为了提高舰船航行的安全和效率，达到最佳操船效果，需要建立舰船自动智能避碰数字模型。当前模型在分析舰船避碰风险度的基础上，通过人工智能、进化计算和软计算等方法实现舰船自动智能避碰，存在避碰识别准确率较低的问题。本文提出一种新的舰船自动智能避碰数学模型，首先对舰船会遇态势进行判断；然后建立预测舰船碰撞风险判断模型，预测本舰船实施自动智能避碰方案后的复航时机是否已到，以及本舰船立即复航是否能够让清目标舰船或其他所有目标舰船；最后依据舰船碰撞风险判断结果，以当前舰船潜在碰撞风险为例，建立舰船自动智能避碰数学模型。仿真结果证明，所提模型能够实现舰船自动智能避碰。
In order to improve the safety and efficiency of ship navigation, to achieve the best boat effect, the need for ship automatic intelligent collision avoidance digital model to study. Based on the analysis of the risk of collision avoidance, the current model can realize the automatic collision avoidance of ships by means of artificial intelligence, evolutionary computation and soft computing. There is a problem that the accuracy of collision avoidance is low. In this paper, a new mathematical model of automatic collision avoidance of ships is proposed. First, the situation of ship encounters is judged. Then, the ship collision risk judgment model is established to predict the recovery of the ship after the automatic intelligent collision avoidance whether the ship has arrived, and whether the ship can be re-deployed immediately to clear the target ship or all other target ships. Finally, according to the ship collision risk judgment results, the current ship potential collision risk, for example, the establishment of ship automatic intelligence collision mathematical model. Computer simulation experiments show that the proposed model can achieve the ship automatic intelligent collision avoidance.
