基于闭环监测链的GSM-R网络无线连接超时分析

Wireless Connection Timeout Analysis of GSM-R Network Based on Closed-loop Monitoring Chain

对于基于GSM-R无线通信网络传输信息的CTCS-3级列车运行控制系统,无线连接超时会对行车效率产生影响。在GSM-R网络相关接口闭环监测的基础上,对几种典型的无线连接超时故障进行分析,总结出无线连接超时分析流程,以供信号人员分析高铁通信故障时参考。

For CTCS-3 train control system with GSM-R wireless communication network for data transmission, once the wireless connection timeout of the CTCS-3 train operation control system occur, the efficiency of train operation will be affected. Based on closed-loop monitoring of GSM-R network-related interfaces, typical wireless timeout failures are analyzed and the analysis process of wireless connection timeout is also summarized, providing reference for signal personnel in failure analysis of high-speed railway communication.
