动态船舶领域模型在AIS环境下的避碰决策研究的应用

Application of dynamic ship field model in collision avoidance decision in AIS environment

在现代海洋贸易中,各种大型的船舶需要航行在有限的航道上,随之而来的是海洋交通事故也变得更加频繁,这给船运行业带来了巨大的经济损失,为了有效降低事故的发生率,人们采用了各种先进的自动化系统,如AIS系统,结合智能避碰算法来模拟船舶的运行动态,通过提升船舶自身的航行预测能力,有效减少了事故的发生。本文首先建立了船舶的动态模型,通过AIS决策系统进行辅助定位,然后采用避碰算法,进一步降低了定位误差,在提高了船舶航行效率的基础上,改善了船舶的航行安全性能。最后通过仿真对船舶的综合避碰性能进行验证,并与拟合值进行了比对分析。

In modern maritime trade,a variety of large ships need to sail on a limited waterway,followed by a maritime traffic accident that has become more frequent,which has brought great economic losses to the shipping industry.The use of a variety of advanced automation systems,such as the AIS system,combined with intelligent collision avoidance algorithm to simulate the operation of the ship dynamic,by enhancing the ship's own navigation prediction ability,effectively reducing the occurrence of the accident.In this paper,the dynamic model of the ship is established,and the AIS decision system is used to assist the positioning.Then,the collision avoidance algorithm is used to further reduce the positioning error,and the navigation safety performance of the ship is improved on the basis of improving the navigation efficiency.At the end of the paper,the comprehensive collision avoidance performance of the ship is verified by simulation and compared with the fitting value.
