郑西高铁GSM-R基站传输电路误码分析

Analysis of Transmission Circuit Error of GSM-R Base Station in Zhengzhou-Xi'an High-speed Railway

CTCS-3级列控系统是动车组列车的主要行车设备,GSM-R(铁路综合数字移动通信系统)为CTCS-3级列控系统进行车-地数据交互提供重要网络通道。以郑西高铁发生的1次CTCS-3级无线连接超时故障为例,分析了GSM-R基站电路传输误码对CTCS-3级列控系统数据传输的影响,并针对基站存在的安全隐患提出了解决方案。

CTCS-3 train control system is the main driving device of Electric Multiple Unit trains while GSM-R provides an important network channel for data interchange between the on-board part and wayside part of the CTCS-3 train control system. Taking CTCS-3 wireless connection timeout fault occurring in Zhengzhou-Xi＇an high-speed railway as example,the influence of circuit error of GSM-R base station on data transmission of CTCS-3 system is analyzed and a solution is put forward to deal with safety hazards in base station.
