Design And Implementation On Simulation Of Centralized Traffic Control Station Subsystem

Centralized Traffic Control System is an intelligent train operation dispatching command system of integrated computer,network communication and other technologies in the new century,which is based on the national conditions of our country and draws on experience of foreign railway dispatching.CTC is referred to as Centralized Traffic Control System in this thesis.CTC station subsystem is the basic node in terms of decentralization and automation's implementation.The thesis is supported by the project"Experiment platform of Beijing-Shanghai high-speed CTCS-3 level railway train control system".The Simulation software is designed to simulate and evaluate CTC station subsystem's functions of scheduling and operation process management.A good demo function is applied to understand system structure and information of flow transmission in practical applications.The function of the fault setting can be applied to the teaching-aided.Based on the research background and status of CTC,both domestic and overseas,the structure and function of the actual station are analyzed in the thesis.Function is designed and implemented by modules according to architecture and functional requirements of the system.The design of function is divided into the interface display module,the mode conversion module,the train operation module,the shunting operation module,the communication module and the database module.The specific functions between stations of Beijing South Railway Station,Nanjing South Railway Station,and Shanghai Honoria Railway Station are realized.Plans or dispatching orders are received and analyzed by autonomic machine,then a variety of route triggering methods are used to realize self-discipline operation or manual operation.The operation rights of the train operation and the shunting operation under different modes are realized.Coordinated operation of train operation and shunting operation are realized.Scheme of manual route selection and plan consistency checking is adopted to reduce the probability of manual selection and achieve the safety control in the thesis.Communication interruption,route conflict,route malfunction and other fault setting functions can be completed.The route information,the alarm information and the locomotive communication database are set up to facilitate the historical inquiry,and it can be used to teaching-aided.At the end of the thesis,the simulation platform is used to test the whole system of autonomic machine,station management terminal and center of CTC,interlocking,radio block center and train,so that the software meets the core functional requirements of the CTC station subsystem by the white box test.Finally,several rationalization proposals are put forward for the problems existing in the CTC station subsystem.
