The invention discloses a detection and early warning method and system for a ship navigation tracking behavior, and relates to the technical field of ship navigation early warning, and the method comprises the steps: S1, obtaining the head direction, average navigational speed, course angle and latitude and longitude coordinate data of adjacent ships through an AIS system on a ship, judging the meeting situation of the ship through a preset judgment process, and carrying out the early warning of the ship navigation tracking behavior; early warning is given out in time according to the meeting situation; s2, monitoring an AIS signal of the ship, and carrying out early warning reminding on the ship when the AIS signal is missing or the frequency fluctuation is greater than a preset reference value; and S3, according to the average navigational speed of the ship, whether the average navigational speed of the ship is smaller than a threshold value within set time and does not leave the set area range or not is judged within the set area range, and if yes, drifting risk early warning is sent out. According to the method, the defects of an existing ship tracking behavior management method can be overcome, and the safety and efficiency of marine ship navigation are improved.
本发明公开了一种船舶航行追越行为的检测预警方法及系统,涉及船舶航行预警技术领域,包括S1:通过船舶上的AIS系统分别获取相邻船舶首向、平均航速、航向角以及经纬度坐标数据,通过预设判断流程判断船舶的会遇态势,并根据会遇态势及时发出预警;S2:监测船舶的AIS信号,对AIS信号缺失或频率波动大于预设参考值时的船舶进行预警提醒;S3:根据船舶的平均航速,判断在设定区域范围内,船舶的平均速度在设定时间内是否小于阈值且未离开设定区域范围时,若是,则发出淌航风险预警。本发明能够解决现有船舶追越行为管理方法存在的缺陷,提高海洋船舶航行的安全性和效率。
