Design And Implementation Of CTCS3Onboard Simulation System In Coupling System

To ensure the correctness and rationality of railway related device, and provide predictive information for the relavent researchers and train operation personnel, a coupling simulation system which orients the high-speed railway’s full life-cycle and can simulate whole operation circumstance of high-speed railway should immediately be developed. Train control system functions as the nerve center of the high-speed railway, is very important to keep safe in the running of high-speed train, and improve the transporting efficiency. Today, we Chinese scientists are committed to the development of CTCS(China Train Control System)train contro system. Because of its unique advantages, communication based CTCS3train control system is the focus of the research. Therefore, the establishment of CTCS3simulation system, which can carry out co-simulation in the coupling simulation system is particularly important.According to the technical specification of CTCS3train control system, and combining the reqirement of high-speed railway’s coupling simulation system, this paper developed the CTCS3onboard co-simulation subsystem. On the basis of the display specification of CTCS3onboard Driver Machine Interface, onboard simulation system interface was designed and realized; Trains were protected with the train protection curve derived from train braking mode curve which is calculated by genetic algorithm; The interface protocols between CTCS3onboard subsystem and other subsystems such as Automatic Train Operation, High-speed Train Dynamics and Tractive Drive subsystems were designed; Interface between CTCS3onboard subsystem and CTCS3wayside subsystem was also designed and implemented based on the definition and application principle of balise telegram and RBC telegram, and then with these protocols, encoding and decoding were completed; simulationg data was recorded on real by the date record module; The recorded date can be analysed by performance analysis module, and the result be stored. Finally, co-simulation was processed based on the data of Zhenzhou-Xian high-speed railway. Tests such as multi-train movement, fault setting and temporary speed limitation setting were carried out, which verified the correctness of the CTCS3onboard co-simulation subsystem in the coupling simulation system.
