With the gradual development of missile vehicles and other equipment,the requirements for data acquisition equipment on the bomb are getting higher and higher,and the data transmission should be faster and more efficient,this design adopts the FPGA and Gigabit Ethernet data transmission method,and adds a data retransmission mechanism in the process of data transmission,which accelerates the speed of data transmission,improves the efficiency of transmission,and reduces data loss and error code phenomena that can easily occur in the process of data transmission over long distances.It also reduces data loss and error code phenomena that can easily occur during long-distance data transmission.The test is verified on the FPGA board of Xilinx company,and the result proves that the data transmission of FPGA+Gigabit Ethernet is feasible,and the data transmission rate is faster,with good maintainability and stability,and can be applied in actual engineering.
