摘要
运用GSM-R无线系统的弱场覆盖理论,选取铁路隧道区段作为研究对象,通过研究隧道弱场覆盖的解决方案,结合铁路隧道区段的GSM-R系统无线覆盖技术指标,设计出相应的隧道总体方案,对隧道区段进行覆盖设计并验证方案的正确性和可行性。各项分析表明,铁路隧道区段覆盖设计满足铁路运行的通信需求及无线覆盖的可行性要求。
By using weak-field coverage theory of GSM-R wireless system,a typical section of the tunnels in railway are selected as object of study,through the tunnel weak field covers solutions,combining railway tunnel segment of GSM-R system covering the wireless technology index,designing the corresponding tunnel general scheme,making the cover design for tunnel segment and verifying the validity and feasibility of the scheme.The analysis shows that the cover design of railway tunnel segment meets the communication requirement of railway operation and the feasibility of the wireless overlay.
