Ship navigation route planning and positioning system

Abstract

A ship navigation route planning and positioning system disclosed by the present invention comprises a main control module, a route planning module and a ship positioning module, the main control module controls the operation of a ship overall system, the route planning module plans the ship navigation route, the ship positioning module positions the ship position in real time, and the ship positioning module is used for positioning the ship. The route planning module comprises a historical route unit, a route planning unit, an obstacle avoidance alternative unit, an environment superposition unit and a comparison selection unit, the route planning module divides necessary areas in the route, the route is planned and segmented according to the necessary areas, the long-distance route is divided into the short-distance route, and the route planning module is connected with the route planning module and sends position information when encountering danger. According to the method, the route is finely planned from a microscopic angle, so that the navigation of the route is more guaranteed, the route is planned in a segmented manner, and different routes can be planned for each segment, so that the routes of different segments are combined, and more choices are provided for navigation.

Description

technical field [0001] The invention relates to the technical field of ship navigation, in particular to a ship navigation route planning and positioning system. Background technique [0002] Ship routes The routes used by ships to navigate are divided into regular routes and irregular routes according to the mode of ship operation. Regular routes refer to the use of fixed ships, sailing according to fixed schedules and ports, and operating passenger and cargo transportation business at relatively fixed rates. Regular routes, also known as liner routes, mainly carry miscellaneous cargo, and irregular routes are routes selected temporarily according to the needs of freight. Ships, shipping schedules, and ports of call are not fixed, and they operate bulk and low-cost cargo transportation. Business-oriented routes; [0003] However, there are many deficiencies in the planning of the ship's route. When the course is long, the actual sailing situation cannot be carefully consid...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a navigation route planning and positioning system for a ship, which can effectively solve the problems in the planning of the ship route proposed in the above-mentioned background technology. When the course route is long, the actual navigation cannot be carefully considered. There are many deviations between the planned route and the actual driving, especially the problem of long-distance navigation
