摘要
随着我国高速铁路和客运专线的快速建设,应用GSM-R网络的铁路并线区段越来越多,由于中国铁路GSM-R只有4 MHz频率资源,因此如何在保证并线区段无线覆盖的前提下有效地运用有限的频率资源并避免网内干扰是GSM-R网络规划的重点。分析铁路并线的类型,并对郑武客运专线与合武铁路并线区段、盘营客运专线与哈大客运专线联络区段两个典型铁路并线区段的GSM-R覆盖方案进行了研究。
With construction of high-speed railways and passenger dedicated lines in our country,GSM-R network is applied to more and more lines with parallel sections.So it is very important to ensure the radio coverage of these sections and avoid interference within the network under the premise of effective use of limited frequency resources in GSM-R network planning.This paper analyzes types of parallel sections of lines,and studies the GSM-R radio coverage scheme of two typical parallel sections of the lines,such as the section of Zhengzhou-Wuhan DPL and Hefei-Wuhan railway and the section of Panjin-Yinkou DPL and Haerbin-Dalian DPL.
