DMX 512 protocol analyzer for personal computer
Brouček, Vilém ; Juráň, Radovan (referee) ; Krajsa, Ondřej (advisor)
This bachelor thesis consists of designing and assembling an USB–DMX512 analyzer. It contains detailed information about the protocol itself, particularly the structure of the signal and its physical layer. It discusses options for analyzing the signal, chooses an appropriate microcontroller unit and provides a draft of a hardware for the controler. The thesis describes the assembled analyzer, explains its functions, the selection of components, and the principles of PCB design. It also explains the usage of the device and its potential future upgrades. The thesis provides a description of the code for the STM32 microcontroller and the custom-made libraries used for the DMX512 packet analysis and creation. It then familiarizes the reader with the code of the personal computer application, the reasons for choosing C# as the main programming language, and explains the structure of the object-oriented code, along with the custom-made libraries for DMX512 packet generation and analysis of the received data. The result of the thesis is a working DMX512 analyzer, which can receive and transmit the signal, display transmitted data, and connect to a PC via the developed software.

LoraWAN gateway for sensor network
Rehberger, Marek ; Juráň, Radovan (referee) ; Krajsa, Ondřej (advisor)
The master thesis deals with the design and implementation of a communication gateway for IoT technology, specifically LoRa / LoraWAN technology. In the practical part, the circuit diagram was developed and the circuit board was constructed in the Fusion360 program, and the software part was created for communication and data collection between the sensor part and the MQTT server.

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.

Implementation of IoT communication technologies in NS-3 simulation tool
Rehberger, Marek ; Mašek, Pavel (referee) ; Juráň, Radovan (advisor)
The bachelor thesis deals in its theoretical part with LPWA communication technologies in the licensed frequency spectrum, specific technologies LTE Cat-M1 and NB-IoT. The theoretical part summarizes the terms concerning to LPWAN (Low Power Wide Area Network), licensed and unlicensed technologies, SmartGrids, NB-IoT and LTE Cat-M1. The use of LPWA technologies in the field of SmartGrids is described and the idea of Smart Metering in buildings is used in the work. Subsequently, in the practical part for the LTE Cat-M1 technology, the implementation of communication scenarios for data transmission within SmartGrids is performed using the tools Network Simulator 3 (NS-3) and the LENA module. The results of the simulations are clearly processed in the form of graphs and tables.

Field sensor network for microclimatological measurements
Juráň, Radovan ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
Tato práce je zaměřena na návrh terénní bezdrátové senzorové sítě pro mikroklimatologická měření, zejména výronů juvenilního oxidu uhličitho v oblasti hydrotermílního krasu, založené na LoRaWAN. V teoretické části práce je předložen přehled cílové oblasti, možností řešení měření, získávání a přenosu dat. Praktická část se pak věnuje kompletnímu návrhu celého systému, to znamená od měřicího zařízení přes koncentrátor a gateway až po backend odesílání dat do cloudového úložiště. Výsledky tohoto komplexního problému jsou prezentovány průběžně a přílohy obsahují detailnější a názornější ukázky.

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.

Rule-based Engine for Position Data: Low-code/No-code Approach to Process Logic
Vychodilova, Natalie ; Juran, Radovan
Real-time location systems (RTLS) are becoming astandard part of modern digitized industrial facilities, enablingacquistition of position data of objects or people tracked in agiven monitored area. These systems can utilize the virtualizedcoordinates to divide the real space into user-defined digital zonesand give them meaning within a process. This paper describesthe design and implementation of a commercial RTLS systemextension, intended to eliminate the need for programming anycomplex position data processing by leveraging Low-code/Nocodeapproach to creating process logic in a user friendly way.

Back to the Future: Developing an On-Board System for a Vintage Motorcycle
Sevcik, Jan ; Juran, Radovan
This paper describes complex design of a prototypeof an on-board system for older motorcycle for measuring itsoperational characteristics. The birth of the idea is described,followed by explanation of characteristics measured by thesystem, principles of their measurement, and processing the datafor visualization on a display. The system is designed with theaim of the most minimal intervention into the construction ofthe motorcycle, but being easy to reproduce and durable enoughfor a real deployment and use while riding the motorcycle.
