Design and production of sample panels with system installation Inels
Steidl, Jaromír ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
Diploma thesis deals with the problems of system installations. The system installation is presented as an installation, where the light switch does not serve for interrupt a power circuit, but it serves as a sensor, which directs the status change of actuator, that makes the own manipulation with a power circuit. In the first chapter the diploma thesis presents the history of the system installation development depending on the demand for the system regulation in buildings centrally and complexly. There are also summarize advantages and disadvantages of installations, which are used in these days. In the second chapter, the system installations are devided into centralized and decentralized systems. The centralized systems are constructionally simpler as well the communication, but the whole system is more inclinable to fail. The decentralized systems are more complicated, more expensive, but more reliable and they have also potentiality to extand. Two decentralized systems, nowadays the most used, are further presented – KNX and LonWorks. They are used especially for the administration buildings control. Then the diploma thesis presents both some systems, which are used abroad, and the situation at the Czech market, whereas there is described the system INELS, which is made by Elko ep. Limited Company. The goal of the thesis, which is mentioned in the third chapter, is to present the system installations, design a panel with this installation including the panel´s handmade, and then on this panel demonstrate the panel´s using for education in laboratory practices. The fourth chapter discusses the author´s characterization of the panel´s concept – there is described the graphical concept of the panel, used units and their integrations. By all of used units their functions on the panel are described. In the last but one chapter, there are mentioned the practical applications, which the panel serves, and there are also described the concepts of laboratory tasks for education of the fundamental configuration and possibilities of the system installation INELS. The chapter also engage in the configuration of the system for the panel, which presents control elements in one room via the system installation INELS. This configuration serves for the presentation of the educational panel. The conclusion is dedicated to the summary of the mentioned problems.

Classical versus intelligent electrical installation
Haluza, Miroslav ; Brázdil, Vlastimil (referee) ; Macháček, Jan (advisor)
This work topic is development and history of intelligent wiring systems in Czech Republic as well as abroad. The firs paragraphs describe following: intelligent wiring systems, the differences between classic and intelligent wiring systems and consequently is described the intelligent wiring system itself (types, principles, advantages, disadvantages etc.). Detailed description of system Inels follows in the next chapters. This system is supposed to be the fundamental matter of this work and is used in consequent suggestions for intelligent wiring system that is defined at the end of the theoretical part of this work. At the conclusion the economic evaluation of various wiring options and assessment by the multicriteria analysis (MCA) will be provided.

Universal Analyzer of Serial Buses
Gajdoš, Matúš ; Hanák, Pavel (referee) ; Sysel, Petr (advisor)
The purpose of this master’s thesis is to design and to realize the universal analyzer of serial buses. At the beginning there are described in detail specifications and properties of buses IC, SMBus, PMBus and of the UART interface. The second part is targeted especially to design and to realize the control unit, which is the main part of the whole analyzer. It provides connecting to the unknown bus, to buses IC, SMBus, PMBus and SPI and to the UART interface. The main part of the control unit is the microcontroller PIC24HJ128GP204, which partially analyses connected bus. In the next part there is created the user application for PC, which controls and sets the control unit and receives from it partially analyzed data through the USB port. These data are used for the rest of the analysis that is done by the user application. Results may be presented to user in graphical or text form. The user application provides export of results into some of image formats. Supported formats are PS, SVG, PDF, PNG and BMP. In case of the control unit is not available, the user may choose the simulator to simulate some functions that the application provides. It supports simulation of the analysis of the unknown bus and the IC bus. The user application also contains the function of the generating own signals. Signals can be created interactively by using the mouse in the graphical representation of this signal. They can be sent to the control unit and after that it applies them to output. This function is not supported in current version of the control unit software. The user application includes some items, which do not have implemented any methods and they are prepared for the future upgrading of the analyzer. It means especially user controls and components for signal conversions between any buses.

System for acquisition of data from car communication system
Pecha, Michal ; Kučera, Pavel (referee) ; Fiedler, Petr (advisor)
The thesis contains complete design of complex system for acquisition of data from bus of a vehicle. It resolves problems of connection of a new node to CAN bus of a vehicle, communication protocol NMEA 0183 of GPS receivers, logging of caught CAN frames into database system MySQL, and proposes algorithms of application for operation of the system. It includes also process of complete installation based on established concept and test results of the system in real situations.

Design of the LVDS bus with hight EMC immunity
Klauda, Zbyněk ; Fiala, Pavel (referee) ; Kroutilová, Eva (advisor)
My thesis deals with project of LVDS busbar with high resistivity with regard to disturbance from surroundings and radiation undesirable electromagnetic waves into its environment. Project of LVDS busbar was elaborated by numeric methods and it was suggested optimal solution of the shape and material of multiply technology DPS. The project was realized on desired driving-point impenance of busbar Z=100 ohm with frequency f1=100 MHz of the first harmonic component rectangular signal of defind modality, entering and diagonal edge.

Communication with external devices by I2C bus
Prax, Jakub ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
This diploma paper deals with the data bus line I2C and a supportive demonstration tool for the subject Microprocessor technology taught at the Radioelectronics faculty. The data bus line I2C is convenient when short-distance data transmission with restricted spatial possibilities is required but high velocity of data transmission is not necessary. The tool is compiled in such a way that enables it to also perform other tasks apart from those dealing with the I2C data bus line. The data bus line in the tool is utilized for transmission of date, time, temperature, data for the D/A converter, data from and to the EEPROM memory and data to 16 bits expander.

Perspective bus powertrains
Kubík, Jan ; Maršálek, Ondřej (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to consider possible future development of alternative powertrains with regard to their use in buses. First described are the most promising alternative fuel vehicles, which use an internal combustion engine. The next part is evaluated ways to store energy using electric drives. At the end of the work is mentioned hybrid technology as a combination of previous drives.
