5G与高速铁路信号系统结合应用探讨

Combined Application of 5G and High-Speed Railway Signal System

目前高速铁路信号系统通过线缆实现室内系统与室外轨旁设备的传输与控制,存在站场改造时间短、工作量极大,安全风险高与系统软件功能试验量大等的问题。利用5G技术极大的传输速率,极小的时延,极高系统容量和大规模设备连接的应用特点,信号系统通过无线传输向分散式控制方向转变,主要体现在室内系统设备与室外轨旁信号设备控制实现5G无线通信控制;室内轨道电路低频码信息与室外轨道电路设备之间通过5G实现无线传递;安全数据网组网取消传统的光纤组网而采用通过5G无线组网;通过高速铁路沿线的5G无线组网实现邻车通信,进一步实现列车的安全监督控制。

At present,the signal system of high-speed railway realizes the transmission and control of indoor system and outdor trackside equipment through cables,there are some problems,such as short transformation time,great workload,high safety risk and large anount of system sofware function test.Utilizing the application characteristics of 5G technology,such as maximum transmission rate,minimal delay,extremely high system capacity and large-scale device connection,the signal system will be transformed to decentalized cootmol through wireless transmission.It is mainly rllected in:indoor control system and outdoor trackside equipment are both to be contolled by wireless ommumication through 5G;indoor track circuit low-frequency code information and outdoor track eircuit equipment to be transmitted by wireless communication through 5G;the traditional optical fiber network for security data network will be replaced by 5G wireless network;the neighborhood communication is realiaed through the 5G wireless network along the high-speed railway line,and the safety superision and control of the train will be further realized.
