Colorimeter
Škoda, Pavel ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This thesis deals with the analysis of the color parameters for their subsequent use in the design of the device, which will be used to measure their stability in continuous production. The theoretical part defines the basic concepts and knowledge needed to understand the problems. In addition, there are described individual components and sensors suitable for color measurement. The practical part deals mainly with the descrip- tion of the construction of the colorimeter, its individual parts and the creation of the control program. At the end, there are results of the testing of the product and their overall assessment

Workplace of flow and pressure measurement
Brabenec, Jiří ; Beneš, Petr (referee) ; Bejček, Ludvík (advisor)
The thesis deals with formation of a workplace for preparation gaseous mixtures and their future usage. The main goal of the thesis is testing of new materials which have suitable usage as catalysts. Gaseous mixture is prepared by calorimetric mass flow meters with control valve and multiposition microelectric valve actuators. The next part describes measuring of pressure and temperature and controlling of furnace temperature. The thesis deals with specifications of all devices, their circuitry, communication and program controlling. All devices are controlled by computer with program which is programmed in LabVIEW.

DCS for building control
Kopeček, Petr ; Beran, Jan (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with DCS for bulding control. The main aim was to develop a general system, which can be adapted according to the individual requirements and which should minimize costs too. Hardware modules, communication bus, communication protocol, system topology and regulation mechanisms, have been designed. Regulators have been set. There are introduced current realization and possible future extensions too. The high security and the high functionality topics are included.

Thermal box - educational model
Gregor, Tomáš ; Houfek, Martin (referee) ; Vlach, Radek (advisor)
This thesis describes the design and production of simple thermal system, which is used as education model for temperature regulation. This education model is called thermal box. Thermal box is controlled by integrated electronics, which is driven by computer I/O card MF 624 and program MATLAB Simulink.

CPU based regulator
Krzyžanek, Jakub ; Macho, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This work deals with construction of regulation apparatus and implementation of PSD regulator into program equipment of a microprocessor. Purpose of this devise is to use the change of motor’s speed to regulate temperature which is measured at the system output. In addition, the work also describes generation of the regulator’s algorithm which is afterwards encoded in C programming language. There is a demonstration of such system in the last chapter.

Design of heating of retirement home
Kouřilová, Klára ; Vyhlídalová, Karolína (referee) ; Horká, Lucie (advisor)
The main aim of this bachelor thesis is design of a heating system of the retirement home. The theoretical part deals with ensuring of thermal comfort and possibilities of building temperature regulation. The second part of this thesis, the calculation part, includes design of panel radiators, dimensioning of heating system, design of hot water preparation and design of heat source. As the heat source is chosen gas condensing boilers for heating system and hot water system. The third part contains documentation for construction of heating system.

Automatic process control of aftercooling in brickkiln
Cacek, Jan ; Ošmera, Pavel (referee) ; Němec, Zdeněk (advisor)
The thesis deals with the design of the multivariable automatic control system of aftercooling process in the brick industry tunnel kiln. Theoretical part submits the facilities of controlled systems identification and the design methods of uni and multi variable systems. In the practical section is cleared up the principal of the aftercooling process and its identification based on the measured data. The output of the thesis is the design and the analysis of multivariable system with the conservation of the control circuit autonomy.

Temperature controller of microwave reactor
Pokorný, Ondřej ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
Simple low-cost temperature feedback control loop was created, using personal computer as control and data acquisition element. It controlled the temperature inside mircowave pressure reactor. Medium in reactor tank (volume about 600 ml) was calorified by 1,8 kW magnetron, which power was driven by PSD controller. The PC- process interface was made by USB data acquisition modul UD128A8D. The utility program was written. It implemented PSD controller and data acquisition function. Furhtermore it implemented interface which enabled user to set the technological curve (time-temperature relation). The protocol of experiment was automatically stored to Micosoft Excel file before the program’s termination.
