既有铁路GSM-R系统改造方案的探讨

Transformation of Existing Railways GSM-R System Scheme

我国近8万公里的既有铁路450MHz模拟无线列调拟逐步改造为GSM-R系统。目前既有铁路由于征地、供电、投资等各种因素的限制,建设标准难以与高铁一致。基于既有线的业务应用和特征,结合实际工程,提出一种适合既有线GSM-R系统改造的优化方案,给即将到来的大规模既有线改造提供参考。

In China,450 MHz train dispatch analogue radio of nearly 80,000 km existing railway lines would be transformed into GSM-R system.At present,the construction standard of existing railway cannot be consistent with that of high-speed railway due to land acquisition,power supply,investment and other limits.In view of service application and the characteristic of existing railway and in combination with actual project,an optimal solution for improving the GSM-R system of existing railway is proposed,offering reference for upcoming large-scale transformation of existing railways.
