摘要
在高速铁路ATO系统中,ATO车载设备与TSRS设备利用GPRS分组交换网络进行车地通信。对ATO车载无线传输技术进行深入研究,重点研究其中几项关键技术的解决方案:无线会话管理、无线通信协议、ATP接口适配、GPRS电台接口适配,介绍相关无线传输软件的设计和实现,并对该软件在京沈客专试验期间的延时指标进行分析。
The 0nboard-ground communication in ATO system of HSR is realized via GPRS packet switched network by using ATO onboard equipment and TSRS equipment. Deep studies are made in this paper on ATO onboard wireless transmission technology and solutions on several key issues are highlighted including wireless dialogue management, wireless communication protocol, ATP interface adaptation, GPRS radio interface adaptation. The paper also introduces the design and application of wireless transmission software and analyzes the delay parameters of the software during its trail operation on Beijing-Shenyang PDL.
