Active ship impact prevention monitoring system for bridge and method thereof

Abstract

The invention relates to an active ship impact prevention monitoring system for a bridge and a method thereof. The system comprises a video monitoring device, a laser height measuring device, an alarm device, a main control computer and a centralized control center. The video monitoring device is used for finishing yawing monitoring on ships in navigation. The laser height measuring device is used for finishing height monitoring on the ships in navigation. The main control computer is used for finishing storage and processing of operation states of the ships in navigation. The centralized control center monitors whether to transmit early-warning information or other information to the ship, thereby realizing remote monitoring to ship navigation. According to the system and the method, real-time data of the ship are combined with a software algorithm, thereby realizing higher early-warning sensitivity, and compensating function limitation and efficiency limitation based on a traditional ship traffic management system and a passive ship impact prevention facility. The system and the method according to the invention perform functions of realizing full monitoring automation, reducing workload of a person and ensuring high accident early-warning reliability. The system and the method further have advantages of higher practicability, longer detecting distance and longer emergency reaction time.

Description

technical field [0001] The invention relates to a bridge active anti-ship collision monitoring and early warning system and method. Background technique [0002] At present, the research on active collision avoidance technology and methods of bridges in navigable waters is still blank or in its infancy, and there is no applicable design code or standard. The existing bridge anti-ship collision technology at home and abroad is mainly based on the passive anti-ship system and the vessel traffic management system (VTS). [0003] At present, the passive anti-ship collision system mainly ensures that the bridge has sufficient resistance and does not collapse after a ship collision event by improving the resistance of the bridge and adding buffer devices. This method has reduced the damage to the bridge caused by the ship collision accident to a certain extent, but it cannot avoid the occurrence of accidents, and the cost of bridge construction is too high, which is very uneconom...

AI Technical Summary

Problems solved by technology

This method reduces the damage to the bridge caused by the ship collision accident to a certain extent, but it cannot avoid the occurrence of accidents, and leads to the high cost of bridge construction, which is very uneconomical and reasonable

The information exchange methods of the Vessel Traffic Management System (VTS) mainly use high-frequency wireless telephone, fax, VHF (Very High Frequency) communication, etc. The system information exchange process is repetitive and cumbersome, and the work efficiency is extremely low

At the same time, the telephone consultation of a large number of ship drivers asking for information will affect the normal work of the personnel on duty, which will cause traffic safety problems
