Pellet grill control system
Vařečka, Ondřej ; Friml, Dominik (referee) ; Dokoupil, Jakub (advisor)
This thesis focuses on determination of basic requirements for a pellet grill control system. It also explores expansion possibilities of these requirements with respect to user-friendliness. The thesis also includes a description of the system represented by the grill using differential equations and simulations of temperature responses during heating and cooling. After establishing the requirements for the grill control system, suitable components are selected to achieve an optimal balance between functionality and cost. The next step involves the creation of a functional schematic using the KiCad software. A printed circuit board (PCB) is designed and assembled using the components. Finally, the PCB is powered, and firmware is developed to control peripherals.

Automatical plant growing
Stupka, Tomáš ; Dřínovský, Jiří (referee) ; Götthans, Jakub (advisor)
The aim of the thesis is to design and an automated hydroponic station, which will be intended for the cultivation of herbs and vegetables for the purpose of user. The station will be controlled by a Raspberry Pi minicomputer, to which a number of sensors will be connected, which will check pH, EC, ambient temperature and other quantities. Furthermore, an external sensor with an ATMEGA328P control processor will be designed to check the ambient lighting parameters. A web interface will be created for the station, which will allow the user to follow the development of individual measured quantities over time.

Control of the semi-automatic lathe model
Loskot, Petr ; Štohl, Radek (referee) ; Macho, Tomáš (advisor)
The work introduces the concept of conventional lathes. What the main parts are and what the demands on them are. It also brings us closer to the concept of modern CNC machine tools. It presents us with the possibiliteis of motion control in the axes using modern elements and the possibility of position measurement on the axes. In the practical part, the work presents us with some possibilities of components by which the semi-automatic lathe model can be realized.

Cooling system for Industry 4 demonstrator
Cviček, Pavel ; Benešl, Tomáš (referee) ; Kaczmarczyk, Václav (advisor)
The aim of the bachelor thesis is to design and implement a cooling system that will be able to distribute a cooled medium. The individual parts will deal with the description and design of equipment, as well as the selection of components, including electrical ones. It will also include a description of the implementation of the equipment and the control program that will ensure the proper operation of the system. One of the goals is to create a virtual model that will serve for accurate design and also as a check whether all predetermined and required parameters for construction have been complied with. Finally, the work of the system as a whole will be evaluated.

Accelerometer-based monitoring of steering wheel angle
Navrátil, Tadeáš ; Jirgl, Miroslav (referee) ; Mihálik, Ondrej (advisor)
This thesis deals with the design of a device which will be used for measuring the steering wheel angle. Main goal was to design basic concept of device which is using data gathered from three accelerometers in the reconstruction algorithm to get steering wheel angle. Discussion of various reconstruction algorithms (with regards to simulated output noise levels from acceleromater) and final Implementation of reconstruction algorithm (in MATLAB simulink enviroment) is also part of this thesis. Furthermore, thesis deals with the selection of suitable components. Mainly selection of accelerometers, microcontroller and the selection of a suitable communication bus for mutual communication between them. Thesis also deals with design improvements of algorithm and realization of the whole device. In the end, we compare results of measuring device and inner senzor of steering wheel.

Design of a measuring equipment for distance sensors calibration
Zindler, Lukáš ; Sámelová, Vendula (referee) ; Štěpánek, Vojtěch (advisor)
This study aimed deals with the design of a calibration equipment for an inductive distance sensor. The theoretical part provides a basic overview of metrology and the state of knowledge in the field of sensors. In the practical part, several concepts of measuring equipment are suggested, a suitable calibration equipment is selected and assembled, and at last the compensation of the systematic error of the sensor is performed.

Externí systém měření parametrů vozidel s podporou diagnostických protokolů integrovaný v síti ethernet na válcovém dynamometru
Malina, Jakub
This diploma thesis, processed under the name: External system of measuring parameters of vehicles with support of diagnostic protocols integrated in Ethernet networkon a cylindrical dynamometer, deals with the definition of parameter variables that are important for vehicle tests on a cylindrical dynamometer. After determining these variables, a measuring module, which is designed to retrieve data from individual sensors located in the vehicle, is implemented via an OBD II diagnostic connector connected to the vehicle data bus CAN-BUS. The measuring module is integrated into the existing cylindrical dynamometer system at the Mendel University Testing Center in Brno, where the system was tested on a real vehicle.
