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 a multi-target anti-collision early warning method based on AIS information, comprising the following steps: Step 1: Establishing a PAD model for predicting dangerous areas adapting to multi-target conditions, Step 2: setting the DCPAs and TCPAs of the own ship; Step 3: according to Calculation of collision avoidance elements based on AIS information; Step 4: Judgment of collision avoidance warning; Step 5: Superimposing and displaying PCD on own ship’s collision avoidance situation circle CCPS. The present invention uses AIS information to calculate the relevant elements of collision avoidance, even in sea areas with high navigation density, dynamic information can be effectively obtained and then relevant elements can be calculated, and the avoidance maneuvering intention of all ships can be reflected in time; the CCPS model established by the present invention It effectively meets the requirements of clearly and concisely displaying the collision avoidance situation in the case of multiple targets. At the same time, it can not only provide collision warning information, but also provide collision avoidance decision-making under the condition of maintaining speed, thus providing convenience for the watchman to conduct command and dispatch of ships .

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...
