Data processing from the online diagnostic system
Cirhanová, Iva ; Jankových, Róbert (referee) ; Zuth, Daniel (advisor)
This master thesis deals with data processing from an online diagnostic system. The theoretical part of the work is divided into three chapters, the first deals with technical diagnostics as such, there are basic terminology and concepts associated with technical diagnostics, such as diagnostic methods, tools, models and signals. The second part is focused on diagnostic systems and their division. This chapter also provides some examples of online diagnostic monitoring systems from three different companies. The last chapter of the theoretical part is devoted to the description of the possibilities of data collection from diagnostic systems, ie. description of communication buses and protocols. The practical part of this work focuses on creating an application for data collection and visualization.

Design of operational limits for machine tool diagnostic system
Hrbáček, Vlastimil ; Zuth, Daniel (referee) ; Jankových, Róbert (advisor)
The Master's thesis deals with online vibration diagnostics of a milling center. It contains a methodology to determine the vibration operating limits and to detect machine of condition monitoring. The thesis also contains a general description of maintenance and technical diagnostics with a focus on vibrodiagnostics. The main part of the thesis is to solve the problem of determining the operating limits of spindle vibration depending on the production program. The essence of the solution is to determine vibration limits for individual milling tools.

Visualization and online control of important parameters of block and tap-changing transformers at the Dukovany nuclear power plant
Holeš, David ; Mareček, Oto (referee) ; Mastný, Petr (advisor)
The thesis focuses on a design of visualization and setting limits of important parametres of power and own-consumption transformers at the nuclear power plant Dukovany. In the first part there is a description of a present technical state of oil power transformers at this power plant, including a description of a currently installed transformers monitoring system and electro monitoring system. The second part deals with a design of a visialization of parametrs and a diagram design of active-access displays of monitored parametrs of these transformers. In the thesis there is also a description of web interface with a new visualization. The last part of the thesis contains a design of setting the limits and criteria of important monitoring parametres of these transformers.
