Description
Technical field
The present embodiments relate to bridge zone ship's navigation active collision prevention technical field more particularly to a kind of bridge zone ship's navigations
Anti-collision early warning system.
Background technique
Bridge construction and shipping business development, very important status is occupied in the national economic development.People are enjoying
While by bridge construction be that economic liftoff bring is huge convenient, also have in face of because bridge to build bring various tired
Border.These predicaments include: cause ship navigable waters navigation clear span, clear height limited because bridge pier occupies original navigation channel waters, thus
Directly or indirectly cause safety of traffic on water accident or causes security risk；Because bridge build change original water channel flow field it is special
Sign, so as to cause ship in bridge waters navigational difficulty, is further increased the risk of ship collision bridge pier.Ship bridge
Collision accident once occur, caused by loss will can not estimate.It is light then cause ship, bridge damage, it is heavy then cause ship ruin bridge collapse with
And great casualties and environmental pollution accident.Pertinent literature and report are made a general survey of, people are it is not difficult to find that great bridge touches both at home and abroad
The accident of hitting happens occasionally.
At abroad, the 19th work group of Permanent International Association of Navigation Congresses the most famous by rise occur Europe,
The vessel bump bridge accident data for saying the ground such as sheet, the U.S. is for statistical analysis, the reason of vessel bump bridge accident is attributed to three categories: first
Major class is human error, such as carelessness, manipulation fault；Second major class is mechanical breakdown, such as host daughter-in-law fire, steering engine failure, fleet
Disconnected cable etc.；Third major class is severe natural environment, such as bad weather, great flood.The analysis the result shows that, by human error,
The ratio that one bridge collision accident of ship accounts for total number of accident caused by mechanical breakdown and extreme natural environment is respectively 80%, 8%,
12%.At home, someone unites to the vessel bump bridge accident that rises occurred over 40 years in more than the ten seat Yangtze Bridge of Changjiang River Trunk Line
Meter analysis, the results showed that, the ratio that the vessel bump bridge accident as caused by above-mentioned three big reasons accounts for total number of accident is followed successively by 78%, 6%
With 16%.It can be seen that the either external or domestic vessel bump bridge accident occurred, human factor is all first to cause the accident
Big reason.
The Anticollision Measures of bridge generally can be divided into two ways: active anticollision and passive anticollision.Passive anticollision is to pass through bridge
The reinforcement of pier itself or safeguard procedures threaten to resist the shock of ship, or acoustic-optic alarm warning is installed on bridge
Navigation safety.Currently, domestic and international a large amount of scholar is made that a large amount of research and effort in bridge-collision-avoidance field, but it grinds
Study carefully and focuses on the researching and designing of reinforcement and bridge pier protection guard to bridge pier body structure, to the risk of ship collision bridge
On causation analysis after Probability Study and collision accident generation, these researchs belong to the scope of passive collision prevention.Not preferably
Concern Ship Controling personnel itself factor.Comparatively, passing through effective early warning pre-control means before collision does not occur
Prompt in the key operation of crucial moment ship is carried out with guidance to achieve the effect that active collision prevention to marine navigator, then is
More meaningful research topic.
Active anticollision refers to through navigation management to ship and ship trajectory intervention, avoids the generation of vessel bump bridge accident,
Active anticollision is positive precautionary measures.Existing active Anticollision Measures have been summed up two classes: (1) setting up bridge mark.Pass through
Visual beacon, such as label, night lights in the daytime；Acoustic signal, such as fog signal；Indicator marker, such as radar reflector and radar response
Device etc., guidance shippping traffic see clearly pier location, select correct air route, and safety is passed a bridge.This method is simple and easy, but by meteorology
Condition influences big, and when poor visibility is invalid.Although indicator marker is not influenced by meteorological, visibility, certainly due to indicator marker
Technical limitation existing for body cannot get a desired effect.(2) safety monitoring system is established.Pass through traffic control (VTS) thunder
Cooperate up to monitoring, video monitoring early warning system and very high frequency telephone, bridge Its Adjacent Waters and the ship for driving into bridge are implemented for 24 hours
Artificial monitoring；Gap bridge ship is reminded in time, is taken measures early.Its main feature is that the navigation state of shippping traffic can be monitored in real time
Gesture finds accident potential early.But it is at high cost, the degree of automation is low, when shippping traffic peak, is difficult to monitor.
Some scholars are also made that some researchs in bridge active anticollision field or are installed on bridge merely both at home and abroad at present
Collision prevention is realized using laser, infrared or visible light monitoring means or using machine vision image processing techniques on beam, it is pre-
Alert information simultaneously fails to give notice driver's cabin, and early warning effect is limited；Collision prevention is realized by the way that equipment to be installed on ship, but it is neglected
A critically important problem has been omited, has been exactly that there is uncontrollability by the ship of bridge, inland navigation craft, domestic and international seagoing vessel are possible to
Pass through, can not accomplish by need anticollision device is respectively mounted by the ship of bridge.In addition, relevant maritime sector be
The accident that ship occurs just arrives scene and collects information evidence obtaining, and the accident investigation evidence obtaining time is long, is not easy to manage.
