柴欣电子与通信工程高铁GSM-R 系统电磁环境测试及干扰分析应用研究The Applied Research of High-Speed Railway Electromagnetic Environment of GSM-R System Test and Interference Analysis随着我国高速铁路建设的持续发展，现有的铁路运行通信系统和控制系统 已经不能满足高速铁路运行的需求，目前高速铁路的设计时速和运行时速都超 过200km/h。我国引入比较成熟的GSM for Railways 系统作为我国高速铁路专 用的通信系统，为了避免电磁干扰对系统的网络通信造成影响，保障铁路通信 系统的畅通，电磁环境测试尤其必要，它是为解决潜在的和未知的信号对高速 铁路通信系统的干扰而进行的一项工作。 本文以包西待建铁路建设中的电磁环境测试为核心，介绍了GSM-R 系统 的基本构成、用频分配、建站选址等情况，分析了潜在的内部干扰和未知的外 部干扰，给出了电磁环境测试的必备的测试仪器、依据标准和基本的测试流程 和数据分析步骤。 最后完成了GSM-R 系统电磁环境的测试方法和干扰分析方法，有针对性 的设计并实现了整套全自动测试系统。通过在包西、西宝等高速铁路的电磁环 境测试中对该系统的实际应用，验证了电磁环境自动测试系统的设计实现，对 提高GSM-R 系统电磁环境测试及干扰分析的时效性和准确性具有显著效果。 本论文的研究成果对于快速、准确、可靠的完成高速铁路GSM-R 电磁环境测 试及干扰分析具有重要的实际价值，对于实现在复杂电磁环境下其它用频台站 的测试具有较强的参考价值。37柴欣the communication sthe communication s；干扰分析；自动测试分析软件；the communication sthe communication sc environment test，Interference analysis，the韩子硕信号与信息处理1580924781334王建望建筑与土木工程1533914653

In recent years, with the rapid development of automobile industry, positioning and navigation, wireless communications technology, and needs of the current socio-economic development, promoted intelligent transportation systems came into being. ITS combines wireless communications, positioning and navigation, control, geographic information systems and computer processing techniques used to effectively integrate the entire transportation management system, effectively alleviate traffic congestion, improve road capacity, reduce accidents, reduce energy consumption, reduce environmental pollution. As an important part of intelligent transportation systems, GPS vehicle location monitoring system research has important practical significance. This paper analyzes the current situation of GPS vehicle location system at home and abroad as well as through in-depth research on key technologies related to GPS, GIS, 3G communications technology, and proposed the use of 3G communications technology to build GPS vehicle location system, and overall design. The GPS vehicle location system is divided into two parts that vehicle monitoring center system and vehicle positioning communication system. This paper focuses on the GPS monitoring center monitoring and management platform and server communication middleware. GPS monitoring and management platform is developed C # in the Microsoft Visual Studio 2010 development environment .NET and JS languages. Module of GIS location service is called map data and secondary development interface of Mapbar, achieved vehicle location and tracking on a Web electronic map. Middleware of server communication is communication the vehicle terminal and GPS monitoring management platform for bridge, to complete mainly the information exchange between them. Server middleware package for vehicle information of new and unified, using the provisions of the agreement, so that they can communicate more smoothly. Finally, proposed and implemented a communications server IOCP optimization model, it is a good solution to the problem of server load, effectively improve the bearing capacity of the server in the Socket communication programming basis. GPS vehicle location system is integration of GPS, GIS, 3G communication technology, database technology and computer data processing technology, improved the real-time location, information transmission, monitoring and management of vehicles stability and reliability, and successful realization of the intended target. After testing, system performance is stability. Currently, the system has been successfully applied in business and government dispatch vehicles, logistics, rental and other industries.
