Aiming at the requirements of sensor data acquisition,storage and transmission of detection devices in the aerospace field,by combining FPGA technology and Gigabit Ethernet interface,an efficient data acquisition system is designed,and analyzed and studied it in detail.With FPGA as the main control chip,the collected sensor signal is conditioned and converted by the AD7606 converter,and temporarily cached into the memory structure of FIFO+RAM,stored in NAND Flash after warp frame processing,and transmitted in real-time through the Gigabit Ethernet port,and the experiment data stored in Flash can be read back after the test.
