ICT infrastructure is installed, and data are automatically transferred via WIFI protocol to
the central database. They are processed and reported on a daily basis.
During the experiment the mobile phone (smartphone) was additionally installed on the window of the machine (see Fig. 3) and using freeware application the vibration data have been
acquired and stored to *.csv file. The first assumption was to measure vibration with the highest
available sampling frequency. Finally, the data have been pre-processed (down-sampled) to 1 Hz
sampling frequency as in onboard monitoring system to easily synchronize all data together.
