摘要
总结了国内外CBTC（基于通信的列车控制）系统车地通信系统的工作方式和频段情况,分析了目前工作在免许可频段的CBTC系统在使用中所面临的问题。城市轨道交通站台的2.4GHz免许可频段电磁环境复杂,对CBTC系统抗干扰能力提出了较高要求。在分析了CBTC系统业务需求和频段特性基础上,针对工作在免许可频段的CBTC系统提出了配置和使用建议。
The working schemes and frequency status of CBTC train-wayside communication system in oversea countries and China are summarized, the current issues of CBTC working in permission free frequency band are ana- lyzed. Since the complex permission free 2.4 GHz EMC situation in rail transit station area raised higher require- ments to CBTC anti-interference capability, with an analy- sis of CBTC requirements to radio and the features of fre- quency band, some suggestions about the configuration and usage of CBTC working in permission free frequency are put forward.
