Model of CNC milling machine
Kovář, Pavel ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
The master's thesis deals with the basic parts and principles of CNC machines with a focus on a CNC milling machine. There are also comparisons of several CNC machines sold. Furthermore, the project deals with the description of the manipulator, which is situated in laboratory E-132 in area Kolejní 4, Brno. The work also includes a description of the device, which is located in the manipulator model. We can find there a description of the program generating G-code from the image that you create in the editor. The next section describes possible modifications of the manipulator for its reconstruction on a CNC milling machine. The last chapter deals with the description of program developed for controlling the manipulator as a CNC milling machine.

Control system for laboratory distillation column model
Chlad, Petr ; Šír, Michal (referee) ; Štohl, Radek (advisor)
The aim of this master’s thesis was to create a control system for laboratory distillation column model. There are two different models considered. Real and software model. For the real model suitable components were selected and the model was built. Software model allows safe testing of control algorithm functionality without the need of real model. The simple visualization that works with both models was developed. Both distillation column models - real and software - were tested as a last phase of work.

Multiple-funktion steering wheel Formule Student
Paulus, Luboš ; Štohl, Radek (referee) ; Havlíková, Marie (advisor)
The Master‘s thesis deals with a creating of display writers on multiple-function steering wheel Formule Student. It is mainly about dates transfered through RS232 or CAN bus from control unit of the Formule to microcontroller. First of all it is necessary to find out, which informations and a which way of displaying them are more useful and readable for drivers. This leads to another point - right choice of display writers, which will be used on the steering wheel. Creation of the design and construction of display device follows.

Control of lift model
Žůrek, Martin ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
My graduation theses is focused on project of algorithm proceedings laboratorial model of a lift and visualization in computer program Factory Talk View Studio. In introduction is written about industrial comunication network AS-Interface and in practise used algorithm proceedings of a lift. In following capitol is described system and several parts of laboratorial model of a lift. Not least is solved also comunication among floors of a lift, cabin and master AS-Interface and project of functional block in computer program RSLogix 5000. General purpose of master’s theses is project algorithm proceedings of a lift which use double-sided collecting proceedings. In last chapter is noticed project of visualization, which control a lift.

Laboratory stand with RABBIT CPU
Váša, Tomáš ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This master’s thesis contains design of laboratory stand for learning programming microcontrollers. Stand is equipped with two Rabbit modules, which are connected together over local area network. Exercises are focused on working with basic peripheries as digital inputs and outputs,PWM modulation, serial communication. Exercises are interested in evaluation of matrix keyboard and communication with alphanumeric display controller. With the ability to easy access the Internet some exercises are designed for work with this interface. To these exercises is made a preparation of external peripherals. Through these peripherals there can be can be controlled DC motors, step motor, binary outputs and inputs. Each lab exercise contains an introduction, task, instructions and the flowchart of realized exercise. Instructions are written so that it contains important steps to properly manage assignments. Individual exercises are designed to gradually increasing complexity of exercises.

Industrial state indicator
Zamrzla, Martin ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with study of materials needed for proposing and implementation of the industry state indicator. In the theoretical part there are describe all used components including calculations. Then there is a description of the communication interface used on the indicator. The theoretical part is then followed by a description of MODBUS protocol. The practical part is divided into a few sections. First one decribes the implementation itself together with the idicator activation. Second one describes the programme equipment of microcotroller. The conclusion is about description of the application testing.

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.

Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.
