效果,研发了一种船舶编队过闸航行三维实时仿真系统。首先,设计了船舶编队过闸航行三维仿真系统分布式架构,结合船闸水域卫星图并利用映射技术构建了船闸水域场景地形,制作了基于Unity的船闸水域三维仿真静态和动态场景。其次,采用动态和静态模型相结合方式构建了船闸运行系统,并根据船舶自身尺度和船闸宽度等条件实时计算船舶编队状态,实现了船舶纵向、横向编队全过程三维实时动态仿真。最后,以船舶自适应巡航编队航行和多船双向编队过闸航行为验证实例,对船舶编队过闸航行三维实时仿真系统分别进行了验证,结果表明本系统能实时动态模拟船舶编队过闸全过程,并准确计算船舶编队过闸航行状态,可为未来实现船闸水域船舶编队航行提供重要的基础平台支撑。

In order to evaluate and exam the effectiveness of the control of ship formation lockage,a 3D real time simulation system is developed.The system is designed as distributed architecture.The topographic map of the lock water area is generated based on the mapped satellite imagery of the area.The 3D simulation of static and dynamic scene is generated with Unity.The complete blockage system is modeled with the combination of static and dynamic models.The formation of ships depends on ship's dimensions and the width of the lock,so the simulation of the blockage process is carried out for column formation and side⁃by⁃side formation.The simulation system is verified through simulating the processes of adaptive cruise formation lockage and two⁃way multiple formation lockage.
