Vibration monitoring of the rotating machinery has great significance for the safe operation of machinery and improving equipment utilization. Adopting high speed programmable FPGA module and combined with embedded development, a FPGA-based high-speed, multi-channel, simultaneous sampling method is proposed. The control of high speed AD chip and the layout of the hardware wiring are expounded. Meanwhile, for the functional requirements of the system, the hardware and software design and debugging are carried out. The simulation and experiment results show that for the high-frequency sine wave generated from the signal generator, the host computer can display perfect waveform, i.e. The sampling design based on FPGA can achieve the requirements for multichannel, high-speed sampling, which can realize the real-time monitoring of vibration of high speed rotating machinery.
