| Abstract: | In this paper, for the practical applications of field data collection in large-scale tests, a FPGA Cyclone chip was used as the core processor. The Cyclone chip can control the A/D conversion chip AD1674 to perform data sampling control, execute software programming in the Quartus Ⅱ Platform to implement the correct workflow control of A/D conversion, and perform serial FIR filtering on the data after AD sampling in the FPGA chip. In this paper, the logical interface of FPGA/nRF2401 was also designed to transmit the data through the radio ferquency （RF） link. |
