The Research Base On The N.N And Info-fuse Test Methods In The Analog Circuit

The fault diagnosis of the analog circuits is an advanced synthesis intercrossed subject, which is an application technology absorbing the new theory, technology and method in other subjects and fields. In the past 30 years, it has developed a great deal of theory and approaches. But the approaches are limited to deal with fault diagnosis because of the variety and complexity of the analog circuits, especially the large-scale analog circuits with the tolerance or the soft fault. Along with development of electronic technology, it brings up new challenge to fault diagnosis of the analog circuits, and requires the new theory and approaches for fault diagnosis of the analog circuits.This text on the foundation of the dictionary method of the traditional large-scale electric circuit, adopt an information to blend a technique, put forward a kind of according to the integration nerve network of the various emulation break down the diagnosis method. In order to increase definite diagnosis of the Neural Networks, advance a new theory based on integration Neural Networks consultation.This theory can deal with distinct of the fault diagnosis quickly and efficacious,and have merits of speedly,extendly.strongly robust and diagnosis online. And make the nerve network have a stronger expansion ability, it pass to increase a sub- network to reflect the breakdown phenomenon of the different type signal, thus ability the more overall reflection fault a circumstance.This text emphasized to introduce the principle of the integrated nerve network, the integration nerve network and information blend of relation, the integration nerve network sets up the mold method, the sub- network set sets up the principle and the integration nerve network to carry out strategy. finally imitates through a example to really explain the integrated nerve network function that blends according to the information, imitating a true result to express, the applied integration nerve network's carrying on the fault that imitates electric circuit to examine a patient a method is to slice actually viable.
