摘要
文中提出基于电子围栏与北斗定位算法的船舶偏航预警技术研究.有效融合电子围栏与北斗定位算法获取船舶轨迹数据,基于MapReduce制定与预处理船舶轨迹数据,通过长短期记忆网络预判船舶到达的下一个路段,计算船舶下一航迹点位置与海上风场区域边界的距离,判定船舶是否误入海上风场,若船舶误入风场,及时预警.结果表明:提出技术应用后获得的船舶通航路线预判结果与实际船舶通航路线保持一致,船舶偏航预警精度最大值为98%,充分证实了提出技术应用性能较佳.
An early warning method of ship yaw based on electronic fence and Beidou positioning algorithm was proposed to effectively integrate electronic fence and Beidou positioning algorithm to obtain ship trajectory data.Based on MapReduce,the ship trajectory data was formulated and preprocessed,and the next section of the ship was predicted through long-term and short-term memory networks.By calculating the distance between the position of the ship’s next track point and the boundary of the offshore wind field,it is judged whether the ship has strayed into the offshore wind field by mistake.If the ship strays into the wind field,give an early warning in time.The results show that the pre-judgment result of ship navigation route obtained after the application of the proposed technology is consistent with the actual ship navigation route,and the maximum accuracy of ship yaw early warning is 98%,which fully proves that the proposed technology has good application performance.
