基于LTE-M的互联互通全自动运行系统车地安全通信方案研究

Research on Interoperation FAO system Vehicle-Wayside Secured Communication Scheme Based on LTE-M

摘要: 摘要阐述了互联互通FAO(全自动运行)系统车地安全通信的特点。归纳现有互联互通CBTC(基于通信的列车控制)系统中采用基于TCP(传输控制协议)的RSSPⅡ(铁路信号安全协议Ⅱ)在实际工程项目中存在的问题，提出了一种互联互通FAO系统车地安全通信解决方案。基于RSSPⅠ，通过在LTEM(城市轨道交通长期演进系统)的设备中增加祖冲之加密算法，能有效防护开放通信系统中的伪装威胁。提出的互联互通FAO系统车地通信方案可有效解决现有互联互通CBTC系统车地通信存在的问题。

Abstract: The characteristics of interoperation FAO (fully automatic operation) system vehicle-wayside secured communication are expounded. The problems existing in the actual engineering project of the existing interoperable CBTC (communication-based train control) system using RSSP-Ⅱ (railway signal safety protocol Ⅱ) based on TCP (transmission control protocol) are summarized. A solution scheme of an interoperation FAO system vehicle-wayside secured communication is proposed. Based on RSSP-Ⅰ, the ZUC algorithm is added to the equipment of LTE-M system to effectively protect open communication system from camouflage threat. The proposed interoperation FAO system can effectively solve the problems in the existing interoperable CBTC system vehicle-wayside communication.
