Efficient use of renewable energy sources in a residential building
Burčo, Matúš ; Paluřík, Pavel (referee) ; Jablončík, Lukáš (advisor)
The thesis focuses on the design and implementation of an optimization algorithm for an energy management system in apartment buildings. The thesis analyzes current technological solutions for smart home energy management, including open-source and commercial systems. It further considers the use of containerization technologies for the implementation of the algorithm in practice. The second chapter focuses on renewable energy sources such as solar, wind and hydro power and discusses methods for their efficient integration into energy systems. The third chapter describes specific system elements, such as photovoltaic panels and battery storage, in the context of a residential building. The fourth chapter describes the development of the optimization algorithm, its testing and integration with data collection and visualization platforms. The aim of the thesis is to show how the system can be used to make efficient use of the available energy resources and thus reduce the energy costs of the building.

Optimising the use of renewable energy sources by controlling home technologies
Bolf, Marek ; Mikulášek, Michal (referee) ; Jablončík, Lukáš (advisor)
Initially, this thesis is devoted to the analysis of methods of efficient energy management and the analysis of renewable energy sources. Subsequently, the thesis focuses on detailing the design of an optimization algorithm that schedules and distributes the flow of electricity in the home. The effectiveness of the algorithm has been computationally demonstrated using data collected from days in the past. This algorithm is also aimed at communicating with other devices in the home. In this paper, the algorithm is explained verbally, with diagram and calculations. Subsequently, the type of control unit has been selected.

Linux distribution for smart building gateway
Nagy, Tomáš ; Komosný, Dan (referee) ; Jablončík, Lukáš (advisor)
The goal of the thesis was to create a Linux distribution for a smart home gateway. The thesis is divided into theoretical and practical parts. The theoretical part dealt with the analysis of the Linux operating system. Subsequently, single board computers are described and compared. In the next part, the gateway issues, communication protocol selection and application containerization are discussed. As a result of addressing the issue, a procedure for adding tools for home automation, the construction of scripts that automate this issue and instructions for their proper execution were proposed.

The control unit of the door systems for public transport
Jablončík, Lukáš ; Vlachová Hutová, Eliška (referee) ; Friedl, Martin (advisor)
The topic of my bachelor´s thesis is to design a control unit of the door systems for public transport. The control unit is designed by using modern components. Their availability should be not less then ten years. The unit is controlled by a microcontroller ATMEGA and the motor is switched using the h-bridge. The control unit has ten programmable inputs and two switching outputs. PCB design is optimized for mass production. The result is a functional prototype of control unit.

Solar pool heater
Jablončík, Lukáš ; Chladil, Ladislav (referee) ; Šteffan, Pavel (advisor)
The master´s thesis deals with the design of the solar heating regulator of the swimming pool. The basis was to study the available solutions for the solar pool controllers, to define the requirements, to design the concept and the block diagram of the own thermostat. The thesis also provides a description of several for the Internet of Things. The most suitable is used to control the thermostat. The resulting thermostat regulates two power outputs for filtration and the pump, it can be set using the keyboard and graphic display. At the end of the work is practically verified functionality on the model and on the real pool with solar heating.

Communication protocols emulator
Fabulec, Martin ; Dejdar, Petr (referee) ; Jablončík, Lukáš (advisor)
The content of this work is the analysis of commonly used serial protocols RS-232 and RS-485 and their transmission using the optical fiber. The work deals with the analysis of the actual problematic and the connection design of the optical fiber system, communication through optical fiber and communication interface. The design of the communication protocol emulator and the verification of the functionality of the transmission system are also discussed. The theoretical part deals with optical components such as optical receiver and transmitter, SFP module and the description of the RS-232 and RS-485 interface. The practical part mentions the connection proposal and subsequent data transfer.

Error correction methods in optical transmission system
Burčo, Matúš ; Ružička, Michal (referee) ; Jablončík, Lukáš (advisor)
The bachelor thesis deals with a design of an optical transmitter system and subsequent detection methods and errors correction that occured during the process. A part of the thesis is making an acquaintance with transmission parameters in optical fiber, such as transmission rate, attenuation, dispersion and bandwith. Hamming’s and Reed-Solomon’s correction codes are described in detail, wich are then used for error correction in the proposed optical transmitter system. A program is designed for Hamming’s code that is able to detect and correct occurred error in transmision. The thesis also includes measurement of attenuation on the optical path using various transmitters, recievers and optical fibers.

Reduction of CentOS operating system
Kluka, Peter Milan ; Jablončík, Lukáš (referee) ; Komosný, Dan (advisor)
Táto práca slúži ako podporný materiál pre predmet Sieťové operačné systémy a ako pomocný materiál pre realizáciu projektu v rámci tohto predmetu. Účelom tejto práce bolo vykonať redukciu operačného systému z hľadiska jeho veľkosti na disku. Zadaným operačným systémom bola Linuxová distribúcia CentOS Stream 8. Redukovaný operačný systém obsahuje grafický web prehliadač, PDF prehliadač dokumentov a je dostupný pomocou vzdialeného pripojenia SSH. Práca porovnáva veľkosti odporúčaných grafických rozhraní a aplikácií. Na základe analýzy bola vytvorená sada skriptov, ktorá zautomatizovala proces minimalizácie. Výsledná veľkosť redukovaného systému bola 678 MB.
