基于TETRA的石家庄轨道交通无线通信调度系统的研究与实现-电子与通信工程专业论文.docxVIP

中文摘要 本文是基于陆地集群无线系统(TETRA)的庄地铁无线通信调度系统的研究与 实现。系统采用 CASSIDIAN (欧洲宇航局)先进的 TETRA 技术，建立在 EADSTETRA 系统的 Tes(TETRAeonnectivityserver)接口平台上。 本文在对国内外地铁无线通讯调度系统的相关资料分析的基础上，根据石家 庄地铁的具体情况设计并实现了石家庄地铁无线通信调度系统。本文首先研究了 网络的拓扑结构，比较了各种结构的优缺点，提出采用环状自愈的网络结构的方 案，以保证通信传输的安全和稳定性;其次为了提高系统的可靠性，系统采用核 心网络元素的冗余备份技术和安全的行车调度方案;此外，对越区切换技术进行 了研究，设计了石家庄地铁无线通信调度系统越区切换的种类和参数;最后对系 统进行了分析设计并给出了具体的实现，通过仿真测试验证了系统设计的合理性。 本文旨在为第三方开发的应用程序提供 TETRA 环境验证测试给最终用户带 来了很多好处。由于可在实际项目安装前测试各个分系统和 TETRA 业务的集成， 将大大缩短项目的执行时间，同时提高整个系统的质量 。 关键词:TETRA;地铁;无线通信;调度系统 ABSTRACT This paper is based on the land cluster wireless systems (TETRA) of the zhuang wireless communication of scheduling system research and implementation. System USES CASSIDIAN (European space agency) advanced TETRA technology, based on EADSTETRA Tes system (TETRAeonnectivityserver) interface platform. This paper in domestic and abroad subway wireless communication scheduling system based on the analysis of the relevant information, according to the specific conditions of shijiazhuang metro design and implement shijiazhuang subway wireless communication scheduling system. This paper first studied the topology of the network, compares the advantages and disadvantages of various structure, the paper proposes the ring from the network structure of the scheme, to ensure safety and stability of the transmission; Second in order to improve the reliability of the system, the system adopts core network elements of redundancy backup technology and safety of dispatching plan; In addition, switch technology strikes area research, design the shijiazhuang wireless communication scheduling system the handoff type and parameters; The last of the system analysis and design and give a specific implementation, through the simulation validation test the rationality of the design of the system. CASSIDIAN for third party development application provides TETRA environment verification testing to end users have brought many benefits. Owing to the actual project before installation
