Use of the "model based design" method for the design of an embedded application
Mačišák, Martin ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis demonstrates the differences between approaches in software development. A code generation search is performed. The work describes possible tools and methods of code validation and verification. The next part provides information on the use of a design-based model in critical-demanding applications. Further, the work describes the proposal of platforms for controling the BLDC motor. Low leve software is programed for these chosen platforms. The logic of controling and user interface is created. The logic of controling is created and tested in Simulink. Further more whole programmed code is connected with the low level layer. The whole solution of my diploma thesis is tested.

Modernization of the crane education preparation
Machalíček, Kryštof ; Fiedler, Petr (referee) ; Baštán, Ondřej (advisor)
This bachelor thesis deals with the modernization of a crane model used in teaching. The aim of the modernization is to design and implement a teaching control panel according to the existing modular concept of teaching panel, to propose modifications to the electronics of the crane model so that the crane model can be used in a „plug and play“ sense. These modifications will be then implemented on the model. The aim is also to develop a software for verification of the function of all the elements used.

Design of monitoring system for waterworks
Šimková, Jana ; Bradáč, Zdeněk (referee) ; Fiedler, Petr (advisor)
In this work I am trying to find a solution how to design a monitoring system for waterworks, namely for the dam Hracholusky. It includes a schedule of measured values, the way of collecting data to the PLC system with the inclusion of PLC configuration and sorts of communication between between equipments, preparing data for PC, which sort them and prepare them for the next aplication.

Add-on instructions for AS-Interface Network
Grepl, Tomáš ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
This master's thesis deal with design and creating of the instructions for industry bus AS-Interface. These instructions were implemented in the software ControlLogix5000 like add-on instructions. In the teoretical part there are presented the issues of industrial control, AS-Interface bus, add-on instruction and model of the labyrinth. The practical part of the master's thesis is focused to design of the add-on instruction and work with instruction and its characteristics followed by the description of the sample add-on instruction and the list of all implemented instructions. The final two chapters include visualization and laboratory exercise.

Universal platform for measurement of inertial and pressure sensors
Usnul, Jan ; Jirgl, Miroslav (referee) ; Fiedler, Petr (advisor)
Author describes the creation of software for the initial sensor test platform and controll computer. The platform can measure inertial and pressure sensors regardless their specific type. Measurement is provided by automatic test which is defined by the user. Also, the author describes the creation and implementation of communication protocols between control software (on Windows platform) and test platform (embedded C).

Charge controller for solar panel based charging of lead-acid batteries
Korenčiak, Peter ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
Tato diplomová práce se zabývá návrhem a realizací regulátoru pro použití v solárním systému s větším počtem olověných akumulátorů. Takový regulátor umožňuje nezávislé připojení a řízení nabíjení většího počtu akumulátorů různého stáří a parametrů. To je v kontrastu s řešeními obsahujícími jedno připojení pro více baterií připojených paralelně, kde se míchání baterií různého druhu a stáří nedoporučuje. Tento regulátor nabízí vysokou škálovatelnost skladování energie v solárním systému. Umožňuje také používat starší baterie s novými, místo nutnosti staré baterie nahradit, když jejich kapacita klesne pod požadovanou úroveň. V této práci jsou podrobně popsány požadavky, návrh hardwaru a softwaru a implementace regulátoru s nominálním výstupním proudem 20A pro pět 12V olověných baterií. Práce popisuje také další funkce, stejně jako alternativní návrhy a algoritmy. Důležitá část práce se zabývá designem spínačů pro velké proudy, ochrany proti zkratu a obvodů pro měření stejnosměrného proudu. Správná funkčnost regulátoru byla ověřena měřením.

Scoreboard for timekeeping
Večeřa, Jaroslav ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
This thesis deals with reparation and modernization of scoreboard, which was designed by Bc. Róbert Heves in 2007. The first part of this thesis describes principle of scoreboards connection. Afterwards, it describes analysis of mistakes, which had been made and found in construction of scoreboard. It shows redesigned blueprint and describes its realization. This thesis also includes verification of connections functionality, which has been done in laboratory as well as under common conditions.

Module of Analog Inputs with Modbus Communication
Stehno, Tomáš ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This thesis contains the theoretical material needed for practical implementation and design of the Module analog inputs with Modbus communication. The theoretical part describes the Modbus protocol, the shape of the transmitted messages and the implementation of the different types of networks. The practical part deals with his own proposal for equipment and design of the software microprocessor. Hardware part describes the involvement of individual blocks of the product. Software section explains the function of the program.

Control system overhaul of a granulate transport equippment
Minčík, Vojtech ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
This thesis deals with the design and overhaul of the suction system which was part of the extruder dosing device from Reifenheuser. The first part describes the pneumatic transport and its main parts and control possibilities. Moreover, the thesis deals with the evaluation of the original solution of the control system, its advantages and disadvantages, the requirements for modernization from the client and proposals for its implementation. The last part focuses on the selection of suitable components and subsequently on the final implementation of the entire project, which consists of the design of the switchboard, the creation of electrical documentation and PLC programming.
