Design of multi-channel accelerometer frequency signal acquisition system based on FPGA
This paper designs a multi-channel accelerometer frequency signal acquisition system based on field programmable gate array(FPGA),with the FPGA chip Artix7 XC7A35T as the core.The FPGA is utilized to realize high-precision,multi-channel frequency measurement functions.The collected data is transmitted to the computer for storage through the FT232H chip.The test results show that:the system can realize frequency measurement of up to 12 channels.The measurement precision can reach 0.01 μs and frequency measurement in the range of 10～100 kHz can be realized.The precision can reach 10-4 Hz with consistent measurement precision across the entire frequency range.Through comparison with the data of Keysight 53230 A high-precision frequency counter,it has been verified that the system achieves the goal of equal precision measurement.
