Machine tools safety
Smetana, Štěpán ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
This Master’s thesis concerns about the safety of machinery, in the literary research part you can find information about the law system and requirements of European Union and Czech Republic. There is a description of the legal enactments, which the manufacturers of machinery needs to follow. Second part of this thesis is about the safety of a milling center. The milling center is analyzed here, you can find here the description of its components. The milling center was then described with the help of block diagrams. For each component from the block diagram you can find here a list of dangerous situations which can occur and also a list of safety precautions for each situation. Based on these information the list of requirements for the milling center was made.

Programmable IR receiver
Géze, Daniel ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor thesis is design and realization of solutions for hardware and software programmable IR receiver. IR receiver is actually a logic programmable automat, which responds to commands from the remote broadcast communications protocol RC6 designed by Philips. Codes of these commands can be assigned to different actions. Using the configuration application in PC by any code of buttons it is possible to order firmly programmed codes in a flexible management processor Cypress (CY8C29466). Configuration software for the PC has been created by using the python programming language. The main purpose of this device is helping for the handicapped people.

Optimization of manufacturing process in a selected company
Koníček, Jan ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Bachelor thesis is dealing with optimalization of manufacturing process in engineering company Kovokon Popovice s.r.o. First part is fucused on streamlining of material flow by using circular method and triangulation method simple, from which there are three variants of workplace layouts and the most advantageous one is selected. In the next phase of optimalization, a block diagram is compiled for original prodiction and subsequently for the modified one by using machining center replacing previous machines. Capacity calculations are then calculated for the block diagrams, which express percentage use of workplace and numbers of workers needed to produce selected component. In the last part of optimalization, the requied size of the central material werehouse, number of cranes and forklifts are calculated.

Mechanical manipulator controlled from the cRIO platform
Karásek, David ; Šedivá, Soňa (referee) ; Havránek, Zdeněk (advisor)
This bachelor thesis is about designing and creating control software for 2 D mechanical manipulator. This device consists two translational actuators and one rotational actuator. At theoretical part author discuss possible hardware solutions and talks about basic terms used in practical part. Practical part is about designing main control application. Final program is fully functional, at the end of this thesis the author suggests some improvements which could be done to the program.

DSP56800 microprocessor line usage for asynchronous motor control
Kukuczka, Adam ; Huták, Petr (referee) ; Klíma, Bohumil (advisor)
Tato diplomová práce pojednává o možnostech simulace a modelování elektrických pohonů na základě Bondových grafů. Je zde uvedena základní teorie k problematice. V práci jsou představeny modely stejnosměrného a synchronního stroje sestavené touto technikou. Dále je zde seznámení s Freeware knihovnou Bondových grafů BG V2.1 k programu MATLABSimulink. Za pomocí této knihovny byly sestaveny oba modely strojů. V poslední kapitole je uvedeno srovnání modelování na základě teorie Bondových grafů s modelováním v blokových diagramech.

Measurements of the DVB-T Digital Television Receiver
Kobza, Jaromír ; Džubera, Jakub (referee) ; Kratochvíl, Tomáš (advisor)
This thesis is focused on a receiver for digital television broadcasting set-top box, mainly on its features, parameters and measurement. The important point of this work is the possibility to analyze and visualize the parallel transport stream in the same time and the solution of this problem. The principle of tuner and its measuring is deeply discussed. The text is supported with oscilloscope screenshots in particular parts of decoding stream. The set-top box is modified for laboratory measurement purpose and the transport stream output is added. An example laboratory exercise was created as a part of this work.

Creation of LabView application for automatic measurement of switchgear temperature rise
Kopunec, Vít ; Huzlík, Rostislav (referee) ; Valenta, Jiří (advisor)
The aim of this work is to create an automated measurement of the temperature increase of electrical devices using the graphical programming environment of LabVIEW. To measure the temperature increase, up to four thermocouples are used of any type. The final .vi file must meet the requirements for the particular option settings; before running a measurement. On the front panel .vi file, is displayed the following configuration elements: time measurement, number of measurements, thermocouple type and amplification. The programme measures the voltage of the thermocouples, recalculates the value of voltage to the temperature, measures the values to write to a file with a txt extension, and writes values into the tables, constructing useful graphical information of physical measurements.
