The invention provides an inland waterway ship situation analysis and prediction method based on AIS big data, and the method comprises the following steps: obtaining the historical navigation data information and the current navigation familiarity information of a ship on an inland waterway through AIS big data, presetting a time interval, calculating the ship navigation time according to the time difference, and carrying out the prediction of the ship situation. A plurality of relative distances between two ships at a plurality of time points in a certain time period in the future are obtained according to the environmental information, traffic information and weather information of the inland waterway, the ship situation is predicted by predicting the latitude and longitude coordinates of the two ships and the minimum meeting time of the two ships at the certain time period in the future, and the relative distances between the two ships are obtained according to the environmental information, traffic information and weather information of the inland waterway. And simulating the state of the ship. The problem that the navigation situation of surrounding ships cannot be judged in an inland waterway in the prior art is solved, and ship collision is reduced.
本发明提供一种基于AIS大数据的内河航道船舶态势分析预测方法,包括以下步骤:通过AIS大数据获取船舶在内河航道上的历史航行数据信息和当前航行熟悉信息,然后预设时间间隔,根据时间差计算得到船舶航行时间,以及未来某个时刻船舶的经纬度坐标,从而得到未来某个时间段内多个时间点的多个两船相对距离,通过预测未来某个时刻两船的经纬度坐标和两船最小会遇时间,从而预测船舶态势,并根据内河航道的环境信息、交通信息以及天气信息,模拟对船舶的状态。本发明解决了现有技术中在内河航道无法判断周围船舶的航行态势,减少船舶碰撞。
