Motor controller UMC100 training device
Janáček, Martin ; Vaněk, Jaromír (referee) ; Dohnal, Petr (advisor)
Bachelor’s thesis conserning motor controller UMC100-FBP by ABB s.r.o. shows usage possibilities of this technology for 3-phase asynchronous motor. For demonstration was laboratory task designed and developed. It shows serious defective states of motor in practice. Construction plan and electrical diagram were made in AutoCAD and Inventor Professional.

Electronic notice board LCD
Chmelař, Petr ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This paper focuse at market research with digital signages, kiosks, and the subsequent suggestion directed on the concept of the new system and its hardware parts and software. The aim of this work is grounded on creating the concept of electronic boards, which is derived from the market research. The concept of the system is describing the principle of functioning of the digital signage, possibilities of controlling and system administration itself. The suggestion of the hardware part of the system contains the selection of appropriate mechanism for realization of the software part of the system and the proposal of controlling and signaling aspects, which are suitable for communication with users.

Control Panel with Touchscreen
Nevoral, Jan ; Crha, Adam (referee) ; Musil, Petr (advisor)
The aim of this work is to design and construct a printed circuit board with touchscreen connection that will serve as a universal platform for controlling a variety of devices including industrial devices. The functionality of the board is demonstrated on control of gas boiler application. The first part attends to currently used and available graphic displays, touchscreens, communication interfaces and microcontrollers that allow control of a graphic display. The main focus is put on LCD TFT displays, resistive touch panels and microcontrollers with LCD TFT controller. The second part describes the selection of system components, design of printed circuit board and implementation of thermostat. The end of the work evaluates the produced device and discusses possible future extensions.

Optimalization of Induction Furnace Operation in foundry Vsetín
Trachta, Jiří ; Nowak, Stanislav (referee) ; Lázničková, Ilona (advisor)
The aim of this work is optimalisation of induction furnace in foundry for company PROMET FOUNDRY a.s. The company has two induction furnances. There are installed as identical construction. They have 2 modes of operation. First mode is founding and second mode is mode, where is temperature in maintain mode. Only one induction furnance can work in the founding mode at a time though. Inducion furnances are in the single-phase connection and they cause unbalance in the distribution network. Near the foundry there is a small network area whitch it is operated by company Zásobování teplem Vsetín a.s. The consumption of electrical energy in foundry so big, that in the year 2009 was made elaborate for Zásobování teplem Vsetín a.s. It was write at Laboratoře diagnostiky výkonů (Laboratory of performance diagnostics), which is a part of Electrotechnic Department at Technical Univarsity of Ostrava. The ordered study was named “Verification of causes of increased reactive energy consumption during transition from electricity delivery to electricity consumption”. The conclusion of this assignment confirms that in distribution network in the Jiráskova area in Vsetín there is unbalance of electrical energy and there is high part of reactive power. The next conclusion is crucial to find the customer who made the unbalance and to set relevant remedy. The last step will be the identification whether such device can actually be effectively balanced. It was subsequently proved that the Promet Foundry was causing the unbalance and that balanced consumption would be reasonable. Promet Foundry thus addressed Autel a.s. company with an inquiry to make a study of removing the causes of the unbalance which is caused by current induction furnaces operation at a minimum possible cost, least possible influence on the performance and minimum construction changes concerning the building. In this thesis there will be some topics. The result of which will be introducing of used heating technology, introducing of company and of effective plant performance and subsequent suggestions of possible unbalance removal or reactive power decrease. Several ways which are being implemented in the industry in order to balance consumption will be described. A suitable balancing plant will be subsequently chosen and its parameters will be calculated.
