铁路通信传输的构成及实现方法

随着目前我国的铁路列车向高速化方向的迈进,为了保证有效的人机控制和提高运输效率,就必须要求我们建立健全功能完善的,技术构成先进的铁路通信网,本文就通过对相邻线、既有线通信设备和线路条件的分析,结合铁路通信传输系统的设置,以通信业务的需求的角度出发,从通信业务的需求、主要通信系统和容量的选择、电话交换系统、通信调度系统、无线通信系统、站间行车电话及其他专用通信系统、应急通信系统等方面,全面的阐述铁路通信传输系统的构成和实现的方法。

With the running speed of the train in our country become higher and higher, a fully functional railway communication network with advanced technology must be built to ensure the effectiveness of man-machine control and enhance the transport efficiency. Based on the analysis of adjacent line, existing power line communication equipment and line conditions, for the purpose of the communicate efficiently, the constitution and implement method of the railway communication system will be full-scale discussed from the need of communication, the capacity of the main system, the telephone switching system, the dispatch communication system, the wireless communication system, the blocking telephone and other private communication systems and the emergency communication system.
