Návrh embedded systému pro aplikaci akcelerometrů v technické diagnostice

Abstract

This thesis focuses on the design and implementation of an embedded bearing diagnostics system using MEMS accelerometers. The system is designed based on the Raspberry Pi 5 platform and is compatible with a variety of MEMS accelerometers, which are carefully selected with respect to their practical applications. Using a specially designed graphical interface, the user can configure measurements, view the vibration time history and perform signal analysis including envelope and spectrum calculations. The application also includes the calculation of frequencies typical of bearing damage based on the bearing geometry, or an auto-detection function can be used to detect defects by finding the largest envelope amplitude and finding its corresponding harmonic multiples. The measurement results are clearly displayed directly in the GUI. The whole solution is designed as a low-cost, flexible and easily extensible alternative to professional diagnostic tools and is suitable for laboratory use, educational purposes or further development.
