Scrolling real-time fault diagnosis system including the hardware part and software part two

(1) hardware parts: the main resonance demodulation technique [3-4], and digital signal processing circuit design analog circuit. Impact signal generated by the failure to make the hardware resonator resonance, through the resonance of the resonator response to the weak impact signal modulation to the high-frequency resonance signals, and then the demodulation approach to the high-frequency signal processing, and then get a removed low-frequency vibration resonance demodulation of the interference wave, so as to achieve the purpose of accurate diagnosis. The final signal by the A / D converter, and then sent to DSP FFT. 

(2) software parts: recognition and diagnosis of the failure characteristics of the DSP-based vibration signal after the resonance demodulation. DSP AD to send to the digital signal, frequency conversion, the vibration signal frequency spectrum, the system can automatically analyze the spectrum obtained fault location, fault type, severity, and other conclusions and LCD display.
