Multi-ship encounter collision prevention method for dynamic searching intelligent ship

The invention relates to a multi-ship encounter collision prevention method for a dynamic searching intelligent ship. The multi-ship encounter collision prevention method comprises the steps of: S1, acquiring current position information, revolution angular speeds, ship speeds, ship lengths and ship motion conflict radii of the present ship and a plurality of coming ships; S2 acquiring a positionset of the coming ships as well as navigational speed and revolution angular speed ranges of the present ship at a next moment; S3, acquiring a predicted navigational point set through combining the navigational speed and the revolution angular speeds; S4, acquiring a distance evaluation function value of a predicted navigational point and the coming ships; S5, determining whether a brake distanceof the present ship is less than the distance evaluation function value, if so, recording the predicted navigational point, otherwise, activating emergent brake of the present ship; S6, and calculating an overall evaluation f
