Power over Ethernet implementation
Šturala, Martin ; Musil, Petr (referee) ; Krajsa, Ondřej (advisor)
The aim of this bachelor thesis is to design and implement a power supply module for an end station network device with an optional 5 V or 3.3 V output, which supports power over ethernet technology, both for active and passive method of this technology. The work is focused on the design of a hardware solution to this problem. A Texas Instruments TPS2373 chip supporting the latest technology according to the IEEE802.3bt specification was chosen to implement active POE. The LM317 linear stabilizer was chosen to implement the passive POE.

Smart socket for electrical parameters analysis with possibility of controlling connected appliances
Musil, Libor ; Krajsa, Ondřej (referee) ; Musil, Petr (advisor)
Thesis deals with the design of intelligent electrical socket. At the beginning of the thesis, there are described the characteristics of the distribution network in the Czech Republic and the ways of measuring these properties. The selected integrated circuit that realizes the measurement is described in detail. The third chapter deals with the current possibilities of power management, especially from the perspective of the distribution company and the concept of smart networks. The fourth chapter deals with the selection of communication interface suitable for smart socket as an element of smart home. The selected IEEE 802.15.4 standard and the microcontroller implementing the communication itself are described in more detail. The following part of the work is about design of the intelligent socket development board, on which the concept is tested and the design of the final hardware is described in this chapter. The last chapter describes the measurement results realized by the created device.

BPL modem
Chromý, David ; Mlýnek, Petr (referee) ; Musil, Petr (advisor)
This work deals with the issue of PLC with a focus on BPL technology (Broadbandover-power lines), which is explained in the theoretical part. The work describes in detailthe main components for PCB design with manufacturing and mounting process. Fur-thermore, the thesis provides instructions on how to establish communication betweenBPL modems and a description of individual functions. In conclusion, the procedureof measuring the noise intensity in the 230 V power line is described with the results.The output of the diploma thesis is the selection of components and the implementationof printed circuit boards for two BPL modems. These modems allow to measure SNR(signal to noise ratio) at physical speed.

CIP industrial protocol simulation
Molent, Michal ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.

Temporal Tone-Mapping Methods for HDR Video
Staněk, Jiří ; Musil, Petr (referee) ; Nosko, Svetozár (advisor)
The diploma thesis provides the theoretical background needed to understand the complex topic of high dynamic range, and deals with the implementation of an innovative method for temporal video tone-mapping. At first, high dynamic range image acquisition, storage and processing are described. Afterwards, a general introduction to tone-mapping, description of undesirable image artifacts and an overview of existing state-of-the-art algorithms are presented. The part which follows focuses on the implementation of the chosen method and proposes several additional enhancements of the initially selected algorithm. Based on the information provided, an application with an intuitive graphical interface, which can be used for temporal HDR video tone-mapping, has been created. Finally, the the achieved results are demonstrated and visually compared with existing methods for temporal video tone-mapping.
