青藏铁路GSM-R试验工程隧道覆盖技术方案的探讨

Exploration on Coverage Technology of GSM-R Trail Engineering on Qinghai-Tibet Railway

解决GSM-R弱场强区以及盲区的覆盖问题是GSM-R整个无线覆盖系统的一个重要环节,是提高GSM-R系统可靠性的重要保障。基于GSM-R铁路专用综合数字移动通信系统对隧道覆盖的技术解决方法进行探讨,针对青藏铁路试验段工程中的隧道覆盖系统中一系列技术问题给出详细的分析。

Resolve the coverage problem of GSM-R weak field strength area and blind district is an important part for theentire GSM-R radio coverage system. It is also the basilic guarantee for improving the liability of GSM-R system. The essay,based on the GSM-R system, explores the technical resolution on tunnel coverage, and analyzes the technical problemscovering the tunnel coverage system in the trail engineering of Qinghai-Tibet line in detail.
