Abstract

An embodiment of the present disclosure relates to a method for analyzing the situation of a ship cluster in a non-conflicting encounter situation, which includes: dividing the perception area of ​​a target ship into multiple virtual dynamic grids from outside to inside in a non-conflicting meeting situation; Select a representative ship in the virtual dynamic grid, and the representative ship is used to represent the macroscopic traffic conditions in the dynamic grid area; in the virtual dynamic grid, the force of the representative ship on the target ship is described through the granularity of action; the combination of fuzzy logic rules is adopted The action granularity is scored to obtain the action force of the target ship and the disturbed ship; according to the combination of action forces, the virtual dynamic grid is merged and reduced. The disclosed method uses the action granularity to describe the action force of the target ship in the virtual dynamic grid; analyzes the size of the action granularity of the representative ship on the target ship in the virtual dynamic grid area, merges and reduces it, and provides the avoidance of unmanned ships. Provide accurate perception information for collision decision-making and selection of the next navigable area, improving navigation safety.

Description

technical field [0001] The present disclosure relates to the technical field of ships, in particular to a method for analyzing the situation of ship clusters in a non-conflict encounter situation. 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...
