Design And Development Of Influences Analysis And Deduction System Of Station Construction

Since the 21 st century,with the vigorous development of the national economy,the railway industry has received more and more attention.With the implementation of the “Belt and Road”,the operation speed of state-owned railways has been continuously improved,and the construction of high-speed railways has taken root in the world.In order to achieve the goal of safely operating trains under high-speed conditions,railway workers around the world are making unremitting efforts.However,the high density and high speed of train operation will also cause a certain degree of damage to the railway facilities and equipment,which poses a safety hazard to the operation of the train.In order to ensure the safety of the train and the personal safety of the passengers,it is necessary to repair and maintain the hidden parts.Through the observation of the status quo of domestic construction to the organization of train operation’s impact analysis,we found that due to the lack of process,system and information analysis and management tools,a series of safety problems such as the organization of the train operation and the analysis of leakage factors during the construction period have occurred.These problems will have a certain impact on the safety of train operation,traffic organization and management and transportation capacity.In China,skylight constructions at railway station need to draw up construction plans.The corresponding staff manually infers the scope and extent of the construction according to the construction plan.Considering that there are certain limitations in manual judgment,it is possible to cause misjudgment and other phenomena.Therefore,in order to improve the carrying capacity of station under construction conditions and ensure the safety of railway station’s transportation,it is necessary to develop a construction influences analysis and deduction system of station construction.Firstly,this paper analyzes the current situation of skylight construction in railway stations in China,summarizes the shortcomings of the existing construction scheme deduction method in actual transportation production,and puts forward the research purpose and significance of the paper and the necessity of developing construction influences analysis and deduction system of station construction.Secondly,based on the large collection and analysis of the construction source data of each station,this paper summarizes the common construction types,and designs a construction dictionary table with the construction standard terms and equipment information corresponding to the standard terms.Through the in-depth study of the Levenshtein Distance algorithm,combined with the construction dictionary table designs the construction plan keyword extraction algorithm based on the Levenshtein Distance algorithm.The purpose is to convert the construction plan into computer readable device information content.Then,based on the knowledge of computer graphics theory,this paper uses the drawing software to draw the layout map of the station signal,and uses the generated device relationship data to model the topology of the station graph directed graph.Finally,this paper automatically generates the approach node pair according to the principle of signal matching at the beginning and terminal of the approach.According to the depth-first search algorithm of the graph,searching the route information from the beginning to the terminal is stored in the interlocking route table.By searching for which way in the interlocking access table of the locking device,the marking and display of the influence range of the construction deduction is completed.
