Wireless meteostation
Holain, Martin ; Macháň, Ladislav (referee) ; Háze, Jiří (advisor)
The objective of this thesis is a design of the amateurish wireless weather station which is used to measure temperature, relative humidity, barometric pressure and velocity and direction of air flow. Part of this thesis also describes design of a device intended for display, processing and storage of actual measured data obtained from weather station.
Indoor optical wireless link design
Kaňa, Leoš ; Tošovský, Petr (referee) ; Hudcová, Lucie (advisor)
In last years phenomena of wireless communication technologies became a primary interest of big development laboratories whole world. Domain of point to point links which are realized by laser technology with narrow beam divergence and very sensitive photo-detectors is ordinarily used these days. This trend of using light waves as carrier medium turned interests of scientist to the sphere of wide area networks which is domain of wi-fi radio technologies. One of new trends in this sphere is also in-door free space optics. With expansion which leads to using LED's in everyday applications and with technological progress of last years, also grows tendency of most effective utilization of LED systems. The result of this effort is thought which considerate LED as source of artificial lighting and source of carrier medium for modulated signal. This kind of device must fulfill hygienic standards for illumination and also must be able to work with high frequency by which is signal modulated. These systems can provide links with sufficient capacity in order of hundred megabits.
Wireless thermostat
Králíček, Martin ; Viščor, Ivo (referee) ; Kincl, Zdeněk (advisor)
The Master’s thesis discusses wireless thermostat for a control boiler. In order to complete the project we have to design and realise the whole project with software design. The system contains two units, a master control and a measurement of regulation units. The project initially talks about regulation of heating systems for family houses and larger buildings like schools and stores for example. Next, the project describes the control and regulation units and their potential extension for effective and economical operation. Both units are equipped with microcontrollers, which these control each of function. The communication between both units is provided by wireless interface in free radio band ISM. There is a user interface for the master control unit’s regulation process. The measurement and regulation unit has only the possibility to switch between manual and automatic control for regulation of heating system.
Wrireless electronic timekeeping with big LED display
Frydrych, Michal ; Macháň, Ladislav (referee) ; Jaroš, David (advisor)
This thesis deals with the design and realization of wireless electronic timer for fire sport. The first part of thesis provides an analysis of the given problems and all component parts of the system which are needed for time measurement in the fire sport. The principal aim of thesis was to create a wireless electronic timer for simultaneous measurement of up to four lanes. The designed measuring system is equipped with a large LED display to show the final time. Targets and starting pistols are wirelessly connected with the main unit of timer with using a communication platform IQRF. The whole device is structural designed to the handling was as simple as possible.
Net for communication in a company
Sychra, Jakub ; Vaněk, Jiří (referee) ; Špinka, Jiří (advisor)
This work deals with accessible communications technologies and their possible usage in firms. It is necessary to have a survey about types and trends of communications technologies at proposal of communications network. It is important to choose the combination that is suitable with its reliability, achievement and price.
Four legged walking robot
Fischer, Jan ; Krištůfková Dvorská, Jolana (referee) ; Neužil, Tomáš (advisor)
The object of this thesis is an analysis of the possibilities of a wireless communication and a sensor‘s equipment for a four legged walking robot. The thesis is divided into three parts. In the first part there is a particular sale’s exploration in the section of the wireless communication modules. It refers to the differences among technologies in the methods of signal transmission, the technical parameters but also in the communication protocols. The next part of this thesis is focused on sensor’s equipment with the accent on the possibility of use for a four legged walking robot. It contains a short listing of sensors, which are available in the Czech Republic with division based on the type of sensing magnitude. These two parts make a base for the last part where I have chosen suitable communication modules along with sensors and realization wireless data transfer including control and visualization. The result of this thesis is the complete communication block from the user to the robot.
Four legged walking robot
Veleba, Tomáš ; Krištůfková Dvorská, Jolana (referee) ; Neužil, Tomáš (advisor)
The diploma paper deal with control problems of a four legged walking robot. They endeavour to establish and partly implement the walking and control algorithms. They are divided into six parts. Individual chassis types and their advantages and drawbacks are analysed in introduction. Next part describes mechanical design of the robot and also all realised electronics facilities. The third part describes in detail sensors that are used by the robot. Following part deals with description of robot's walking. It explains individual walking phases and analyses both static and dynamic stability. Next part contains description of the robot's software facility. The software facility of the control micro-controller and the algorithm that generates walking are explained in this part. It also describes software facility of control application in computer. Exploration of the possibilities for wireless control is carried out in the last part.
Vision system implementation on Bioloid robot
Ropog, József ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
Tato bakalářská práce se zabývá implementací systému vidění na dvounohý humanoid robot ze stavebnice Bioloid. Systém vidění je složen z bezdrátové kamery, která je namontovaná na robotovi a z řídícího počítače. Cílem této práce bylo zkonstruovat a oživit humanoidního robota, vytvořit systém vidění a bezdrátový komunikační systém. V centru je robot, který pomocí bezdrátové komunikace současně odesílá i přijímá údaje. Tento systém nabízí skvělé schopnosti na další rozšíření.
Renovace počítačové sítě ZŠ a MŠ Kanice
Kučera, Martin
The object of this bachelor thesis is a renovation of computer network at Elemen-tary School in Kanice. The task is to move the ICT classrooms and network ele-ments to the new floor. Another task is to lay out and create a wireless communication between buildings of the Elementary School. Final task of this thesis will be to create Wi-Fi for students, which will have a limited speed capacity. This thesis ends with the economical evaluation of the entire project.
