中文摘要:
      提出一种基于全球定位系统(GPS)同步时钟信号的野外无人地球物理探测采集分布式系统,使用Cyclone V EP5CEBA4F17C和ARM Exynos 4412 等为硬件的节点探测仪器设计方案。该节点设备利用现场可编程门阵列(FPGA)作为主控器,FPGA将接收来自ADS1282采集到的数据与本地GPS芯片采集到的时间戳进行数据合并,ARM嵌入式系统对合并后数据进行实时分析与存储,在PC端对各节点设备数据进行汇总并根据时间戳对齐,最终得到同步后的分布式地球物理3D图像数据。用该设备进行测试,结果表明该测试系统初步实现了远距离、大范围地球物理同步节点的数据采集。
英文摘要:
      This paper presents a global positioning system (GPS) unmanned geophysical acquisition distributed systems. Use Cyclone V EP5CEBA4F17C and ARM Exynos 4412 as the hardware node detection equipment design. The device utilizes field gate array (FPGA) as a master. FPGA receives data from the ADS1282 merge data collected with the local GPS chip collected timestamps. ARM embedded system for real time analysis combined data and storage. On PC terminal,aggregating data for each device and aligned according to the time stamp. Finally get synchronized distributed geophysical data of 3D image. Testing with the device showed that the system initially realized the long distance, large scale geophysical data acquisition synchronization.
