Abstract

The embodiment of the invention relates to a ship cluster situation analysis method under a conflict meeting situation, and the method comprises the steps: dividing a sensing area of a target ship into a plurality of virtual dynamic grids based on different stages of a conflict meeting process; determining connectivity in each virtual dynamic grid, and selecting representative ships in the virtualdynamic grids to reflect traffic conditions in the dynamic virtual grids; describing the acting force of the representative ship on the target ship through the acting granularity in the plurality ofvirtual dynamic grids; and scoring by adopting a fuzzy logic rule in combination with the action granularity to obtain the acting force borne by the target ship. According to the method, a language variable form is adopted, and regularity approximate reasoning is carried out on environmental information of a target ship in actual navigation; by analyzing the action granularity of the representative ship on the target ship in the virtual dynamic grid area under the conflict meeting situation, accurate perception and cognition information can be provided for collision avoidance decision of the intelligent unmanned ship and selection of the next navigable area, and the navigation safety is improved.

Description

technical field [0001] The present disclosure relates to the technical field of ships, and in particular to a method for analyzing the situation of ship clusters in conflict encounter situations. Background technique [0002] Smart unmanned ship is a kind of unmanned ship with autonomous navigation, intelligent engine room, energy efficiency management, cargo transportation and intelligent integration platform. This technology integrates technologies such as ship, communication, automation, robot control, remote monitoring and networked system , can realize autonomous navigation, intelligent obstacle avoidance and other functions. Compared with manned ships, intelligent unmanned ships have the advantages of high safety factor, economical and environmental protection, green energy saving and so on. The path planning of intelligent unmanned ships is the core content of the autonomous navigation system of intelligent unmanned ships. [0003] The ship cluster situation refers ...
