铁路普速旅客列车智能广播系统的设计与实现

The Design and Accomplishment of the General Railway Passenger Train Intelligent Broadcasting System

笔者从分析普速旅客列车传统广播存在的问题入手,介绍了基于4G移动通信网络的计算机系统利用GPS定位、INS惯性导航、震动识别等技术感知旅客列车运行状态,利用优先级迭代算法、TTS语音转换技术、语音片段截取技术等编辑列车播音资料,从而自动按次序向旅客推送各等级广播内容,达到智能化广播的目的。

Analyzing the existing problems of traditional broadcastings quality of general railway passenger trains,the author introduces the computing system based on 4G.This system is able to perceive the train operation states by using Global Positioning System,Inertial Navigation System,vibration recognition and other technologies.Taking advantage of preferential iterative method,Text To Speech(TTS),audio segment clipping and other techniques to edit broadcasting information of the train,each grade of broadcasting content will be pushed to passengers in order automatically,in this way,the purpose of intelligent broadcasting is achieved.
