既有铁路视频补强及铁路5G-R改造配套设施方案研究

Enhancement Plan for Video Monitoring System and Upgrade Scheme for Railway 5G-R and Supporting Facilities of Existing Railways

根据中国国家铁路集团有限公司相关要求,为保障铁路运输安全,满足现代化通信系统发展需求,需对既有铁路进行视频监控系统补强,对既有专用移动通信系统进行5G-R升级改造。二者改造时间存在重叠,且在改造过程中,除自身系统外,均涉及承载网、光缆、电源以及机房等配套设施的完善与升级。结合目前中国国家铁路集团有限公司对视频监控系统补强以及5G-R系统的技术要求,在速度200~350km/h、C3及非C3列控等级等不同维度的典型线路条件下,研究二者自身的改造方案及各自配套设施改造需求;通过对比分析,识别二者改造过程中的共性与差异,提出共同改造时的配套设施改造方案。研究成果可供今后类似改造工程借鉴参考。

In accordance with the requirements set by China State Railway Group Co.,Ltd.,it is essential to enhance the video monitoring system of the existing railways and upgrade the current private mobile communication system to 5G-R,thus,to ensure the safety of railway transportation while accommodating the evolution of modern communication systems.The upgrade schemes for both systems are somewhat aligned,and during the upgrade process,enhancements and upgrade will also be made to supporting facilities,including the bearer network,optical cables,power supplies,and equipment rooms.Upgrade plans are developed for both systems in line with China State Railway Group Co.,Ltd.’s technical requirements,taking into account various typical line conditions,such as operational speeds of 200-350 km/h and C3 and non-C3 train control levels.Through comparative analysis,the similarities and differences in the upgrade processes for the two systems were identified,leading to the proposal of a coordinated upgrade scheme for the supporting facilities.The findings of this study can serve as a reference for future similar upgrade projects.
