Power Line Communication for Home Automation Applications
Hromádka, Michal ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
This thesis describes the design of a modem for a communication over residential power lines. First part is focused on the history, suitable frequency bands, modulation techniques and mainly on the selection of the optimal modem device. Second section contains the description of the hardware design of the modem itself and clarifies the implementation of the PLC module to be used as a communication interface for a full residential automation solution. Last chapters of this thesis introduce the communication protocol, design of the software for the ATmega32 MCU and present of the final field testing under real conditions.

I2C Bus to RS232 Bus Convertor
Votava, Martin ; Marvan, Aleš (referee) ; Orság, Filip (advisor)
The main goal of this Bachelor's thesis is to create I2C bus to RS232 bus convertor. Using I2C bus the convertor drives 8bit I/O expander. In theoretical part buses I2C and RS232 are described along with PCF8574. There is also mentioned selection appropriate microcontroler and design of comunication protocol. Practical part is dedicated to creating control program for microcontroler, appropriate comunication protocol processing and convertor testing. There are also described some auxiliary products and program testing.

Tools for Environment for the Simulation of Communication
Mikuš, Peter ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
Communication between devices should be based on predefined rules. These rules are called communication protocols. In this master thesis I am concerned with communication protocols, specially security protocols. Their design demand specialized tools, that will provide interactive simulations and security testing. I have described each of these tools in detail and mentioned about their properties, their pros and cons. In available tools I have implemented security protocols. The result is set of demonstration tasks that are usable in network courses at FIT VUT

Home security system - remote access module
Šarda, Petr ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
This thesis deals with remote access module for electric security systems (ESS). The design is based on valid standards that apply to a production of electric security system. It includes a design of module connection to the central that controls the module. There is also a communication protocol for connection with the central and with the user. The last step is development of web interface, which is realized on the selected development kit.

Communication protocol implementation into signal processors
Červenec, Radek ; Daněček, Vít (referee) ; Herman, Ivo (advisor)
Práce se zabývá studují, modifikací a návrhem komunikačních protokolů a jejich implementací v digitálních signálových procesorech v jazyku instrukčních adres. Také zkoumá strukturu elektro-akustické jednotky EPIS 2.45. Popis jednotky je zaměřen na její softwarovou část a to zejména na operační systém založený na kooperativním multitaskingu. Pro dosažení úspěšného návrhu a implementace komunikačních protokolů se práce zaměřuje také na základy vícevrstvé síťové architektury. Poté je již zkoumána skutečná síť (Koris Net) společně s jejími, ale i dalšími komunikačními protokoly, jako například protokol Modus. Popis je doplněn o příklady zdrojového kódu jejich implementace v digitálním signálovém procesoru (ADSP 2191M). V práci je mimo jiné prezentován navržený komunikační protokol pro vyčtení souboru z palubního počítače připojeného k jednotce na sběrnici Modus. Společně s tím je také obsažena navržená úprava protokolu, tak aby bylo možné předávat stažené soubory přes radiové rozhraní do centrálního počítače.

Universal Bootloader for Kinetis K60 Microcontroller
Krůpa, Tomáš ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The scope of this work was to design a bootloader for Kinetis K60, an ARM Cortex-M4 microcontroller. The bootloader should simplify the process of loading user applications to the flash memory of the microcontroller on the Minerva development kit. Based on a quick research of existing bootloader solutions, new bootloader was designed together with communication protocol that would suit the needs for transfer of both the file data and configuration information through all the supported communication interfaces - USB, SDHC, Ethernet and RS-232. On the PC side, development of bootloader’s application library and two supporting utilities with graphical and command line interfaces was made. The system can be used out of the box as well as it can be further extended in the future.

Interfaces of Web-Services
Kubát, David ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
The objective of this thesis was to get acquainted with the proposition of the service-oriented architecture and its real representation web services. To understand the principles of their functioning, creation, communication and the ways to finding and using them. To be specific, the goal of this project was to analyse a current program, design its transfer to the web service description language and to implement a web service interface layer upon this program. The system is demonstrating the basic principles of the web services and the function of the interface during the communication between its provider and customer.

Autonomous mobile robot
Pijáček, Ondřej ; Kopečný, Lukáš (referee) ; Jílek, Tomáš (advisor)
This thesis describes the design and implementation of chassis for autonomous wheeled mobile robot along with a proposal for a suitable control system. To move the robot was necessary to create individual modules for measuring environmental data, its subsequent processing and power management. For the entire robot system capable of rapid interaction, certain tasks are separated and controlled by its own microcontroller. For communication between the modules were chosen and designed SPI bus communication protocol. Thus assembled chassis then communicates over a serial line with higher system from which acquires data indicative of a subsequent procedure. The result is a controlling system communicating between its parts. Part of the design is also defined communications protocol that transmits data on the one hand and also used for fault diagnosis when sending information. Furthermore, there are patterns and specific methods for controlling the individual modules. In conclusion, the thesis described the proposed testing the robot in real conditions, along with the measurement results obtained in the task of autonomous driving.
