摘要
针对多通道信号采集中存在数据量大、数据传输速度慢和外场试验中稳定性差等问题,该文设计出一种基于FPGA的以太网数据传输系统。该系统是以Xilinx K7系列FPGA为主控芯片,使用亚德诺公司AD7606芯片对信号进行采集,设计AXI_MASTER模块进行接口转换,使用镁光公司DDR3 SDRAM作为数据缓存芯片,最终设计以太网UDP协议将数据打包传输至上位机端。该系统经过测试表明,能够有效地进行信号的采集、快速地读写数据和稳定地传输。该系统应用比较广泛,性能比较稳定且具有一定的参考价值。
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 FPGA.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 reference value.
