The Study And Implementation Of Integrated Simulation Platform For High-Speed Railway Centralized Traffic Control

The Centralized Traffic Control(CTC)is a kind of technical equipment for centralized control and management of signal equipment in a dispatching section,and it is a comprehensive system with complex internal structure,strong correlation and many kinds of external interfaces.With the rapid development of high-speed railway in China,the software upgrading of existing equipment is gradually increasing.A lot of problems need to be settled immediately,such as how to ensure the integrity and stability of the functions of CTC after upgraded,how to improve operators' skills and emergency disposal ability.The platform can promote the maneuverability of the simulation platform,reduce the equipment input,meet the requirements of the simulation test before the software upgrade,and complete the daily training needs of the dispatching operators.Based on the software and parameter of CTC,the simulation module of the related signal equipment in the CTC is realized by using the integrated technology.The integrated simulation platform has realized the running process of virtual train group by studying the traction calculation of train running and the speed control curve of train.The main research contents of this paper include:(1)To study the general structure of the integrated simulation platform,and establish a shared basic data module to realize the comprehensive simulation of CTC related system;(2)In the realization of the basic Computer Based Interlocking(CBI)simulation function,the simulation platform carries on the unified coding to section and station,realizes the integrated simulation of TCC and CBI,and outputs the change state of the signal equipment during the train operation according to the line connection relation and the route state.(3)With the research of interface collection,the simulation platform constructs a unified management and conforms to the relevant interface specification of the interface set,and realizes the connection and data exchange between the simulation system and CTC by standard interface connection.(4)To study and realize the simulation of TSRS,RBC and GSM-R.(5)To study the simulation function of train group operation.According to the basic parameters of the simulation line,the type of simulated EMU,the state of the signal,the temporary speed restriction and the running state of the associated train,the train running curve(including startup plus,inert line and braking curve)is simulated to achieve the reappearance of the train running scene.(6)To study the input of the fault.The system can set up the fault scene in advance or manually,and can determine the trigger time of the fault scene according to the spatiotemporal relation,in order to train and rehearse the driving command and emergency disposal ability of the traffic dispatching and related posts.
