Application Analysis of Analog Neural Network VLSI & Pulse Stream Technique on Fault Diagnosis

A analog neural network VLSI & pulse stream technique is presented. The technology can realize the hardware circuit of neural network model recognition and classify the fault samples directly. It makes original analog noise signal including fault information go through the signal processing and neural network computation. Then the voltage value of output capacitor in VLSI circuit is obtained, which represents Euclid distance between template fault signal and the signal needed to be recognized. By above methods, the real time & online hardware recognition of noise fault signals is realized.
