Abstract

The invention relates to a method for ship collision avoidance in open waters, and the method comprises the following steps of establishing a collision circle according to the speed and distance of two ships, wherein the collision circle refers to a set of all possible collision points of the two ships; extending the heading lines of the two ships, and taking the points where the two heading linesintersect the collision circle as the possible collision points; making a circle respectively by taking all the possible collision points as centers and setting the distance parameter as the radius to form a possible collision point distribution model of the circle; and making the heading line of one ship away from the possible collision point distribution model of another ship. The method provided by the invention is capable of avoiding 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 waters. Background technique [0002] Ship collision avoidance follows the four main steps of "lookout-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 waters, it is more likely to cause negligence due to the influence of the navigation environment and cause collision accidents. 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 risk of the ship and the possible avoidance measures, the ARPA of the SPERRY system first propo...
