Method for navigation plan intelligent programming and risk prediction

Abstract

The invention discloses a method for navigation plan intelligent programming and risk prediction. The method comprises the following steps of firstly performing 24-hour inference, obtaining in-future24-hour ship entering and outgoing plane through a network, intelligently programming a navigation plan; predicating an in-future navigation position of a ship; evaluating risks such as collision risk, obstruction offset, ship density, ship width and overlimit, and finally displaying a risk condition according to an electronic sea chart system. The method provided by the invention has advantages of optimizing harbor ship navigation plan programming and traffic organization operation, improving navigation plan management operation efficiency and level, deeply developing navigation potential ofa combined navigation channel, improving traffic organization efficiency of the combined navigation channel and navigation resource utilization rate, and effectively supporting harbor production.

Description

technical field [0001] The invention relates to the field of intelligent arrangement of ship voyage plan, more specifically, it is a method that can automatically and quickly calculate the future position of the ship according to the ship voyage plan and the real-time unplanned ship voyage status in waters, so as to predict the risk and give decision support to VTS personnel. Background technique [0002] With the implementation of the national Beijing-Tianjin-Hebei integration strategy, Tianjin Port and other ports have continued to develop, and multiple waterways have been put into use. Great changes have taken place in port waterways, berths, water depths, navigation standards, and the layout of the navigation environment in port waters. The composition of traffic flow and the entry and exit of ships The Hong Kong traffic organization model is more complicated. The port navigation environment is becoming more and more complex, and the ships entering and leaving the port a...

AI Technical Summary

Problems solved by technology

The compound channel effectively improves the channel passing efficiency and two-way navigation capability, and solves the problem of small ships occupying channel resources. While bringing economic benefits, the port risk increases and cannot be predicted manually

At present, ship voyage planning and ship dynamic conflict coordination are mainly carried out manually, which takes up a lot of energy of the VTS duty personnel, and the efficiency is low. There are even problems such as unreasonable voyage planning and inaccurate judgment of dynamic conflicts. Verification seriously occupies limited high-frequency resources, and even directly affects the efficiency of dynamic arrangements for ships entering and leaving ports
