Coordination Method Of The High-speed Railway Train Diagram And The EMU Routing

As China's "eight vertical and eight horizontal" railway network to be built.High-speed railway has become a business card for China to lead the world.With high-speed rail than the existing line of unique advantages of high-speed railway has become an important part of our people travel essential.Railway traffic organization is the core of rail transport.Train diagram and EMU routing are the most important technical documents for high-speed railway operation organizations.The train operation diagram guides the daily operation of the railway to ensure the safety of the railway.EMU routing provide power for high-speed railway operation.High-speed railway train diagram and EMU route preparation are the key points and difficulties of railway traffic organization.The two are related to each other and to each other.The development of high-quality train diagram and EMU routes will help to improve the social and economic benefits of rail transport.Therefore,It is of great significance to study the train diagram of high-speed railway trains and the coordination of EMUs.This paper uses the principle of synergy to conduct collaborative research on the high-speed railway train operation diagram and EMU route.The main research contents are as follows:(1)Introduce the high-speed railway train diagram and the basic theory of EMU routing.On the basis of the existing research results,analyze the basic theory of high-speed railway operation characteristics,train operation planning,compilation principles,processes and ideas,basic elements,and the difference between high-speed rail and existing lines.Summarize the basic theories such as the continuation and overhaul of EMUs.(2)High-speed train diagram in the preparation of EMU Routing collaborative solving mechanism.Using the principle of synergy,this paper analyzes the correlation between high-speed railway traffic organization system coordination,high-speed railway operation diagram and EMU routing,The system compares and analyzes the three phases of the high-speed railway train diagram and the EMU routing preparation: adaptive phase,saturated phase and tension phase.And elaborate on two methods of preparation in the case of tension: the integrated collaborative programming method and the hierarchical collaborative programming method.(3)Establish a collaborative programming model.In the operation diagram,the deviation between the originating time and the initial time domain is the smallest,the total travel time is minimum and the balance is the best.For the EMU route,the minimum total time for the EMU reentry station,the shortest EMU connection time is the largest and the minimum number of tight routes are the targets.Consider the relevant constraints for compiling time and space.It is finally determined that this paper uses a hierarchical collaborative solution method.(4)According to the hierarchical collaborative solution method,a collaborative programming algorithm is designed.When designing the train diagram algorithm,three key functions of conflict detection and conflict resolution,stop time adjustment and initial timing adjustment are implemented,and the simulated annealing algorithm is nested,and finally realized by C++ programming.When designing EMU routing algorithm,In the diagram on the basis of the optimized by notation points to fetch dense,compact connection method by the principle of first come,first made to develop standard routing.On the basis of the standard roution,the compact dislocation method is used to obtain the tight road.The feedback adjustment method of the operation line redundancy time is used to adjust the operation line,so that the tight routing becomes a standard roution,to save the EMU,and finally realize the layered collaborative preparation.(5)Take Beijing-Shanghai high-speed rail as an example to verify the model and algorithm.Taking the Beijing-Shanghai high-speed railway as an actual case,using the basic data such as timetables and various parameters,the train operational diagram,the EMU standard roution and the tight route are prepared,and feedback adjustment is made.Finally,the Beijing-Shanghai high-speed railway train operation diagram and route diagram will be establishmented.The preparation of the final results of the analysis.The example shows that the model and design algorithm established in this paper are feasible and practical.
