Automatické řízení a monitorování ústředního vytápění pro starší budovy / Automated Control and Monitoring of Central Heating for Older BuildingsMužila, Matej January 2019 (has links)
The purpose of this thesis is a design of an automated heating regulation system for an old building. The thesis consists of a system architecture design, an implementation of the system, including prototype manufacturing of the required devices, and testing of the whole system in practice, with focus on functionality and efficiency. Several hardware devices were designed and manufactured, for which appropriate controlling software was implemented. The implemented software architecture enables users to control the system using a graphical user interface, and allows for an easy extension of the system. The graphical user interface, which is accessible both locally through a touchscreen and remotely using a web application, enables users to easily configure connected devices and regulated zones, and to set temperature level in the defined zones variably depending on a week day and time. The user interface also provides statistics about the heating system. The implemented automated heating regulation system was successfully tested in real conditions of a flat in a historical building. The system can be extended both hardware-wise and software-wise.

Návrh zařízení pro měření střední teploty proudícího vzduchu v kanále libovolného průřezu / Design of device for determination of air mean temperature in the channel with various crossectionTichý, Vojtěch January 2019 (has links)
Diploma thesis was dealing with design of the device for measuring the mean temperature in a channel of any cross-section. First, the theory of heat, heat transfer and fluid flow was summarized. Theory was focused specially on the uneven temperature distribution in the flowing medium. Furthermore, a general overview of commercially used temperature sensors and developed sensors with applicability to the investigated problematics was elaborated. Then, a device for sensing mean temperature in a flow channel for several different diameters has been fully designed and developed. The device included the temperature sensor itself, the necessary measurement electronics and its programming, and a simple measurement data application.

Optimalizace a měření transportních experimentů na grafenových polem řízených tranzistorech / Optimalization and measurement of transport experiments on graphene field effect transistorsUrbiš, Jakub January 2019 (has links)
This thesis deals with the automation of transport experiments on graphene using the graphical programming language LabVIEW. Specifically, the experiments with graphene relative humidity sensors are based on: a two-point graphene structure, a two-point structure of SiO$_2$ and a four-point graphene structure in the form of a Hall bar. In all of these experiments, relative humidity, input electrical parameters, SPM measurements, and macroscopic transport properties are measured simultaneously. The program DeviceManager developed in framework of this thesis simplifies the implementation of these experiments.

Měření velmi malých výchylek pomocí optovláknového interferometru / Measurement of very small displacements with fiber-optic interferometerVybíral, Dominik January 2020 (has links)
This master's thesis is focused on optical methods of measurement of very small dynamic displacements. Principles of interfermeters with picometer resolution including Fabry-Pérot interferometer are discussed and an integration using this interferometer was designed. Parasitic influencers of Fabry-Pérot interferometer were described as well as signal processing methods for interferometer's output signal. An interferometric meter for measurement of dynamic displacement was designed with frequency range of several kHz. These parameters are achieved under condition of photonic crystal layer placed on measured sample.
