Train Delay Analysis And System Design Of High Speed Railway

Benefit from the achievements of railway informatization construction in our country,whether the total scale,high-speed railway operation management level and service quality has been ranked among the top of the world.Nowadays,the transformation of railways from informatization to intelligent construction has become a new direction for railway development in all countries.How to realize intelligent scheduling is the match point in this new round of technology competition.Based on the general train delay theory,this paper subdivides the delay into departure delay,final delay,passing delay,stop delay and section delay according to the different operation modes and operation processes of trains in stations and sections.The reasons and effects of delay under various categories are analyzed in detail.At the same time,the delay recovery is regarded as a special type of delay,and the process and means of delay recovery are analyzed in detail.After that,the visualization method of the index of delay and delay recovery is discussed to provide content support for the high-speed railway train delay analysis system.Secondly,the information platform makes the actual performance data of trains systematically stored,making it possible to study the delay of trains by data-driven.In this paper,based on the actual operation data of Wuhan-Guangzhou high-speed railway,the characteristics of delay are extracted by combining the above delay analysis method,and the prediction model of the recovery location of delay is established by using the GBDT model.After testing,the prediction accuracy of the model is high,and it has a certain generality.The model provides algorithm support for the train delay analysis system of high-speed railway.Then,this paper takes the realization of intelligent scheduling platform as the goal,and designs a train delay analysis system for high-speed railway which integrates the function of delay analysis and delay recovery prediction from multiple aspects of system architecture and system functions.Then,on the basis of the system design,the system is realized,and the method and technical means used to realize the system function are introduced in detail.Finally,the system input data of Wuhan-Guangzhou High-speed Railway is taken as the input data,which verifies the integrity and practicability of the system in function,and proves that the train delay analysis system of high-speed railway has certain guiding value for the realization of intelligent scheduling platform.
