Abstract

The invention relates to a collision avoidance method for ships in open water, comprising the following steps: establishing a collision circle according to the speed and distance of two ships, wherein the collision circle refers to the set of all possible collision points of the two ships; extending the course lines of the two ships , the point where the two course lines and the collision circle intersect as the possible collision point; take all possible collision points as the center of the circle, set the distance parameter as the radius to make a circle, and form a circular distribution model of possible collision points; make a ship's possible collision point distribution model; A model of the distribution of possible collision points where the course line is far away from another ship. The present invention can avoid complex function calculations.

Description

technical field [0001] The invention relates to the technical field of ship collision avoidance, in particular to a method for ship collision avoidance in open water. Background technique [0002] Ship collision avoidance follows the four main steps of "look-out-judgment-action-verification". Through the research and analysis of many ship collision accidents, it is found that more than 80% of the collision accidents are caused by human negligence, and human negligence often Appearing in the two steps of "lookout" and "judgment", especially in open water, it is more likely to cause a collision due to negligence caused by the influence of the navigation environment. It can be seen that reducing human negligence through modern equipment and technical means is an effective measure to reduce collision accidents. [0003] In order to more intuitively show the current collision danger of the ship and the possible avoidance measures, ARPA of the SPERRY system first proposed the con...
