THE ALGORITHM OF DIAGNOSTICS MEDICAL EQUIPMENT ON THE BASIS VALET TRANSFORMATIONS

Abstract

This paper considers the problem of vibro-acoustic diagnostics of the technical equipment of the hospital. The development and application of methods and means of diagnostics allows to increase the efficiency of the use of technology in the processing of the received data. An important part of diagnosis is the study and analysis of the diagnostic signal. In time, the survey allows to identify damages and needs assessment equipment. The development and application of methods and means of diagnostics allows to increase the efficiency of its use. An important part of diagnosis is the study and analysis of the diagnostic signal.

Analyze this signal using the wavelet transforms that translate the signal from a time representation in time-frequency. There is specialized software for mathematical calculations (Mathcad, MatLab, Mathematica), which implemented the wavelet transform of signals. But because of its limitations in the calculations and the difficulties of implementing complex algorithms, there is a question about creating a simple to implement algorithm for diagnosis of signal processing using wavelet analysis. Methods of analysis of audio data using wavelet functions are able to transcend and complement the traditional approaches in the field of digital audio processing and diagnostic equipment. In comparison with the Fourier transform, corduroy allows for a more flexible and large-scale analysis, which leads to the exact separation properties of the signals, the graphical and numeric representation of the obtained coefficients.

Developed on the basis of wavelet-transformation algorithm provides a more accurate and qualitative assessment of technical condition of equipment, compared with traditional techniques, and also characterized by a special sensitivity in the initial stages of damage.

 Key words: Wavelet transform, diagnostics-medical equipment, evaluation of technical condition of equipment.
