Systme for solar system control
Cseri, Peter ; Šembera, Jaroslav (referee) ; Bradáč, Zdeněk (advisor)
In the first part of my thesis, I was studying materials about using solar energy. Then I write search about all components that are necessary to be used in solar systems. After that I designed the structure of solar system used for heating the hot water for a family house about 4 persons. For this system I designed a regulator and one layer circuit board using Eagle layout editor 4.12r2, which I assembled and tested. This followed creating and debugging program for microprocessor that controls the whole device. This functional regulator for solar collectors connected in a box together with the necessary electronic components is my final product of this project.

Drive model for EC motor elevator analysis
Javořík, Zdeněk ; Koláčný, Josef (referee) ; Vondruš, Jiří (advisor)
The master thesis encompasses the possibilities of position evaluation and drive control with the aid of SMI work enviroment. Furthermore the thesis is directed to create a program through a designed control algorithm. The work is realised on the elevator model with electronically commuted motor. An incremental scanner is used as the position sensor. The motor control unit is set up and programmed in the SmartMotorInterface software. In the next part, measurements with altered parameters are conducted. On the basis of these measurements the influence of parameters on the positioning process and its accuracy is evaluated. At the conclusion of the work, a design of laboratory task for educational purposes is created. The laboratory task is composed in such a way, that students would become familiar with the SMI work enviroment and would be able to practicaly test the setup of incremental position sensor and motor control with the aid of entered algorithm.

Universal hardware platform supported Linux operation system
Skopal, Miroslav ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
This thesis deals with the development problems and creating of the multi- purpose hardware platform, which supports operating system Linux. It is focused on the microprocessors using ARM architecture with architecture ARM7, ARM9 and ARM11. The scope of the first part of this thesis was searching the sales of available 32 bit ARM microprocessors. The second part is attended to a particular Mini2440 development kit, its animation and the subsequent development of the kernel drivers for OS Linux platform. One of this thesis details was also the development of my own expansive hardware module and a capacity keypad for a usage with Mini2440 developmental kit.

Measuring temperature in the photovoltaic systems
Vičar, Pavel ; Vaněk, Jiří (referee) ; Veselý, Aleš (advisor)
This diploma thesis deals with covers design and realisation of device for multipoint temperature measuring in fotovoltaic systems. As a controlling microcomputer is used Atmel ATMega128L, temperature sensors are realised by DS18S20 digital thermometers, connected via 1-wire bus. System can read temperature from x temperature sensors, includes memory for measured data, real time clock and display with buttons for basic user control. Temperatures are measured periodically, values are stored into internal memory and showed on display.Measured data can also be transferred via seriál bus to clinent PC. Device is projected as a battery-operated compact tool. The final realization is made with respect to minimal system requirements and to possible future extensibility for wider usage spectrum.

Atmel AVR32 UC processor demo application
Zajíc, Jakub ; Hanák, Pavel (referee) ; Fedra, Zbyněk (advisor)
The diploma thesis provides a brief overview of the architecture Atmel AVR32 UC. Project deals mainly AVR32 processor UC3A and processor AVR32 UC microarchitecture. From The Microarchitecture AVR32 UC3A was derived processor AT32UC3A0512. This processor is used for the development board EVK1100. Options of this plate are also investigated. Basic information about programming and AVR32 Studio development environment for these processors are given. After the acquisition of control of the IDE and study the attached sample application a simple program was created. This program was integrated as a task operating system FreeRTOS along with several another tasks.

Universal diagnostic device for accumulators
Němec, Filip ; Lattenberg, Ivo (referee) ; Balík, Miroslav (advisor)
Firstly, this bachelor thesis handles the issues concerning NiCD and NiMh batteries and methods used when charging and discharging. Next segment of the document deals with designing and the actual realization of a device, which can work with these batteries and perform variable tasks,such as charging and discharging battery with adjustable current value, measuring temperature of the battery. Sending data via the serial port,it also implements charging and discharging curve. Device can be operated intuitively using buttons and display. The Device is realized via microcontroller ATMEL.

Wireless Sensor Network with Atmel AVR Microcontrollers.
Mráz, Ľubomír ; Kouřil, Jiří (referee) ; Šimek, Milan (advisor)
This diploma thesis describes the standard IEEE802.15.4 and Zigbee for wireless sensor networks. These norms are described in detail in the first two chapters. The main priority of the wireless sensor networks is to minimize the power of the devices and the price while maximizing the reliability of the data transfer. Minimum consumption is provided by the significantly lowered complexity in comparison to the standard wireless networks. Further, the design of the concept of the complex and universal hardware platform focused on intelligent building is described. Software implementation of those norms is described in the chapters five and six. Finally, comparison of the designed hardware platform and the other commercial platforms is described in the last chapter.

Altitude meter for RC models
Beneš, Jan ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
Altimeter measures atmospheric air pressure and counts actual model altitude from it. Then sends data to ground module, which shows them on display. Ground module contains USB interface for connecting to PC. It enables upload of flight data and opportunity to show them in graphical representation.
