Research and development of radio-magnetotelluric signal acquisition instrument based on ZYNQ processor
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.
