| Abstract: | A data acquisition system based on field programmable gate array(FPGA) is designed.The system has four acquisition channels.It is configured by commands of host computer,and can choose real-time sampling or high-speed sampling according to actual needs.Hardware circuit of the acquisition system is designed.FPGA program is developed to implement functions such as data acquisition,data storage,automatic electric bridge balance,and status feedback.FPGA communicates with the host computer via RS-232 serial port.The test shows that the expected functions are implemented,and the system can achieve 2.88 kHz in real-time sampling and 91.5 kHz in high-speed sampling. |
