In recent years, there have been frequent safety accidents of ships striking fairway buoy, which has aroused great concern. This paper firstly analyzes the causes of the collision of ships with navigation marks, and then proposes an intelligent anti-collision warning method of navigation marks based on passive underwater acoustic positioning. This paper has designed a kind of intelligent anti-collision navigation marks. The underwater acoustic transducer is installed under the navigation marks to complete the acquisition of distance information between the ship and the navigation marks. When the dangerous ship enters the dangerous water area set in this article, through the early warning matrix lights mounted on the navigation marks and the AIS information center, targeted warnings are given to dangerous areas where dangerous ships are located. The supply-energy analysis results show that this intelligent anti-collision warning navigation mark generates more electricity per day than its power consumption, and at the same time, the rich electricity can be filled with lithium iron phosphate batteries, which guarantees the daily work of this navigation marks and provides stable power support for all parts of the navigation mark. This intelligent anti-collision early warning method can give full warning to dangerous ships, avoid the collision of ships with navigation marks, and ensure the safety of navigation at sea.
