Electronical irrigation system
Endrych, Václav ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis is concerned with automatic irrigation systems. It describes their purpose their usual fabrication and their individual components, especially electronic controlling units. The goal of this thesis was to construct such unit. Thesis furthermore describes the process of design and realization of this device, starting from determination of the basic requirements on the device, through design of its circuitry and construction, up to design of included control program and final tuning of the device. Resulting controlling unit is functional. It can drive four branches of an irrigation system and measure relative humidity by four independent sensors. Unit offers a number of different functions and is controlled from remote user interface via an Ethernet connection.

Graphics indicator
Dvořák, Roman ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
This thesis is consisting of three parts. In first part was conducted market research and then start preparation concept of project Graphic indicator units using in industrial environment. Creating a basis for continued in making electronic schemes and board. Then the board was made in external specialization company. Then all components were installed. After testing all of function the device was ready for implementation firmware. Firmware was consist of few parts – communication with RS232 protocol, RS485, web interface and last parts is communication with touch display.

Analog input device for industrial automation
Nekovařík, Jakub ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
The main subject of this bachelor thesis are design and implementation of the device, which is used to convert digital values to analog output value in the range 0-10V. This actual trasformation arises in electrical component called Digital-to-Analog Converter. There is a separate chapter, which presents theory and problems of varios types of converts. The following chapters theoretically analyse design of each parts of the device. The conclusion of this thesis deals with specific proposals of used electrical components and a description of the software equipment.

Model of labyrinth
Zbranek, Petr ; Šír, Michal (referee) ; Štohl, Radek (advisor)
This thesis describes the design model of the labyrinth, which is controlled by a PLC and bus system AS-Interface. The introduction provides basic theoretical knowledge of PLC and its bus. The second section describes the characteristics and parameters of the AS-Interface bus. The next section describes the electronic components that are used in the model of a labyrinth. The fourth chapter explains the basics of CoDeSys development environment. The last part describes the software model of the labyrinth.

Sample projects for operator panels
Urbánek, Matouš ; Šír, Michal (referee) ; Zezulka, František (advisor)
In this bachelor’s thesis will learn about the development of exemplary projects that are designed with fixed functionality for operator panels SIEMENS (BASIC, COMFORT, RT). For this task, I have a development environment TIA portal that brings together many software tools and programs. With which allowed me to create code for specific hardware, and communication with him, or in simulation mode to test the behavior of the application in a real environment. Code, on the PLC is required for the platform (PLC) S7-1200. It is modern and provides flexibility in making out our needs in automatik. The task is engaged, firstly synchronization solution PLC and HMI operator panel. Secondly resipes in these panels.

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.

VIZIO - dental system automation
Gábriš, Michal ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
This Diploma thesis deals with creation and realisation of extensions for medical dental unit Vizio. Specifically, it deals with electrotechnical solution and software for capacitive keyboard and with proposal of principle of control and regulation of speed for integrated brushless motor. The Diploma thesis contains both the description of used hardware components, and software solution implemented in assembly language. This device is already in commercial use.
