Abstract

The invention provides an AIS-based ship navigation process meteorological sea condition data fusion processing system and method, and the method enables the meteorological sea condition on a ship route to be mastered at any time in a return visit process through the superposition of the meteorological sea condition data in the ship historical trajectory playback. And a reference basis is provided for ship course behavior analysis, ship distress reason analysis and the like under meteorological sea conditions. In ship route planning, meteorological sea condition forecast data of 72 hours before and meteorological sea condition forecast data of 14 days in the future are superposed, so that the meteorological sea condition possibly faced on the planned route in the future can be mastered at any time when the route is drawn, and further the influence possibly brought by extreme weather on navigation can be avoided in advance, thereby ensuring the navigation safety.

Description

technical field

[0001] The invention relates to the technical field of marine data, in particular to an AIS-based system and method for fusion processing of meteorological and sea state data during ship navigation. Background technique

[0002] The historical ship trajectory is a method to restore the navigation process of the ship, but the trajectory information only contains attributes such as speed, course, heading, draft, etc., and cannot restore the marine meteorological conditions during the navigation process. The marine meteorological conditions in the trajectory information also have a great impact on the safe route design of the ship's navigation. Therefore, it is necessary to restore the marine meteorological conditions in the process of restoring the ship's lasting voyage. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide an AIS-based method for fusion processing of meteorological and sea state data during ship navigation, so ...
