System for Autonomous Data Collection from Weighting Sensors
Lučanský, Adam ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
Cílem bakalářske práce je navrhnout a vytvořit potřebnou elektroniku s plastovým pouzdrem, webovým rozhranim pro nízkonákladové bezdrátové měření váhy včelích úlu. Sledovaním váhy úlu je možné dlohodobě sledovat zdraví včelstva. V první časti práce je vysvětlen obecný koncept měření váhy, potřebná elektronika a způsob bezdrátové komunikace. Následně je detailně popsán předložený návrh včetně firmwaru. V závěru se pojednáva o dosažených výsledcích práce a možnosti vylepšení. První vyrobena jednotka je darována lokálnimu včelaři.
Smart Home Control
Fučík, Jan ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis summarizes the subject of intelligent homes and describes commonly used standards and commercial solutions on the market. The thesis covers the design of a low-cost and easy to use smart home system which can be managed over the internet, uses a genetic algorithm for heating regulation optimization and its central computing unit is a low-cost, embedded device with low power consumption. The functionality of the system is verified on a practical application of heating regulation in a house. The efficacy of the system for energy savings is shown; it is based on measured data statistics.
Smart Home Equipment
Fučík, Jan ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
This thesis summarizes the subject of intelligent homes and describes some commercial solutions on the market. The thesis covers the design of a simple open, low-cost and easy to use system and also describes the implementation of a pilot system, which uses microcontrollers and wireless data transfer between sensors, actuators and a controller which can be managed over the internet. A possible extension of the system for practical use is also stated in the thesis.
Automated Control and Monitoring of Central Heating for Older Buildings
Mužila, Matej ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The purpose of this thesis is a design of an automated heating regulation system for an old building. The thesis consists of a system architecture design, an implementation of the system, including prototype manufacturing of the required devices, and testing of the whole system in practice, with focus on functionality and efficiency. Several hardware devices were designed and manufactured, for which appropriate controlling software was implemented. The implemented software architecture enables users to control the system using a graphical user interface, and allows for an easy extension of the system. The graphical user interface, which is accessible both locally through a touchscreen and remotely using a web application, enables users to easily configure connected devices and regulated zones, and to set temperature level in the defined zones variably depending on a week day and time. The user interface also provides statistics about the heating system. The implemented automated heating regulation system was successfully tested in real conditions of a flat in a historical building. The system can be extended both hardware-wise and software-wise.
Platform For Collecting User Identifiers On Ieee 802.11 Wireless Networks
Ilgner, Petr
At the present time the widely usedWi-Fi networks provide comfort by zero configuration settings. However it leads to serious privacy issues. The article is focused on user information which can be extracted from service communication. The article presents several ways how to collect these information and introduces the platform for collecting user data. In the first part there is described the available network discovery mechanism followed by section about designed methods for obtaining user information. The last part describes the implemented platform in detail.
Modelling and simulation of communication system receiver for unmanned aircraft
Hoferek, Jakub ; Prokeš, Aleš (referee) ; Maršálek, Roman (advisor)
This diploma thesis deals with the simulation of the radio communication system for satellite control of unmanned aircraft, namely the command and control communication link – the forward link. The aim of the thesis is to create a simulator in the Matlab environment. The simulator includes a model of the transmitter, radio channel and receiver. Four-state CPM modulation with partial response and filtered symbol shape is used. The radio channel performs noise, frequency Doppler shift and time delay to the received signal. Subsequently, in the Acquisition Unit, the Doppler shift and time delay are detected and compensated. At the end of the thesis, the simulation results of the presented model are presented in the form of graphs đť¸s/đť‘0.
Universal communication unit
Ružička, Michal ; Mlýnek, Petr (referee) ; Sláčik, Ján (advisor)
This bachelor thesis is going to deal with communication over the power network. Aim of this project is to clarify this issue and consequently to use the acquired knowledge for desingning own communication unit. The basic parameters of power network which influence this type of communication are being described in this thesis. The concept of universal communication unit is created. Pheripheral solutions are chosen for this concept and the given device will be made of them. The custom communication unit is created on this basis. The funkcionality of this unit is tested in the work.
Sport robot
Slovák, Tomáš ; Šteffan, Pavel (referee) ; Háze, Jiří (advisor)
This bachelor thesis is focused on design and manufacture of two legged walking robot, that has 3D printed parts and is battery powered with the option to be remotely controlled.
Phishing and other risks of public Wi-Fi networks
Mäsiar, Daniel ; Luc, Ladislav (advisor) ; Sedláček, Jiří (referee)
This bachelor's thesis deals with problematics of public wireless networks, with focus on tho-se operating in densely populated areas such as public transport, libraries or fast-food restau-rants. The goal of this thesis is to evaluate how users of public Wi-Fi networks behave, what their customs are and how high is their awareness about possible threats. In the intro of the theoretical part of this paper, main standards and norms are listed, essential terms are defined and various types of possible wireless attacks are presented as well as briefly described. Further, this thesis inspects possible ways of protection against these attacks and finally, term phishing is concisely defined. The empirical part is dedicated to creating of a suitable tool for gathering statistical data about awareness of users at public places. Further, this tool is used in combination with phishing methodics for the actual statistical research. The whole process will follow the rules and laws defined by The Office for Personal Data in Czech Republic.
Nikola Tesla - Genius, who changed the World
Fexová, Lucie ; Beneš, Zdeněk (advisor) ; Čechura, Jaroslav (referee)
Nikola Tesla - Genius who changed the world This bachelor thesis tells the story of life and work of Serbian inventor Nikola Tesla and it's mainly dedicated to years, which he spent in America. In the context of that time it highlights the importance of his inventions, some of which have significantly affected today's technology. The largest part of the work, occupy two Tesla's long life disputes which affected his career and personal life. The first one of these, "war of currents", was between Tesla and Edison. The second one between Tesla and Marconi passed because of invention of radio. The development of both disputes is described from the historical, economical and technological side, which focuses on the consequences for today's world. At the end of the text, there is a brief presentation of lesser-known Tesla's inventions and various recognitions which he received for his contribution to science.
