Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Wireless temperature sensor with high temperature warning indicator
Dvořák, Petr ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
This thesis deals with a proposal of a wireless temperature-sensitive element at high temperature. It analyses some different variants of the temperature sensors. Furthermore, the thesis describes the Industry Science Medical (ISM) bands, in which it will be possible to communicate with the wireless communication modules. These wireless modules are discussed and described. By the devices „the transmitter and the receiver" it is focused on the communication of the microcontroller Atmel with the wireless modules, with the temperature sensors, microswitches on the control and display unit (LCD).

The use of thermovision technology in output control of power supplies
Rejžek, Jan ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The aim of the thesis is to clarify the issue of non-contact surface temperature measurement with a focus on the thermal imaging cameras as a modern representative of pyrometers and thermovision technology used in the output control of power supply. To obtain the corresponding results of temperature control, it is necessary to know the exact values of emissivity of the measured materials. The experimental part of this thesis is focused on detection of emissivity of power supply parts.
