Location-based Safety Risk Information Exchange Method for Intelligent Ships

Navigation environment and traffic flow information are important decision-making information for safe navigation of ships and play an increasingly important role in the evolution of autonomous ships. To improve the technical level and ability of perception, cognition and decision-making of ship intelligent navigation system, a concomitant location-based information exchange method of navigation safety risk is proposed, an application layer message coding format suitable for low broadband and multi-link is designed, and an active information exchange mode based on ship route planning is established.
