Implementation of IoT Communication Protocols Utilizing UniPi Module for Raspberry Pi
Krejčí, Jan ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
Presented diploma thesis is focused on the implementation of Wireless M-Bus protocol to embedded device RaspberryPi with expansion board UniPi. The protocol is implemented in Python with Wireless M-Bus devices communicating via IQRF transceiver connected to the UART bus. The theoretical part is focused on an overview of embedded devices for the IoT, the possibility of their expansion. Further, the UniPi expansion board and Wireless M-Bus transceiver are detailed. First part of the thesis focuses on the Wireless M-bus layers, which provides a basic knowledge for understanding the practical part. The theoretical part concludes overview of captured devices including a description of their data units. In the practical part is the implementation of the sample application for receriving data from a Wireless M-Bus sensors. The application is able to read data from devices transmitting encrypted communication.

Intelligent Security Camera Based on Raspberry Pi
Vinarčík, Peter ; Španěl, Michal (referee) ; Materna, Zdeněk (advisor)
The aim of this thesis is to create Pan-Tilt-Zoom security camera which will be constructed from Raspberry Pi and camera module. Camera tries to be compliant with ONVIF standard. Software of this camera is implemented in Python and partially in Node.js. Camera module captures 200 degrees field of view. Captured image is transferred as simulation of Pan-Tilt-Zoom camera with the help of computer vision - library OpenCV for Python. The resulting image will be possible to control and watch in network video recorder called Shinobi.

Management of the energy transmission system polygon
Bohačík, Antonín ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The diploma thesis is focused on the creation of a control interface for a polygon simulating the electrical distribution network of the Czech Republic, where communication between substations is realized by IEC 60870-5-104 protocol. The theoretical part of the thesis explains the basic principles, properties and possibilities of communication standards IEC 60870 and IEC 61850. The next part is focused on the actual implementation and subsequent implementation of the control interface, including the implementation of the IEC 61850-80-1 module for data transfer between the mentioned standards. The last part describes the created behavior scenarios or the analysis of communication itself.

Simulator of SCADA protocols
Bohačík, Antonín ; Mlýnek, Petr (referee) ; Blažek, Petr (advisor)
This work is focused on creation of fully functional communication generator of IEC 60870-5-104 protocol. The theoretical part explains in detail the basic principles, properties and possibilities of communication standards DNP3, IEC 60870 and IEC 61850. The next part is focused on the analysis of communication and implementation of this communication in the PQ MEg44PAN device. The last part deals with the configuration of Raspberry Pi 3 devices and the communication emulation of the IEC 60870-5-104 protocol. All programs were written and tested using the Clion development environment.

Imaging system in an aircraft for determining the position of ground objects
Lipták, Samuel ; Krejsa, Jiří (referee) ; Králík, Jan (advisor)
The bachelor thesis deals with the issue of identification of the position of ground signs based on the known position of the aircraft and images taken by the aircraft itself to participate in the international competition of aircraft models New Flying Competition 2022. The bachelor thesis analyzes the conditions of the competition and the resulting possible solutions. In the theoretical part, these options are described from a hardware and software point of view. The solution uses components from RaspberryPi and the MatLab environment for software analysis. Finally, the selected solutions are practically tested on a test aircraft and the photos are subsequently analyzed to confirm the functionality of the system.

Detection of Train Axles and Their Numbering According to International Union of Railways
Dvořák, Petr ; Zamba, Martin (referee) ; Strnadel, Josef (advisor)
The diploma thesis deals with design and development of the system which detects and numbers train carriages in compliance with International Union of Railways. Firstly, methods for correct detection of passing wheel including time records are analysed. Also, the summary of detection sensors used in railway industry is referred. I analyse meaning of each digit in numbering according to the UIC. The system solution is designed and the interaction and communication with other sub-systems is discussed. I put emphasis on the kind of solution that returns as accurate record as possible under any circumstances. The system operates in real time. Further, the results of measuring program are back-tested in order to verify low-deviation of measuring system component. The following section describes program prototype, which processes the recorded data. The algorithms which I used for the detection of wheel and train carriages are described. In the following chapter I discuss the usage of an external camera detecting the numbers in accordance to the UIC. In the last chapter, I describe the test environment in which the solution has been tested, and summarize the results of tests on a real life railway.

IoT WiFi soil moisture and temperature sensor
Kostelanská, Alžbeta ; Zeman, Václav (referee) ; Škorpil, Vladislav (advisor)
Bachelor thesis addresses the subject of IoT WiFi soil moisture sensor and temperature sensor based on ESP32 platform. The primary focus of the design is on low power consumption of the device and secure communication. The theoretical part of the thesis describes selected types of sensors which can be used for the designed device. The ESP32 module and some of its features are also introduced. Lastly selected communication protocols which are suitable for IoT applications and can be used with WiFi peripheral are discussed. The practical part of the bachelor thesis deals with hardware design of the sensor device and implementation of this design. Low power consumption is implemented in hardware and in software solution. The focus is on independence of the device and secure communication and data protection. Lastly the concept of webserver used for storing and processing collected data on RaspberryPi platform and concept of sending the measured data to the end-user are introduced.

Retrofitting Industrial Computer for Kiosk Application
Bužga, Petr ; Šoustek, Petr (referee) ; Dobrovský, Ladislav (advisor)
Industrial computers are designed to last for many years. This paper deals with the case where a computer was discarded from the laboratory as non-functional and it is desirable to try to revive at least some parts. The thesis first analyzes the possibilities of rebuilding the original Lauer VS386 computer. The use of RaspberryPi is proposed in the thesis. Then thesis proposes a driver for the original matrix keyboard embedded in the front panel of the computer as well as a kiosk application for managing employee attendance to verify the functionality of the rebuild computer.
