Research And Design For Train Running Simulation System Based On GIS

Computer simulation technology based on similar principles, information technology, system theory and its application in the field of technology-based professional, established systems model,It is an integrated technology which under different conditions to model the dynamic test.Use computer simulation technology in the computeir,we can repeated the test,with no risk, repeatability and other advantages.Computer simulation technology is a very effective means to study the running of the train.With the rapid development of the railway in China,The train speed and transport density have constantly improved,The ability of railway in china becomes more and more strained.The train diagram prepared by the good or bad will have a direct impact on traffic safety and transport efficiency.Train running simulation system which based on the GIS(Geographic Information System) is a simulation platform,This platform is oriented the entire railway network.Use this system,We can build the entire railway traffic environment and simulate the dynamic process of train group under the entire railway network.including jobs simulation in railway station and train running simulation between two railway stations.By the simulation,It is possible to determine whether the train diagram shows meet all types of safety conditions and constraints, judgment the priority of the trains in crossing and passing,Certificate the feasibility of train schedule,dethermine the arrage of receiving-departure tracks is reasonable and analysis whether the train diagram can adjust in a timely and effective manner after the train was from the diagram.It can supports the decision support for planning and building railway network and optimizating train diagram.Based on the analysis of domestic and international train simulation research and the results from previous studies,This paper that use the computer simulation theories and technology mainly research the train running simulation areas related to simulation methods,model and application technology.Finally,The GIS technology was applicated to the train running simulation. The paper's research emphasized on several aspects as follow:1. According to the existing train running control theory of mechanical energy and train traction theory,combine this simulation study to establish the size of the train running multi-particle mechanics,kinematics and velocity control simulation model;2. According to the the features of discrete simulation system,build a flexible clock control simulations model,enhanced the process of the train running controllability;3. Analysis the development technology of GIS application,according to the the characteristics of the railway equipment,established the stratified management model of the railway stations and sections,build the general basic datas management system for railway running equipments,incluing detail geographic information datas,It is truly reflect the structure of railway network;4. This paper research the process of train running in railway stations,determine the type and flow of station simulation works,explore the algorithm for generating station path and establish the model for station path,establish the relation between the railway station lines and signal equipments,Finally,Study the control strategy for train running in railway stations;5. This paper research the process of train running in railway sections,establish the relation between the line and signal equipments in railway sections and study the control strategy for train running in railway sections;6. This paper analysis and design the train running simulation system based on GIS,establish a common stronger train simulation platform.
