Problems solved by technology

Compared with ship-bridge collision accidents on inland waterways, collisions between ships and cross-sea bridges usually cause greater economic losses and more serious environmental pollution
Finally, the existing ship collision bridge risk models serve the bridge design, and the result given is the overall annual ship collision frequency of a bridge

Abstract

The invention discloses a risk prediction-based ship collision early warning method for a cross-sea bridge, which is used for predicting the risk of collision between a ship entering the sea area of ​​the bridge area and a bridge pier. Including determining the scope of the risky sea area; obtaining the real-time position of the ship to form the sample data of the ship's track; training the dynamic regression model with the ship's track as the sample data, and predicting the position of the ship at the next moment; predicting based on the relative position of the ship and the pier The risk probability of ships colliding with bridges; setting up risk thresholds and taking emergency measures for high-risk ships; updating the dynamic regression model in real time to maintain monitoring and early warning of low-risk ships that have not yet safely crossed the bridge. The invention overcomes the limitations of the prior art methods in the field of ship collision protection for cross-sea bridges, and can effectively predict the risk of ships colliding with bridges, thereby protecting the safety of ships and bridge structures.

Description

technical field [0001] The invention relates to the field of ship collision protection for cross-sea bridges, in particular to a risk prediction-based ship collision warning method for cross-sea bridges. Background technique [0002] In recent years, the increasing construction of cross-sea bridges and the vigorous development of marine transportation have led to a rapid increase in the number of crossings of ships and bridges within the sea area of ​​the bridge area. The safety of cross-sea bridges is facing the serious threat of ship-bridge collision accidents. In recent years, there have been a number of cross-sea bridge ship collision accidents at home and abroad, such as the 2018 Kansai Airport ship collision accident in Japan and the 2019 Gwangan-ri Bridge ship collision accident in South Korea, which caused obvious damage to the bridge. [0003] At present, the research of ship collision with bridge mainly focuses on the identification of structural damage after coll...
