Problems solved by technology

Although this kind of equipment greatly reduces the load of manual monitoring, it does not have the function of automatic conflict resolution of the ship
For the problem of ship conflict resolution, the current processing methods mainly include two types of schemes: geometric deterministic algorithm and heuristic intelligent algorithm. Form” plans the release trajectory for conflicting ships, resulting in poor dynamic adaptability and robustness of each ship’s release trajectory

Embodiment 1

[0079] A navigation control method based on a rolling planning strategy in this embodiment includes the following steps:

[0080] ①Obtain the real-time and historical position information of the ship through the sea surface radar, and the position information of each ship is a discrete two-dimensional position sequence x'=[x 1 ',x 2 ',...,x n '] and y' = [y 1 ',y 2 ',...,y n '], by applying wavelet transform theory to the original discrete two-dimensional position sequence x'=[x 1 ',x 2 ',...,x n '] and y' = [y 1 ',y 2 ',...,y n '] for preliminary processing, so as to obtain the denoising discrete two-dimensional position sequence x=[x 1 ,x 2 ,...,x n ] and y = [y 1 ,y 2 ,...,y n ]: For a given original two-dimensional sequence data x'=[x 1 ',x 2 ',...,x n '], which are approximated by linear expressions of the following form:

Abstract

The invention relates to a navigation control method based on rolling planning strategies. The method includes the following steps: obtaining real-time and historical position information of ships through sea surface radar; at each sampling time, carrying out rolling prediction of trajectories of the ships within a future period of time according to the real-time and historical position information of the ships; observing sequences on the basis of current running states and historical positions of the ships, and obtaining a value of a sea wind field variable; on the basis of the running states of the ships and a safety rule set the requirement of which a set ship needs to meet when the set ship is running within the sea, monitoring dynamic behaviors of the ships and providing timely warning information to a sea traffic control center; and when the warning information appears, adopting an adaptive control theoretical method to conduct rolling planning for ship collision-prevention trajectories by setting an optimization index function and merging the wind field variable value under a condition that the ship physical performance and sea traffic rules are satisfied, and transmitting a planning result to the ships for implementation.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201410849264.4, the title of the invention is "A Method for Navigation Traffic Control", and the application date is: December 30, 2014. technical field [0002] The invention relates to a sea area traffic control method, in particular to a sea area traffic control method based on a rolling planning strategy. Background technique [0003] With the rapid development of the global shipping industry, the traffic in some busy sea areas is becoming more and more congested. In sea areas with dense and complex ship traffic flow, the control method of sailing plan combined with manual interval allocation for the conflict between ships can no longer adapt to the rapid development of the shipping industry. In order to ensure the safe separation between ships, the implementation of effective conflict deployment has become the focus of sea area traffic control. Ship conf...
