Abstract

The invention provides a positioning-based ship collision prediction method and device. The method comprises a monitoring step, an intersection calculation step, a crossing distance calculation step,a crossing distance and early warning distance calculation step, an intersection arrival time calculation step, an arrival time difference and predetermined time interval judging step, and a collisionprediction step. Only when the crossing distance of two ships is less than a preset early warning distance is collision prediction performance and only when the difference of intersection arrival time of two ships is within a predetermined time interval is a predication result of possible collision output, so that the operation quantity for collision prediction is greatly reduced and waste of operation resources is reduced. The prediction method has no direct relation with the relative distance of any two ships, so that error judgment caused by relative distance early warning can be prevented. For ships sailing on the water surface of a current area, if a ship may collide with another ship, early warning can be given to the ship in advance, so that ship collision accidents on water surfaces can be effectively prevented and reduced.

Description

technical field [0001] The invention relates to the technical field of ship safety monitoring, in particular to a positioning-based ship collision prediction method and device. Background technique [0002] Ship safety monitoring includes ship positioning, tracking of historical trajectories, ship status monitoring, ship anti-collision warning, etc. Among them, the ship anti-collision warning is mainly to monitor the surrounding environment of the ship and other large and small ships, and when the approaching distance reaches the set safe distance, an alarm is issued to avoid collisions. [0003] The ship anti-collision warning method in the prior art predicts the collision according to the relative distance between the two ships. This prediction method does not take into account the course of the ship, and it is easy to cause dangerous misjudgment. However, if the collision prediction between all ships in the current water area is targeted, the amount of calculation is too...
