| | Summary: |
| | This study performed a theoretical-experimental procedure for monitoring and analysis of the intersection allocation in the middle of the line girder in the vertical plane using a laser sensor VL6180X. The applied measuring system is a non-destructive method, a new, easy-to-apply case of monitoring static and dynamic parameters in the structures of constructive systems based on the treated physical model. Registering test results is a single format of an electrical continuous digital signal collected in the Arduino programming environment in the time domain with simultaneous exporting to the widely used MS Excel format. Measurement results prepared for the fast Fourier transform using a self-made software model in the Matlab2021a environment. Therefore, software modelling using DFT and iDFT verified the relevant data in the temporal and frequency domain. Finally, DFT analysis showed slight deviations in vertical displacement of the girder system treated in this study compared to the results of the FFT-treated analysis of the identical displacement signal in the vertical plane. |
