Design of universal motortester for car servis
Vařeka, Libor ; Chorý, Tomáš (referee) ; Křenek, Ladislav (advisor)
The aim of this dissertation is to focus on the systems design of a multi purpose engine tester, a device for diagnostic techniques of self propelled motor vehicles to be used in a car mechanics work shop. The principle aim is to combine a permanently installed PC, a portable laptop and a workshop trolley containing all the necessary assembly tools and accessories. These three pieces used together will serve as a self contained unit within the workshop. I will compare the quality of the devices with others on the market. I will talk about the layout of the individual parts such as the design, structure and shape of the unit, as well as the ergonomics of the designed pieces. An important factor will be reducing the size of the device without compromising the quality and keeping it a similar price to other similar products on the market.

Traffic monitoring using Raspberry PI
Zacpal, Michal ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis describes the design and subsequent implementation of a unit for traffic monitoring using Raspberry PI. First section provides a quick overview of assistance systems, which use a road lane detection techniques. Next there is a description of two diferent methods for road lane detection. Follow the description of monitoring scene. Then the work describe the practical part including the design and realization of supporting electronics, selecting of each components, including the modifying of cameras, mechanical design and creating of unit. Another section is about selection and installation of appropriate software components necessary for running of the unit and the selection of development tools for creating user application. After description of graphical user interafce, there is a description of road lanes detection algorithm. At the end of the thesis is summarized a reliability of unit in real traffic situation. At the appendix there are technical drawings, describing the unit.

Attendance System Terminal
Chmelař, Jakub ; Mráz, Ľubomír (referee) ; Strašil, Ivo (advisor)
This thesis deals with electronic attendance systems which are nowadays being widely used to record employee attendance. General problem of attendance tracking is introduced in first part of the thesis along with a conceptual solution of an attendance system terminal. Author then describes a circuitry and a PCB design of a baseboard for a Cubieboard2 minicomputer, a RFID reader and a touchscreen LCD display. After successful testing of said PCB, the terminal has been completed and it was possible to focus on a software solution. Latter part of the thesis is dedicated to a specifics of the Allwinner A20 platform and its support by a GNU/Linux operating system. In following chapter author describes use of a Buildroot software for creating a Linux based binary image for an aforementioned minicomputer. Since an operating system and a peripheral support were successfully tested author could focus on a design and implementation of an attendance software that is described in the final chapter.

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

HMI automatic tester
Lang, Stanislav ; Žalud, Luděk (referee) ; Macho, Tomáš (advisor)
This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.

Communication & Man-Machine Interface for industrial sensors
Marcoň, Petr ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
This thesis describes the possibilities of local and remote sensors configuration. Summary overview of the most common Fieldbus and protocols for remote configuration is performed. The focus is mainly dedicated to the HART protocol that is analyzed from the physical layer to the application layer. Circuit diagram and printed circuit board (PCB) of smart sensor with thermistor probe Pt1000 was designed. The HART protocol allows the smart sensor parameters setting as well. The functionality of remote configuration was tested in HARTWinConf program. The control elements for local sensor configuration, such as buttons, matrix keyboards and touchscreens, are described in the following chapter. Representation of the measurement values on display module is introduced too. The most important parameters and aspect of character LCD, graphics LCD and OLED displays are described in greater details. The DD12864YO-3A OLED display was selected to use with designed temperature smart sensor module. The display shows the loop current, the percentage of current range and the primary value - temperature. As the last step the EMI and EMS tests for all modules were performed.
