摘　　要：动车组车地无线传输受限于移动网络带宽限制,数据传输间隔较长,无法准确反映车载系统运行状态,提出了一种基于压缩感知的车地传输数据压缩算法,能够在地面高精度地还原车载原始数据的同时,大幅压缩车地传输数据量,提高了车地带宽利用率,为动车组运行监测和故障应急指挥提供了更详实的数据支撑。The train ground wireless transmission of EMU is limited by the bandwidth of mobile network,and the data transmission interval is long,which cannot accurately reflect the operation state of on-board system.A train ground transmission data compression algorithm based on compressed sensing is proposed,which can greatly compress the amount of train ground transmission data while approximately accurately restoring the original on-board data on the ground,and improve the utilization rate of train width,it provides more detailed data support for EMU Operation Monitoring and fault emergency command.
