Method and system for dynamic optimization of unmanned ship weather route

Abstract

The invention relates to a method and system for dynamic optimization of the meteorological route of an unmanned ship. The method comprises: performing grid processing on the navigation area of ​​the ship to obtain a plurality of grid points; Calculate the evaluation value of grid points; during the navigation process of the ship according to the initial route, the grid points of the current position of the ship are compared with the initial route in real time, and the real-time meteorological data is compared with the meteorological data of the corresponding grid points; in response to the route Deviation or change of weather data, according to the real-time weather data, update the evaluation value of the grid point between the column where the ship is traveling and the end point to obtain the updated grid value; determine the best value according to the updated grid value. route. The present invention establishes a dynamic optimization model of the meteorological route of the unmanned ship based on the dynamic programming recursive equation, the model grids the sea area for the vessel to navigate, updates the evaluation value according to the real-time marine meteorological data, and obtains the best route according to the route evaluation value.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method and system for dynamically optimizing weather routes of unmanned ships. Background technique [0002] Meteorological route design is an important research content to ensure the safe and efficient navigation of intelligent unmanned ships. The safety and economy of routes are also two indicators to measure the quality of ship routes. Energy consumption and voyage time are two important factors affecting the economy of routes. . [0003] Traditional route optimization methods mostly use static weather information as the basis for weather route design, which cannot reflect the impact of real-time weather on routes, and lack the simultaneous consideration of energy consumption and voyage time. Realizing the shortest voyage time or the lowest energy consumption of the route cannot meet the actual navigation needs of ships. [0004] It can be seen that the existing methods have...
