Automatic control system for the cooling water circuit in the laboratory
KOVÁŘ, Jiří
The bachelor thesis focuses on problematics of feed-back working automatic detection systems. The main aim of the work is development of an automatic detection system, equipped with the water sensors, that should prevent damages caused by unwanted water leak. The system is equipped by sensors, control units, communication module and output switches that enable to activate the alarm, to send the information SMS, close the water pipe and to deactivate water-cooled devices to prevent their overheating. The written part of the bachelor work consists not only of the theoretical background of used components but also describes electrical circuits, schemas and functionality of the system.

Magnetostrictive materials for mechatronics
Rusková, Miroslava ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
The aim of this work is to outline and use or application of magnetostrictive materials and possibilities of mathematical modeling their behavior. Magnetostrictive is the physical character of the material, occurs in the most ferromagnetic materials and leads to many effects. Magnetostrictive materials are more often used to in various branches of engineering.

Pressure and Flow Rate Regulation Design for Pump-Tank System
Kovář, Jiří ; Němec, Zdeněk (referee) ; Svoboda,, Miroslav (referee) ; Březina, Tomáš (advisor)
The proposed work is dealing with control design of pump-tank system as part of broader water-supply network with using of mechatronic approach. The main goal of this work is design of control for regulation of flow, pressure and water level in tank in water-supply network of Vsetin city. This water-supply network consists of various components, such as pumps, pipes, valves, tanks etc. For the purpose of the control design is necessary to create a model of pipe network. The solution of hydraulic analysis is obtained by using the gradient method, which was implemented into the software solution named ADAM. The results of hydraulic analysis are compared with measured values of flow and pressure and difference of these values has to be minimalized by proposed calibration and verification process. The calibration and verification process was implemented in software ADAM. The essence of design control is formulating control problem as optimization problem. Therefore the output of higher control layer is set of procedural rules, which determines for example speed of pumps in time etc. Results were verified by using for this purpose developed computational server (ADAM Server).

Design of test environment for automatic testing of eletronic control unit
Dalecký, Filip ; Andrš, Ondřej (referee) ; Kovář, Jiří (advisor)
This master’s thesis deals with the design and implementation of part of test environment for automatic testing of electronic control unit in the production. The electronic control unit is manufactured by UNIS, a.s. and is used as a control and power electronics for the hydraulic unit. The theoretical part of the thesis deals with the development and automatic testing of electronics in the field of aerospace engineering. The practical part describes the proposed automatic test environment and implementation of testing software using hardware and software products by National Instruments. The main platforms used for software development are LabVIEW and TestStand. Created test environment is finally verified by testing several control units.

A software interface for a laser tracker user application
Kozáček, Peter ; Kovář, Jiří (referee) ; Knobloch, Josef (advisor)
For assembly of product machine is necessary to evaluate a geometric accuracy of individual functional parts of the machine. This process is very demanding and time consuming. One of the reasons of mentioned problems is the lack of software (adaptation) for measuring of the accuracy of geometrical precision. This theses (diploma work) focuses at facilitating the development and creation of own application based on customer requirements and for measuring geometric accuracy with the Laser Tracker AT901 from Leica company. The aim is to create a basic application suitable for measurement of geometric accuracy, which would speed up this process, would be user-friendly, simple and open for further expansion.

Design and implementation of a CANopen communication unit
Řehák, Tomáš ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This diploma thesis describes the design and implementation of an industrial communicator for synchronization and control of electrical drive controllers with the interface of RS232 or CANopen. Hardware of communicator uses the EMX development system by GHI Electronics. Communicator software is implemented in C# by the .NET Micro Framework. Communicator allows user to adjust and control up to four electric motor drives. After a successful connection with each unit, communicator can control its position, which specify the number of revolutions to the nearest thousandth of a turn. Communicator also periodically finds out and displays the current position of the connected units. User operates the communicator with GUI, application instructions are entered via the touch screen or buttons.
