The CTCS3 Simulation And Test Platform

Chinese high speed railway is now developing rapidly. Train operation safety and efficiency can only be guaranteed by high performance train control system. According to the experience of European Train Control System(ETCS), Chinese railway has proposed the Chinese Train Control System. Right now, the CTCS2 system is used for the passenger dedicated high speed line, and the research on the CTCS3 system is urgently needed. So it is quit necessary to establish a simulation and testing platform to support the research of CTCS3 system.The focus of this paper is to research on the Train Operation Simulation Subsystem (TOSS) which is a part of the CTCS3 simulation and test platform. The work of this paper is summarized as following:â–  Analyzed the architecture of the CTCS3 simulation and testing platform, as well as the function and interface requirement of the subsystem..â–  Analyzed the software architecture of the TOSS, as well as the function of the modules, and the interface requirement between TOSS and other simulation subsystems.â–  Designed and realized the basic function of the TOSS, including data transmiting by balise, train positioning, display of track circuit occupancy, train dynamic despatching by multi-train simulator, definition of database and data dictionary.â–  Designed and realized the communication interface between TOSS and other simulation subsystems, including the balise telegram,SSP etc. for the on-board subsystem, and the available balise ID and track parameters for RBC and so on.â–  Designed the MMI of TOSS, providing a platform to demonstrate the principle of the CTCS3 simulation and test platform.â–  The normal communication and data exchange among different simulation subsystem is realized, and the function of the TOSS is validated.
