客运信息交互系统无线通信协议研究

Research on wireless communication protocol of Interactive System for railway passenger transport information

本文基于铁路客运信息无线交互系统,讨论无线通信环境下数据通信的网络协议和应用协议的设计。铁路客运信息无线交换系统基于中国移动的GPRS通道,实现列车和地面车站系统进行动态通信。对网络协议选择和传输控制流程进行探讨。

This article was based on Wireless Interactive System for railway passenger transport information, discussed the wireless communication environment, network protocol and application protocol. With characteristics of a complex network conditions and the geography, Wireless Interactive System for railway passenger transport information was based on China Mobile＇s GPRS channels, achieved dynamic and real-time communication between ground-station and mobile terminal on train. In this paper, the network protocol selection and transmission control processes were discussed.
