TCC系统与CTC系统的接口仿真研究

高速铁路列控中心(TCC,train control center system)子系统作为安全系统，其与非安全系统调度集中(CTC,centralized traffic control)系统的接口是影响高速铁路安全高效运营的关键接口。结合TCC系统的特点和CTC系统对通道的要求，对该接口进行软、硬件仿真，给出了报文交换过程，并对接口通信故障处理进行了说明。实验结果表明，对这种安全系统与非安全系统的接口，因其仅进行信息交互，采用串行接口是方便可行的。同时，硬件上采用交叉连接冗余配置，保证可靠连接；软件上采用查询方式通信，可以实现较好的接口通信效果。

Study on Interface Simulation Between TCC and CTC

As a safety-criteria computer system,high-speed railway TCC(train control center)system has an interface with the CTC(centralized traffic control)system that is nonsafety-criteria computer system,which can affect the safe and efficient operation of the high-speed railway.According to the characteristics of high-speed railway TCC and the communication channel standard of CTC,this kind of interface is simulated in hardware and software,while its message-exchange process is presented,and its communication fault processing is explained.The experimental result shows that it is convenient and feasible to adopt serial interface only for information exchange.And if the hardware interface adopts the cross-connect redundant configuration and the software design uses query communication,it can achieve better communication effect.
