The Study Of Urban Rail Transit Train Operation Simulation System

With the rapid development of urban rail transit into the network operational phase,the operational safety management and troubleshooting become critical core issues.Presenting operational status with computer-based and practical simulation technology, andrehearsaling operating plan model-based become an important issue.Through the analysis of the characteristics of the existing operational programs, thispaper designed typical run line towards Site form and foldback form. Through the study ofurban rail transit signal theory, the train control theory, scheduling decision theory,database management technology, object-oriented programming techniques, and local areanetwork communication technology, realized construction of the track circuit and wirelesscommunication-based train operator scheduling decisions. With the automatic train into thepath generation algorithm and develop communication protocols, achieving the design ofoperational plan and interlocking relationship between route and signal. And networkmanagement and database technology is in-depth studied to complete the design of dataexchange and server software. Finally by means of simulation, achieving train operation,dispatching system simulation, processing the train within the station, open and closesignal, locking and unlocking the track, the process of acceleration and deceleration control,as well as normal and common variety under normal circumstances.This system is better than the past system, which can only be a single simulation ofurban rail traffic signal interlock defects, true representation of the scene of the operatingenvironment operating equipment and procedures, and programs designed for highefficiency operations support and fault drills.
