Building Heating System Controller Using Zigbee
Mičulka, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This thesis is focused on the design and implementation of heating controller system of the model house. In terms of design is the emphasis on simplicity, efficiency and scalability. Implemented heating controller system includes a central controller unit and modules that are placed around the model house and can perform several functions - temperature measurement, control actuators or remote parts of the wireless link. This thesis describes the complete development from the initial system design through assembly of all elements of hardware, firmware implementations for each module type and a control program running in the control unit. It also describes the communication between system elements. Suitably chosen solution combines wired and wireless connections, depending on how it is ideal in terms of the model house. The whole system of functional prototypes was tested and the results were summarized in the conclusion.

System for Identifying Above Ground Level of Flying Objects
Boba, Peter ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
This master's thesis deals with design and development of a system for measuring altitude (height above ground level) of flying objects. It describes theoretical background related to altitude measurements in avionics as well as various techniques of altitude measuring. The measurement is conducted by HMD (Height measuring device) - embedded system which uses barometric pressure sensor to measure altitude. The main part of this thesis is dedicated to ground unit - a server running custom set of applications. Using this server and radio link, it is possible to send control commands to HMD, receive data, and propagate data into web application. Furthermore server acts as a data storage and is able to process and analyse data. The thesis also discusses the precision of the measurement and the data output. System was tested and used during several glider aerobatics competitions.

Usage of Modern Methods for Increasing Reliability of Control System Implementations
Szurman, Karel ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
At avionics control and critical systems is necessary guarantee a minimal level of fault tolerance and their high reliability. On the electronic components in these devices has an undesirable influence environment conditions and mainly cosmic ray. In this paper are described the most common failure types of semiconductor components and devices together with modern methods which can be increased the system fault tolerance and its overall reliability. There are introduced aspects of the avionic systems design due to finally certification and ways to evaluate its safety. This thesis describes design and implementation of the CAN bus control system for the FPGA platform which uses the CANAerospace application protocol. Created system design is improved by the TMR architecture. Fault tolerance of both system version is tested by the SEU framework which allows using the dynamic partial reconfiguration generate an SEU failures into running FPGA design.

Room Temperature Controller
Hruškovský, Antonín ; Tříska, Vít (referee) ; Mičulka, Lukáš (advisor)
This bachelor thesis deals with a production of a room thermostat for regulation of temperature in a house or flat. The text describes several types of sensors for measuring temperature according to various physical principles. Afterwards, one of the types of sensors has been selected and used in a measuring unit. Subsequently, a hardware design of the thermostat has been described, including the creation of the PCB design on a computer, component selection and the thermostat production itself. This is followed by the description of algorithms implemented on the microcontroller MSP430 to ensure the proper functioning the thermostat. A software has been installed into the side of the computer used to communicate with the thermostat. The communication with the thermostat has been realized by means of an USB bus.

FPGA-based MP3 player
Náplava, Tomáš ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
This work deals with the design and implementation of a hardware unit that is capable of playing MPEG-1 Layer III files, compliant with ISO/IEC 11172-3. There are given the benefits of using the MP3 format and principles that make it possible to compress the size of the resulting music recordings. The file format and all parts of the header are thoroughly studied as well as the method of encoding information. The process of the data decoding is divided into several consecutive, more or less discrete functional units and these units are designed and described in a hardware description language VHDL. There are also discussed features of FPGA chips - programmable gate arrays. Those are used for physical realization of the MP3 player. A development board is selected, including such an FPGA chip and other resources that allow synthesis of the entire circuit and playback in real time.

Application of Machine Learning Algorithms for Generation of Checking Circuits
Lelkes, Olivér ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
This bachelor thesis deals with application of machine learning algorithms for generation of checking circuits. It contains detailed descriptions of the individual algorithms of machine learning which have been chosen to achieve this purpose. Except familiarization with it's theoretical properties there are also parts devoted to the specific utilization of the mentioned algorithms in the form of classifiers. Classifiers can work with different settings which influence the accuracy of the learning and the subsequent classification. The differences between the individual classifiers and their settings are illustrated in the experimental part of the thesis. Experiments were conducted on various circuits, including the control units of the robot, developed on the Department of Computer Systems, Faculty of Information Technology, Brno University of Technology.

FITkit as Step Motor Controller
Čejka, Štěpán ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
This work deals with problems related to design and implementation of a stepper motor controller based on the MSP430F2617 microcontroller and the Spartan3 field-programmable gate array available on the FITkit platform. In the work, details related to types, principles, functions and stepper-motor control methods are described in detail. Proposed control units are designed to work in two different ways of control and operating modes of motor. Features of the control units have been tested with the SMR 300-100-RI/24 step motor by the means of a custom-designed pulse generator.

Methodology for Fault Tolerant Systems Design into Limited Implementation Area in FPGA
Mičulka, Lukáš ; Racek, Stanislav (referee) ; Vlček, Karel (referee) ; Kotásek, Zdeněk (advisor)
Tato práce popisuje navrženou metodologii pro návrh systémů odolných proti poruchám v FPGA schopnou ochránit systém před projevy přechodných a trvalých poruch. Oprava přechodné poruchy je prováděna částečnou dynamickou rekonfigurací. Oprava omezeného počtu trvalých poruch je založena na použití odolných architektur využívajících menší množství zdrojů než předchozí použitá architektura. Vadná část FPGA tak není dále využívána. Tato technika je založena na použití předkompilovaných konfigurací uložených v externí paměti. Pro snížení paměťových nároků pro uložení konfiguračních bitových posloupností je použita technika relokace.
