Connection of Solar Power Plant and Water management
Zajíček, Michal ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
In the bachelor's thesis Connection of Solar Power Plant and Water management the author designs the technical solution of pump control using solar energy. The main reason is to make an automatic system for pumping the rainwater through filters due to increasing its quality. Powering the device with a solar power plant will reduce the energy requirements and will also make it possible to store surplus energy from the solar power plant into the potential energy of the water. The result of the work is the compact device with an automatic control system designed to control small 12 V pumps, theoretical design of the photovoltaic power plant to power the device and theoretical analysis of solar energy and water management issues.

Injection moulding machine prototype
Cikryt, Adam ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This work deals with the design of a prototype injection molding machine for the company Elzaco s.r.o. The work includes theoretical analysis which breaks down injection molding machine into individual components and describes their functionality and their important parameters. Based on the analysis and determination of critical parameters of the injection molding machine, a detailed model of the injection molding machine is created. There are also requirements for electrical components such as motors, power supplies, heaters, temperature sensors, control electronics. The method of controlling such a machine is also discussed.

Technology of product machining on CNC machines
Brázda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.

Measuring cycles in control systems of CNC machines
Hamřík, Jiří ; Jaroš, Aleš (referee) ; Gregor, Lukáš (advisor)
In the first two points, the bachelor's thesis focuses on the comparison of CNC and NC machines and methods of control and programming of CNC machines, a description of the control system of CNC machines from selected producers and the characteristics of measuring cycles. Two producers were selected to describe the technology of measuring tools and workpieces using probes. In the third point of the bachelor's thesis, a practical demonstration of measurements with tool and workpiece probes from RENISHAW is performed. A tool correction was performed followed by measurement of the workpiece with a probe. For statistical evaluation, digital micrometer measurements were added, including comparison and evaluation of the obtained results.

Multi-Way robotic wheelframe
Krsek, Jiří ; Kopečný, Lukáš (referee) ; Šolc, František (advisor)
The master's thesis deals with a theoretical analysis of properties of a multi-way wheelframe and a selection of an appropriate method for the human operator control. Based on the analysis will be designed hardware and software of the control unit for controlling the movement of the robot's multi-way wheelframe. The electronic system will ensure a real-time processing the operator's instructions to control signals for the motors that will drive and implement the required angles of two driven wheels of the chassis. The proposal also reflects a sufficient equipment with input-output channels for any subsequent extension of additional sensors for testing the autonomous robot operation.

Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.
