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.

Data concentrator
Dvorský, Petr ; Arm, Jakub (referee) ; Fiedler, Petr (advisor)
The topic of this thesis is the design and realization of a modular Data concentrator for various types of measurements in diverse conditions. The device conception, basic principles, design and functionality are described herein. Also, the lightweight protocol design for radio communication, standardized XML format for data storage and cloud usage are described. The electrical design of the device as well as the design of the printed circuit board was made using the Eagle Autodesk electronic design automation software (Eagle Autodesk EDA). The control software written in C/C++ for a target microcontroller (ESP32-WROOM-32) is based on a FreeRTOS platform and ESP-IDF framework. An IDE for managing this software is Visual Studio Code with PlatformIO extension. Selected and used Cloud Platform is ThingSpeak from Mathworks, which uses certain components from Matlab platform.

Nixie clock
Ščípa, Samuel ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This thesis focuses on the design and implementation of a nixie clock. In the introduction, the thesis deals with the history of the origin and the principle of the function of this vintage technology. It describes in detail the function and design of the support and control circuits to operate these character discharge tubes. It addresses the design and implementation of the hardware part of the clock. Further, the software part of the device is discussed in detail, which provides the normal functionality of the clock, such as stopwatch, alarm, timer, temperature measurement, supplemented with modern features such as Wi-Fi, RGB backlight a USB-C for power and programming. The final stage is the implementation and testing of the finished device.
