摘要
内河船舶碰撞事故导致重大生命及财产损失,已经引起人们的高度关注.提出一种内河船舶自动避碰路径优化的研究方法,建立了内河船舶操纵运动数学模型,将遗传算法运用到内河船舶避碰路径选优中,提出内河船舶避碰路径优化准则,并构建一种考虑内河航道中运动船舶及障碍物的适应度函数.优化结果表明了本方法的可行性.
The problem of ships collision accident in inland waterways has been increasingly concerned because it may cause great losses in human life and property and bring environmental pollution. An approach to solving this problem is proposed in this paper. As the basis of ship collision avoidance system, a mathematical model of ship maneuvering motion is first described. Then, optimization ap- proach based on genetic algorithm is applied to seek the ship trajectory considering different navigational constraint conditions of a ship in inland waterways. In this approach, a fitness function is used to model the constraints including target ship and obstacles. The optimal results show that the present method is efficient and can be further applied to the ship automatic collision avoidance system.
