【摘要】 改革开放以来,我国铁路事业取得了非常大的发展。安全是铁路运输事业的生命线,是运输生产永恒的主题。特别是近年来,铁路通信事业也在如火如荼的进行之中,如何保障铁路通信事业稳定而又安全的发挥作用,无线环境的监测正在成为一个非常重要的课题。GSM-R(GSM for Railway)系统是专门为铁路通信而量身打造的系统,它是基于当今世界上运营最成熟的GSM移动通信系统而打造的,在GSM系统的标准上加上了适合铁路高速移动环境使用的标准。我国相关部门已经为铁路通信划分了专门的频段,这足以显示出国家对铁路运输事业的重视,保证铁路事业稳定而又安全的进行对国民经济是至关重要的。2006年,青藏铁路上的GSM-R移动通信系统建成,这是全亚洲第一个GSM-R移动通信系统,从那以后,越来越多的GSM-R系统开始被建设起来。如何保障GSM-R系统稳定而又安全地工作,越来越被国家和人民重视,也成为一个非常重要的课题。本论文首先对GSM-R移动通信系统的系统结构和发展现状进行了概括,从外部和内部两个方面总结了 GSM-R系统中存在的各种干扰以及干扰产生的原因,然后介绍了 GSM-R无线环境的通信质量参数并且分析了获得这些参数所采用的测量方法,接着对国家无线电监测中心出台的《GSM-R电磁环境保护技术方案》进行了仔细的研读和分析,结合对无线环境测量方法的研究设计了 GSM-R无线环境监测系统。监测系统包括控制中心子系统,监测点子系统,网络传输子系统三个部分。其中控制中心子系统进一步划分为智能管理次子系统、人机交互界面次子系统和数据库次子系统三大部分,监测点子系统进一步划分为智能管理次子系统、电磁环境监测次子系统、人机交互界面次子系统和数据库次子系统四大部分。在论文中对监测系统的基本功能和系统结构的设计工作进行了分析,重点分析了数据库模块的设计与优化。更多还原

【Abstract】 China’s railway industry has made tremendous development since the reform and opening up.Safety is the lifeline of the railway transportation.In recent years,the railway communication industry is also developing quickly.To ensure the stability and security of railway communications,monitoring of railway communications wireless communication environment is becoming more and more important.GSM-R mobile communication system is specialized for railway communications.It is based on the world’s most mature and widely used GSM system.It adds some other function to suit for high-speed mobile environment.The relevant department has set up a special band for railway communications to ensure the safety of railway transport.Since GSM-R mobile communication system is finished on the Qinghai-Tibet Railway,more and more GSM-R communication systems are under construction.The security of railway transport draws more and more attention of the country and the people,and it has also become a very important issue.This paper firstly makes an introduction of GSM-R communication system including its background,system architeche and development.Then we know what the GSM-R is and what the GSM-R is built for.Secondly the paper summarizes all kinds of interfaces including the external interface and the internal interface,which affect the normal work of the system.Thirdly the paper introduces some communication quality parameters and designs the methods we can take to mearsue them.Forthly the paper makes an introduction of Technology Solution to GSM-R Monitoring System which is formulated by the State Radio Monitoring Center.After the introduction and research on GSM-R system,we design the GSM-R wireless environmental monitoring system which is based on the methods of mearsuing the communication quality parameters.The monitoring system consists of three parts.They are control center subsystem,monitoring point subsystem and network transmission subsystem.The paper introduces the struct and function of the monitoring system briefly,and then analyzes the design and optimization of the database module detailly.更多还原
