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.

Wireless Sensory Network Using LoRa Technology
Mikulášek, Michal ; Pokorný, Jiří (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis focuses in the first half on the Internet of Things and the available wireless technologies for the Internet of Things. Each technology is characterized by its features, pros and cons, as well as the possibilities of using it in the Internet of Things. In the second half of the thesis, a practical design and construction of a LoRa network, consisting of a sensory and a central unit, is carried out. The parts of the solution are designed wiring schemes, printed circuit boards and detailed photo documentation. Additionaly the software solutions for both types of units are described, with detailed descriptions of the proposed features. The maximum possible range is tested and documented for the entire solution. Subsequently, a detailed measurement of the power consumption of the sensor unit is carried out and an extensive estimation of its battery life for a selected battery.

Design of a current data logger for LPWA sensors
Mikulášek, Michal ; Možný, Radek (referee) ; Štůsek, Martin (advisor)
This Master thesis deals with the design and construction of a measuring device for measuring and the current consumption logging of sensors using LPWAN (Low Power Wide Area Network) technology. The theoretical part of the thesis firstly summarizes selected LPWAN technologies. Selected technologies, namely: LoRaWAN, Sigfox and Narrowband IoT (NB-IoT), are described more in detail. Further, the current measurement techniques are briefly discussed. The main focus is given to the current shunt measuring methods. The second half of thesis describes procedures conducted during the design and construction of a measuring device. The current measuring is based on the current shunt circuit complemented by the voltage amplification circuit, whose output is subsquently converted into digital form using an AD converter. The thesis describes in great detail the procedures for selecting individual components and important processes used in design of printed circuit boards. An integral part of the measuring device implementation is the design and implementation of control software, which is described in detail and supplemented by workflow charts underlining the entire description. The implementation of the entire measuring device is completed by the design and implementation of the cover box using 3D printing technology. Finally, the specifications of designed device are briefly discussed based on the limits of the used components.

EV charging station control and management utilizing LPWA technologies.
Mačina, Martin ; Mikulášek, Michal (referee) ; Dvořák, Radim (advisor)
The bachelor thesis deals with the transmission of OCPP (Open Charge Point) protocol using LPWA (Low -- Power Wide Area technology). At the beginning of the theoretical part is described the OCPP protocol, where the emphasis is put on the security of the protocol. Next, the LPWA technologies and their parameters are described. In the practical part, the communication between the OCPP client and the OCPP server was introduced and the key elements are described mediating this communication. It further discusses the completion of the implementation of the OCPP protocol in Python and the completion of the measurement using the BG77 module. The practical part results in a completed measurement using the LPWA module on the sites that are shown on the generated map. The result of the work is a description of the measured values and an evaluation of the use of LPWA technology for OCPP protocol transmission.

Research of Algorithms for Improvement of Rainfall Calculation Based on Crossing of Microwave Links
Vomočil, Radek ; Mikulášek, Michal (referee) ; Bubniak, Milan (advisor)
Even in modern times, the exact rainfall calculation is an area containing a number of challenges. Although it may seem that the combined technologies for rainfall estimation are sufficiently accurate, in recent years there have been opportunities to further complement and refine the rainfall estimation through so-called opportunistic methods. This work deals with the creation of a new algorithm for the distribution of rainfall intensity within the framework of rainfall measurement through a network of microwave links. The theoretical part of the work deals with the possible ways in which the algorithm can be created and in what ways the calculation of rainfall can be approached. The practical part first deals with the creation of an algorithm for the linear distribution of rainfall intensity in 2D space along the route of the microwave link, based on the input parameter of the interval length. This is followed by the creation and implementation of an algorithm for the distribution of rainfall intensity based on the crossing of microwave links.

IT infrastructure monitoring system using robotic process automation
Valíček, Matěj ; Mikulášek, Michal (referee) ; Sikora, Marek (advisor)
The goal of this bachelor’s thesis was to create a tool for categorizing elektronic mail using Robotic Process Automation (RPA). The categorization is based on a message with category „_TEMPLATE“ and the similarity of its subject with the subject of the incoming message. The robot further analyzes the punctuality of the messages and in case of delay, the administrator is notified about the situation. Finally, messages are moved to the archive folders so that only one message from each subject remains in the main folder at any time.
