面向互联互通的铁路信号安全协议的应用

Application of railway signal security protocol for interconnection and interoperability

随着城市轨道交通日趋规模化,中国城市轨道交通以经济、资源共享及可持续发展为目标,逐步开展现代化城市轨道交通信号系统的建设和发展。在此基础上,中国城市轨道交通协会发布的《城市轨道交通基于通信的列车运行控制系统(CBTC)互联互通系统规范》,对设备间接口给出了统一规定,其中包含安全设备间的安全通信协议。面向互联互通的铁路信号安全协议旨在打通不同信号厂家的设备间的通信壁垒,从而实现城市交通网络化、共享化运营。基于互联互通的系统要求,文章将解析此系统方案对安全通信协议的影响,并对相应问题的解决方案进行深入阐述。

With the increasing scale of urban rail transit,China's urban rail transit is gradually carrying out the construction and development of modern urban rail transit signal systems with the goals of economy,resource sharing,and sustainable development.On this basis,the China Urban Rail Transit Association has released the“Specification for Communication based Communication Based Train Control(CBTC)System of Urban Rail Transit”,which provides unified regulations for equipment interfaces,including safety communication protocols between safety equipment.The railway signal security protocol for interconnectivity aims to solve communication barriers between devices from different signal manufacturers,thereby achieving networked and shared urban transportation operations.Based on the requirements of interconnected systems,this article will analyze the impact of this system solution on secure communication protocols and provide in-depth explanations of corresponding solutions to the problems.
