摘　　要：随着列控系统的发展和5G通信技术的普及,CTCS-3级列控系统和新型列控系统无线闭塞中心的车地通信网络由GSM-R/GPRS向5G-R方向发展。为应对车地通信网络升级带来的工程技术挑战,提高列控系统对不同车地无线通信网络模式的兼容性,分析电路域与分组域车地无线通信网络模型和数据传输协议的差异项,以及在电路域和分组域模式下常见的RBC-ATP通信场景的交互流程;提出一种兼容GSM-R电路域和GPRS/5G-R分组域多模网络的RBC多模车地通信接口实现方案,描述了多模车地无线通信接口的系统边界及软硬件设计关键技术的原理和具体实现。通过仿真试验,验证了RBC多模车地无线通信接口功能的正确性和有效性。该方案有助于CTCS-3级列控系统/新型列控系统RBC的车地通信向5G-R升级的工程实现,为后续车地通信升级提供技术支撑和实践参考。With the evolution of train control systems and the popularization of 5G communication technology,the train-ground communication network for wireless block center of CTCS-3 train control system and the new-type train control system has been evolving from GSM-R/GPRS to 5G-R.To cope with the engineering technical challenges brought by the upgrade of train-ground communication networks and to enhance the compatibility of train control systems for different wireless transmission modes,this article analyzes the discrepancies of train-ground wireless communication network models and data transmission protocols between the circuit switched transmission mode and packet switched transmission mode,and describes the interaction process of common RBC-ATP communication scenarios in circuit switched transmission mode and packet switched transmission mode.A scheme is proposed for implementing RBC multi-mode train-ground communication interface compatible with GSM-R circuit switched transmission and GPRS/5G-R packet switched transmission,which gives a detailed description of multi-mode train-ground communication interface,including the system boundaries,the principles and implementations of key technologies for its software and hardware design.The correctness and effectiveness of the functions of RBC's multi-mode train-ground wireless communication interface have been verified through simulation test.The scheme will contribute to the engineering implementation of upgrading the CTCS-3 train control system/new-type train control system RBC's train-ground communication to 5G-R,providing technical support and practical reference for subsequent upgrades of train-ground communication.
