The Analysis of Mechanical Fault Signals Based on MATLAB and VC

This paper describes a mechanical-signal analysis system, based on Visual C + +6.0, calling MATLAB engine. This system makes Fourier analysis and wavelet analysis to time domain signa. Simultaneously, this system makes fault diagnosis based BP neural network. VC communicates with ACCESS database through ADO. The feature signals generated by the process of time domain, frequency domain analysis, sample datas, test datas and diagnostic results are stored in the database. Therefore, through combining the three to play their respective advantages., greatly reduces the software development cycle, so that the code has been simplified to improve the efficiency of the system.
