Design of evaluation network for in-vehicle networking communication chips
Kupčík, Ondřej ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Cílem této diplomové práce bylo navrhnout moduly určené k demonstraci a testování některých obvodů, používaných v automobilové technice. Jedná se o LIN transceiver NCV7420 a osmivýstupový výkonový budič AMIS-39101. Návrh spočíval ve vybrání a popisu parametrů vhodných podpůrných obvodů, vytvoření celkového schématu a navržení desky plošných spojů tohoto modulu s ohledem na kompaktní rozměry a předpokládané testy. Dalším krokem byla tvorba firmware řídicího mikrokontroléru (C8051F344), jež zajišťuje LIN komunikaci, řízení budiče a základní monitorovací funkce. Poslední část popisuje software pro hostitelský PC umožňující komfortní řízení sítě složené z těchto modulů. Pro úplnost byl tento projekt doplněn o přehled vlastností sběrnice LIN a metodiky testování LIN transceiveru z hlediska funkčních parametrů i některých EMC měření. V příloha obsahuje kompletní schéma modulu, výkresy desek plošných spojů, seznam řídicích příkazů a fotografie modulu.

Design and production of sample panels with system installation Ego-n
Vašíček, Martin ; Bátora, Branislav (referee) ; Macháček, Jan (advisor)
The thesis deals with the development of systems for intelligent building, focused on wiring system, division of them and comparison of their differences. The advantages of these systems like comfort, energy reduction, etc. are also mentioned. Nowadays several standards of systems for intelligent building exist as KNX/EIB or LON, therefore thesis concerns to trade-off these standards too. Main part of the thesis is focused on system Egon made by company ABB where the system concept as well as bus modules are described that allow different functions, mutual connection of modules and their programming. Tutorial panel with ABB Ego-n wiring system, which will be used for study purpose, is designed in the practical part of the work. It includes scheme of the panel, electric linkage of components and photographs of constructed panel as documentation. In the final part of the work two examples of laboratory exercise for installation and setting are listed, including programming description.

SystemC Memory Subsystem
Michl, Kamil ; Vaňák, Tomáš (referee) ; Hruška, Tomáš (advisor)
This thesis deals with the design and implementation of a processor simulation memory subsystem. The memory subsystem is designed using the Transaction Level Modeling approach. The implementation is done in C++ language utilizing the SystemC library. The processor simulation is adopted from the Codasip company simulator. The objective is to create a functional connection between the processor and the memory inside the simulator. This connection supports communication protocols of AHB3-lite, AXI4-lite, CPB, and CPB-lite buses. The new implementation of the aforementioned connection and the memory is integrated into the original simulator. The resulting simulator is tested using unit tests.

Comparison of design classic and smart wiring of house
Valo, Marek ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
This work contains requirements for the design of high-voltage and low-voltage classic and smart wiring. The aim of this work is to implement a project of classic and smart wiring for house and their subsequent comparison. In the beginning is introduction to wiring as such, insight into history, a brief presentation of contemporary species of wiring. The following chapter provides an analysis of high-voltage systems and criteria in its designing, which is based on the currently valid standards. The chapter contains also a brief excerpt dealing with ways of storing wires in buildings and installation zones individual rooms. Chapter of system wiring briefly describes the idea of this kind of wiring and its function. Introduction is focused on explanations of the system wiring, then the chapter directed to a specific producer used in the design of the project itself. In the chapter number five the problem of low voltage wiring and methods for their design are analysed. The following section deals with the design of wiring own project (classic and system) for a family house, designing switchboard, budgeting and technical reports. In conclusion, these two types of wiring are compared in terms of design, project documentation and budget. The practical part is dedicated to creating drawings containing high-voltage and low voltage wiring, switchboard scheme, budget, calculating illuminance and technical reports. The project documentation is discussed further in the technical report.

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.
