摘　　要：为实现船舶智能航行,建立基于船舶航行状态的多元避碰周界.通过识别船舶航行风险,分析避碰双方的主尺度、航速、航向等多元因素对航行安全的影响机制,提出危险周界和预警周界的解析表达方法,构建面向海上安全航行的多元避碰周界.通过实例分别模拟了多航行状态的船舶和复杂海上障碍物的数字化安全界限,初步验证了多元避碰周界的可行性,可作为船舶避碰决策、船舶智能航行的理论参考.In order to realize intelligent navigation of ships,multiple collision avoidance boundaries based on ship navigation status are established.By identifying the risk of ship navigation and analyzing the impact mechanism of the main dimensions,speed,course and other multiple factors of both sides of collision avoidance on navigation safety,an analytical expression method of the danger perimeter and the early warning perimeter are proposed,and the multiple collision avoidance perimeter for safe navigation at sea is constructed.The feasibility of the multiple collision avoidance boundaries is preliminarily verified by simulating the digital safety boundaries of ships in multiple navigation states and complex obstacles on the sea through examples.It can be used as a theoretical reference for ship collision avoidance decision-making and ship intelligent navigation.
