摘要
以既有GSM-R宏基站设备的架构特征和功能为研究对象,从RAMS分析和现网工程测试来论证既有基站设备可以通过关键模块冗余的完善来提升单套基站设备的可靠性、可用性和可维护性,从而降低在网基站退服发生的概率,减少GSM-R基站单个模块故障对包括CTCS-3在内的铁路业务的影响,降低对沿线基站设备模块故障维修时效性要求,为GSM-R宏基站继续在网长期稳定运行奠定基础,为铁路安全稳定运行提供支撑.
Abstract
This paper takes the architecture features and functions of GSM-R Macro Site equipment in the existing network as the research object,and demonstrates,through RAMS analysis and engineering tests on the operating network,that the reliability,availability and maintainability of a single set of Base Transceiver Station(BTS)currently in use can be improved by enhancing the redundancy of key modules,so as to reduce the probability of the failures and out-of-service of base stations in the network.Reducing the impact of single-module failures of GSM-R base stations on railway services including CTCS-3,and lowering the maintenance timeliness requirements for BTS module failures along the line,both lay the foundation for the continuous,long-term and stable operation of GSM-R Macro Sites in the network,and provide a solid base for safe and stable railway operation.
