摘要：The fault waveform data extraction is the key of the analog circuit fault diagnosis. The paper presents a tolerance analog circuit fault waveform data extraction method. First, tolerance analog circuit simulation uses OrCAD / Pspice circuit simulation software in order to generate fault waveform data. Then, program in MATLAB automatically and accurately extract fault waveform data. Finally, the fault waveform data in binary form is stored in the matlab working space. And the bridge rectifier capacitor filter circuit fault data extraction set as an example is explained in detail, through which the effectiveness of the method is verified. This method solves the problem of data interface between the two, laying the foundation for the realization of analog circuit fault diagnosis fault.
