摘　　要：为解决既有时速250 km的高速铁路提至更高速度时通信各子系统面临的技术改造问题,对通信各子系统的速度适应性以及提速改造方案进行研究。从技术标准层面,对通信各子系统与列车速度的关系进行分析。结合既有信号列控等级和GSM-R的覆盖方式,提出GSM-R系统的提速改造方案,并对传输系统、综合视频监控系统及电源设备的提速改造方案进行研究,可供类似工程借鉴参考。In order to solve the problem of technical transformation of various communication subsystems when existing high-speed railways at 250 km/h are upgraded to a higher speed level,this paper studies the speed adaptability of various communication subsystems and the retrofitting scheme for railway speed-up.Firstly,from the perspective of technical standards,it analyzes the relationship between various communication subsystems and train speeds.Secondly,considering both the existing train control level of signaling system and the coverage mode of GSM-R,it proposes the retrofitting scheme for railway speed-up of GSM-R system,and studies the retrofitting schemes for railway speedup of transmission system,integrated video surveillance system and power equipment,which can be used as references for similar projects.
