摘要
针对我国铁路的CTCS-3级列控系统的特点,提出了CTCS-3级列控系统无线通信网络综合监测技术,对车-地数据传输的几个关键接口——Abis接口(BSC与BTS)、A接口(MSC与TRAU)和PRI接口(MSC与列控RBC)上列控呼叫的信令流程、数据传输过程以及线路状态等进行完整的监测和记录,并采用综合分析和联合诊断技术、多层协议分析与解码技术、多用户实时跟踪与查询技术等关键技术,为列控数据传输分析、故障定位和分析、通信网络优化与维护以及干扰分析等方面提供技术依据。
This article discussed comprehensive network monitoring technical used in CTCS-3 wireless communication system based on the characteristic of CTCS-3,which enables monitoring over several key interfaces,including the Abis interface between BSC and BTS,the A interface between MSC and TRAU,and the PRI interface between MSC and RBC and can made integral recordings of the whole procedure of signaling and data transmission of train operation control calls as well as track conditions.With comprehensive analysis and joint diagnosis technology,multi-layer protocol analysis and decoding technology,multi-user real time tracing and inquiry technology,and etc.,this monitoring system can provide technical data for CTCS-3 data transmission analysis,fault location and analysis,optimization and maintenance of communication network,and interference analysis.
