摘要
我国铁路特别是在西部地区,处于高山峻岭之中,为保证铁路通信的安全,解决列车司机与地面人员在山区特别是在长大隧道及隧道群中的语音及数据通信,首先要解决好无线列调系统在山区的场强覆盖问题。文章探讨并比较了山区的3种无线列调系统的覆盖方案;同时对漏泄同轴电缆的覆盖范围及监控进行了探讨,以资在实际工程中,设计人员根据实际情况和工程投资进行优选利用,同时也希望能对山区无线列调设计提供一定的依据。
The railways in our country, especially those built in the west regions, are laid among high mountainous, To ensure a safe communication for railway traffic, and keep a smooth voice and data communication between engine drivers and dispatchers in the mountainous areas, especially in long tunnel or tunnel groups, the priority should be given to high-field covering of radio dispatching system in those regions. This paper compares three kinds of scheme for covering radio dispatching system in mountainous areas, and at the same time carries out a discussion of covering areas and monitoring function of leakage coaxial cable. The research results are expected to be reference for designers as well as basis for design of radio dispatching system in mountainous areas.
