摘要
根据工信部要求，国家将停止对450～470MHz频段在无线列调系统的支配，全线将使用GSM－R系统替换450MHz无线列调通信系统，7万多km的既有线路450MHz无线系统面临更新改造问题。因此，提出一种相对经济可靠同时又切实可行的GSM—R系统资源冗余配置方案非常关键。结合铁路工程实例，探讨铁路冗余资源配置方案的研究，希望对未来既有线改造方案有一定的借鉴和指导意义。
According to the requirements of Ministry of Industry and Information Technology of the People＇s Republic of China, the GSM-R system will be used instead of the 450MHz wireless train dispatching system because 450-470MHz band will be forbidden to use for wireless train dispatching systems for Chinese railways. So over 70,000km of existing lines with 450MHz wireless systems will be reconstructed. It is very necessary to present a GSM-R system resources redundant configuration scheme being relatively economical, reliable and feasible. This paper takes actual railway projects as examples to discusses railway resources allocation schemes, hopefully providing some reference and guidance for the future reconstruction of existing lines.
