High-speed Microcontroller Based System to Real-time Analyzing the Mechanical Waves in Structures
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2017, Vol 24, Issue 1
Abstract
Nowadays high-speed microcontrollers are employed to accomplish many applications in different domains, due to their flexible characteristics and structures. In this paper, the microcontroller algorithm per-forms a fast time-frequency analysis by discrete Fourier transform (DFT) on variable time portions of the vibration signal. System can be easily customized so that a spectrum with variable range and density is achieved. Also, the real-time microcontroller based system (R-TMBS) has been thought as a stand-alone system as well as to be included in a more complex system, which can function in closed-loop when the system feedback is obtained via R-TMBS.
