Implementation of IoT Communication Protocols Utilizing UniPi Module for Raspberry Pi
Krejčí, Jan ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
Presented diploma thesis is focused on the implementation of Wireless M-Bus protocol to embedded device RaspberryPi with expansion board UniPi. The protocol is implemented in Python with Wireless M-Bus devices communicating via IQRF transceiver connected to the UART bus. The theoretical part is focused on an overview of embedded devices for the IoT, the possibility of their expansion. Further, the UniPi expansion board and Wireless M-Bus transceiver are detailed. First part of the thesis focuses on the Wireless M-bus layers, which provides a basic knowledge for understanding the practical part. The theoretical part concludes overview of captured devices including a description of their data units. In the practical part is the implementation of the sample application for receriving data from a Wireless M-Bus sensors. The application is able to read data from devices transmitting encrypted communication.

Design systems used in the field of electrical apparatuses
Stejskal, Jiří ; Krejčí, Jan (referee) ; Valenta, Jiří (advisor)
Bachelor´s thesis is engaged on the base of submitter´s requests company OEZ, s.r.o. and is divided into two parts. The first part of work deals with the most often used 2D CAD systems that are used by designers according to their answers in the area of suggestion of electric switchboards low voltage. In the work are described main possibilities of these systems, then what kinds of data format are supported by them. In the second part of the work are described programs established on calculation of warming switchboards. It goes about programs, which supply concrete producer of switchboard case, and further programs based on method of final elements and method of final volume, which enable graphic representation of results.
Mobile Application "Paramedic doggy" - Unexpected Event
Krejčí, Jan ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
The aim of this thesis is to design and implement a simple educational mobile application for children which, in the form of a game, shows how to proceed in a model emergency situation (train accident). Firstly, the thesis describes general principles of providing first aid in an emergency situation as well as its training. Secondly, the thesis clarifies characteristic features of educational digital games, analyses already existing solutions and describes Unity game engine. Based on information acquired so far, the educational game is designed and implemented in Unity. The method and the results of the testing are presented in the conclusion. The final version of the game is ready for publishing.
Optimization of the ground network infrastructure of radio navigation aids for RNAV in FIR Praha
Krejčí, Jan ; Vosecký, Slavomír (referee) ; Ptáček, Pavel (advisor)
This diploma thesis concerns with creating of study which deals with the optimization of the ground network infrastructure of radio navigation aids for RNAV in FIR Praha. The thesis contains an analysis of concept of development of Czech navigation environment and introduces DEMETER software, in which the optimization analyses are realized. The thesis describes DME/DME navigation system from the perspective of individual components and parameters. The actual study deals with an optimization of the ground network infrastructure of the radio navigation aids and includes the definition of network performance requirements, creation of general methodology of optimization of navigation performance analysis and a procedure of choosing a suitable placement of radio navigation aid. The integral parts of the study are analyses of current state of navigation performance and analyses of possible improvement of radio navigation infrastructure.
Milling machine CNC control
Krejčí, Jan ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine, 3D model of that and eventual control using PLC. All axes are powered by stepper motors, with encoders, connected to control cards and industrial computer from company Beckhoff. For this control is made full switchboard, supplemented by electrical wiring diagram. Program control along with visualization is made in software TwinCAT 3. Drill-mill machine can be controlled manually or automatically by program.
Retrofit of milling machine
Krejčí, Jan ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine and control using PLC. All axes are powered by stepper motors connected to special control cards and industrial computer from company Beckhoff. For this control is made full switchboard. Programmed control is done in software TwinCAT 3. In the program is done manual and automatic control together with their visualizations.
Centre for Prevention, Masaryk Oncology Institute in Brno
Krejčí, Johana ; Adamson,, Krsitina Richter (referee) ; Sládeček, Svatopluk (advisor)
Diplomová práce zpracovává komplexní návrh nového Centra prevence rakoviny v areálu Masarykova onkologického ústavu na Žlutém kopci v Brně. První stavba svého druhu v České republice doplňuje současnou zástavbu nemocničního areálu. Koncepce navrženého souboru budov se zaměřuje na kontakt hranice nemocničního areálu s nově vznikající obytnou čtvrtí v této lokalitě. Návrh obsahuje jak samotné centrum prevence, lůžkové oddělení nebo protonové centrum, tak pronajímatelné prostory pro další služby široké veřejnosti.
Transistor tester connectable via USB
Skopalík, Daniel ; Krejčí, Jan (referee) ; Lattenberg, Ivo (advisor)
This thesis describe development and realization of transistor tester based on AtMega microcontroller. Developed equipment should be used by DIY users or students in university workshop to verify transistor functionality and measure basic characteristics. Equipment should be easily manufacturable in a piece quantity with reasonable costs.
Laboratory demonstrator for vibrodiagnostics
Blecha, Martin ; Krejčí, Jakub (referee) ; Klusáček, Stanislav (advisor)
This thesis deals with a vibration diagnostics of objects, structures and machines. The theoretical part is divided into three chapters according to type of the measurement. The first part called Modal Analysis discusses the basis of vibration, methods of measurement, relevant technical equipment and principle of experimental modal analysis. The second and third chapters of the thesis are focused on the diagnosis of defects. Each chapter mentioned above describes diagnosed defects, used methods and procedure for the diagnosis. Another part of the thesis summarizes practical issues and results gained in the laboratory experiments. It begins with discovering parameters of the measured object using technical diagnostics – experimental modal analysis. In the next step the hardware concept design was created, including custom measuring application programmed in LabVIEW. One part of the design is the laboratory model which includes a structure for free mounting and a possibility of excitation by an electrodynamic exciter. The application is also modified to enable measurements with shaker excitation. Finally, applications cooperating with professional software ModalVIEW and BK Connect were developed in order to simplify the operation and increase the comfort.
