Design and developement of autonomous system for monitoring critical paramaters in food industry
Chovan, Hynek ; Formánek, Martin (referee) ; Krejčí, Petr (advisor)
his work focuses on automating the monitoring of temperature and other operational parameters in gastronomic establishments. The designed device allows real-time monitoring of temperature, humidity, and other parameters with remote access capability. It utilizes the ESP32 microcontroller, SHT40 and HX711 sensors, and TP4056 charging circuit with DW01A protection circuit. Data is transmitted to a Gateway device, which displays it through a web interface. Testing demonstrated sufficient communication range and long battery life. The device meets requirements for compactness, reliability, and efficiency. This project represents progress in IoT applications for ensuring food safety and efficiency in handling food in gastronomic establishments.

An efficient and general abstraction of middle layer for embedded Linux
Drexler, Filip Emanuel ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
Cieľom tejto práce je návrh a konštrukcia medzivrstvy vo vstavaných zariadeniach s operačným systémom GNU/Linux. Medzivrstva je softwarová vrstva, ktorá pomáha s abstrakciou hardware, medziprocesovou komunikáciou, genericitou kódu a čistejšou softwarovou architektúrou. Bola skonštruovaná s nástrojmi ako D-Bus a modelovacím jazykom YANG, čo viedlo z zmenám v softwarovej architektúre a jasnejšiemu designu. Niektoré nízkoúrovňové časti kódu boli presunuté do procesu, ktorý poskytuje rozhranie pre iné procesy. Výstupom je vhodnosť takejto medzivrstvy, výhody ktoré poskytuje, ale aj nevýhody.

Time synchronization by IEEE1588 protocol
Hříbek, Šimon ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
The thesis focuses on implementing time synchronization using the PTP protocol on the STM32H747 platform to assign precise timestamps to acquired samples using the ADC converter. The chosen platform is specifically the STM32H747 Discovery Kit development board. The thesis includes a description of available libraries necessary for implementing time synchronization. One area also covers the procedure for setting up the Ethernet interface available on the development kit. The thesis also addresses the selection of suitable methods for evaluating the achieved results.

Development Board for 32-bit Microcontroller Atmel AT91SAM9261
Demín, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Vestavený hardware je velice populární v této době. Proto jsme se rozhodli vytvořit desku s mikrokontrolérem AT91SAM9261 spolu so standartným a nestandartným hardwarem. Standartným, běžným by se dal nazvat port LAN alebo audio vstup-výstup. Nestandartným, špecialním by mohl být obvod FPGA firmy Xilinx o velikosti 200k. Toto dovoluje využít zažízení v oblastech, kde výpočetní síla obyčejnýho CPU již není dostačující.

Intelligent LED Light
Krejčí, Martin ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
The aim of the bachelor thesis is to design and implement a prototype of intelligent LED lighting with the possibility of mixing colours (cold white, warm white, red, green and blue) and with integrated motion, smoke, temperature and pressure sensors, which can be connected to an island photovoltaic system. Create a control unit and a W(LAN) unit that will allow communication outside this closed bus using a web interface. Establish appropriate and reliable communication between all proposed system units. The thesis first describes lighting, its history and the use of multi-colour LED lighting today. Then all the buses used are described. The design of the device itself consists of a 3D model of the prototype LED lighting embedded in the ceiling, followed by the selection of the specific integrated circuits, microcontroller kits and other peripherals needed. At the end of the paper, the measurement results of all the designed components of the device are summarized.

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.

Embedded system design
Gábor, Tomáš ; Galetka, Josef (referee) ; Götthans, Tomáš (advisor)
This work deals with application of ARM based development board as platform for remote controlling of attached peripherals. It describes practical experiences with A20- OLinuXino-Micro-4GB development board and it’s available options. Used hardware and testing peripherals are described in the next part along with programming of the software for web interface and for communication in between development board and peripherals. The second half of this document describes design process of own embedded system beginning with schematic, continuing with PCB wiring. Each step of PCB wiring process is described with required details in text, including crucial connections between processor and memory chips. The last part contains details about setting a calibration of memory chips and designing optional peripheral modules.

Implementation of Deep Learning Algorithm on Embedded Device
Ondrášek, David ; Boštík, Ondřej (referee) ; Horák, Karel (advisor)
This thesis deals with the implementation of inference model, based on the methods of deep learning, on embedded device. First, machine learning and deep learning methods are researched with emphasis on state-of-the-art techniques. Next, the best suitable hardware had to be selected. In the conclusion, two devices are chosen: Jetson Nano and Raspberry Pi. Then the custom dataset, consisting of three classes of candies, was created and used for training custom inference model through the transfer learning technique. Model is later used in the application, capable of object detection. Application is implemented on Jetson Nano and Raspberry Pi and then evaluated.
