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 naviga-tion safety,an analytical expression method of the danger perimeter and the early warning perimeter are pro-posed,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 theo-retical reference for ship collision avoidance decision-making and ship intelligent navigation.
