摘　　要：在特种设备试验过程中,需要对试验数据进行采集与存储,针对试验过程中数据传输速率不高以及传输可靠性的问题,设计了一种FPGA与千兆以太网结合的数据传输系统,采用UDP协议提高数据传输速率的同时加入数据重传机制以及包计数以提高数据传输的可靠性。此外,选用卷积码的编码方式实现数据的校验与纠错,进一步提高数据传输的速率与可靠性。在Xilinx公司(已被AMD收购)的FPGA板卡上进行验证,实验结果证明FPGA+千兆以太网的数据传输是可行的,且有效提高了数据传输速率,具有良好的可维护性和稳定性,能够在实际工程中应用。During the testing of special equipment,issues arise concerning the low data transmission rate and the transmission reliability,therefore,the test data collection and storage are required.To address this problem,a data transmission system combining FPGA and Gigabit Ethernet is designed,using UDP protocol to increase the data transmission rate while adding data retransmission mechanism and packet counting to improve the reliability of data transmission.The experiment is verified on Xilinx's(acquired by AMD)FPGA board.The experimental results prove that FPGA+Gigabit Ethernet data transmission is feasible and effectively improves the data transmission rate.Additionally,it exhibits favorable maintainability and stability,making it suitable for practical engineering applications.
