AI Technical Summary

Problems solved by technology

Due to the strong coupling between the state information of obstructions from marine sensors and the collision avoidance route, if it is not considered, the navigation safety of the designed collision avoidance route will be greatly reduced, which will easily lead to collision accidents

Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like figure 1 As shown, an embodiment of the ship collision avoidance method of the present invention, the steps are as follows:

[0036] (1) Obtain the status information and safety boundary of the ship in the channel, and set the initial time as T0;

[0037] (2) Obtain the status information of all obstructions in the channel where the ship is located;

[0038] (3) Based on the status information of all obstructions, eliminate obstructions without collision risk and mark obstructions with collision risk;

[0039] (4) Set the safety boundary of the marked obstacle, and analyze and predict the state information of the obstacle at the time Tn in the future;

[0040] (5) Combining the status information of the obstacle at Tn time and the status information of the own ship, multiple collision avoidance turning ...

Abstract

The invention discloses a ship collision avoidance method, which comprises the following steps of: (1) acquiring state information and a safety boundary of a ship in a navigation channel, and setting initial time as T0; (2) acquiring state information of all obstructions in the navigation channel of the ship; (3) based on the state information of all the obstructions, eliminating the obstructions without collision risks, and marking the obstructions with the collision risks; (4) setting a safety boundary of the marked obstacle, and analyzing and predicting the state information of the obstacle at the future Tn moment; and (5) obtaining a plurality of collision avoidance steering points of the ship in combination with the state information of the obstacle at the Tn moment and the state information of the ship, and correspondingly obtaining a plurality of collision avoidance sailing routes. According to the method, a multi-path solution can be provided for ship collision avoidance auxiliary decision making, the calculation amount is reduced, the efficiency is high, a driver can rapidly know the optimal collision avoidance path in the water area conveniently, and safe navigation of the ship in a complex channel is facilitated.

Description

technical field [0001] The invention relates to a ship collision avoidance method, which belongs to the field of navigation safety. Background technique [0002] Various sensor data used in ships can be directly displayed to drivers through related display devices, but they cannot provide comprehensive information fusion display and collision avoidance suggestions. Drivers need to evaluate collision risks based on subjective experience, especially in the process of entering and leaving ports. A mistake caused a collision with the ship. [0003] With the rapid development of the shipping industry, the density of ships in special navigation areas such as ports and bays has increased significantly, and ship collision accidents have also occurred frequently. Relevant domestic companies, universities and other units have been carrying out research on ensuring shipping safety and reducing ship collision accidents. The most important thing is the research and optimization of vario...
