列车运行控制系统的目的是保证列车安全可靠和高效率运行。传统的列车运行控制系统是以车站联锁设备为核心,由车站联锁设备检查从调度中心发出的控制命令是否正确,然后选路,最终由司机确认地面信号,发出行车命令。但随着列车速度的提高,极易造成对地面信号的误认,而且基于轨道电路的信息传输已不能满足高速列车对安全性的要求,而基于通信的无线传输列车运行控制系统则能满足。无线闭塞中心系统RBC是基于通信的列车运行控制系统的地面核心部分。介绍了郑西客运专线RBC系统,分析了系统的应用背景和特点。详细叙述了系统的功能、结构组成,并且对接口部分从内部和外部两方面进行了介绍。
The purpose of train operation control system is to ensure safe and reliable train operation and high efficiency. The traditional train operation control system is based on the station interlocking equipment as the core. The station interlocking equipment checks whether the control commands issued from the dispatch center are correct and then selects the road. Finally, the driver confirms the ground signals and issues a driving order. However, with the increase of train speed, it is very easy to misidentify terrestrial signals, and the information transmission based on track circuit can no longer meet the requirements of high-speed train for safety. The train-based operation control system of wireless transmission based on communication can meet the requirement. Wireless Blocking Center System RBC is a ground-based part of a train-based train control system. The RBC system of Zhengzhou-Xi’an Passenger Dedicated Line is introduced, and the background and characteristics of the system are analyzed. Described in detail the function of the system, the composition of the structure, and the interface part of the internal and external aspects were introduced.
