Embodiment

[0049] figure 1 Shown is a flow chart of the method of the embodiment of the present invention, and the equipment involved in the embodiment includes an AIS radio station, an anti-collision warning system and a graphical interface display system.

[0050] The specific implementation steps of the method of this embodiment:

[0051] Step 1: Build a PAD model adapted to the multi-objective situation:

[0052] Such as figure 2 As shown, the ship’s collision avoidance situation element circle (CCPS) is formed by the superposition of several predicted dangerous course areas (PCD), and its radius is the product of the speed V and the minimum safe encounter time TCPAs, which is set to Rs, which represents the trigger collision Warning boundaries. The data structure of each PCD is composed of a start edge C1, an end edge C2 and a color (red and amber), wherein C1 and C2 are arranged counterclockwise. When the own ship is sailing at a safe speed and the course is in the PCD formed ...

Abstract

The invention discloses an AIS information-based multi-target anti-collision warning method, which comprises the following steps: (1) building a predicted area of danger (PAD) model adapting to a multi-target condition; (2) setting DCPAs and TCPAs of a chip; (3) calculating collision prevention factors according to AIS information; (4) carrying out anti-collision warning judgment; and (5) displaying a predicted course of danger (PCD) on a circle of collusion prevention situation (CCPS) of the ship in a superposing manner. Collision prevention correlation factor calculation is carried out by the AIS information; dynamic information can be effectively obtained to calculate correlation factors even if being in a sea area with relatively high navigational density; and collision prevention ship handling intentions of all ships can be timely reflected. The built CCPS model effectively meets the requirements of clearly and simply displaying the collision prevention situation under the multi-target condition; meanwhile, collision warning information can be provided; and a collision prevention decision under the condition of keeping the speed can also be provided, so that convenience is provided for a watch keeper for carrying out ship commanding and dispatching.

Description

technical field [0001] The invention relates to the field of early warning of ships, in particular to a multi-target anti-collision early warning method based on AIS information, which can be applied to the traffic situation assessment of a vessel traffic management system (VTS). Background technique [0002] Collision accidents of ships at sea have brought great harm to people, property and the environment. Research on collision avoidance of ships at sea has been receiving much attention. Such ship scheduling methods are becoming more and more mature, and with the continuous advancement of computer technology and the continuous updating of ship-borne equipment, collision avoidance technology has also been greatly developed. [0003] Usually, mariners judge the collision risk according to the two parameters of DCPA and TCPA, and set the minimum safe encounter distance DCPAs and the minimum safe encounter time TCPAs according to the actual situation, as long as |DCPA|<DCPA...
