The invention discloses a historical data-based method for judging whether a ship enters and leaves a river at a controlled reach, and belongs to the field of intelligent shipping and ship navigation application. The method comprises the following steps: on the basis of AIS historical data of a ship in a control river reach, reading coordinate data and course data in the data, carrying out statistical analysis on the course data by taking a channel mileage line of an electronic channel chart of the Yangtze River as a boundary, and generating channel mileage to judge the course. Through the method, the ship heading can be quickly judged to be water feeding or water discharging only by inputting the analyzed ship position data and the ground heading data, the ship heading water feeding and water discharging judgment process is effectively simplified, main criteria are provided for ship passing command, the working efficiency and accuracy of a command system are improved, and safe navigation of the ship is guaranteed.
本发明公开了一种基于历史数据的控制河段船舶上下水判定方法,属于智能航运与船舶导航应用领域。所述方法包括:以控制河段内船舶AIS历史数据为基础,读取其中的坐标数据和航向数据,以长江电子航道图的航道里程线为分界对航向数据进行统计分析,生成航道里程判定航向。通过该方法,只需将解析过后的船舶位置数据和对地航向数据输入,便可快速判定该船舶的航向为上水或下水,有效简化了船舶航向上下水判定过程,为船舶通行指挥提供主要判据,提高指挥系统的工作效率和准确率,为船舶安全航行提供保障。
