Learning set inovation
Hrdlička, Martin ; Baštán, Ondřej (referee) ; Kaczmarczyk, Václav (advisor)
This bachelor thesis deals with the modification and commissioning of an older training set. The training set demonstrates the transport and sorting of the material. It consists of a material hopper, a conveyor and a manipulator. The work requires modifications to the control board firmware, program design for PLC and physical modifications. The whole process is controlled by a PLC and is controlled by an HMI started in the simulation. The result of the work is a functional training set.

Security Analysis of Home IoT Network
Čikel, Tomáš ; Jeřábek, Kamil (referee) ; Pluskal, Jan (advisor)
This work focuses on the issue of the security in home IoT network. Specifically, it focuses on the security issues of commercial IoT devices and their automation systems. In the work itself, it was firstly analyzed and identified specific threats specific for our network. To address these threats, the original automation systems and firmware on the devices were replaced by open-source implementations that were configured to address discovered threats. Although, there are still several security issues in a network with an open-source implementation, a large part of the security issues which were discovered has been eliminated. The results of this work allows to configure a home IoT network using an opens-source automation system and firmware and proves that such a network is more secure than the network where the original factory-supplied automation systems and firmware on devices are used.

Analysis of Wi-Fi traffic
Bakó, Zdeněk ; Pospíšil, Ondřej (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with the capture and analysis of wireless traffic of Wi-Fi networks. The aim of this work is to describe the possibilities of capturing and analyzing the operation of Wi-Fi networks. It describes the IEEE 802.11 standard, its features such as architecture and current standards. A selection of a suitable router is performed on which traffic capture and analysis is performed. Some open-source firmware for routers is compared and the most suitable one is selected. Tools for capturing and analyzing Wi-Fi network traffic are compared and described. The differences between the promiscuous and monitoring capture mode and their possibilities of use are described. Finally, there are described options for analyzing captured 802.11 frames.

Building a 3D Printer
Škop, Martin ; Klepárník, Petr (referee) ; Španěl, Michal (advisor)
The aim of this Bachelor thesis is to analyse available options for 3D printing using FDM technology according to requests of cooperating company, to propose several drafts of electronical and software parts of 3D printers. This also includes their connection, functionality testing and implementation of one chosen draft. The core of this Bachelor thesis was to document the progress in building the 3D printer and also to solve arisen problems. The result of this Bachelor thesis is practical realisation of electronic part of 3D printer including basical tests. Secondary benefit of this Bachelor thesis is to explain the issue of 3D printing with the option of building custom 3D printer from PiBot components.

Firmware for partial discharge calibrator
Turinský, Matěj ; Baštán, Ondřej (referee) ; Fiedler, Petr (advisor)
The goal of this thesis is to create a firmware which realizes processor control for a given hardware (calibrator of partial discharge meters). Thesis describes what options are availible in the field of processor control of devices, their advantages, disadvantages and possible applications in real life. Concrete realization then provides a closer look on firmware creation in C programming language for STM32 processors using the standard CMSIS interface.

Design of evaluation network for in-vehicle networking communication chips
Kupčík, Ondřej ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
Cílem této diplomové práce bylo navrhnout moduly určené k demonstraci a testování některých obvodů, používaných v automobilové technice. Jedná se o LIN transceiver NCV7420 a osmivýstupový výkonový budič AMIS-39101. Návrh spočíval ve vybrání a popisu parametrů vhodných podpůrných obvodů, vytvoření celkového schématu a navržení desky plošných spojů tohoto modulu s ohledem na kompaktní rozměry a předpokládané testy. Dalším krokem byla tvorba firmware řídicího mikrokontroléru (C8051F344), jež zajišťuje LIN komunikaci, řízení budiče a základní monitorovací funkce. Poslední část popisuje software pro hostitelský PC umožňující komfortní řízení sítě složené z těchto modulů. Pro úplnost byl tento projekt doplněn o přehled vlastností sběrnice LIN a metodiky testování LIN transceiveru z hlediska funkčních parametrů i některých EMC měření. V příloha obsahuje kompletní schéma modulu, výkresy desek plošných spojů, seznam řídicích příkazů a fotografie modulu.

Communication of USB3.0 Chip with FPGA
Špeťko, Matej ; Viktorin, Jan (referee) ; Košař, Vlastimil (advisor)
SEC6NET is an abbreviation for project Modern tools for detection and mitigation of cyber criminality on the New Generation Internet. Project is focused on research and development of means for monitoring and analysing the network flow. Probes for monitoring IPv6 networks are developed within this project. Probes are using hardware acceleration based on FPGA platform. My thesis connects two technologies: FPGA and USB. The goal is to transfer data from the FPGA microchip to PC using Cypress EZ-USB FX3 microcontroller. The first part is focused on transferring data from FPGA to FX3 microcontroller. Second part describes the modification of FX3 firmware for getting maximum throughput. The last part focuses on implementing PC application for Linux operating system. The application receives data from the probe and saves them into hard drive using PCAP format.
