Bridge ship collision prevention monitoring and early warning system

Abstract

The invention discloses a bridge ship collision prevention monitoring and early warning system comprising a detection subsystem used for collecting radar signals, image signals and Beidou positioning signals of coming and going ships and obtaining dynamic information of the coming and going ships; the calculation subsystem is used for predicting surrounding dangerous conditions through a situation awareness theory according to the dynamic information, and generating an early warning signal and a navigation instruction for avoiding the dangerous conditions; the execution subsystem is used for sending an early warning signal and a navigation instruction to the passing ship according to the early warning signal and starting a bridge passive protection device; a data model capable of expressing multi-source, multi-dimension and multi-scale channel elements is designed, a data model conversion scheme is formulated, data geometric position characteristics are analyzed, a risk theoretical model of ship collision bridges and other offshore structures is constructed, a multi-source fusion processing algorithm is developed, and intelligent early warning of ship collision bridges and other offshore structures is achieved.

Description

Technical field [0001] The present invention belongs to the field of bridge construction and the pier protection technology, and provides a bridge anti-boot monitoring warning system. Background technique [0002] With the rapid development of modern foreign trade, the rapid development of port economics and water transportation, but the frequency of malignant accidents that have collided with the bridge has increased year by year, so the bridge anti-collision The system is the key. [0003] At present, there are two major categories: the first category is the passive anti-collision mode, and various flexible energy consumption devices are used, mounted on the outside of the bridge, when hit, reducing the effect of impact, reducing losses; The second category is an active anti-collision mode, installing various sensors or cameras around the bridge, establishing a collision warning system, by monitoring the past ship, caring the route pre-judgment, realizing guidance ship sailing,...

AI Technical Summary

Problems solved by technology

However, the effects are limited, and there is a problem that it is greatly affected by the environment, and it is impossible to distinguish the type and size of the ship.

A single anti-collision method is also prone to mistakes and lead to dangerous accidents, which cannot reflect the generalization of early warning and lacks practicability
