FPGA has been widely used in data acquisition and processing in modern industrial production and scientific research due to its integration of VLSI and programmable devices. In this paper, a multi-channel data acquisition system based on FPGA is designed to meet the requirements of data acquisition in aircraft power supply inspection. The designed system realizes the conversion from FPGA local bus to PCI bus through PCI9054 bridge chip, and then completes the connection and communication between the data acquisition system and the upper motherboard through PCI bus. The system debugging results show that the designed system can realize the data acquisition and processing function.
