Simulators of balls and trunks laboratory models in Control Web
Chalupa, Petr ; Arm, Jakub (referee) ; Jirgl, Miroslav (advisor)
The aim of this bachelor’s thesis are creation of two program, able to simulate and visualize actions on laboratory models sorter logs and dosing balls. These models are used to learning PLC programing. In first part is deal with program Control Web. The next part describes both of models, their schema and functions. The following part describe creation and work of program, which I made. The last part of this work is deal with connection both programs with PLC by using MODBUS.

Computer tasks for subject Signals and Systems
Šimčík, Patrik ; Jirgl, Miroslav (referee) ; Jura, Pavel (advisor)
The content of this work is the design and implementation of tasks using MATLAB programming. These tasks are designed to describe and help the student understand some topics in the field of continuous and discrete signals and systems, which are presented in the subject of Signals and Systems at the Faculty of electrical engineering and communication technologies. From the theme of continuous signals are in this work outlined these problematic areas: analysis of periodic and aperiodic functions, continuous systems and from the theme of discrete signals are selected areas: analysis of discrete signals and discrete systems of first and second order. In the practical part the realization itself is described using a graphical user interface (GUI).

Modernization of Vulcanization Press Control
Sáblík, Patrik ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This thesis deals with the design of the controller system for modernisation of operating the vulcanising press with the usage of the control through the PLC designed by Teco a.s. First part of the thesis describes requirements and functions of a vulcanising press. It contains a background research of needed components from three different producers of the PLCs. Next step is a design of the operating system. It contains the PLC programme and design of the regulators of the press forms temperature. The last part is concerned with wiring of all the components, their activation and checkingout eventual failures of the designed programme.

Proposal of electronic security system with intelligent home elements
Kůtka, Michal ; Hynčica, Ondřej (referee) ; Jirgl, Miroslav (advisor)
The bachelor thesis deals with an electronic security system for the protection of the family house. This bachelor thesis was commissioned by ULIMEX, spol. s r.o. for the purpose of summarize information and expanding the range of products the company mainly components for smart home and home automation. Bachelor thesis contains a theoretical introduction to electronic security systems. In detail there is described norm ČSN EN 50131-1 ED.2 that defines the various security division, but also the requirements for the security system. Part of the thesis was conducted exploration of the Czech market and compared to the biggest rivals of security system Jablotron 100. In this thesis is described in detail the security system Jablotron 100 along with their components to ensure safety, as well as components for the implementation of solutions in the smart home and home automation. Part of the thesis is also the project documentation of the design of electronic security system for the house of the new generation, which is included in the Annex I and Annex II to this document.

Application for the HAWK regulator
Kvasnička, Petr ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis deals with the issue of intelligent buildings management and practical use of the control system HAWK from company Honeywell. The thesis describes the basic problem of intelligent building management, exactly why they created and how it is possible to implement building automation, including a listing of available equipment that can be used in these systems. The thesis also discusses one of the systems that can be used for building control. The control system is called HAWK and thesis describes the programming environment and connectable peripherals. For a given control system is formed in the scrubbing practical demonstration device wind tunnel, which is shown using the work of the control system.

Reliability of Technical Systems
Jirgl, Miroslav ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This thesis deals with a reliability of technical systems. It is divided into four main parts. The first part deals with the mathematical description of reliability. Probability and statistics are used for this description. This part includes the definition and properties of random events, the description of discrete and continuous random variable and its distribution. The second part contains the definition and expression of reliability, types of faults in the digital circuits and the reliability of electronic components. This part introduces into problems of reliability. The third part includes making the reliability diagrams and reliability analysis. Each method is briefly described here. Further advantages and disadvantages of using each method are given here. The two most widely used reliability analysis - Failure Mode and Effect Analysis - FMEA (resp. FMECA) and Fault Tree Analysis – FTA are described in a greater detail. The last part focuses on an example of calculation of reliability. An analyzed object is Universal Charger NiMH and NiCd batteries. Reliability is analysed by block diagram, FTA and FMEA.

Modelling and prediction of reliability
Jirgl, Miroslav ; Jalovecký,, Rudolf (referee) ; Havlíková, Marie (advisor)
This thesis presents a reliability analysis of a technical system. It is divided into three main sections. The first section introduces some of the most significant problems of reliability. It deals with a definition and an expresion of reliability, a reliability diagram selection and a detailed description of the reliability analysis. This part also includes an overview of reliability analysis types. Some of the most widely used reliability analyses are briefly described; further advantages and disadvantages of using each method are listed. Failure Modes and Effects Analysis - FMEA is then described in a greater detail. The second section contains an analysis of aviation conditions as well as a design of a reliability analysis that concerns a selected digital system; the system under analysis is a pitch trim indicator. The main design issue lies in a choice of a most suitable method. This choice stems from the overview of reliability analyses presented in the first section of the thesis. In the last section, a FMEA reliability analysis of the pitch trim indicator is conducted. This part includes a discussion of the results as well as a design action that is to lead to an increase in reliability of the analyzed system.
