| description | In order to meet the real-time and high-precision multi-channel acquisition requirements of a large rotating machinery equipment in the monitoring process, this paper proposes a design scheme of multi-channel vibration signal acquisition and detection system based on FPGA. The system adopts the master/slave FPGA architecture and realizes the 128-channel parallel real-time data acquisition function with a sampling frequency of 100 kHz in the strong noise environment. Then, by designing a random resonance signal detection system with adjustable parameters, the signal-to-noise ratio of the signal is improved and the accuracy of the system detection in the rotating environment is enhanced. The test shows that the system has good real-time performance, stability and effectiveness. |
