列车在复杂、特殊区段高速运行时,会导致频繁的移动通信越区切换,严重影响列控通信业务的安全。为保证通信的持续性和可靠性,需要对GSM-R系统方案进行合理规划。结合合蚌客运专线设计实践,通过对并线区段、泄洪区段、枢纽区段等复杂、特殊区段进行理论研究和现场收集实测数据,得出在蚌埠站设同址双套基站,站型按照C2+1和C1+1方式配置;在窑河泄洪区段设置共站址双网冗余方案;在枢纽区段,增加基站等方案。
When a train runs in a complicated and special section at a high speed, frequent mobile communication handovers will be caused, which seriously affects the safety of train control services. In order to ensure the continuity and reliability of communication, the GSM-R system plan needs to be reasonably planned. Combining with the design practice of the combined mussels passenger line, through theoretical research and field collection of complex and special sections such as parallel section, flood discharge section and hub section, it is concluded that there are two sets of base stations with the same site in Bengbu Station, Type configuration in accordance with C2 + 1 and C1 + 1; in the kiln flood discharge section set up a total site redundancy dual network solutions; in the hub section, increase the base station and other programs.
