摘要
轨道交通基于通信的列车控制CBTC(Communication Based Train Control)正推行使用LTE-M(基于城市轨道交通的长期演进)技术规范。对CBTC采用1.8 GHz的LTE-M专网传输的通信系统建立故障树模型,提出双网交叉连接的方案,并且根据部件单一故障的特殊场景对系统的可靠性进行分析,为LTE-M用于轨道交通列车控制提供了优化建议。
Rail transit communication based train control CBTC(Communication Based Train Control) system is developing LTE-M(long-term evolution base on metro) specification.In this paper,a fault tree model is established for CBTC using communication system of 1.8 GHz LTE-M,and cross connection scheme are proposed.The faults of various components are analyzed,which provide an optimization proposal for LTE-M applying in rail transit train control.
