铁路隧道平调信号覆盖技术的研究与应用

Study and Application on Flat Shunting Signal Covering Technique in Railway Tunnel

本文主要针对铁路运输作业过程中，调车系统在铁路隧道内存在通讯信号盲区的难题，提出启用一个新的异频双工工作频点专门用于水域隧道的平面调车．在隧道内的洞壁上架设泄漏电缆，用于隧道内的信号发射与接收。经过实施，证明该技术不仅解决了铁路隧道内存在通讯信号盲区的难题，而且还缩短了铁路运输作业时间，节约了一定的货车延时费用。

Aiming at the difficult problem that there are bhnd areas of communication signal in shunt- ing system in tunnel during railway transportation operation process, it is put forward that a new working frequency of diplexer is specially used for flat shunting control in Shuicheng tunnel. A leaky cable set up in wall of the tunnel is used to emit and receive signal. The application of the technique demonstrates that this technique not only overcomes the problem of bhnd areas of communication signal in railway tunnel but also shortens the time of railway transportation operation and reduces delay cost of van.
