The invention discloses a ship early warning method based on a bulking ellipse and bulking circle model, and relates to the technical field of early warning and monitoring. The early warning method comprises the following steps: establishing puffing elliptical models of two ships; calculating parameters such as a domain distance between the two ships, a safety distance, a linear distance, an included angle between a tangent line of a circle taking the safety distance as a radius and a relative position connecting line, and an included angle between a relative velocity vector and the relative position connecting line; each parameter is compared with the collision detection distance, the TCPA and the DCPA to realize blue early warning, orange early warning and red early warning. According to the method, the bulking ellipse model is constructed for the two ships, the relative position and the dynamic relation between the two ships can be predicted more comprehensively by calculating various parameters between the two bulking ellipses, and the method is used for carrying out early warning of different levels on collision risks of different degrees, so that the sailing safety is improved.

    本发明公开了一种基于膨化椭圆与膨化圆模型的船舶预警方法,涉及预警监测技术领域。所述预警方法包括以下步骤:建立两船的膨化椭圆模型;计算两船之间的领域距离、安全距离、直线距离、以安全距离为半径的圆的切线到相对位置连线之间的夹角以及相对速度向量与相对位置连线之间的夹角等参数;各参数与碰撞检测距离、TCPA以及DCPA进行对比,实现蓝色预警、橙色预警以及红色预警。本发明将两艘船构建膨化椭圆模型,通过计算两膨化椭圆之间的多种参数,能够更加全面的预测两艘船之间的相对位置和动态关系,用于对不同程度的碰撞风险进行不同等级的预警,提高航行的安全性。
