Collision avoidance steering judgment method conforming to international maritime collision avoidance rules

Abstract

The invention belongs to the technical field of ship collision avoidance, and discloses a collision avoidance steering judgment method conforming to an international seaborne collision avoidance rule, which comprises the following steps of: acquiring information such as speed, course, position and the like of a ship and an encountering ship according to a ship sensing and navigation system, and calculating the minimum encountering time; judging whether a collision risk exists or not according to the calculated minimum meeting time; if the collision danger does not exist, the ship does not take collision avoidance measures and continues to sail along the original track; if the collision danger exists, a collision avoidance steering judgment model is built with the ship as the center, and the steering range meeting the international maritime collision avoidance rule requirement is determined. According to the ship collision avoidance steering judgment method conforming to the international maritime collision avoidance rule, the problem of how to quickly convert steering obligations conforming to the international maritime collision avoidance rule into digital collision avoidance steering when the ship encounters collision danger is solved, and the standard degree and safety of ship navigation are improved.

Description

technical field [0001] The invention belongs to the technical field of ship collision avoidance, and in particular relates to a collision avoidance steering judging method in compliance with international rules for avoiding collision at sea. Background technique [0002] A large number of accident cases show that the main cause of marine safety accidents is the collision between ships and obstacles. International Regulations for Preventing Collisions at Sea (COLREGS) is a marine traffic rule formulated by the International Maritime Organization to prevent and avoid collisions between ships at sea. It defines the obligation of each ship to avoid collision when there is a risk of collision between ships. Studies have shown that about 50% of marine accidents are caused by human error, and another 30% of accidents are discovered and prevented by humans. The reason is, firstly, there are cases where the ship does not detect sudden obstacles during navigation; secondly, even if ...

Problems solved by technology

The reason is, firstly, there are cases where the ship does not detect sudden obstacles during navigation; secondly, even if sudden obstacles are detected, the environment is uncertain due to its moving direction and speed are constantly changing This directly leads to the fact that people need to determine the collision avoidance environment in which the ship is located in complex constraint classifications before they can determine the collision avoidance steering that can be adopted at present, which consumes a lot of time and reduces the safety of the ship; Thirdly, the International Regulations for Avoiding Collisions at Sea only have a semantic description of the ship’s steering obligation during collision avoidance. In the actual process of ship avoidance, the usual practices of seafarers, the actual experience of the pilot, etc. will have a significant impact on the specific decision-making scheme and the ship’s collision avoidance effect.
