摘　　要：高速铁路长大隧道需要按照GSM-R冗余组网方案进行覆盖。目前GSM-R网络可采用数字直放站与分布式基站作为数字中继设备,两种设备均有多种组网方案。从故障应对能力、载频利用率、建设成本等多个角度开展分析,对比多种高速铁路隧道内GSM-R数字中继设备冗余组网方案,提出各种方案的适用范围和性能优劣。Long tunnels of high-speed railway need to be covered according to GSM-R redundancy networking scheme.At present,GSM-R network can use two kinds of digital relay equipment:digital repeater and distributed base station.Both of the equipment have a variety of networking solutions.This paper analyzes the fault response capability,carrier frequency utilization,construction cost and other aspects,compares various GSM-R digital relay equipment redundancy networking schemes in high-speed railway tunnels,and proposes the application scope and performance advantages and disadvantages of various schemes.
