The invention relates to an inland ship navigation collision avoidance method and system, belongs to the technical field of ships, and solves the problems that a navigation aid method in the prior art cannot stably and accurately judge the ship navigation encounter situation and cannot provide collision avoidance suggestions in time. The method comprises the steps that AIS data of a ship and AIS data of other ships in a ship warning area are collected; the AIS data is preprocessed, and the optimized AIS data is obtained; the optimized AIS data comprises ship position, course and navigational speed information of the ship and other ships; according to the optimized AIS data, judging whether collision danger exists between the ship and other ships or not; if the collision danger exists, the meeting water area, the meeting situation, the avoiding responsibility and the meeting stage of the ship and the other ship are judged, and therefore a navigation avoiding strategy is formed and displayed. The working intensity of a driver is effectively relieved, and the safety of ship navigation is improved.
本发明涉及一种内河船舶航行避碰方法及系统,属于船舶技术领域,解决了现有技术中助航方法无法稳定、准确地判断船舶航行会遇态势、无法及时提供避碰建议的问题。该方法包括采集本船以及本船警戒区内他船的AIS数据;对所述AIS数据进行预处理,得到优化后的AIS数据;所述优化后的AIS数据包括本船以及他船的船位、航向以及航速信息;根据所述优化后的AIS数据,判断本船与他船之间是否存在碰撞危险;若存在碰撞危险,则判断本船与他船的会遇水域、会遇局面、避让责任以及会遇阶段,从而形成航行避让策略并显示。有效减轻了驾驶员的工作强度,提高了船舶航行的安全性。
