1、GSM-R在国内外铁路通信中的应用吴杰13281144摘要:GSM-R是一个全新的铁路无线通信系统,在欧洲铁路得到了较好的应用,也将为实现我国铁路跨越式发展的总体目标发挥重要作用。近10年来,我国铁路经历了重载运输、电气化改造、既有线提速等一系列的技术进步,推动了铁路通信的发展。随着通信的发展,铁路运营里程也在不断扩大,预计到2020年,全国铁路运营里程将达到10万千米左右。在这样庞大的铁路交通运输网中,要想大幅度提高铁路复线率、电气化率、自动闭塞比重,实现了主要繁忙干线客货分线运输,必须选择一种新的铁路数字移动通信技术。本文通过对新型铁路无线通信系统GSM-R的阐述,旨在
2、分析当前GSM-R的状况,根据目前国家批准的4MHz贷款频率资源,结合我国铁路运输对通信的实际应用需求,研究探讨GSM-R系统中功能寻址的功能,为我国铁路GSM-R系统的合理应用提出一些参考意见。abstract:GSM-Rtechniqueisbasedonthemature,generalpublicmobilewirelesscommunicationsystemonGSMplatform,specificallytomeettheapplicationanddevelopmentofdigitalrailwaymobilewirelesscommunicationt
