摘要
随着铁路信息化技术的发展和对安全要求的不断提高,各业务系统对车-地通信需求越来越迫切。总结典型业务系统的车-地通信需求和数据传输方式,分析了GSM-R小区广播特点,结合机车综合无线通信设备(CIR)线路数据换装,提出了应用小区广播的架构模型和传送方案,并进行仿真验证,为GSM-R系统开展类似特定区域范围内数据业务提供参考借鉴。
With the development of railway information technology and the continuous improvement of the safety requirements,the demand of train-wayside communication from business application systems becomes more and more urgent.The requirements of train-trackside communication and data transmission of typical application systems are summarized and the characteristics of GSM-R cell broadcast are analyzed.Combined with line data conversion of Cab Integrated Radio Communication Equipment,the architecture model and transmission scheme of GSM-R cell broadcast is proposed and verified by simulation,providing reference for data services of the GSM-R in similar special zone.
