TCC系统与CTC系统的接口仿真研究

Study on Interface Simulation Between TCC and CTC

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。

As a safety-criteria computer system, high-speed railway TCC（ train control center） system has an in- terface with the CTC（ centralized traffic control） system that is nonsafety-eriteria computer system, which can af- fect 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 ex- plained. The experimental result shows that it is convenient and feasible to adopt serial interface only for infor- mation exchange. And if the hardware interface adopts the cross-connect redundant configuration and the soft- ware design uses query communication, it can achieve better communication effect.
