Weather Station with Ethernet Interface
Novák, Pavel ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
This thesis deals with the design and construction of the meteorological station. The meteorological station is designed and constructed to be able to measure the basic meteorological parameters (temperature, humidity, air pressure) and the other three variables (measuring rainfall, wind speed, wind direction). This thesis will introduce you to meteorology. Meteorology determines the daily weather forecast and the results are used for examples in aviation or maritime affairs. The method of atmospheric origin is given in the theoretical part. Meteorology must use measuring instruments to determine quantities. The dissertation also includes analysis of the measuring instruments. The meteorological station uses the Ethernet technology. In the chapter devoted to Ethernet are described its principles, types and method of power supply over Ethernet. The following section describes the design of the entire meteorological station, selection of all components and description of their connection. The chapter about implementation contains a description of the parts which forms program part of the meteorological station. The aim of the thesis is a summary of the achieved results including price comparison of the renovated meteorological station with other meteorological stations, which can be normally bought.

Smart signaling unit
Stejskal, David ; Bradáč, Zdeněk (referee) ; Baštán, Ondřej (advisor)
The essence of this bachelor thesis is a complete design of hardware and software solutions and subsequent implementation of a Smart Signaling Unit. It is intended to replace the currently installed signaling beacons and to improve the existing testbed Self-Acting Barman with its features. The designed device is able to signal machine states according to the PackML standard. It can also communicate via Ethernet using the industrial communication protocol Modbus TCP, while implementing a Modbus server, which provides services for other connected devices (Modbus clients). The device also implements the Power over Ethernet (PoE) standard, thanks to which it is possible to power the signaling unit directly via an Ethernet cable, on which communication also takes place. At the beginning, the main goals of the work are presented together with the requirements for the Smart Signaling Unit. Subsequently, the importance of signaling units in the industry is explained and the basic parameters for the selection of a specific product are given below. Following this, a survey of available signal towers on the market was carried out. In the theoretical part of the work, the Industry 4.0 initiative is first described in more detail, on the basis of which the testbed Self-Acting Barman is briefly introduced. The following is a comprehensive description of the industry standards PoE, Modbus TCP and PackML used in device design. The concept of the signaling unit already belongs to the practical part of the thesis and deals with the methods of display, which represent the primary function of the Smart Signaling Unit. An integral part is the hardware concept, which describes the most important used components. The final part of the work deals with the creation of a printed circuit board and the development of firmware using the Visual Studio Code development environment and the framework ESP-IDF from the company Espressif.

Multichannel Audio Signal Transmission Over Local Area Network
Kotouček, Filip ; Frenštátský, Petr (referee) ; Schimmel, Jiří (advisor)
This thesis deals with design and implementation of multi-channel audio signal streaming via local network. The aim was to choose suitable processor for the transmission of up to 32 channels of audio signal, which will be used for implementation. Also the low-latency ASIO driver was studied and was used to provide timestamps for synchronization. The transmission protocol was designed for signaling and for the real time stream. The actual transmission is provided by TCP protocol. In conclusion, I created the application for development board with choosen MCU. Finally whole solution was tested with real data.

Design and implementation of managed PoE injector
Frkal, Pavel ; Frolka, Jakub (referee) ; Krajsa, Ondřej (advisor)
This study deals with power supply for network devices using existing structured cabling. Various power supplies are analysed including their limitations and also deals with measuring of the consumed energy. The outcome is 24-port passive PoE injector for remote power supply of network equipment. It's suitable namely for remote devices which lacks built-in PoE support as these do not need major modifications (using passive injection). Power options including current measurement may be done via administrative web interface.

Design and implementation of a universal NFC reader.
Jirásek, František ; Kaczmarczyk, Václav (referee) ; Baštán, Ondřej (advisor)
The essence of this bachelor´s thesis is the design and subsequent implementation of a universal NFC reader, which will be built into the school Testbed called "Self-employed bartender". The reader will act as a base for glasses containing NFC tags, from which it will then be able to find out the complete recipe of the final product to be mixed into the glass. In addition, all performed functions will be signaled by RGB LE diodes.

Power over Ethernet
Hykš, Matěj ; Šilhavý, Pavel (referee) ; Koton, Jaroslav (advisor)
The bachelor thesis focuses on the topic of powering network elements using Power over Ethernet shortly PoE. The work focuses more in detail on the functions of the 802.3af and 802.3at standards, which are described in detail and explains their functionality on specific examples of PD chips. Then it summarizes the measurement methodology used for 3 devices belonging to the PSE category and 4 devices from the PD category. In both cases, it focuses on their analog and digital communication.

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.

Project Defence Timekeeping System
Navrátil, Michal ; Crha, Adam (referee) ; Růžička, Richard (advisor)
Goal of this thesis is to design and assemble ethernet module for time measuring panel containing watch and stopwatch which will provide network interface to this panel and will power it through ethernet. One of requirements was to develop a control application for microprocessor controlling watch and stopwatch which loads time via this module from the internet and it sets the watch. Stopwatch is controllable via network through control application which was created as part of this thesis. For this purpose there was created a server running on the microprocessor which interacts with control application. Executables of control application are generated for operating systems Windows and Android. It is easy to run it on Linux as well. Contribution of this thesis is possibility to easily track time from the pc or the phone where student and examiner will have a precise information about time.
