Research On Dangerous Zoning Method For Bridge Anti-ship Collision Warning Bridge Area

In recent years,with the rapid development of China's economy,the number of ships has not only increased,but also has a large-scale trend;with the rapid development of the shipping industry,infrastructure construction has also developed rapidly,and the number of bridges across the channel has also increased.You are getting more and more.These factors not only have certain limitations and adverse effects on the navigation of the ship,but also increase the possibility of bridge collision.If a bridge collision occurs in the bridge area,shipping may be interrupted,the bridge collapses,and the water and land traffic will have an adverse effect.Worse,it may endanger people's lives.Therefore,ensuring the safe navigation of the ship in the bridge passage and reducing the collision between the bridge and the bridge is an urgent problem to be solved.Since the bridge passive anti-ship collision is passive protection,it can not effectively avoid the collision of bridges and bridges,which has certain limitations.Therefore,this paper studies the active anti-collision warning of bridges,mainly doing three aspects:First,a dangerous division of the waters of the bridge area was carried out.After comprehensive statistical analysis of the relevant data of the bridge environment,in order to ensure that the ship does not collide with the bridge,according to the ship braking theory of brake braking and rotational braking,the ship brakes and the cycle calculation.The braking distance of the two braking modes,according to the two braking distances,the three-level hazardous area is divided into ships of different tonnages and different speeds to sail in the waters of specific bridges;The second is the hazard classification of ships sailing in the bridge area.For specific bridges and ships,Midas Civil and Ucfyber software are used to calculate the ship's own ship impact resistance and ship impact.After comparing the bridge resistance and the ship impact force,the collision damage degree of the ship to the dock is taken as the standard.Ships entering the bridge area have a three-level hazard level.Thirdly,based on the three dangerous areas of the bridge area and the three hazard levels assigned to the ship,after scientific analysis and judgment of the ship collision risk,a risk warning matrix is constructed to enter different dangers of different ships.region..Different levels of warning messages are issued to enable the ship to take appropriate anti-ship collision measures in advance.Through the calculation and evaluation of various quantitative and qualitative aspects of bridge areas and ships,a corresponding early warning framework is established to realize dynamic early warning of different ships in different bridge areas,and an anti-ship collision active early warning system is developed.And establish future security.The water police system has laid the foundation and is of great significance in preventing and reducing the occurrence of ship collision accidents and ensuring the safety of people's lives and property.
