2D ultrasonic positioning
Junek, Jiří ; Šťastný, Ladislav (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with the implementation and evaluation of measuring directional and omni-directional ultrasonic senzors. Control of ultrasonic senzors and computation of a distance is realized by using a microrontroller Arduino Duemilanove. The first part deals with the measurement of directional sensors, their wiring and subsequent processing of the measurement is performed in Matlab. The second part deals with solving of measuring and visualization 2D position omni-directional ultrasonic senzors, implementation trilateration algorithm for calculating x and y coordinates and comparison the used filters. At the end of this thesis also includes a comparison of directional and omni-directional ultrasound and evaluate their applicability for measuring 2D position.
Microcontroller based system equipped by light sensor
Judiny, Martin ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The aim of this bachelor thesis was to develop and describe the concept sensor of lighting, controlled by microcontroller. In first part is theoretical evaluation of our task and in second part are developed schematic and PCB. Based on theoretical analysis has been chosen the most appropriate sensor.
Control of lab models using PLC
Vobejda, Lukáš ; Šťastný, Ladislav (referee) ; Štohl, Radek (advisor)
This work deals with the control of lab models using PLC Rockwell Automation. As well as the use of CompactLogix, RSLogix 5000 programming environment, RSlinx Classic communication environment and software for process visualization such as FactoryTalk View Studio. The first part deals with the description of the models and their connection to a PLC environment. The second part describes and compares programming languages (ladder diagram, function block diagram and sequential function charts). The last part deals with the visualization of both models in FactoryTalk View Studio.
Home security system - base board power supply
Peša, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
This bachelor's thesis deals requirements for alarm system power supplies and includes familiarization with the issue of charging lead-acid batteries and an explanation of the basic principle activity step-down switched – mode power supply. The main goal of this project was to design and implement a functional model of the power supply with lead-acid battery. The power supply includes a battery charger circuit, which when accompanied by a power failure back-up and circuit protects the lead-acid battery against deep discharge UPS is in normal operation continuously charged. The proposal was developed in the program for PCB design Eagle 6.1.0. Functional model was implemented in a single PCB, which together with the battery and transformer were placed in the box.
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.
