Risks in technical diagnostics
Machů, Roman ; Hammer, Miloš (referee) ; Hájková, Alena (advisor)
This bachelor thesis deals with the issue of risks in technical diagnostics. The theoretical part of the thesis is divided into two parts. In the first part attention is paid to technical diagnostics in general and its methods. The second part then summarises the risk issues in general, including examples of different risk assessment techniques. Tables containing examples of the risks associated with selected methods of technical diagnostics, i.e. vibrodiagnostics, tribodiagnostics, electrodiagnostics and thermodiagnostics, have subsequently been produced. These risks have been assessed and mitigation measures have been proposed for significant risks.

On-line diagnostic monitoring systems for vibration of machines
Cirhanová, Iva ; Prostredník, Daniel (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with diagnostic monitoring systems of machine vibration. First of all, a technical diagnosis with a focus on diagnostic methods, means and diagnostic systems is generally described. Special attention is paid to vibrodiagnostics and termodi-agnostics. In the next part of the thesis there are on-line diagnostic monitoring systems, their parameters and their use in technical practice. Emphasis is placed on systems from SKF, ADASH and ifm electronic. The systems are compared and the economic aspect is briefly outlined. In the bachelor thesis is also evaluated.

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.

Temperature Measurement in Technical Diagnostics
Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.

Study of fatigue life of roller bearings type 6204 -2Z
Poláček, Vojtěch ; Svoboda, Petr (referee) ; Klapka, Milan (advisor)
This bachelor thesis deals with the basic description of produced by fatigue failure of ball bearings. In the paper there is a description of basic diagnostic methods of machine parts. Following there is a study of vibration, their recording and the evaluation concerning bearing lifetime. The aim of the experimental part of the paper is to check the functionality and suitability od the VDT2000 analyzer and VDT Control Center software, both made by company VidiTech, s.r.o. together with the SA67 laboratory experimental stations owned by the Department of Design at Faculty of Mechanical Engineering, which were used for examining the 6204-2Z bearings. The aim of the lifespan exam is to confirm the reliability of the bearing failure warning by the analyzer and to assess the ability to record the first stages of bearing damage.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.

Modern approaches in the maintenance field
Pšenková, Tereza ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This master thesis deals with position of the maintenance in the company structure and with modern management approaches. One of the highest levels of maintenance is the proactive maintenance, which is using the technical diagnostics to find out the causes of failures. The most inportant in case of machines are vibrodiagnostics and thermodiagnostics, which are going to be applied on the motors in company Bosch Diesel s.r.o.
