A multi-source power station switch- and control-boards digitization project
Fiala, Martin ; Bátora, Branislav (referee) ; Drápela, Jiří (advisor)
This bachelor´s thesis deals with comprehensive proposal and reconstruction of switchgears for source power station on Department of Electrical Power Engineering with controlled rotating and static power sources, that can be managed remotely using a programmable logic controller via the communication link. Part work also description of the control system and all the necessary parts for reconstruction. At last this thesis deals with the problem, which is linked to the deployment of automation in general, including the negative aspects, describes the problem of industrial communication systems along with the most used fieldbus that is used in the implementation of automated solutions.
Measurement of the rain rate instantaneous value using acoustic method
Kresta, Daniel ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This thesis deals with implementation of the rainfall rate measurement using an acoustic method. It is divided into four parts. In the first part of the thesis a necessary theoretical knowledge is analysed. The second part contains a design of a workplace used for the measurement. The third part presents and analyses important experimental recordings acquired in the workplace. Then all measured values are processed and applied in the measuring program. The last part summarizes results of the thesis, advantages and disadvantages of using the acoustic rainfall rate meter.
Current sensor with digitized output signal
Hanuš, Ivan ; Vágner, Martin (referee) ; Havránek, Zdeněk (advisor)
The objective of this thesis is to describe principles of measuring of alternating current in low voltage power supply network with Rogowski coil and to study details of requirements for electronic current sensor with digital output. Furthermore to study the current solution of digitalization of output signal from Rogowski coil and to determine metrological characteristics of the digitalization module for processing the signal from the Rogowski coil as current sensor and to design a concept of an electronic current sensor unit with Rogowski coil and the digitalization module with the expected optical output. The theoretical part deals with the measurement of current using Rogowski coil, its characteristics and advantages compared to conventional current transformers. Further in the thesis there are specified the requirements for current sensor. The practical part deals with the design of digitalization module consisting of a pair of AD converters, a microcontroller and output circuits. Furthermore, the thesis deals with digital signal processing of signal from Rogowski coil. Furthermore, the thesis describes firmware for microcontroller and PC application. The result of thesis is functional circuit of electronic current sensor that processes signal from Rogowski coil and converts it to digital form.
Design of Portable 3D Scanner
Štigler, Jaroslav ; Rubínová, Dana (referee) ; Sovják, Richard (advisor)
The topic of this bachelor‘s thesis is design of handheld 3D scanner. This scanner belongs in the higher price category. This thesis deals with problems like long working time, watching monitor during scanning, versatility and safety measures from mechanical damage. Ergonomic solution is also very important. This design is based on a simple and functional shaping. Shaping and color solution corresponds with its use in industry. This scanner also can be used in other fields (for example: medical sector, design, archeology, etc.).
Ancient Maps Digitizing
Pospíšil, Josef ; Šilhavá, Jana (referee) ; Španěl, Michal (advisor)
This work is about processing of historical maps, especially their digitizing and vectorization. The main focuses of this project are maps from the second historical military mapping and finding methods useful for removing texts from these maps.
Determination of efficiency of hydraulic drive with recuperation
Kobza, Michal ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
In the first part of the thesis is determined efficacy criterion for the individual operating modes of the experimental stand with energy recovery and subsequently are evaluated the records of individual measurements. Energy savings are calculated with using energy recovery. The second part describes the process of digitizing relative fuel consumption map of the engine. Results are confronted with a real application engine in the road roller Ammann AP 240 H. In addition, the master thesis describes the creation of hydrostatic converter block in the program MATLAB/Simulink 2012b. Creating block can be used in the development of simulation models.
Using 3D Scanning for the Preparation of Steam Turbines Cast Parts for Machining
Michalisko, Jan ; Sedlák, Josef (referee) ; Madaj, Martin (advisor)
The technical paper deals with the application of 3D scanning for the preparation of cast machining which is a part of steam turbines manufactured by the Industrial Turbo machinery branch office of the Siemens Ltd. in Brno. There is a theoretic explanation of general terms which relate to the 3D digitization process in the first part. Further in the theoretic part, the used digitization systems TRITOP and ATOS are described in detail. In practical part, the analysis of the current process has been carried out and the alternate process of the cast preparation for a subsequent machining has been suggested. By means of above mentioned systems, the cast has been converted in a digital form and compared with the source CAD module. The comparison results in material allowance check and the suitable setting for a following machining process. In conclusion, the technical economic evaluation of both processes has been carried out.
Manufacturing technology of a car copy by digitizing method
Eis, Jiří ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
This thesis, maked as diploma project at VUT Brno, summarize in teoretical part most used methods, technology of reverse engineering and rapid prototyping, including their using in practice. Experimental part discussed about aplication of this technologies on practical example. Tendency of thesis was creation of digitized model of a car by optical scanner ATOS and photogrammetry system TRITOP, including modifications and processing of get data, which will use to verification of model by FDM technology.
Digitalization of ultra-light plane fuselage for production of accurate mould
Véle, Filip ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
This work describes digitalization and creation of ultralight aircraft 3D model in order to create accurate moulds for fuselage lamination. Right choice of technology is based on background research. Designed procedures are described in detail as well as used equipment, hardware and software. Objective of this project is application of available methods of digitalization to create 3D aircraft model and its usage for accurate mould design.
