Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] When traditional radar equipment judges the collision distance, time or other related indicators of ships, the data processing algorithm has limitations and can only deal with the problem of straight-line collision; the data mining method needs to establish a knowledge base; the collision time algorithm is complex and the calculation cost is high. Not easy to achieve.

[0044] In order to solve the above problems, the present invention will be described in detail below in combination with technical solutions.

[0045] Such as figure 1 As shown, the space-time sensing ship collision risk intelligent early warning m...

Abstract

The invention belongs to the technical field of collision warning of ships, and discloses a space-time-aware ship collision risk intelligent warning method, which judges the target ship for collision warning and the surrounding ship objects set according to the area of ​​the target ship and the positions of other ships Which of the ships in A is directly included in the field of the target ship for collision detection, output the set of ships that may collide with the target ship; the risk level of the ship that may collide. The present invention abstracts ship information into an ellipse, and further abstracts it into a rhombus for collision warning during collision warning calculation, which greatly reduces the calculation amount of collision warning and shortens the response time of the warning system; abstracts and simplifies the collision warning algorithm into an ellipse. The intersection greatly reduces the difficulty and complexity of calculation.

Description

technical field [0001] The invention belongs to the technical field of ship collision early warning, in particular to an intelligent early warning method of ship collision risk based on space-time perception Background technique [0002] In the context of world economic globalization, inland navigation, as an important basic link, plays a vital role in transportation. With the increasing traffic pressure on inland waterways and the rapid development of the AIS system, the management and monitoring of water traffic by the maritime supervision department has changed from post-event emergency to pre-warning. Ship collision warning technology is an important part of the development of ship intelligent information. The development of the technology can greatly improve the safety of marine transportation. [0003] Compared with traditional radar equipment, AIS equipment has the advantages of being less affected by terrain and weather, high positioning accuracy, etc., and can prov...
