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.
Solving of Security Problems in Local Networks
Marek, Martin ; Heriban, Pavel (referee) ; Roupec, Jan (advisor)
The diploma thesis is concerned with solving security problems in local computer networks. The main part deals with the solution of authorization of wireless clients against the RADIUS server and with the proposal of domain controller using open-source products and the tools of operating system GNU/Linux.
Evaluation of the Wi-Fi technique for use in a navigated orthopedic surgery
Truhlář, Jindřich ; Sekora, Jiří (referee) ; Provazník, Ivo (advisor)
Following text focuses on use of wireless technologies in OrthoPilot navigation system developed by B.Braun company. Description of OrthoPilot software is followed by overview of available wireless technologies highlighting their both advantages and disadvantages. Practical part consists of two main parts, mostly dealing with electronic circuits. First part describes development process of camera-wireless printed circuit board which substitutes currently used RS-422 cable connection between PC and stereo camera. Part of this chapter covers programming in C++ in order to make interface compatible with the rest of current OrthoPilot software. Second bigger part deals with remote controller development using prototyping board mikroMedia for XMEGA. Besides electrical circuits design, chapter describes also software part - microcontroller programming in C language. Thesis is concluded by discussing system limitations and ideas for future development.
Wireless sensor network
Šťáva, Radek ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The main theme of this work is to design and make a modern network of wireless sensors, when the main used circuit in the sensor module and the receiver module is microcontroller Texas Instruments CC430F513x. Care is taken primarily at very low power of sensor module for long battery life when on battery power. It is also emphasis is on reliability involvement of miniature size, expandability and high precision modules of basic sensors.
Application for Controll System in Caravan
Řehulka, Marek ; Novotný, Tomáš (referee) ; Kořenek, Jan (advisor)
This Master's thesis deals with the development of a mobile application for a control of the supervisory system in caravans and motorhomes. The thesis presents the currently available principles and research of the existing solutions. This custom solution includes an Android application and a desktop application of the central unit simulator of the supervisory system. The simulator is based on the Node.js and node-webkit technologies. The simulator communicates with the devices available via RF Transciever and it simulates other devices. The mobile application communicates with the simulator via Bluetooth Low Energy and GSM. Major part of the implementation description is devoted to the Bluetooth Low Energy technology and to issues, which are associated with it. The resulting solution puts emphasis on the usability of the user interface and the ability to supervise a wide range of connected devices. The system also implements custom logic alerts for tracked events. The thesis concludes with evaluation of the resulting system and outlining the future development options.
Wireless Signal Transmission of DMX512 Interface
Polóni, Pavol ; Jaroš, Jiří (referee) ; Šimek, Václav (advisor)
Master's thesis deals with design and implementation of a system for wireless transmission of DMX signal 512, which is primarily designed for the management of lighting effects. Its electrical specification is based on the EIA485 standard. Text of the work describes the design stage. First is the issue of implied actual protocol DMX 512 or EIA485. Next sign on selecting a suitable architecture for wireless transmission, management and compilation of the block diagrams. Describes the operation of the component selection and circuit implementation of the scheme, which is using the DPS Eagle compiled. In conclusion, this work is to evaluate the results of the proposed system and showing the way to its further development so that it can be realistically implemented in practice.
Telepresence Autonomous Robot for Exploration of Unapproachable Areas
Krkavec, Martin ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The subject of this master's thesis was to get familiar with a robot developed at the Department of Intelligent Systems of FIT VUT Brno. The goal of this work was to design and then implement hardware and software improvements of the robot so it could be capable of telepresence exploration of a narrow cave using remote control, including autonomous return back to the entrance. Also suggest possible extensions for a further improvement of the robot.
Java Sun SPOT sensor nodes
Malina, Karel ; Komosný, Dan (referee) ; Holešinský, Pavel (advisor)
This thesis deals with the use of Java Sun SPOT sensor nodes for multipoint wireless temperature monitoring and regulation through these nodes. The theoretical part is the description, composition and operation of sensor nodes Sun Spot Java. In the practical part there are description of programmed applications in the NetBeans IDE for a wireless temperature monitoring, battery capacity and their views on a host computer in the form of a graph. In the second part of the practical section is described how temperature can be regulated using Sun SPOT nodes.
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.
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.
