摘要
在阐述铁路移动通信技术演进路线,分析既有列控系统仅依靠车地双向通信,不足以彻底保障列车运行安全的基础上,研究LTE-R D2D技术与列车运行控制系统结合应用和关键技术。结果表明,将D2D技术应用于列控系统,可有效提高列车运行安全与作业效率。
Basing on the technology evolution of railway wireless communication, this paper describes the insufficient of train control system that is inadequate to prevent the trains form collision. When we are combining device-to-device communication of LTE-R with train control system, the train operation safety and efficiency is improved. Key technologies of the new application are described in the paper.
