Automatic reading of numbers - real-time measurement of quantities from graphical displays of various instruments with a camera
Bartoš, Daniel ; Králík, Jan (referee) ; Appel, Martin (advisor)
This bachelor thesis deals with the process of converting numerical values displayed on graphical displays of measuring instruments without communication interfaces into data usable for subsequent analysis, using a camera and a program described in the implemen- tation section. The theoretical part is dedicated to the research and implementation of operations used in image processing, including morphological operations, in the MATLAB environment. The practical part of the thesis focuses on creating a program for real-time recording of numerical displays using a camera, processing the captured images with operations discussed in the research section, and reading them using the MATLAB OCR function. It also covers the subsequent processing of the read data and their storage during the measurement. This part also includes examples of measuring different types of displays, creating a user interface and application using the Application Compiler tool. The thesis concludes with a section serving as a user guide for the application.

Racecar Dash
Listoň, Martin ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The topic of this thesis is displays for racing cars. It includes a summary and brief comparison of the different types of displays as well as the current range of panels available from commercial brands. The following part of the thesis is devoted to the implementation of the creation of a custom display panel, which consists of primary scanning, testing and subsequent laboratory simulation, as well as the creation of the PCB design for the display interface from the vehicle's CAN bus, the compilation of the final code in the Arduino IDE software environment, the creation of the GUI (Graphical User Interface) in the Nextion Editor program, and also the structural design of the instrument panel including printing and assembly. The final part of the thesis is the verification of the functionality of the created complex device and the evaluation of the results. The main goal of the thesis is to create a functional complex device that is more affordable than the currently offered devices on the market.

HMI for a 3D milling machine using FactoryTalk Optix
Uher, Adam ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
The thesis focuses on the design and implementation of an HMI (Human Machine Interface) for 3D milling machine. Basic visualization rules, best practises, principles of ergonomic design, and the creation of user interfaces are described. Visualization tools for the LOGIX PLC series are outlined, which can be utilized in HMI development. Following the guidelines and specified requirements in this paper, a design for HMI is created using the FactoryTalk Optix visualization tool. Changes to the functional safety and PLC program are identified and implemented. Subsequently, the visualization of the milling machine is carried out and the functions of the new system are subjected to testing.

Universal Graphic Editor of Screens for LCD Devices
Šmejdíř, Radek ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis aims at development of a universal graphic screen editor for LCD devices made by Honeywell. The editor is one module of a complex application, which serves automated testing of thermostats and similar devices. In the editor a display layout can be designed, as well as the individual screens. The output is stored to an XML file. The application is written in C# and must be executable in the Microsoft .NET Framework.

Stopwatch for measuring of sports events
Tajč, Martin ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
The aim of this bachelor work is the construction of the electronic stop-watch for measurement at sports events. This stop-watch is primary designed for use at firefighters competitions. The first part of the work is focused on a flowchart of the stop-watch and an analysis of its parts. Some alternative methods, which could be used during the construction, are compared. In the following part, there is an algorithm for the microprocessor applied in it described and features of programming languages are briefly compared. Next in the text, there are a detailed user manual as well as a manual for executing of the display panel. In the supplement, particular electronic schematics and printed wiring boards are included.

HC08 Microcontroller Development Kit
Hájek, Ondřej ; Sekora, Jiří (referee) ; Čížek, Martin (advisor)
Presented bachelor degree programme is aimed on design and implementation of a development board for Freescale HC908QB8 microcontroller from HC08 family. The board will allow the user to test a variety of typical microcontroller applications including temperature measurement, intelligent LCD interfacing and I2C bus communication. The development board can be programmed using universal DBG08 serial programmer. Care was taken to minimize the probability of an accidental misconnection causing potential damage to the circuit, which makes the device suitable for educational purposes.
