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.

HIL test stand for universal electronic control units
Zouhar, Štěpán ; Musil, Filip (referee) ; Brablc, Martin (advisor)
This diploma thesis is focused on testing of Electronic Control Units, especially functional testing in which hardware and software is verified and also Model in the Loop, Software in the Loop, Processor in the Loop and Hardware in the Loop testing methods. Within practical part of this thesis testing stand for functional test of the ECU was developed and manufactured. It is connected to PC via Input/Output card, testing is controlled by MATLAB script. Whole process of testing is automated from initial upload of testing firmware to tested ECU over all phases of test up to bootloader flashing. Hardware in the Loop test was also created, in which ECU works as controller and DC motor is simulated in real time with PC in MATLAB environment.

Segway driver parameter estimation and its use for optimizing the control algorithm
Dobossy, Barnabás ; Zouhar, František (referee) ; Brablc, Martin (advisor)
Táto práca sa zaoberá vývojom, testovaním a implementáciou adaptívneho riadiaceho systému pre dvojkolesové samobalancujúce vozidlo. Adaptácia parametrov vozidla sa uskutoční na základe parametrov vodiča. Parametre sústavy sa nemerajú priamo, ale sú odhadované na základe priebehu stavových premenných a odozvy sústavy. Medzi odhadované parametre patrí hmotnosť a poloha ťažiska vodiča. Cieľom práce je zabezpečiť adaptáciu jazdných vlastností vozidla k rôznym vodičom s rôznou hmotnosťou, kvôli zlepšeniu stability vozidla. Táto práca je pokračovaním predchádzajúcich projektov z roku 2011 a 2015.

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.

Methodology Development and Validation of Software for Safety-Related Parts of Control Systems in Theater Technique
Drlík, Michal ; Suchánek, Rostislav (referee) ; Sinay, Juraj (referee) ; Blecha, Petr (advisor)
This thesis describes what the theatre is and what types of machinery can be found there. Then the issue of stage technical machinery is presented into the czech context, respectively into the Europian legislation with the emphasis on the technical norms usage, which are necessary to fulfil in order to reach this aim. In the next part of the thesis is made the analysis of control systems, which are used in the stage technics with the emphasis on the functionality of these control systems, since this functionality determines number and range of possible danger and dangerous events, later on. These dangerous situations are named and specified in detail, thereby their existence, importance and necessity of solution is being emphasized. There is also a possible solution outlined that these dangerous events can be solved in many cases by using of these programmable systems relating to the safety, thereby safety functions realized by these functions. Then the single steps are described into V-model with appropriate documents of these V-model steps. Outcome of this thesis will be suggested model of method and its development and software validation for programmable and control systems in theatre technology.
