Embodiment 1

[0078] The navigation traffic control method of the present embodiment comprises the following steps:

[0079] ① The real-time and historical position information of the ship is obtained through the sea surface radar, and the position information of each ship is a discrete two-dimensional position sequence x′=[x1 ', 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:

[0080] f ~ ( x ′ ) ...

Abstract

The invention relates to a maritime traffic control method. The method includes the following steps: firstly, acquiring real-time and historical location information of ships through sea surface radar; secondly, at each sampling time, predicating tracks of the ships in the future period of time in a rolling mode according to the real-time and historical location information of the ships; thirdly, acquiring values of sea wind field variables on the basis of the current running status of the ships and a historical position observing sequence; fourthly, on the basis of the running status of each ship and a set security rule set needing to be satisfied when the ships run in the sea, monitoring dynamic behaviors of the ships and providing timely warning information to a maritime traffic control center; fifthly, when the warning information appears, under the premise that physical properties of the ships and sea traffic rules are satisfied, by setting an optimizing indicator function and integrating the wind-field variable values, adopting an adaptive control theory method to perform rolling planning on the collision avoidance tracks of the ships, and transmitting planning results to all the ships to be executed. The tracks are predicated and planned in real time, so that security is good.

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...
