Unmanned ship global meteorological route dynamic planning method and system

Abstract

Embodiments of the invention relate to an unmanned ship global meteorological route dynamic planning method and system. The method comprises the following steps of acquiring an initial route and discretizing the initial route to obtain a plurality of initial waypoints, wherein the multiple initial waypoints include a starting point, an ending point and a plurality of intermediate waypoints locatedbetween the starting point and the ending point; collecting real-time meteorological data in the ship driving process; for the current waypoint of ship driving, performing multilevel decision in combination with the real-time meteorological data of the multiple waypoints from the initial waypoint to the current waypoint by position decision of the initial waypoint to obtain multiple correspondingoptimal waypoints; and dynamically planning non-navigation routes after the current waypoint according to the multiple optimal waypoints and the ending point. According to the method, real-time dynamic adjustment and planning are carried out on the positions of the waypoints on the initial route in a segmented multilevel decision mode, and dynamic optimization of the routes in the ship driving isrealized.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method and system for dynamic planning of global weather routes of unmanned ships. Background technique [0002] In recent years, with the rapid development of the shipping industry, global meteorological route design has become an important research content to ensure safe and efficient navigation of intelligent unmanned ships. The safety and economy of routes are two important indicators to measure the quality of ship routes. [0003] Existing studies mostly use static meteorological information as the basis for meteorological route design, and lack of consideration for route decision-making under the condition of meteorological information changes. Due to changes in maritime meteorological information, it is difficult to ensure that the overall navigation process is always optimal for the route obtained after one-time planning. Therefore, the existing static design method of m...
