Embodiment Construction

[0020] The present invention will be described in detail below in combination with specific embodiments.

[0021] The technical route of the present invention is as figure 1 shown, including the following steps:

[0022] 1) Literature analysis and survey research. The literature analysis is mainly to analyze and summarize the related researches on navigation safety and maneuvering control of ships in ice areas at home and abroad; investigate port and shipping companies, maritime authorities, the Environmental Forecast Center of the State Oceanic Administration and other units, and obtain sea ice age, ice type, Based on data such as ice class, ice volume, and physical parameters, and typical accident cases of ships sailing in ice areas, research and analysis of the main parameters affecting sea ice on ship navigation safety are conducted.

[0023] 2) Study the ship-ice interaction mechanism based on the theory of fracture mechanics. Using the theory of fracture mechanics, th...

Abstract

The invention discloses Bohai sea ice region ship track control based on artificial neural intelligence. The Bohai sea ice region ship track control comprises literature analysis and investigation andresearch. Researching a ship-ice interaction mechanism based on a fracture mechanics theory; simulating and calculating the navigation stress condition of the ship ice area by using a finite elementmethod; designing an artificial intelligence neural control method based on DSC and MLP; and verifying the effectiveness of the Bohai sea ice area ship track control method by using a Matlab simulation experiment. The method has the advantages that marine traffic accidents in ice areas of the Bohai sea area can be reduced, and ship navigation safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to ship track control in the Bohai Sea ice area based on artificial neural intelligence. Background technique [0002] Sea ice poses a great threat to ship navigation, and it is difficult for ships to maneuver, and it is easy to deviate from the planned route and cause accidents such as collision and grounding. In order to ensure the navigation safety of ships in the ice area of ​​the Bohai Sea, investigate and analyze the sea ice conditions in the Bohai Sea and the main parameters affecting the navigation safety of ships, and use the theory of fracture mechanics to study the "squeezing, bending, and ice breaking" of ships in the ice-breaking process of flat ice. "The three-stage action mechanism and model, using the finite element method to numerically simulate the ice-breaking process of the ship sailing in the ice area in a straight line and turning motion, and calculate and analyze t...
