Meassuring system for building constructions
Flagar, Vojtěch ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This paper deals with the hardware and software design of the data acquisition distributed system with large amount of connected sensors. The intended application of this work is measuring some physical quantities in the building constructions. The designed system is hierarchically divided into the three levels. On the highest level there is a single-board computer Raspberry Pi which is used as a master on RS-485 bus. There can be up to 32 slave devices on the bus while each of them collects data from the sensors connected to 4-channel I2C bus. At the same time the Raspberry Pi is used as a web server, providing the user interface of the system.

Analysis of Water Consumption
Pokorná, Denisa ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The subject of the bachelor thesis is the processing of water consumption analysis in the area of building faculty. The bulk of the work is devoted to the evaluation of the data obtained by the smart metering system, which is currently only installed on the billing water meter number 2 located on Veveří Street. The Faculty of Civil Engineering is very interested in new trends and possibilities to more effectively measure water consumption. The conclusion of the thesis deals with the appropriate design of the alarm values of consumption and the possible counting of other water meters in the area and associated faster and more transparent information about the water consumption values. An integral part of the work and water consumption are general information on the need for water for which there are no up-to-date comprehensive methodologies to accurately determine it. Analyzing already measured data seems to be the most accurate way of determining it. Part of the thesis is also a chapter focused on the development of water consumption in our country as well as in comparison with abroad. At present, there is a decreasing trend in water needs that began in the 1990s.

Data storage system for area of civil aviation
Kotulič, Dominik ; Novák, Lukáš (referee) ; Šteffan, Pavel (advisor)
In the thesis the design of the Data Storage System (DSS) is proposed with the respect to the V-Model methodology. The design is based on users requirements, from which the system requirements are created and the technical specification of the DSS is developed. In the technical specifications the functionality of the DMM and HMI DSS subsystems are described and sub-system requirements are assigned to them, then they are subdivided and assigned to individual DMM (Data memory module) and HMI hardware items. Moreover, requirements are analyzed on hardware items, specific electronic components, are selected and implemented into the block design of the DMM hardware. Based on the block design of hardware, the hardware of the DMM subsystem is designed, selectively simulated and implemented along with the printed circuit board. On the implemented hardware of the DMM subsystems measurements are performed in order to verify the basic functionality of the hardware and the calculated, assimilated and measured values are compared as well. At the end of the thesis there is a short description of the implementation of the software design and its use for basic initialization of the selected processor, together with the verification of its basic function - measuring the frequency of the internal clock sources and the clock domains. The work is completed by sending a message of defined parameters to the selected communication line and sapling it by an oscilloscope, so that the basic function of the DMM subsystem is verified.

Design of flight test laboratory for ballistic recovery systems testing
Chadima, Bedřich ; Pejchar, Jan (referee) ; Popela, Robert (advisor)
This thesis is focussed on designing of the air drop labradory for testing the balistic recovery systems. The first part of the thesis describes balistic recovery systems, their parts as well as methods of testing this devices. In the second charter there is a description of older vision of a testing device and simple test with the electronics of the testing device. The next step is designing of the new koncept of testing device and the structure analysis of the frame. The product of the thesis is a modular automated testing device, which is able to test balistic recovery systems for aicrafts with the weights between 230 and 1700 kilograms.

Telemetric wireless tire temperature module
Halgoš, Matúš ; Fiedler, Petr (referee) ; Benešl, Tomáš (advisor)
This work dedicates wireless telemetry, specifically one part, which is the measurement of tire temperature. In the individual chapters, giving the reader the reasons who and under what circumstances can benefit from this information introduces the reader to the ways in which the temperature can be measured, processed and sent. In the following chapters, the reader will be introduced to the selection of components used in the design. And the last part deals with the design of hardware and software of the battery-powered module for measuring the temperature of tires, which is part of the datalogger, which collects vehicle driving data.
