【摘要】 随着我国客运专线的大规模修建,GSM-R无线网络通信系统作为我国铁路专用通信的发展方向,已经逐渐成取代现在有铁路无线通信系统。特别是在武广、郑西高速客运专线中,GSM-R系统成为CTCS-3列控系统中地面设备与车载设备进行数据交互的主要信息通道,是实现高速列车实现铁路通信信号一体化不可或缺的重要组成部分。因此,对于GSM-R网络的可靠性和安全性提出了更为严格的要求。在此研究背景下,论文主要探讨了GSM-R网络优化的技术方案,并针对沪昆线GSM-R专用移动通信网络建设的实际情况,对GSM-R网络的建设和优化进行了技术方案设计。论文对GSM-R系统的频段划分、业务模型、无线传播模型等进行分析,详细阐述了其中关键技术指标的内容和规范要求,并指出了网络优化的重要性。对影响GSM-R无线网络服务质量的因素进行了全面的分析,并针对这些因素设计了网络优化流程方案。根据以往的GSM-R网络建设和施工经验,论文设计了包括干扰消除、电磁环境测试以及系统业务带宽建设等在内的GSM-R系统网络建设方案。针对长昆客运专线GSM-R网络的应用需求,从GSM-R网络覆盖、干扰、切换等方面对网络优化方案进行讨论,设计其正线和联络线的无线网络建设方案。从网络的上下行干扰、网络覆盖、网络运用质量测试、客专开通后期调整优化等问题上进行研究并提出解决方案,为以后的GSM-R网络建设优化工作提供了可借鉴的宝贵经验和设计思路。更多还原

【Abstract】 With the large-scale construction of the Passenger Dedicated Line, GSM-R as the development direction of China’s railway communication wireless network communication system has been gradually to replace the existing railway wireless communication system. Especially in the Wuhan-Guangzhou, Zhengzhou-Xi’an high-speed Passenger Dedicated Line, the GSM-R system is the data information interacting channel of ground equipment and vehicle equipment for CTCS-3train control system, it is an important part of high-speed trains to achieve the integration of Railway Signal&Communication integration. Therefore, there are more stringent requirements for the reliability and security of the GSM-R network.In the background of this study, the paper mainly discusses the GSM-R network optimization technology, and aim at Shanghai-Kunming dedicated mobile communication line of GSM-R network construction the actual situation, construction and optimization of the GSM-R network. By analyzing the allocation of frequency bands of the GSM-R system, business model, and wireless propagation model, Elaborated on the contents of the key technical indicators and regulatory requirements, and pointed out the importance of network optimization. The paper conducted a comprehensive analysis of the factors affecting the GSM-R wireless network quality of service, and network optimization process is designed for these factors. According to the GSM-R network construction and construction experience, the paper designs building program which includes interference cancellation, the electromagnetic environmental testing and system bandwidth business and other GSM-R system network.According to Chang-Kunming Passenger Dedicated Line GSM-R network application requirements, via discussing the aspect of GSM-R network coverage, interference, switching etc., the paper designs the main line and contact line wireless network-building program and construction and optimization of the GSM-R network. It is the valuable experience and design ideas for the construction of GSM-R network optimization in the future.更多还原
