Functional safety of pressure transmitters of BD SENSORS company
Šimoník, Martin ; Hlinka,, Jiří (referee) ; Fuchs,, Pavel (advisor)
This master thesis examines the functional safety of the pressure sensor XMP i which is produced by BD SENSORS Company. The aim of this thesis is the demonstration of compliance of the pressure sensor XMP I with functional safety integrity level SIL3 requirements. The thesis is divided into three parts. The first part deals with the concept of functional safety, defines the basic concepts of functional safety, compares the approaches of functional safety according to selected standards and provides a general procedure for the functional safety determination. The second part deal with technical systems reliability defines reliability indicators and describes selected types of reliability analysis used in practice, especially the FMEA/FMECA analysis. Third part deals with the reliability analysis of the sensor XMP i and with evaluation of results.

Use of a safety PLC for gas burners
Petr, Vojtěch ; Žlebek, Roman (referee) ; Polsterová, Helena (advisor)
The topic of this diploma thesis is the safety of a gas burner control. The aim is to fully automate the system by using a gas burner safety control system (Fail-Safe PLC) so as to reduce to minimum the risks. Because great emphasis is placed on safety, so Czech standards and what is connected with safety control systems are discussed. This project is implemented in cooperation with industrial automation company ElektroMAR a. s.

Digital twin of a conveyor line
Sazonov, Viacheslav ; Lacko, Branislav (referee) ; Škrabánek, Pavel (advisor)
The bachelor's thesis is devoted to the creation of a digital twin of the transport line called Interoll, which will reflect the dimensions of the real model, information about the functionality of the drives and information about the correct functioning of the control logic of the whole system. The next section describes Industry 4.0 and the use of digital twins. Furthermore, the thesis deals with the design of a 3D model of a transport line, the creation of logic control and digital twin drives using software from the Siemens company. The output of the thesis is a properly functioning digital twin of the Interoll transport line.

Simulation of asphalt mixture ageing in laboratory
Staňková, Michaela ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis deals with the issue of ageing of asphalt binder and asphalt mixture. Asphalt mixtures of asphalt concrete type containing 50/70 paving bitumen were collected for the purposes of this thesis. Test specimens were prepared from the mixtures according to ČSN EN 12697-30+A1 standard. The test specimens were aged in a laboratory oven. Changes in properties caused by ageing were compared using particle loss of porous asphalt specimen according to ČSN EN 12697-17+A1 and the indirect tensile strength of bituminous specimens according to ČSN EN 12697-23 standard.
