摘要
通过应用于轨道基础设施检测数据车地无线传输的方法,以4G无线网络设计实现车地无线数据传输系统,系统可将车上轨道检测系统的检测数据通过互联网传回地面数据中心,人员不必跟车检测、分段拷贝数据、长时间数据编辑。回传至地面的轨道不平顺数据经过地面数据综合分析指导轨道工务系统线路维修。车地无线传输系统实现从系统采集端直接将合成数据回传至地面,无需车上安装专门的服务器,可用于搭载式轨道检测系统中,大大提高了轨道基础设施检测的效率和实时性,为铁路线路安全运营提供有效数据支持。
With the train-ground wireless transmission method of track infrastructure inspection data,and the train-ground wireless data transmission system designed and implemented with 4G wireless network,the system can transmit the inspection data of the track inspection system onboard to the ground data center via the Internet,without the necessity of any on-board inspection staff,data copying in sections and data editing for a long time.The track irregularity data transmitted back to the ground is analyzed comprehensively in combination with the ground data to guide the track maintenance of track maintenance system.The train-ground wireless transmission system can directly transmit the synthesized data back to the ground from the acquisition end of the system,without a special server installed on board,and the system can be used in the onboard track inspection system,which greatly improves the efficiency and real-time performance of track infrastructure inspection,and provides effective data support for the safe operation of railway lines.
