Research and Implementation of CTCS3 Onboard Co-Simulation Subsystem

为构建高速铁路耦合大系统,提供列车运行控制信息,设计了CTCS3级列控车载协同仿真子系统。通过设计与高速列车动力学、牵引传动、自动驾驶、高速铁路系统基础数据库等各子系统间的接口,结合列车速度防护算法,完成了列控车载协同仿真子系统对高速列车运行的信号控制。该系统实现了列车运行控制系统与高速列车系统动力学仿真系统以及牵引传动仿真系统的协同仿真。以郑西客运专线数据为基础,进行协同仿真,并在仿真过程中进行追踪运行、故障设置和临时限速设置测试,验证了在耦合大系统下的列控车载协同仿真子系统的正确性。

To build a coupled large-scale system of high-speed railway so as to provide train operation control information, the CTCS3 onboard co-simulation subsystem was designed in this paper. And then, the interfaces of this subsystem with every other subsystem were designed, such as with the subsystems of high-speed train dynamics, traction drive, automatic train operation, underlying database of high-speed railway and so on. Further on, in combination with automatic train protection algorithm, the signal control over the operation of high-speed railway by using this train control onboard co-simulation subsystem has been achieved. This subsystem can achieve the co-simulation among train operation control system, high-speed train dynamics simulation system, and traction drive simulation system. Finally, based on the data of Zhengzhou-Xi＇an passenger-dedicated line, a co-simulation was carried out, companied with operation tracing, and with relevant tests by setting the fault and setting the temporary speed restriction, which have verified the correctness of this train control onboard co-simulation subsystem under a coupled large-scale system.
