摘要
新一代高铁列车列控系统智能化要求,使车地通信数据较之前更为丰富多样,数据传输的安全可靠性要求更高,延时要求更低。原有的基于GSM的列控通信系统已经不能满足新需求,需要研发新的基于5G技术的新一代列控通信系统。对5G-R通信系统进行研究,设计新的基于嵌入式系统的车载电台,提出地面网络系统的结构、组成和接口。详细分析业务数据在整个车地传输过程所经历的协议封装/解封和接口传递过程,阐述新一代列控通信系统在满足未来车地通信要求的适应性,为高铁列控智能化奠定通信基础。
The requirements for intelligent train control systems of the new generation of high-speed railways make the train-ground communication data richer and more diverse than before,and there are requirements for safer and more reliable data transmission and for lower delays.The original train control communication system based on GSM cannot meet the new requirements,so it is necessary to develop a new generation of train control communication system based on 5G technology.In this paper,a 5G-R communication system is studied,a new onboard radio based on embedded system is designed,and the structure,composition and interface of ground network system are proposed.The protocol encapsulation/de-encapsulation and the interface transmission process of service data in the whole train-ground transmission process are analyzed in detail,and the adaptability of the new generation of train control communication system to meet the requirements of future train-ground communication is expounded,which lays a communication foundation for intelligent train control for high-speed railways.
