Inteligent battery charger controled by microcontroler
Burda, Petr ; Magát, Martin (referee) ; Pavlík, Michal (advisor)
Universal, smart battery charger NI-Cd, NI-MH, Li-Ion a Li-Pol batteries with adjustable voltage incremental rotary position sensor in the range of 0 -25 V and currnet up to 1 A load.The charger is controlled by microcontroller ATMEGA32 – 16PU Atmel and provides thermal protection and management of the chrging voltage depending on the temperature inside the battery pack or battery cells. Setting is made througth LCD screen to be displayed in addition to the set temperature, charging voltage and battery current. To save the profile is used EEPROM memory, which is contained in the microcontroller.

RFID bus-stop identifacation for sightless people
Straka, Radomír ; Zamazal,, Michal (referee) ; Dušek, Martin (advisor)
The aim of this master’s thesis is to design a device for identification of bus stops for blind people. In the beginning the work describes information about the RFID system, characterizes each part of this system, mutual communication of its components and evaluates possibilities of RFID communication frequency bands. Subsequently the work describes the block diagram of the device and the circuit scheme of each block. Work concentrates on a selection of circuit components for the RFID transceiver, the voice module, the control module and choose a suitable transponder to place it on metal constructions. Control programs are also described. PCB design of each board, partlists and source codes are in the appendices of this master’s thesis.

Control and monitoring of climate in groups of terrariums
Pavlišin, Tomáš ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
The aim of this master thesis is to propose a system for monitoring and regulating the climate in groups of terrariums using the Raspberry Pi platform and subsequent transparent display through the web server. Each group of terrariums has its own control device that wirelessly communicates with the Raspberry Pi control computer. The measured values are stored in the MySQL database on the control computer. The measured values are graphically displayed on the web page.

Rationalization of the concept of photovoltaic power station connection
Svozil, Marek ; Otava, Lukáš (referee) ; Blaha, Petr (advisor)
This masters thesis addresses the racionalization of the concept of photovoltaic power station connection. A way of compensation valuable components involvement standar- tizovaným inverter controlled by a microcontroller. Also includes the measurement of voltage and current using a microcontroller. The output voltage of the DC/DC con- verter is controlled by the variable duty cycle of the PWM signal generated by the microcontroller ATmega32.

Flip-dot matrix display
Petřek, Miroslav ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with the design and implementation of a control system that complements the existing BS110 flip-dot display panel and enables Ethernet and wireless communication. It first briefly discusses the original use of the display, and gives an overview of the display types. This is followed by an analysis, testing and repair of the BS110 panel, followed by a description of the proposed concept and the development of the control computers and their circuitry. For these, the thesis further describes the design and implementation of the software consisting of a website, database, MCU control script and display circuit control program. Finally, the system so designed and built is demonstrated and evaluated.

Robotic manipulator
Navrátil, Luděk ; Fedra, Zbyněk (referee) ; Mego, Roman (advisor)
The project target was to design a control system of the robotic manipulator with a computer vision. The experimental manipulator was made in this project. The electronic control unit was also designed to receive instructions from the PC, process them and to generate signals which controll the manipulator. The PC program is another part of the project. It is able to perform the calculations which are necessary for an accurate control of the manipulator, and find objects in a web camera view and direct the manipulator to them. The program is also able to handle input values which were entered by a user and communicate with the control unit.
