Design of electronic subsystem for reduced gravity impact simulator
Ostrý, Lubomír ; Hadaš, Zdeněk (referee) ; Věchet, Stanislav (advisor)
The focus of this thesis is development of an electronic subsystem for reduced gravity impact simulator. The research part of this thesis firstly covers methods used for simulation of microgravity or reduced gravity and compares them. Another part of research focuses on three selected potential approaches to creating the electronic subsystem for this device. The second, practical, part of this thesis describes the design and development of the electronic subsystem. The foundation of the electronic subsystem is a control unit which has been developed on the basis of an STMicroelectronics microcontroller. Using the control unit, the electronic subsystem measures pressure, position, acceleration and force in the system. Another task of the control unit is control of a stepper motor. Integration of individual elements into the electronic subsystem is described both in terms of software and hardware. Furthermore, a graphic user interface program for PC has been developed as a means to interact with the system. In the final part of the thesis, the operation of the electronic subsystem is described and lastly, the electronic subsystem is evaluated.

Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

Autonomous RC ship model
Jevická, Barbora ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This Master’s thesis deals with working on development kit, which is used for RC ship model. The basis are programmable Nucleo STM32 microcontrollers, to which other used modules are connected. The goal is to test each component and create system for navigation of the ship and wireless communication between controller and ship. GPS module and compass are used to navigate and determine the direction of the ship. Controller and ship can communicate through bidirectional wireless modules with antenna. The RC ship model can be switched between manual and autonomous modes. The main result of this thesis is autonomous movement of the ship on to a predetermined GPS coordinates and parallel communication with the user.

LoRa Gateway
Očenášek, Matěj ; Janůš, Tomáš (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the implementation of two LoRaWAN systems and the creation of instructions on how to put these systems into operation. Both systems consist of a end device, an access gateway, a network and application server, and a website to display the data obtained from the end device. The public network "The Things Network" and the local network ChirpStack are used to implement these two systems.

Receiving RTTY decoder
Šuňal, Štefan ; Caha, Tomáš (referee) ; Lattenberg, Ivo (advisor)
This thesis deals with designing and implementing autonomous decoder for RTTY communication. Theoretical part of the thesis deals with researching the RTTY technology and FSK modulation, which it uses, focusing mainly on the methods of demodulation. Next part of the thesis compares suitability of available platforms. Practical part of the thesis describes the design and implementation of circuit board, firmware and computer application. The device is using STM32 microcontroller. Firmware was developed in C++ using Arduino. The computer application was created by using C\# and WPF. 3 methods of FSK demodulations were implmented. One is using a FFT algorithm. Other two calculate frequency based on the period of square signal.

Control and measurement unit for plasma generators
Paulovics, Petr ; Boušek, Jaroslav (referee) ; Zemánek, Miroslav (advisor)
The diploma thesis deals with the issue of plasma generators. Specificantlly, the work focuses on the design of HMI devices for plasma generators, including the design of the control part of the generator. The main advantage of controlling the plasma generator using an HMI device is the ability to quickly change important parameters. The HMI device allows convenient switching of the generator output frequency without the need to interfere with the wiring, which leads to higher efficiency when working with the plasma generator. Another advantage of the HMI device is the display of all important information on the LCD display. The work deals with the basic theory of plasma and its use, the division of microcontrollers and the description of their peripherals, the selection of components used and their wiring. The last part of the work is devoted to the software of the plasma generator.
