Inteligent Photo Printed Circuits
Kočík, Karol ; Šťastný, Ladislav (referee) ; Havlíková, Marie (advisor)
The goal of this Bachelor’s thesis is a design and implementation of an amateur PCB production device with photo printed circuits method. Different kinds of illumination and production processes of printed circuit boards are compared in an overview. In the chapter devoted to the construction of the device a brief description of the amateur device construction is made, which parts and functions it contains. Design of the device was focused on power saving and multifunctionality of the device. The last task after the construction of the device was to test the functionality and present the results.

SW for control tests and generating reports
Dočkal, Michal ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
The content of this work is the development of an application that serves as a graphical interface for running tests and generating reports. At first is marginally analyzed the process of measuring and recording, then the technology used in the development is described. As next, suitable implementations is proposed. Finally createed application is described, including outlining possibilities for further development.

SW for access panel of data concentrator
Kováč, Jakub ; Franek, Lešek (referee) ; Šťastný, Ladislav (advisor)
The aim of this work is design the software for operating panel of data concentrator. The work shows serial communication between human-machine interface and data concentrator. There are designed the communications protocol and graphical interface for device. Consequently is shown design of algorithm of control application. The algorithm is designed in view of battery supply by using of Low-power modes.

Token based authentication
Loviška, Martin ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
Thesis is dealing with possibilities of user authentication using a security token to Linux console and web applications. Theoretical part of this work is devoted to cryptography basics, particularly asymmetric cryptography algorithms . Thesis generally describes aut- hentication methods and includes a brief categorization of smart card devices. The practi- cal part deals with SmartCard - HSM device setup for a client and creating own certificate authority using this device. Finally, it presents a demonstration deploying smart card login to Linux and web applications using tokens.

Pump Control System
Streit, Jakub ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The goal of this thesis is design of universal system for motor control. This device must be able to control at least 4 motors, stepper motors or DC motors. Wired, or wireless communication, using IEEE 802.15.4, is mandatory. The System is based on modular concept. The Basic modules are Control module, Communication module, Connection module and Power module. The system was tested in the control of fertilizer dosing pumps in the greenhouse

Extension of biomass boiler
Kastner, Jakub ; Šťastný, Ladislav (referee) ; Burian, František (advisor)
Goal of this work is design and create extension data acquisition unit for existing system of heating boiler. Work is divided to theoretical and practical part. In theoretical part is mentioned methods of measuring temperature. Methods of measuring flue gas and placement of boilers into different classes according to standard ČSN EN 303-5:2013. The practical part deals with the design of schematic circuit for measuring the required parameters (lambda probe, thermocouple, measuring the light intensity using the photo-resist). Mechanical cover, testing created board under real conditions and the involvement of extension board into existing system of boiler. When commissioning the first version of the board appeared errors that were removed in the second version. In attempts to improve the operations of two boilers were found errors leading to the impossibility of any improvements.

Electronic parts of small fotovoltaic power plant
Benda, Dušan ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The thesis describes the design, implementation and subsequent testing of electronic circuits for usage in small photovoltaic power plants. It focused on the sub-power appliances, battery charging and monitoring of photovoltaic panels. Introduction of this work deals with selecting appropriate controllers for each subsystem and comparison of the proposed facilities with commercially available applications. A substantial part of the work describes the selected controller for each subsystem implemented and circuit design of the individual components of electronic systems in detail. For each subsystem are implemented measuring and comparing the results achieved.

Wireless data acquisition system
Kováč, Jakub ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
The aim of this work is design of system for wireless data collection from energy meters. The work shows issues of smart metering and explains meters communication. There is designed and described concept of the system composed of RF modules connected to data concentrator. Designed RF module uses SoC radio CC430F5137 and it is connected to a data concentrator via RS485 bus. For the purposes of communication as well as firmware update, the communication protocol is designed. In the next part the work focuses on design and creation of RF module frmware, bootloader for RF module and software application for energy meter data processing.
