Reviewer: doc. Ing. Jakub Arm, Ph.D.
The aim of this thesis is the conceptual design, software implementation, and experimental validation of a system for the automated collection, processing, and annotation of vibration data from a SIPLUS CMS card designed for continuous monitoring of machine condition. The database architecture consists of storing periodic characteristic values and raw vibration records in an InfluxDB database using Python service. Their metadata and annotations are stored in a PostgreSQL relational database. The thesis includes a literature review in the areas of diagnostics, data preprocessing, and methods of vibration signal analysis. The proposed data annotation methodology enables the preparation of training datasets for machine learning algorithms designed for fault detection and predictive maintenance of equipment within the Industry 4.0 framework. The results of the work include a functional system for data collection and visualization in the Grafana environment and a service for advanced analysis of measured data.

Process of defence
Student odprezentoval svou práci a zodpověděl otázky oponenta. Komise měla dotaz na užitou aplikaci výsledné práce a na cíl zadané práce. Student zodpověděl důvod užití dvou databází InfluxDB a PostgreSQL. Komise poukázala na nedostatečnou automatizaci provedení sběru a zpracování dat. Student zodpověděl metody použité analýzy a způsob zpracování a vyhodnocení. Způsob vyhodnocení je v práci rozpracován však poněkud sporadicky.
