Digital Processing System for Shallow Surface Frequency-domain Electromagnetic Detection Based on FPGA+DSP
摘要
Abstract
To meet the requirements of acquisition,transport and spot efficient processing of the re-ceived signal in shallow surface frequency-domain electromagnetic detection,a digital processing system for shallow surface frequency-domain electromagnetic detection based on FPGA+DSP was proposed.Data ac-quisition,control,and transmission FIFO module were compiled in FPGA.New universal parallel port UPP was used to achieve high data transfer.Efficient data processing algorithm was written with orthogo-nal lock-in amplification method based on TMS320C6748.The system was controlled and the results were displayed with PC software through the RJ45 network port.Test results have shown that the digital pro-cessing system of the proposed architecture for different metals has a strong ability of discovery.Data transmission rate is accelerated,system working time is shortened and work efficiency is improved.关键词
