Industrial state indicator
Růžička, Zdenek ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Diploma work deals with industrial display systems, indicators and their proposal. These systems are used everywhere that is necessary to mediate transmission of information. Own proposal of indicator is very specific and depends on given application and used display. In practice there is possible to use a few types of displays but in this diploma work there are used only sedmisegmental and matrix. Common component of proposal is microcontroller. No less significat and important part of the proposal is a choice of interface and communication protocol. The correct choice of hardware that is completed with software we will obtain complete status indicator.

HC08 Microcontroller Development Kit
Hájek, Ondřej ; Sekora, Jiří (referee) ; Čížek, Martin (advisor)
Presented bachelor degree programme is aimed on design and implementation of a development board for Freescale HC908QB8 microcontroller from HC08 family. The board will allow the user to test a variety of typical microcontroller applications including temperature measurement, intelligent LCD interfacing and I2C bus communication. The development board can be programmed using universal DBG08 serial programmer. Care was taken to minimize the probability of an accidental misconnection causing potential damage to the circuit, which makes the device suitable for educational purposes.

Algorithms for decoding the Reed-Solomon error control code
Tieftrunk, Tomáš ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
Thesis discuss about effort to ensure from error, which may occur during transmission over noisy channel. There's used Reed Solomon code. It's block, cyclic and systematic code, which is symbol orientated. Computational process of decoding is mathematically time-consuming. In thesis is closely described Berlekamp-Masey algorithm, used in decoding to evaluate error polynomial. Process is illustrated in application in Matlab. Practical realization uses Reed Solomon code in communication over RS232. Communication is established between computer and microcomputer.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Design and implementation of modules for teaching and developing applications with microcontroller Atmel AVR
LANGMAJER, Miroslav
This thesis is based on the design and production of teaching kits with expansion modules which are based on the Atmel AVR microcontroller. Kit consists of a plate containing processes and basic power modules directly on the board and expansion modules "SIMAČ". "SIMAČ" modules are virtual elements that simulate the real elements and they are commonly used in industrial automation. Because of their cost they are integrated in extension kit as programmable modules. It also contains basic theoretical information about working with ATMEL AVR microcontrollers. Expansion modules with module development board and disc which will be loaded all the schemes, programs and technical documentation for individual districts will be attached to the thesis.

The use of cards with RFID technology for secure functions of production equipments
MASOPUST, Jiří
The thesis deals with the use of cards with RFID technology to secure functions of production equipments. The objective of this work is development of the system which use plant RFID cards to secure some functions and modes of production equipments. This solution uses Programmable Logic Controller in the machine for reading cards and manage card users. For this purpose it was necessary to develop both hardware and software parts. Hardware part contains description of all used devices and details about communication process. In software part there is a description of Graphical User Interface and software layers.
