Design of the on-board system for a motorcycle
Ševčík, Jan ; Benešl, Lukáš (referee) ; Juráň, Radovan (advisor)
This work deals with the design and construction of an on-board computer for a vintage Jawa motorcycle. The design combines measuring sensors of our own design and those commonly available on the market, a main control board of our own design and assembly without interfering with the structure of the motorcycle. The system is considered for mounting on the Jawa 250/592 motorcycle, with some parts from other motorcycles, allowing for easier fitting. ESP32 from Espresiff is used as a microcontroller, which is placed in the tank of the motorcycle and displays the measured data on the LCD display. The system also allows you to control the entire motorcycle, such as enabling starting or turning on the lights

Low-code / No-code rule based engine for positioning data
Vychodilová, Natálie ; Bohačík, Antonín (referee) ; Juráň, Radovan (advisor)
This thesis is focused on the design and implementation of a software system intended to eliminate programming needs for selected process problems. This system allows the user to create rules over positional data. It addresses design of the server and client parts of the application, design of the database and user interface. The design of the web application is based on knowledge of UWB technology and RTLS systems.

Smart hydroponic system
Seč, Filip ; Juráň, Radovan (referee) ; Benešl, Lukáš (advisor)
This bachelor thesis focuses on the implementation of a smart hydroponic system with the capability of remote control and monitoring via a web interface. The main objective of the work is to design and implement hardware and software components for this system. Within the scope of the work, it is important to familiarize oneself with the issues of hydroponics and explore various types of hydroponic systems and their usage. Focus will also be given to the analysis of the advantages and disadvantages of individual types of hydroponics. The next step involves getting acquainted with microcontrollers and sensors that will be used within the hydroponic system. Based on this, we will design a schematic connection and a printed circuit board (PCB) for the system. After designing the hardware, the implementation follows, along with bringing the de- signed modules to life. At this stage, it is necessary to program the individual modules so that they are able to communicate and process data. An important step is the design of communication with the web interface, which will enable data reading and system control. In this way, it will be possible to monitor the hydroponic system remotely. At the conclusion of the work, we verify the overall functionality of the system and compare it with existing commercial solutions available on the marke

Secured transfer of digital messages
Horký, Matyáš ; Juráň, Radovan (referee) ; Tomašov, Adrián (advisor)
Diplomová práce zkoumá alternativní přístup k e-mailu. Ten, i když je nejběžnější a univerzální způsob komunikace přes internet s téměř kýmkoliv online, ať jde o soukromou osobu nebo organizaci, trpí technickými i praktickými problémy, jakými jsou například absence soukromí nebo spolehlivosti. Práce hodnotí ekosystém e-mailu, spolu s aktuálním stavem kryptografie, a navrhuje nový protokol a datový formát který by mohl být použit téměř transparentně. Protokol je postavený nad mTLS a PKI; definuje konkrétní zprávy které mohou být použity k dohodnutí přenosu dat mezi klienty a servery. Datový formát je vlastní lineárně čitelný binární formát, strukturovaný způsobem hlavička–délka–data. Výsledek je vyhodnocen jeho přínosy a nevýhodami, spolu s obecným zamyšlením o důležitosti a místu e-mailu v současném internetu.

Measuring Station Firmware for LoRaWAN Wireless Data Collecting
Janos, V. ; Juran, R.
This paper describes the software side of the outdoor carbon dioxide flux low-power measuring station prototype. In the following lines, the selected chamber measuring method is described as well as the IoT protocol LoRaWAN, which is used in this project. The principle of measuring software and following data processing is also introduced. Controlled parts are thermometer, CO2 sensor, and chamber fan. The device is intended to be used in places that have natural sources of carbon dioxide. Measured data are sent through the LoRaWAN network for visualization and further evaluation.

Experimental Platform for Sensor Fusion Positioning Methods Evaluation
Juran, Radovan
Position and context awareness is becoming greater in importance as one of the key enablers of the Industry 4.0 concept, with impact on analysis and optimizing production processes, their direct control, increasing and ensuring the safety of personnel and technology, as well as enabling traceability of products. There are many approaches to achieve a real-time location system (RTLS) capable of providing positioning data, yet each approach usually has its limits given by the physical principles of technology which it is primarily based on; mostly a wireless signal transmission where the performance boundaries lay in non-line-of-sight (nLoS) scenarios. Current literature already presents various approaches capable of dealing with these shortcomings and presents various combinations of sensors based on different phenomena, the drawbacks of which are mutually compensated, known as sensor fusion. This work presents practical design of a compact platform, which utilizes Ultra-WideBand (UWB) as one of the predominant wireless technologies for wireless positioning with with IEEE 802.15.4z compliant radio integrated circuits in cooperation with a 9-axis absolute orientation sensor, expandable with add-on boards.

Measuring station firmware for wireless data collection via LoRaWAN
Jánoš, Vít ; Možný, Radek (referee) ; Juráň, Radovan (advisor)
This thesis deals with software development for STM32WL55-JC1 MCU. Development kit was chosen primarily bacause of its LPWAN possibilities. Final prototype communicates on LoRaWAN network. Data are sent through public network from The Things Network, these data are concentrations of carbon dioxide, temperatures and carbon dioxide flux. Data are also backed up locally on SD card along with timestamp. The software was designed with the use of the chamber measurement method in mind, which is also described in the text.

Intelligent wattmeter with network communication options (Ethernet / WiFi)
Haluška, Daniel ; Juráň, Radovan (referee) ; Rusz, Martin (advisor)
The goal of the Bachelor Thesis is the implementation of a measuring device for measuring alternating voltage, current and calculating of power consumption. A voltage divider with one-way offset is used for voltage measurement, and the ACS712 integrated circuit with a Hall sensor provides electric current measurement. The Arduino singleboard computer, for which the OLED display is suitable, takes care of the representation and calculation of the electrical power. Furthermore, this device allows communication with the Internet and through the server allows a simple graphical display of measured data. The manufactured measuring device allows measuring power regular outlet up to 3680 W.
