Abstract
研发基于ZYNQ处理器的ARM嵌入式天然场射频大地电磁法信号采集系统.该系统集成了采集控制模块、数据读取模块和数据滤波模块,采用FPGA高速逻辑门电路、FIR滤波器以及ARM嵌入式系统等技术手段,实现RMT信号的采集、传输、滤波和存储.仿真和对比试验结果表明:该系统性能稳定,滤波模块阻带衰减大于70 dB,系统采集的数据反演结果精准,能提供高精度地质信息,所设计的信号采集系统能够为国产化射频大地电磁法勘探设备研发提供一种技术方案.
A signal acquisition system for natural field RMT(radio-magnetotelluric method)based on the ZYNQ·processor and ARM embedded technology was developed.The system integrates acquisition control modules,data reading modules and data filtering modules,and FPGA high-speed logic gate circuits,FIR filters and ARM embedded systems were adopted to realize signal acquisition,transmission,filtering and storage for RMT.The simulation and experimental results show that the system has stable performance with all filter module stopband attenuation greater than 70 dB.The inversion results of the data collected by the system are accurate and can provide high-precision geological information.The designed signal acquisition system provides a technical solution for the development of domestically produced RMT exploration equipment.
