Embodiment Construction

[0074] The present invention will be further described below in conjunction with the accompanying drawings.

[0075] The purpose of the present invention is achieved by the following steps:

[0076] 1. Acquisition of environmental information of the sea area where the unmanned boat sails and the navigation status of the unmanned boat

[0077] The environmental information factors that may affect the unmanned boat's navigation at sea are collected through weather forecasts, and the environmental information factors that have a greater impact on the unmanned boat's navigation are screened out according to the degree of influence of these environmental factors on the unmanned boat's navigation. Analyze these environmental factors that affect the navigation of unmanned boats, avoid dangerous environments and use favorable environmental factors as much as possible. The current position of the unmanned boat is positioned by the global positioning system, and the accurate sailing st...

Abstract

The invention relates to an unmanned ship route optimization method based on environment forecast information. According to the method, environment information factors possibly influencing marine navigation of an unmanned ship are collected through meteorological forecast, the current position of the unmanned ship is confirmed through a global positioning system, and an accurate unmanned ship navigation state is obtained; modeling is performed on the environment of a sea area by considering the influences of static barriers in an unmanned ship navigation area and the meteorological factor of ocean currents on the unmanned ship in combination with obtained environment data; and design is performed based on an unmanned ship route planning algorithm of a particle swarm optimization algorithm,an unmanned ship route designed through the planning algorithm avoids the static barriers as much as possible, and the ocean current area beneficial for unmanned ship navigation is utilized. Throughthe method, the unmanned ship can design the route according to the environment forecast information, the route can be timely adjusted at any time according to weather environment changes, the situation that a bad environment on the sea area threatens the safety of the unmanned ship is avoided, and the economy and safety of unmanned ship navigation are improved.

Description

technical field [0001] The invention relates to a route planning method for an unmanned boat, in particular to a route optimization method for an unmanned boat based on environmental forecast information. Background technique [0002] With the continuous increase of the number of unmanned boats and the rise of transportation costs, the economy and safety of unmanned boats have been paid more and more attention. Therefore, designing a safe and economical route for unmanned vehicles has become the main way to save energy, reduce emissions and reduce costs. For a long time in the past, due to the backwardness of technical conditions, people determined the route more based on the experience of navigators, and the effect was not satisfactory. In recent years, with the development of science and technology, people's prediction of the marine climate environment has become more and more accurate. Based on the environmental information, the route planning for the unmanned boat can b...
