摘要/Abstract

摘要： 北京轨道交通已广泛采用LTE-M车地综合通信系统，在换乘车站存在频率干扰问题。为满足LTE-M系统安全性及可靠性要求，梳理北京轨道交通新线工程换乘车站典型站型。对LTE-M系统在换乘车站场景下进行干扰分析计算，总结干扰防护措施，降低行车安全隐患，为换乘车站LTE-M系统频率干扰防护提供借鉴。

Abstract: LTE-M vehicle-ground integrated communication system has been widely used in Beijing rail transit, and the problem of frequency interference is inevitable in transfer stations. In order to ensure the safety and reliability requirements of LTE-M system, this paper sorts out the typical type of transfer stations of Beijing Rail Transit new line project. The interference analysis and calculation of LTE-M system in the transfer station scenario are carried out, and the interference protective measures are summarized to reduce the train operation safety hazards, so as to provide reference for the frequency interference protection of LTE-M system in transfer stations.
