摘要
CTCS-3级是基于无线传输信息并采用轨道电路等方式检查列车占用的列车运行控制系统;它主要面向提速干线、高速新线或特殊线路,基于无线通信的固定闭塞或虚拟自动闭塞。因此,GSM-R的质量如何将直接关系到CTCS-3列控系统的正常运行,并将影响到目前中国铁路大量投入建设运行的客专高速铁路的行车秩序。下面从几个方面来简单阐述GSM-R在CTCS-3系统的作用、GSM-R故障分析以及如何通过对GSM-R各接口信令的监测分析来判断定位CTCS-3系统的故障。
CTCS-3 system is designed based on wireless information transmission and train occupancy detection by track circuits. Based on wireless communication platform, the system can realize fi xed block or virtual automatic block and it is mainly used for speeding-up lines, new high-speed lines and specifi c lines. Therefore, the quality of GSM-R is closely related to the normal operation of CTCS-3 system and the operation order of a number of high-speed dedicated passenger lines which have been put into service or under construction in China. The paper sets forth the role of GSM-R in CTCS-3 system and the fault analysis of GSM-R, as well as the way to identify and locate system faults in CTCS-3 system by monitoring and analyzing the GSM-R interface signaling.
