Power-line network communication
Sláčik, Ján ; Rášo, Ondřej (referee) ; Kolka, Zdeněk (advisor)
The master’s thesis is dealing with PLC technology and its modem realization based on several types of standards by using commercially available integrated circuits. This projects also describes fundamentals and prerequisites for building the PLC network fulfilling the European standard CENELEC. The work further describes designed system concept, which serves as the automated system for the appliances connected to an electrical network. Components are selected for implementation and then is introduced concrete solution and implementation power-line network. Within the work are then other parts, that together form a system concept. Work includes the hardware and software implementation and a description of the options implemented system.

Methods for testing of analog circuits
Kincl, Zdeněk ; Vlček, Čestmír (referee) ; Husák, Miroslav (referee) ; Kolka, Zdeněk (advisor)
Práce se zabývá metodami pro testování lineárních analogových obvodů v kmitočtové oblasti. Cílem je navrhnout efektivní metody pro automatické generování testovacího plánu. Snížením počtu měření a výpočetní náročnosti lze výrazně snížit náklady za testování. Práce se zabývá multifrekveční parametrickou poruchovou analýzou, která byla plně implementována do programu Matlab. Vhodnou volbou testovacích kmitočtů lze potlačit chyby měření a chyby způsobené výrobními tolerancemi obvodových prvků. Navržené metody pro optimální volbu kmitočtů byly statisticky ověřeny metodou MonteCarlo. Pro zvýšení přesnosti a snížení výpočetní náročnosti poruchové analýzy byly vyvinuty postupy založené na metodě nejmenších čtverců a přibližné symbolické analýze.

Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

System for precise dynamic measurement of bridge sensors
Čech, Jonáš ; Kolka, Zdeněk (referee) ; Kubíček, Michal (advisor)
This master’s thesis deals with design of measurement system for dynamic measurement of bridge sensors. After a short theoretical part, the own concept is introduced. System can provide sampling rate up to 250 kSa/s with 24-bit resolution. The maximum number of samples is about one and a half milion. At first, the design of analog part was made, in this phase of design the digital part is based on evaluation board with ARM Cortex-M7 and external memory. After final choice of appropriate ICs, the analog and digital part will be integrated into one PCB.

USB miltimeter with microprocessor
Samek, Martin ; Kolka, Zdeněk (referee) ; Kovář, Jan (advisor)
Topic of my terminal labour is a proposion of multimeter and its resulting connection by the help of bus USB. When proposing the multimeter there was a tendency to use a minimal number of component parts to conserve a good protection against a bad usage in application. The most widespread busbar USB is used for connection of the multimeter and a computer. Standard HID is used for communication, for that it is not neccessary to install any system drivers.

Meter of powerline quality
Samek, Martin ; Horský, Pavel (referee) ; Kolka, Zdeněk (advisor)
The subject of graduation thesis is a design of line analyser according to standard EN61000-4-30 class A. The analyser is determine to be used for quality control of supplied electric power which is, during electric power transmission, affected by several disturbances. Power line analyser should measure single-phase and three-phase network parameters in LV and HV systems. Measured parameters can be shown on the full colour TFT display, stored in the device memory or sent to other devices such as PC. For communication between the device and PC the USB, Ethernet or RS485 interface are used.

Model of computer network in MATLAB/SIMULINK environment
Zedníček, Petr ; Zeman, Václav (referee) ; Kolka, Zdeněk (advisor)
The bachelor thesis deals with simulation of TCP protocol behaviour in Wireless optical environment. The thesis examines the various parameters of the protocol and evaluates their response to the transmission speed. The key objectives of the thesis are the introduction to the problems of communication, specially the description of the transport layer architecture, TCP / IP and congestion management mechanism NewReno. A large part of the thesis is devoted to modelling communication points and a model of optical wireless connections. The results will be applicable to create a new communication protocol for Wireless optical environment.
