Automatic navigation system based on marine weather forecast

Abstract

The invention provides an automatic navigation system based on marine weather forecast. The automatic navigation system comprises a weather warning avoidance module, the marine weather forecast of a weather bureau is synchronized, and a bad weather level annotation image of a main channel ship route is generated; according to the performance and structure of a ship and draft of the ship, bad weather level resistance of the ship is determined; and according to an estimated ship route and duration of voyage, whether the ship route needs avoidance is determined, if the avoidance is needed, a timeperiod that bad weather influences the ship route is determined, and according to voyage cost and supply condition, whether the ship route needs to be changed or speed increase or decrease is performed is determined, so that the time period that the bad weather influences the ship route is avoided. The automatic navigation system based on the marine weather forecast realizes the effect of automatically planning a navigation route, avoids navigational hazard caused by weather and automatically performs storm warning, facts that navigational status can be influenced and danger can happen are determined when weather such as storm comes and after GPS positioning is performed, the channel is changed, and the ship reaches a port nearby, waits and retrieves information of nearby ports.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an automatic navigation system based on marine weather forecast. Background technique [0002] Ship automation. In the 1970s, computers were widely used on board. From the establishment of a centralized control room in the engine room of the ship to the emergence of unattended engine rooms and the remote control and telemetry of the main engine from the bridge, the automation of ship engine rooms has become a trend. In 1970, Japan's "Starlight Maru" was completed, creating a new era of pilot-machine integration. It was called a "super-automated ship" at the time. Ship automation has roughly halved the ship's capacity, reducing operating costs. The new ships built in the past 10 years can basically be called automated ships, and some of the ships with a high degree of automation are called "high-tech ships". Ship automation has moved from engine room automation to pilot autom...

Problems solved by technology

[0005] However, in the process of automatic navigation, existing ships are affected by wind and sea currents, and the navigation direction is prone to deviation, resulting in long routes and wasting time and resources.
