铁路毫米波差异化接入ICT融合信息传输平台的研究

Research on Railway MillimeterWave Differential Access ICT Converged Information Transmission Platform

为了解决传统铁路信息系统功能单一,各平台间难以交互的问题,基于ICT融合思想提出了应用于铁路信息差异化传输平台的四层架构。首先对每层架构进行了设计与分析;再对各层功能进行了详细阐述;最后对平台实现的关键点车地大容量通信的可行性开展了测试。研究与测试结果表明该平台架构设计是合理可行的,能实现列车多场景多方式的差异化无线传输、智慧调度、实时通信、可靠传输等功能。

In order to solve the problem that the traditional railway information system has a single function and is difficult to interact with each other,based on the idea of ICT integration,a four-layer architecture of the platform applied to the differential transmission of railway information is proposed.First,the architecture of each layer is designed and analyzed;then the functions of each layer are described in detail;finally,the feasibility of the key point vehicle-ground high-capacity communication implemented by the platform is tested.The research and test results show that the platform architecture design is reasonable and feasible,and it can realize the functions of differentiated wireless transmission,intelligent scheduling,real-time communication,and reliable transmission of trains in multiple scenarios and multiple modes.
