The invention relates to the field of intelligent shipping and ship draught real-time detection, in particular to a ship draught real-time detection method and system. The method comprises the steps that an RTK base station is arranged on the water surface, and satellite data are observed and received through the RTK base station; a plurality of RTK mobile stations are fixed on the ship, and satellite data are observed and received through each RTK mobile station; selecting the time of one RTK mobile station as the standard time, and calculating the advance time of the RTK base station and other RTK mobile stations relative to the standard time; calculating the coordinates of the RTK base station and each RTK mobile station by using the calculated lead time and the satellite data received by the RTK base station and each RTK mobile station; and calculating the draft of the ship by using the coordinates of the RTK base station and each RTK mobile station. The ship draught can be dynamically detected in real time, and the ship navigation safety is guaranteed.
本发明涉及智能航运、船舶吃水实时检测领域,特别涉及一种船舶吃水实时检测方法及系统。本发明方法包括:在水面设置RTK基准站,并通过RTK基准站观测和接收卫星数据;在船舶上固定多个RTK移动站,并通过每个RTK移动站观测和接收卫星数据;选择其中一个RTK移动站的时间为标准时间,并计算RTK基准站和其他RTK移动站相对于标准时间的超前时间;利用计算的超前时间,以及RTK基准站和每个RTK移动站接收的卫星数据计算出RTK基准站和每个RTK移动站的坐标;利用RTK基准站和每个RTK移动站的坐标计算船舶的吃水深度。本发明能够实现对船舶吃水进行动态实时检测,保障船舶航行安全。
