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.

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.
