Active anti-ship collision monitoring and early warning system for bridge

Abstract

The invention provides an active anti-ship collision monitoring and early warning system for a bridge for tracing ship tracks of all ships in a target channel for early warning ship collision of the bridge in the target channel actively. The system is characterized by comprising a plurality of monitoring video acquiring devices and a track tracing device, wherein each monitoring video acquiring device is provided with a video collecting part and a collecting side communication part. The track tracing device is provided with a nerve network storage part storing a nerve network model, a target ship acquiring part for acquiring the ship position of the target ship, a coordinate acquiring part for acquiring coordinate values of the ship according to the ship position, a ship track acquiring part for acquiring the ship track and a route speed of the ship according to the coordinate values of the ship, a ship track predicting part for acquiring a predicted track, a predicted speed, a bridgearriving time and probability distribution of passing positions according to the ship track and the route speed, and a ship collision early warning part for acquiring the ship collision probability according to the bridge arriving time and the passing positions and sending alarm.

Description

technical field [0001] The invention relates to the field of structural safety and navigation safety monitoring, in particular to a bridge active anti-ship collision monitoring and early warning system Background technique [0002] The ship collision accident has a great impact on the safe transportation of bridges and roads, people's life and property, and even the development of social economy. With the continuous economic growth and the increasing demand for transportation facilities, the number of bridges in my country is increasing. The construction of large bridges can relieve traffic pressure and promote land transportation. However, for water ships, bridges are artificial obstacles. When ships sail under the bridge, there is a danger of colliding with bridge piers or bridge span structures, which poses a threat to the safety of bridges and ships, and at the same time poses a threat to the safety of waterways and land traffic. normal functioning is also a threat. ...

AI Technical Summary

Problems solved by technology

Most of the existing video monitoring methods for bridge collision avoidance rely on target detection technology based on background subtraction, with poor stability and non-intelligent shortcomings, and key technologies such as target navigation status recognition and track tracking prediction have not been paid attention to.
