我国铁路GSM-R的发展研究

目前,世界上已有21个国家计划建设GSM-R铁路线,我国初步建设了代表高原、重载和繁忙干线的青藏、大秦和胶济线三条GSM-R铁路线。通过这三条试验线的建设,我国在GSM-R理论研究、应用技术和设备研发等方面积累了一定经验,形成了我国基于GSM-R的完整铁路应用体系。随着GSM-R的发展,我国将在互联互通、终端技术、无线网络测试、电磁环境监视、干扰协调以及构建虚拟专用网实现铁路增值业务等关键技术上开展深入研究。

Research on Development of GSM-R in China Railway

China has already constructed three GSM-R railway lines,i.e. Qinghai-Tibet Railway,Datong-Qinhuangdao Railway,and Jinan-Qingdao Railway,respectively representing plateau,heavy haul,and busy truck lines. Based on these lines,an integrated GSM-R railway application system has been set up in China. With the development of GSM-R,deep research on key techniques will be continued,such as interconnect and interworking,terminal technique,wireless network test,electromagnet environment monitor,interference coordination,and building up virtual special network to provide railway value-added service.
