Remote data downloading from automotive digital tachograph
Matoušek, Vojtěch ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
Thesis deals with device firmware design located in lorry, which provides remote access to vehicle digital tachograph data according to valid EU legislation. The result of this work is a system, which downloads digital data from digital tachograph and save them on remote server. The system for remote data downloading from automotive digital tachograph consists of three kinds of applications: server application, user application and firmware for communication device. Communication between applications uses encrypted TCP connection and own special designed messages.

High performance data acquisition communication line
Hadámek, Jakub ; Petyovský, Petr (referee) ; Valach, Soběslav (advisor)
The aim of this thesis is the acquisition of data from the AD converter and it’s transfer via the JESD204B interface to FPGA with the following transformation and transfer to PC through 100G Ethernet or PCI Express interface. The first part of the thesis is focused on the introduction to used technologies and hardware and analysis of the solution of this project. Second part of the thesis describes solution and it’s functionality. I created HDL design which allows to transfer data from AD converter using both of the interfaces mentioned above. I also created software application for OS Linux which allows to receive and store incoming data in PC. In the end, the results of the measurement using the converter board are presented and discussed.

Diagnostic tool for SD card protocol
Frnka, Peter ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
The objective of this diploma thesis is to design and implement a diagnostic tool for communication protocol of SD memory cards. The diagnostic tool will be able to monitor and interfere with communication of an SD memory card. The hardware implementation will be based on platform with Kinetis K66 microcontroller. A PC application designed for windows is also a part of diagnostic tool. There is a conclusion of the diagnostic tool limitation at the end of the thesis.

Small CNC cutting machine
Golej, Juraj ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This bachelor thesis deals with design and realization of a large format 2D CNC machine for cutting thin soft materials, especially the cardboard. In the first chapter I describe the available solutions on the market, their properties and parameters, including the tools. In the second chapter I create a design of the mechanical construction. The emphasis is on a simple modular structure using V-slot aluminum profiles. The third chapter describes the design of control electronics, where the main role has stepper motor driver with chip TB6600HG and microcontroller ARM Cortex-M7 from Microchip, where the main program is running. The final device can read data from SD card and perform an automatic cutting process without complicated user operations.

Traffic assistant system for complicated situations
Podola, David ; Janáková, Ilona (referee) ; Petyovský, Petr (advisor)
T-intersections are one of the most common places where collisions happen. An intelligent traffic mirror is one the possible solutions to reduce the accident rate. The mirror detects the situation around the intersection, process the data and provides the driver with an information, whether the situation is safe and the driver can enter the junction safely. The aim of the thesis is a feasibility study of reliable detection of non-stationary objects based on cameras. The core of the intended product – the detection algorithm – detected the object on short distance from the camera reliably but as the distance was growing, the detection quality degraded. One of the possible solutions to achieve better detection results on longer distances may be achieved by using a camera with greater zoom. Based on the example improvement proposal, the feasibility of the solution based on optical methods was finally confirmed.

A convolutional neural network for image segmentation
Mitrenga, Michal ; Petyovský, Petr (referee) ; Jirsík, Václav (advisor)
The aim of the bachelor thesis is to learn more about the problem of convolutional neural networks and to realize image segmentation. This theme includes the field of computer vision, which is used in systems of artificial intelligence. Special Attention is paid to the image segmentation process. Furthermore, the thesis deals with the basic principles of artificial neural networks, the structure of convolutional neural networks and especially with the description of individual semantic segmentation architectures. The chosen SegNet architecture is used in a practical application along with a pre-learned network. Part of the work is a database of CamVid images, which is used for training. For testing, a custom image database is created. Practical part is focused on CNN training and searching for unsuitable parameters for network learning using SW Matlab.
