铁路通信漏缆实时监测系统的应用及实现研究

漏泄电缆的性能对铁路GSM-R移动通信网络的安全运行有很重要的影响。目前在铁路运营期间,受多种因素的限制,对漏泄电缆的维护非常困难。通过深入分析、研究漏缆实时监测系统,明确系统的架构及监测原理,引申出精确定位的概念。并以山西中南部铁路通道工程为依托,针对不同隧道类型提出相应的设计方案,且通过工程实践加以验证,为铁路通信工程的漏缆监测系统提供设计参考。

Research on the Application and Realization of Real-time Monitoring System for Railway Communication of Leaky Coaxial Cable

The performance of leaky coaxial cable plays an important role in the safe operation of railway GSM-R mobile communication network. During the railway operation,the maintenance of leaky coaxial cable is currently very difficult due to a variety of factors. The system architecture and monitoring principle are identified and the concept of precise positioning is derived based on careful analysis and research on the real-time monitoring system of leakage cable. With reference to Shanxi centra-south railway project,the corresponding design schemes are proposed in accordance with different tunnel types and verified by engineering practices,which may provide references to the design of leakage cable monitoring system in railway communication engineering.
