Design of Data Acquisition and Transmission System Based on Ethernet
In response to the problems of large data volume,slow data transmission speed,and poor stability in field experiments in multi-channel signal acquisition,this paper designs an Ethernet data transmission system based on FP-GA.The system is based on Xilinx K7 series FPGA as the main control chip,and uses AD7606 chip from Adeno Company to collect signals,and designs AXI_MASTER module performs interface conversion,using the DDR3 SDRAM from Magnolia Corporation as the data cache chip,and ultimately designs an Ethernet UDP protocol to package and transmit data to the upper computer.This system has been tested and shown to be effective in signal acquisition,fast data reading and writing,and stable transmission.This system is widely used,with stable performance and certain ref-erence value.
