Abstract

The invention discloses a ship collision avoidance method and system and a storage medium, and the method comprises the following steps: obtaining first information of a current ship and a plurality of target ships, the first information comprising speed information, relative distance, position information and course information; analyzing the meeting state of the current ship according to the first information; drawing a ship collision risk graph according to the meeting state; and determining a plurality of safe navigational speeds and a plurality of safe navigational directions of the current ship according to the collision risk graph. According to the invention, the meeting state of the current ship is analyzed according to the obtained first information, the ship collision risk graphis drawn according to the meeting state, and then the plurality of safety navigational speeds and the plurality of safety navigational directions of the current ship are determined according to the collision risk graph, so that a ship driver can select navigational speeds and navigational directions of various collision avoidance operations at the same time, and the occurrence probability of shipcollision accidents is effectively reduced to a certain extent. The method can be widely applied to the technical field of ship navigation safety.

Description

technical field [0001] The invention relates to the technical field of ship navigation safety, in particular to a ship collision avoidance method, system and storage medium. Background technique [0002] Ship collision is the most common type of accident in waterway transportation, and an important reason for the accident is the lack of collision risk awareness of ship drivers. The research shows that the existing ship collision avoidance methods only provide one kind of collision avoidance decision, but the actual situation is changeable. When the current collision avoidance decision cannot be implemented, the existing ship collision avoidance method cannot provide the driver with other collision avoidance decisions in time, so that the ship driver cannot choose other collision avoidance decisions for collision avoidance operations, resulting in the inability to avoid accidents in time. Contents of the invention [0003] To solve one of the above technical problems, the ...
