A ship-bridge collision avoidance active anti-collision intelligent early warning system and method

Abstract

The present invention provides a ship-bridge collision avoidance active anti-collision intelligent early warning system, comprising: a ship navigation information collection module, which collects and broadcasts dynamic and static information of the ship; a ship-bridge collision risk measurement module, which is based on the ship's dynamic information, The ship-bridge collision risk judgment model calculates the ship-bridge collision risk in the bridge area waters; the collision risk intelligent early warning module, according to the ship-bridge collision risk in the bridge area waters, provides collision avoidance for ships in the bridge area waters that are prohibited from navigating Early warning, anti-collision early warning for ships that bring high collision risks to bridge piers; chart information generation module, based on dynamic information and static information of ships, and pre-collected geographical information of bridge waters to generate electronic charts, and display them on the electronic charts The prohibited waters in the bridge area, the dynamic information and static information of the ship, and the early warning level of the ship. The present invention also provides an intelligent early warning method for ship-bridge collision avoidance and active collision avoidance.

Description

technical field [0001] The invention relates to the technical field of ship navigation active collision avoidance, in particular to a ship-bridge active collision avoidance intelligent early warning system and method. Background technique [0002] In recent years, with the rapid development of my country's economy, a large number of bridges across rivers and seas have been built on waterways. The density of bridges has been increasing, the level of waterways has gradually improved, the flow of ship traffic has increased rapidly, and accidents of ship collisions with bridges have occurred from time to time. International research on ship-bridge collision problems began in the late 1960s. The collapse of the Sunshine Bridge in the United States in 1980 attracted great attention from the international engineering community. In 1995, the shipping industry organized the first international special study on ship-bridge collision issues——PIANC established the 19th working group ded...

AI Technical Summary

Problems solved by technology

Passive anti-ship collision is mainly to protect the safety of bridges, without considering the protection of ships

In addition, after the passive anti-ship collision device is installed, it will have a certain impact on the navigable area and navigable route of the water area
