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

[0077] The navigation traffic control method of the present embodiment comprises the following steps:

[0078] 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 present invention relates to a navigation traffic control method, which includes the following steps: first, the real-time and historical position information of the ship is obtained through the sea surface radar; Then, based on the current operating state of the ship and the observation sequence of historical positions, the value of the wind field variable in the sea area is obtained; and based on the operating state of each ship and the set of safety rules that the ship needs to meet when operating in the sea area, Monitor the dynamic behavior of the ship and provide timely warning information for the maritime traffic control center; when the warning information appears, on the premise of meeting the physical performance of the ship and the sea area traffic rules, by setting the optimization index function and integrating the value of the wind field variable , using the adaptive control theory method to carry out rolling planning for ship collision avoidance trajectories, and transmit the planning results to each ship for execution. The present invention predicts and plans the track in real time, and has good safety.

Description

technical field [0001] 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 [0002] 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 conflict resolution is a key technology in the field of navigation. A safe and efficient solution is of great significance for increasing the flow of ships in sea areas and ensuring maritime safety. [0003] In order to improve the navigation efficiency of sh...
