Problems solved by technology

This type of method has better prediction effect and better efficiency than the first scheme, but it is aimed at the clustering of historical trajectories of all ships, and the actual situation such as the speed of the target ship is not considered in the clustering

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0026] see figure 1 : A ship route prediction method based on ship trajectory clustering, including the following steps:

[0027] 1) see figure 2 , to divide a channel into two areas, one area is the control reach from the upper limit mark to the lower limit mark, and the other area is the matching area outside the upper limit mark or the lower limit mark. Detect if there is a ship entering the matching area by AIS and / or radar.

[0028] 2) When it is detected that a searched ship enters the matching area, according to the past historical data of the ship in the historical database, the historical track of the ship in the control section and the matching area required for clustering is screened out by processing the track data points . The present invention selects the historical trajectory of the target prediction ship based on the MMSI or selects the historical traject...

Abstract

The invention relates to the technical field of Yangtze River digital navigation channels, and provides a ship route prediction method based on ship trajectory clustering so as to improve the accuracyof ship route prediction. The method comprises the following steps of obtaining the ship trajectory data of a target ship in a navigation channel, and pre-processing the missing values, abnormal values and data formats existing in the ship trajectory data; obtaining a high-quality historical route data set of the ship; clustering the historical routes of the predicted ship, extracting typical characteristic routes of the ship sailing in a control reach, matching the current track of the ship with the characteristic routes, predicting the route selected by the ship for passing through the control reach, and calculating the ship passing time based on the predicted route.

Description

technical field [0001] The invention relates to the technical field of digital waterways of the Yangtze River, in particular to a ship route prediction method. Background technique [0002] The controlled river section in the Yangtze River channel is the main area that affects the safety and efficiency of ship traffic. Due to the rapid water flow and narrow bends in the control river section, the current command of the ship passage order by the signal station mainly relies on manual command or the automatic reception of AIS signals through the intelligent auxiliary command system for controlling the passage of ships in the river section, and real-time understanding of ship navigation dynamics, based on first-come-first-served The service principle can determine the order of passage of ships. By improving the accuracy of ship route prediction, the accuracy of transit time prediction can be improved, so as to ensure the safe, efficient and orderly passage of ships through the...
