Abstract

The invention belongs to the technical field of marine navigation, and particularly relates to a marine meteorological early warning navigation system and method based on an electronic chart. The method comprises the following steps: acquiring electronic chart information; receiving meteorological information; superposing the electronic chart information and the meteorological information to obtain initial navigation environment information, and obtaining a first planned route according to the initial navigation environment information, preset target port position information and current shipstate parameters; receiving severe weather alarm information sent by a shore-based data center, and performing risk assessment on a first planned route currently executed by a ship; if the risk assessment result is a high risk level, obtaining a local avoidance scheme according to the severe weather alarm information and the current ship state parameters, and re-planning to obtain a second plannedroute in combination with the local avoidance scheme and the first planned route; otherwise, allowing the ship to sail according to the first planned route. According to the method, manual operationis reduced, the decision-making efficiency is improved, a safe navigation route is provided, and the safe navigation of the ship is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of marine navigation, and in particular relates to a marine meteorological warning navigation system and method based on electronic charts. Background technique [0002] At present, the shipping industry has occupied an extremely important position in the field of world transportation. In order to ensure the safety of ship navigation, improve the economic benefits of shipping, and make maritime transportation more rational, meteorological navigation came into being. [0003] In recent years, with the continuous increase in the number of maritime transport ships, a dense and complex traffic situation has formed. At the same time, with the development of the logistics supply chain, higher requirements have been put forward for the cost and efficiency of maritime transport. Meteorological conditions lead to conflicts in safety, efficiency and energy saving in marine transportation, resulting in continuous occu...
