一种新型列车通信系统的研究

Study on a Novel Train Communication System

以国内现有的运营列车广播线作为通信信道,采用软、硬件结构与设计,建立以数字语音压缩为基础的列车旅客报警及内部通信系统,确保系统的适应性与工作的稳定可靠性。该系统能在各种情况下,及时响应乘客及乘务人员发出的各种报警信息,以无线寻呼方式立即通知列车三乘人员(乘警、列车长、安检员)及乘务员进行处理;并能在列车任意编组时,组成列车内部通信系统,实现各乘务室相互间的拨号呼叫及话音通信。

This paper describes the design and implement of train's internal alarm and communication system based on digital voice compressing techniques by software and hardware designing methods, using the broadcast line in the civil old type train running currently as communication channel. The system has high stability and variability, can process warning signals and notice workers in the train on time, can construct an internal voice communication system for every carriage between each other at any time.
