摘要
分析城市轨道交通车地无线通信技术的应用现状,根据目前不断增长的无线带宽需求,将TD-LTE(time division-long term evolution,时分长期演进)技术作为最合适的车地无线通信方案。以郑州市轨道交通1号线为现实背景,利用轨道交通地下空间的真实环境,经过严密的分析研究,将合理的区间无线覆盖方案与先进的TD-LTE技术完美结合,实现城市轨道交通车地无线的流畅传输。
This paper analyzes the current application status of train-ground wireless communication technology in urban rail transit. The TD- LTE （time-division-long-term evolution） technology was chosen to be the most appropriate solution for the ever-increasing requirement of wireless band. With the application of TD - LTE technology in the project of Zhengzhou subway Line 1, it is analyzed and studied rigorously how to combine the section wireless coverage method with the advanced TD - LTE technology in underground space. Fluent transmission between train and land of urban railway transit was reali- zed.
