摘要
针对超宽带探地雷达在道路下方路基缺陷和管道布局检测中的重要性,设计了一种基于ZYNQ-7000全可编程SOC芯片的超宽带探地雷达控制系统。在SOC芯片FPGA部分设计了基于AXI4总线的控制电路,芯片ARM CPU部分移植了Linux操作系统并运行超宽带探地雷达软件控制程序,通过以太网将雷达数据发送至服务器端进行显示和存储。通过超宽带探地雷达对地面的测试,每一列共100个像素点,为一次等效采样所获取的数据,行像素每两个之间测量轮编码器输出4次脉冲信号,表示探地雷达移动2 mm距离。表明超宽带探地雷达控制系统能够很好的控制超宽带探地雷达,并传输所获得的雷达数据。
Because of the importance of ultra-wideband ground penetrating radar in the detection of subgrade defects and pipeline layout under the road,an ultra-wideband ground penetrating radar control system based on ZYNQ-7000 fully programmable SOC chip is designed.In the FPGA part of the SOC chip,the control circuit based on AXI4 bus is designed.The ARM CPU part of the chip is transplanted with the Linux operating system and runs the ultra-wideband ground penetrating radar software control program.The radar data is sent to the server for display and storage via Ethernet.Through the test of the ground by the ultra-wideband ground penetrating radar,each column has a total of 100 pixels,which is the data obtained by one equivalent sampling.The measurement of the round encoder between the two pixels of the line pixel outputs 4 pulse signals,indicating the ground penetrating radar moving 2 mm.It shows that the UWB ground penetrating radar control system can control the UWB ground penetrating radar well and transmit the obtained radar data.
