隨著鐵路的現(xiàn)代化、高速化,通信信號技術(shù)的融合和一體化是必然的趨勢。GSM-R具有適應(yīng)鐵路運(yùn)輸特點(diǎn)的優(yōu)勢,及更符合通信信號一體化技術(shù)發(fā)展的需要,GSM-R屬于專用移動通信,專用于鐵路的運(yùn)營管理,是有效的調(diào)度指揮通信工具。
本論文主要對GSM-R系統(tǒng)、CTCS-3(China Train Control System-3)列控系統(tǒng)進(jìn)行了初步介紹,詳細(xì)論述了列控傳送系統(tǒng)的工作原理以及列車控制信息通過GSM-R系統(tǒng)在機(jī)車與無線閉塞中心間的傳送過程。最后對當(dāng)前GSM-R在CTCS-3列控中的運(yùn)用情況、可行性以及與基于軌道電路的列控系統(tǒng)相比具有的優(yōu)勢進(jìn)行了簡單的分析。

Abstract
With the modernization of the railway, high speed, communication signal technology integration and integration is an inevitable trend. GSM-R has the characteristics to adapt to the advantages of rail transport, and more in line with the development of communication signals the need for integration of technology, GSM-R is in a private mobile communications, dedicated to railway operation and management, command scheduling is an effective communication tool.
This thesis focuses on GSM-R system,CTCS-3 train control system was initially introduced in detail the train control system works well sending train control information through the GSM-R system in the locomotive and the wireless transmission process between occlusion Center Finally, simple analysis feasibility and track circuit based train control system has advantages compared the current GSM-R in the CTCS-3.
