The invention relates to the technical field of ship collision early warning, in particular to a ship collision early warning method based on a Beidou positioning system, and compared with the prior art, the ship collision early warning method obtains real-time position data of a ship by using a Beidou satellite system, and then calculates dynamic parameters of the ship. The collision risk model evaluates the collision risk among the distance, the relative speed and the relative course, provides early warning, provides decision-making manipulation measures, adjusts the course and the speed, provides early warning, provides decision-making support information, suggests the ship to take specific manipulation measures, adjusts the course and the speed, and minimizes the collision risk; according to the method, the problem of inaccuracy of a collision early warning system caused by influence of positioning data under the condition of severe weather or terrain shielding is effectively solved, and the problem that a model cannot adapt to various water area environments is effectively solved through collision risk assessment, so that the accuracy of collision early warning is improved, and the danger coefficient is reduced.

    本发明涉及舰船碰撞预警技术领域,尤其涉及一种基于北斗定位系统的舰船碰撞预警方法,与现有技术相比,本发明通过使用北斗卫星系统获取舰船的实时位置数据,随后计算舰船的动态参数,舰船的动态参数,碰撞风险模型评估距离、相对速度、相对航向之间的碰撞风险,提供预警的同时,提供决策的操纵措施,进行调整航向和速度,提供预警的同时,提供决策支持信息,建议舰船采取特定的操纵措施,进行调整航向和速度,最小化碰撞风险;有效解决了但天气恶劣或者地形遮挡的情况下,定位数据受到影响,导致碰撞预警系统的不准确性的问题,且通过碰撞风险评估进行评估有效解决了模型无法适应各种水域环境的问题,从而增加了碰撞预警的准确性,减少了危险系数。
