Planning method for ship conflict release

Abstract

The invention relates to a planning method for ship conflict release. The method comprises the steps that firstly, shape tracks, speculated at each sampling moment, of all ships in a future time period are acquired through a maritime traffic control center; sequences are observed on the basis of current operation states and historic positions of the ships, and sea area wind field variables are obtained; then at on the basis of the operation states of all the ships and a set safety rule set which is required to be met by the ships in the sea area during the operation each sampling moment, when a condition which might violate safety rules occurs among the ships, dynamic behaviors of the ships are monitored, and timely warning information is provided for the maritime traffic control center; finally, when the warning information occurs, on the premise that ship physical properties and sea area traffic rules are met, rolling planning is performed on a ship collision avoidance track with a self-adaption control theory method by setting an optimization indicator function and infusing wind field variables, and a planning result is transmitted to all the ships to be executed.

Description

technical field [0001] The invention relates to a sea area traffic control method, in particular to a planning method for ship conflict relief 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 efficie...

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
