摘　　要：ITCS系统是当今较先进的无线列车控制系统之一,已经成功地运用到我国的青藏铁路.本文分析了ITCS系统功能及车载控制设备的结构;讨论了ITCS系统车载控制单元的可靠性,基于故障树对系统可靠性评估的一般步骤;依照本系统的典型配置和实际工作过程,定义系统的故障模式;并根据故障模式和可靠性预测建立了系统的故障树;在此基础上,根据马尔可夫过程的特性,对与门、或门进行计算推导,实现了整个系统的可靠性定量计算;最后结合项目实施,对故障状态下的应急策略进行了详细分析.ITCS, which has been successfully applied in China Qinghai-Tibet railway, is one of the modern advanced wireless train control system. In this paper, the system function and structure of on-board control device are introduced. Based on the general procedures of FTA for reliability assessment, with the typical configuration and practical operation process, the fault mode of ITCS are defined and the fault tree is built accordingly, then based on the features of Markov process, the reliability derivation of and gate and or gate are realized for the quantitative calculation of the entire system. Finally, combined with the project implementation, the emergency response poli- cies under certain fault state are detailed analyzed.
