摘要
铁路综合数字移动通信系统(GSM-R)因具有成熟、稳定、安全可靠等优势,在当前高速铁路通信网络中得到广泛应用。CRH380A型动车组由于其运行速度快,在GSM-R网络中容易发生无线接收故障。GSM-R无线接收故障多为无线超时,高铁动车组因未能及时收到基站子系统(BSS)传来的信息而报错。无线超时一般由车载电台故障、无线信道质量下降等原因引起。通过对GSM-R网络中CRH380A型高速动车组无线接收案例进行分析,为GSM-R网络的进一步优化覆盖及无线故障排查提供参考。
Railway integrated digital mobile communication system(GSM-R) has been widely used in high-speed railway communication network because of its advantages of maturity,stability,safety and reliability.Because of its fast running speed,CRH380A EMU is prone to wireless receiving failure in GSM-R network.The wireless receiving faults of GSM-R are mostly due to wireless timeout,and the high-speed rail EMUs reports errors because it fails to receive the information from the base station subsystem(BSS) in time.Wireless timeout is usually caused by vehicle radio failure,wireless channel quality decline and other reasons.The analysis of network of GSM-R CRH380A type high speed EMU wireless receiving case will provide reference for further optimization of GSM-R network coverage and wireless troubleshooting.
