Program update of Zynq-based devices
Michálek, Branislav ; Buchta, Petr (referee) ; Kubíček, Michal (advisor)
Among many which are placed on modern embedded systems is also the need of storing multiple system boot image versions and the ability to select from them upon boot time, depending on a function which they provide. This thesis describes the development of a system update application for Xilinx Zynq-7000 devices. The application includes a simple embedded HTTP server for a remote file transfer. A client is allowed to upload the boot image file with the system update from either command line application or using the web page developed for this purpose.
STEMLab based data acquisition system
Pavlík, Radim ; Kováč, Michal (referee) ; Kubíček, Michal (advisor)
Thesis deals with design of acquisition system, working on developing platform STEMLab (Red Pitaya). Goal is possibility of monitoring analog signals with adjustable sampling frequency and length of acquisition. Software was created for both controlling part (Python application) and for platform itself (embedded C, Python) using the appropriate FPGA-HW design (HDL). Thesis describe how to work with platform ecosystem, control and behaviour of aplications created during the proces of getting acquainted with the platform and options how aplications could be created.
LED driver with synchronous rectification
Hodáňová, Adéla ; Šotner, Roman (referee) ; Kubíček, Michal (advisor)
The main goal of this diploma thesis is to compare two circuits designed for LED powering with output current of units of Amperes. Both circuits are based on step-down converter topology, one with technology of synchronous rectifying and the other one without it. Calculations and selection of used components with real prototypes were made for both selected circuits. All selected components meet automotive qualification requirements for discrete products. Produced prototypes were compared in terms of functionality, efficiency, EMC and thermal radiation.
Nano-ammeter with galvanic isolation
Šimka, Marek ; Kubíček, Michal (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with all the aspects, that are important in the designing of the nano-ammeter. In theoretical part, there are described possible ways to measure electrical current of very low values. Other parts of the thesis describe all parameters, which are influencing measurement accuracy. These are, for example, unwanted and leakage currents, but also other parasitic phenomena that may occur. Thesis explains how to minimize unwanted currents and other influences. Practical section provides more detailed description of the proposed main scheme. There are also described components, that have been selected as the main parts of the nano-ammeter circuit. Subsequent part contains analysis of printed circuit board including all layers. Furthermore, the thesis deals with the realization of equipment and possible errors. The results of the bachelor are summarized in the last chapter.
Radar antenna diagnostic module
Pacner, Petr ; Urbanec, Tomáš (referee) ; Kubíček, Michal (advisor)
Faults like open and short circuit in electrical wirings pose a significant threat on functionality of the whole application. This thesis describes conceptual design of a fault identification module for coaxial cables between transmitter and antenna in radar systems, and focuses on faults localization. The main goal is to select from existing a suitable method for such faults analysis and create a demonstration module serving as a basis for further development. This contains theory regarding basic classification of wiring faults and principles of frequently used detection methods including some of their prameters, advantages and disadvantages which altogether build a foundation for method selection. The chosen method is analyzed by simulations and further on laboratory equipment controlled by a set of computer applications. In the end the chosen method is implemented on a development kit, which is then used for measurements of wire sample.
The robotic system state indicator
Kovaľová, Alžbeta ; Kubíček, Michal (referee) ; Šotner, Roman (advisor)
This bachelor thesis deals with the design and creation of a status indicator for robotic system developed in Y Soft. Part of this work is the design and implementation of communication between the status indicator and the superior device testing system. A printed circuit board is designed and constructed, and then a microcontroller is programmed and the CAN bus communication is implemented. Subsequently, the device is integrated into the company system for robotic testing, where its functionality is verified.
Digitizer for radar senzors
Cích, Augustín ; Šebesta, Jiří (referee) ; Kubíček, Michal (advisor)
This bachelor thesis deals with digitization of analog signal of radar sensors, which employ Doppler‘s effect. Radar sensor used for construction of prototype was HB100. Digitization was done with ADC, which has 12 bit resolution and sample rate of 15,625 kS/s. Control unit of aquisition is Arduino UNO, which sends data to computer, where they are, in application interface made in MATLAB, processed using „watterfall“ spectrogram.
Investigation of Ionizing Radiation Infuence to the Communication Systems of Satellites
Golubev, Martin ; Kubíček, Michal (referee) ; Katovský, Karel (advisor)
This master thesis discuss about ionizing radiation, interaction with matter and effects on her. In the work is discussed differend types of interactions of directly ionizing radiation and indirectly ionizing radiation. Below is an overview of methods of shielding from all of types of ionizing radiation. Second part of this thesis discuss about single event effects in semiconductors which are cause by ionizing radiation. At the end is described design of measuring instrument included FPGA chips. This design is discused both from point of wiew hardware and software too.
Optical communication interface for LaserGame
Vykydal, Jan ; Povalač, Aleš (referee) ; Kubíček, Michal (advisor)
This work deals with the design of the communication interface in the infrared band of electromagnetic waves, which will be applicable to the laser game.
Wireless IR Sensor for Area Invasion Detection
Suchý, Lukáš ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The target of this Bachelor thesis to design a security system for detection of the monitored space disruption, containing several battery powered sensors which are connected to central unit. From Bachelor thesis is evident, that for communication is to be used integrated circuit SI4432. Sensor detects motion in distance no less than 5 m and sends reports of the space disruption to central unit where this information will be processed. After that the user will be informed by the central unit. Sensor unit should be battery powered with lifetime in years. In conlusion, the system it tested in real work.
