Safety of technological systems
Jiříček, Petr ; Pavlík, Josef (referee) ; Hammer, Miloš (advisor)
The work deals with the safety of technological systems and can be divided into two main thematic units. The attention in the first theoretic unit is paid to aspects that affect the safety of technological systems during their technical life. It describes, together with elementary norms and acts solving the products safety, the most important principles for creating and analysing the safety. It clarifies the origin of company’s risk management, part of its quality management, mentions the faults in which products can be found and also describes the failures which have the biggest effect on these faults and of course on the safety too. Attention is further paid to the reliability analysis, as the tool that helps to create the products safety in the pre-manufacturing phase and also to technical diagnostic, as the tool to keep the safety in after-manufacturing phase. The second practical unit arithmetically analyses the safety of two high-voltage transformers. For that it was used the database of real operation numerical values that were gained during diagnostic investigations on these transformers. In addition it describes mentioned diagnostics methods and gives the new procedure for analyse of transformers’ safety by criteria matrix and weighted sum approach. The main contribution of the work can be considered the checkout and the evaluation of this procedure for use in elaboration of high-voltage transformers diagnostic values for analyzing their safety.

Vibration diagnosis of machines during routine tests
Kohutek, Tomáš ; Hammer, Miloš (referee) ; Nahodil, Petr (advisor)
This master thesis deals with the vibration diagnostics of machine vibrations during unit tests in industrial company Siemens Electric Machines s.r.o Drásov. In the master thesis is elaborated a design of the diagnostic system which contains selected methods of vibration diagnostics, methology, procedure of measurement and evaluation of measured values. The part of master thesis is also a practical example of measurement on which the mentioned system is tested.

IoT systems in diagnostics
Križanová, Bronislava ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master thesis deals with the topic of Internet of Things and its use in technical diagnostic. In theoretical part, there is a description of IoT systems and its parts, history of the IoT, communication modules and cloud systems. The second part of the thesis is focused on the description of technical diagnostic, diagnostic signal, and detailed description of two methods, most appropriate for use in IoT systems and that is vibrodiagnostic and thermodiagnostic. The practical part is focused on the application of the IoT system in technical diagnostics, including the measurement of vibrations and temperature, on the description of application in cloud system and analysis of measured results in cloud system. Prior to the end the more actions in this field of IoT systems has been recommended.

Application of diagnostic methods for devices of streem-gas blok
Hübková, Ivana ; Ondroušek, Luděk (referee) ; Matoušek, Antonín (advisor)
This master´s thesis deals with problem of reliability of technical device in general a so there is explained bathtub curve, defects and malfunctions of devices and then there is a brief outline of reliability system. This thesis further briefly describes technical diagnostic and then there is performed the vibrodiagnostic measurements of selected pumps and ventilators in in heating plant Červený mlýn in Brno. Evaluation of their condition is done according to relevant standards. Further there was done a diagnostic of the steam traps through the ultrasound diagnostic. The last part of my thesis deals with the reliability of selected specific pumps in foregoing rating plant. There are showed reliability curves of selected pumps and elaboration of data from their long-term vibrations measurement.

Design of the control device for vibrographic measurement
Weiss, Lukáš ; Čožík, Ondřej (referee) ; Levek, Vladimír (advisor)
This diploma thesis deals with designing of the control device for vibrographic measurement. The device is primary used in cooperation with MERCURY Real Time Tracking System. The main task of the device is time-controlled triggering of camera system. In the first step, the summary of basic information about technical diagnostic and vibrodiagnostic is reported. The second part describes vibrodiagnostic measurements with MERCURY system. The third part describes a hardware design of the device and functional blocks and its parameters. Next part provides a simple algorithm of the device operation and a communication protocol. Last part contains measured data of the realized device and vibrographic measurement with laboratory sample.
