The invention discloses an AIS track data processing method for real-time monitoring of a ship situation. The method comprises the following steps: step 1, receiving and analyzing AIS data; step 2, AIS abnormal data cleaning; step 3, AIS track area attribute determination; 4, judging a maneuvering mode; step 5, carrying out self-adaptive statistics on the life cycle; step 6, pre-pushing; step 7, carrying out self-adaptive statistics on a pre-pushing period; step 8, ending pre-pushing; and step 9, updating and storing AIS static information. According to the method, data management of AIS tracks in a ship traffic management system is realized, abnormal data such as AIS jumping and fallback are eliminated, information such as historical updating time intervals and navigational speed changes of the AIS is comprehensively considered, the pre-pushing cycle and the life cycle of the AIS are subjected to self-adaptive statistics, and meanwhile, the pre-pushing cycle and the life cycle of the AIS are calculated in combination with geographic element information of a sea graph layer. AIS track data processing is carried out according to regions, and the effects of AIS track smoothness and high prediction precision are well achieved.
本发明公开了一种用于船舶态势实时监测的AIS航迹数据处理方法,包括步骤1、接收并解析AIS数据;步骤2、AIS异常数据清理;步骤3、AIS航迹区域属性判定;步骤4、判断机动模式;步骤5、自适应统计生命周期;步骤6、预推;步骤7、自适应统计预推周期;步骤8、结束预推;步骤9、AIS静态信息更新与存储。本发明实现了船舶交通管理系统中AIS航迹的数据管理,针对AIS跳跃、回退等异常数据进行剔除处理,并综合考虑AIS的历史更新时间间隔及航速变化等信息,自适应统计出AIS的预推周期及生命周期,同时结合海图图层的地理要素信息,分区域进行AIS航迹数据的处理,较好的实现了AIS轨迹顺滑且预测精度高的效果。
