Research Of Database In Urban Rail Transit Traffic Capacity Simulation System

With the development of rail transport in China, Transport capacity and transport efficiency of urban rail transport system has become the most important indicators. It is significant to improve the efficiency of rail transit, by setting up a unified and integrated urban rail traffic database system on the basis of field data research and literature survey, provide accurate, consistent, reliable data for the distributed simulation and evaluation system.First, this paper analyzes the simulation system and database technology development at home and abroad, thus demonstrating the significance to establish rail transportation simulation system and the significance of database systems. And transport capacity of simulation system design objectives, design structure, the simulation environment are described, and the simulation system database are highlighted.The database system data model was set up by rail transport capacity simulation database needs analysis, and give a brief introduction about the physical realization of the database.Based on the above analysis, describe in detail how to build B/S structure database management systems by using PHP+MYSQL+Apache, including database systems functional design, architecture design, implementation, data input and output and coupling interface, and on the basis of the study RailML established XML-based train control system data exchange interface.On the basis of the study of data model,establish the legitimacy of a train control system validation rule, ensure the accuracy of the output data of the database.Finally, the paper summarizes the work, raised the need to further improve and in-depth study of the problem...
