Meteorological Station with Remote Access
Svoboda, Josef ; Číž, Radim (referee) ; Sysel, Petr (advisor)
This thesis discusses design and realization of air temperature, pressure and relative humidity measuring device, transmission of measured data over internet and their presentation on a web site. First chapter introduces reader into principles of measuring air temperature, pressure and relative humidity and various types of sensors used for measuring . Next, the conception of designed system is described. Designed system must accomplish tasks from reading raw data from the sensor up to thein graphical presentation to the internet user. Second and third chapter describes hardware and software design of air temperature, pressure and relative humidity measuring unit. In next part one can find description of software used to transmit measured data over internet and software for generating web pages which are shown to users. The work is revieved in the final part of this thesis.
Wireless Remote Controller for Linear Repeater
Veselý, Tomáš ; Šebesta, Jiří (referee) ; Rumánek, Jaroslav (advisor)
The project deals with the problems of the wireless remote control of the linear repeater. The implementation is devided into two function parts. The first part is a network focusing on the input of instructions by the user, processing of the information, displaying the actual setting and sending the information on the given instructions. The second part deals with processing of the given information from the first part and its discharging. Both parts are controlled by the microprocessors.
Controlled power generator of current impulses
Gabriel, Viktor ; Vrba, Kamil (referee) ; Rampl, Ivan (advisor)
The goal of this thesis is to design and realise microprocessor-controlled generator of current impulses, which are being brought in induction load. Thesis contains description of individual functional generator parts, mainly microprocessor program equipment. The text also aims for inductor design as an induction load and other solutions of power parts with the selection of the most suitable one. The generator of current impulses itself is realised on two-sided printed circuit board.
Automatic measurement of the motor vehicles distance.
Juřica, Lukáš ; Chmelař, Milan (referee) ; Říčný, Václav (advisor)
This work deals with evaluation of equipment used for non-contact measurement of distance between vehicles. First are discussed various principles of measuring and after the selection of the most appropriate solution is proposed a detailed block diagram of modulation, demodulation and evaluation of the whole system and its mathematical description. Another part is devoted to describing the activities of the microprocessor controller, with which is controlled evaluation part and to the control program. It also analyzes the maximal attainable accuracy of measurement and the errors that affect it. The last part includes a circuit design and simulation of selected functional block, which is a coincidence /quadrature/ detector and construction documents for evaluation and demodulation part of the measurement instrument.
Educational laboratory kit for microprocessor technique
Hána, Jan ; Chmelař, Milan (referee) ; Kolouch, Jaromír (advisor)
Thesis deals with support of educational courses focused to single chip microprocessors in secondary schools. It includes a text introducing students to the use of single microprocessor and provides examples to their applications.
Doppler's sensor beat freqeuncy proccessing
Dušek, Martin ; Macho, Miloslav (referee) ; Fuchs, Michal (advisor)
This work is engaged in ways of objects speed measuring mainly helped by Doppler Effect. The sensor HB410 is described in this work and its possible elaboration output heterodyne analog signal. The calculation of objects speed is deduced from frequency of heterodyne signal. In this work is projected circuit solution for elaboration of analog signal and its digitalization. Available types and nature of microcontrollers which are elaborating digital signal and communicating with PC are summarized in this work. In the last chapter is described microcontroller's driving software and PC software for speed measure.
Prototype realization for RFID system demonstration
Pernica, Josef ; Šimek, Milan (referee) ; Pfeifer, Václav (advisor)
This diploma thesis deal with design and realization of demonstration board for RFID system. In the begining is described theory of this system. Next part is about theory of solutions and used components. Next is about practical realization demoboard and control program in C language.
Multimedial education interface for programming and debugging software for AVR microcontrollers
Šrajla, Josef ; Sajdl, Ondřej (referee) ; Pavlík, Michal (advisor)
Diploma thesis is concerned with programming of AVR microprocessors. Main task was development of compact environment where user can learn methods necessary for successful programming of microprocessor. It was necessary to make an application enabling interactive simulation of processor to reach this goal. User-friendly control, simplicity and low hardware demands are main advantages of this application. Only computer with internet connection is demanded. Complicated installation, usual for similar products, is avoided.
Control Unit for Humanoid Robot
Florián, Tomáš ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The main goal of this project is to understand broadband sold Robonova-I humanoid robot and to design new improvements. The thesis is divided into five main chapters: The first of them (Robonova-I) is concerning the kit of Robonova-I, its completion and control possibilities. In details it deals with used servo motors, their operating and compares them. The next chapter is concerning the design of the control unit along with description of architecture of the processor and control possibilities with demonstrational board. In third there is a software solution of particular methods and commands which control the unit with demonstrational board. Chapter “The Design of Printed Circuit Board” describes facilities of the designed printed circuit board. The last chapter describes the final program for robot control through the use of computer and some of the algorithms by means of which the robot controls the microprocessor.
Wireless doorbell with digital voice transmission
Partsch, Patrik ; Šebesta, Jiří (referee) ; Mikulka, Jan (advisor)
The master´s thesis deals with a design and layout of wireless doorbell with digital voice transmission. It also includes the nRF9E5 circuit analysis. In the beginning of the document there is characterization of the problem in general. Next part describes a layout example for the application schematic, a layout of printed circuit board and a layout of software. nRF9E5 is a true single chip system with fully integrated RF transceiver, 8051 compatible microcontroller and a four input 10 bit AD converter. Despite of all studies of available literature I have found only very little particular information related to this matter. In general, the main aim of this work is to make the wireless doorbell with digital voice transmission. Further, ilustrated schematics are enclosed as a attachement of this thesis.
