The invention discloses a ship collision early warning method and device based on Beidou positioning. The ship collision early warning method comprises the following steps: acquiring ship information according to a Beidou positioning system; acquiring system ship information according to a ship automatic identification system; comparing the system ship data with ship data to obtain ship information of other ships within a set range around the ship; according to the ship information and the ship information of other ships, determining the nearest meeting distance and the nearest meeting time between the ships; and carrying out collision early warning according to the nearest meeting distance and the nearest meeting time. According to the embodiment of the invention, Beidou satellite data positioning information is adopted, a ship course, a speed, orientation, basic data and other information are combined, track characteristics of commercial ships and fishing ships are analyzed through historical data, and a collision model is established in combination with historical collision events. The Beidou satellite positioning data is used to solve the problem of high sea positioning data, and the accuracy and effectiveness of analysis are enhanced.
本发明公开了一种基于北斗定位的船舶碰撞预警方法及装置,根据北斗定位系统获取船舶信息;根据船舶自动识别系统获取系统船舶信息;将所述系统船舶数据与船舶数据比较,获取船舶周边设定范围内的其它船舶的船舶信息;根据船舶信息与其它船舶的船舶信息,确定船舶间的最近会遇距离及最近会遇时间;根据所述最近会遇距离及最近会遇时间进行碰撞预警。本发明实施例采用北斗卫星数据定位的信息,结合船舶航向、速度、方位、基础数据等信息,通过历史数据分析商船及渔船的轨迹特征,结合历史碰撞事件,建立碰撞模型。使用北斗卫星定位数据解决了远海定位数据的问题,加强了分析的准确性和有效性。
