摘　　要：为更好了解干线铁路列控系统中信号机显示、轨道电路码、车载信号以及限速等系统指标特性和操作要点,针对CTCS-2级列控超速防护系统,结合高速列车的动力学模型和延时特性,通过对ATP模式转换关系的研究,基于车载ATP子系统设计了一种车载ATP模型,并进行仿真及测试.该文模拟列车在区间以及各种进站方式下运行的场景,生成不同的行车许可,实现ATP防护曲线的仿真,对运营场景进行复现,使其直观形象.该仿真系统不仅操作方便,而且模块化的设计思路有益于提高程序的可读性.Aiming at overspeed protection system of CTCS-2 train control,the characteristics and operation points of signal display,track circuit code,on-board signal,speed limit and other system indexes in the system are well examined,and an on-board ATP model is designed and simulated on the basis of its subsystem combined with the dynamic model and delay characteristics of high-speed train through the research on ATP mode conversion relationship.It then simulates the running scenes of trains in intervals and in various entrance modes,generates different driving permits,realizes the simulation of ATP protection curve,and reproduces the running scenes to make them visual.The modular design of the simulation system is beneficial to improving the readability of the program with convenient operation.
