The invention discloses a grid-based control river reach ship position determination method, and belongs to the field of intelligent shipping and ship navigation application. The method comprises the following steps: on the basis of a calculation range of a control river reach and coordinates of a channel mileage line, gridding the control river reach and establishing an index by combining the actual condition of the control river reach and the advantages of a two-dimensional array, and meanwhile, calculating the position of a grid distance close to the channel mileage line by taking a grid center point as a coordinate, so as to obtain a specific position in the control river reach. Through the method, the grid index can be obtained by performing coordinate change on the longitude and latitude of the ship AIS in the control river reach, and then the specific position of the ship in the control river reach is obtained, so that a powerful basis is provided for ship command in a channel, the working efficiency and the accuracy of a command system are improved, and a guarantee is provided for safe navigation of the ship.

    本发明公开了一种基于网格的控制河段船舶位置判定方法,属于智能航运与船舶导航应用领域。所述方法包括:以控制河段的计算范围和航道里程线坐标为基础,结合控制河段实际情况和二维数组优势,将控制河段网格化并建立索引,同时以网格中心点为坐标,计算网格距离临近航道里程线的位置,进而得到在控制河段中的具体位置。通过该方法,将控制河段内船舶AIS的经纬度进行坐标变化即可得到网格索引,进而得到船舶在控制河段中的具体位置,为航道内的船舶指挥提供有力依据,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。
