In order to solve the vibration of large-scale industrial equipment,fast wavelet transform is proposed to analyze non-stationary vibration signal and ETX+FPGA system is designed to it.The sampled input signal is wavelet analyzed on high-speed flow calculations of FPGA and embedded computer realizes data acquisition,processing,control value and human-computer interaction and other functions.Detection processing of typical non-stationary vibration signal of vibration table is realized in the laboratory enviro...
