Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.

Using the infrared camera in the measuring technique
Bayer, Robert ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
The goal of this thesis is to get acquainted with contactless methods of measuring a temperature and give the reader an idea of it. Next goal is to master the working with IR visual display terminal FLUKE Ti55FT (and program equipment SmartView) a describe it to the reader too. Last goal is to translate the booklet "Introdution to Thermography Principles", published by FLUKE company, which will be enclosed in electronic form to the thesis in the appendix.

Thermal imagers in technical diagnosis
Haltuf, Martin ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
In this thesis is dealed the technical term diagnostic with Fluke Ti55 thermo imager. In the introduction of description is analyzed noncontact temperature measurement including principle, uncertainties measurement and measurement system. In other parts of the work is focused on thermal imaging, termogram, description Fluke Ti55 termo imager and measurement of mechanical stress. The concluding part of the description and processing of measurements, including their evaluation.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.

Measurement of thermal field in electric machines
Dostálek, Martin ; Vítek, Ondřej (referee) ; Janda, Marcel (advisor)
Diagnosis temperature is one of the most important disciplines. We meet it in everyday life, but it is very important for all sectors of industry. This is a measurement providing an immediate state of the measured object. Contact measurement of different temperature sensors and contactless measurement using thermal imagers. The important part is the measurement of temperature rise of induction motor. Part of the work deals with losses in the electric motor. These losses are converted into heat, which affects from various parts of the machine. Correct identification of the temperature field is important in helping to design the cooling system of the instrument. Virtually the data obtained are compared with theoretical data. We will capture part of the device and realize thermal simulations in a suitable simulation program. We propose modifying the cooling machine and the resulting data from the simulation compares.

Methods for infrared thermography with detection of specific facial areas
Kolářová, Dana ; Bernard, Vladan (referee) ; Maryšková, Věra (advisor)
This paper deals with non-contact measurement of temperature in human faces. Principle of measurement of infrared radiation and construction of the thermal imager is described in a literature search. The main part of the paper is design of an algorithm for automatic processing and the detection of regions of interest in thermal images. The theoretical description of used methods is also included in this paper. The aim is to design and implement a program for automatic evaluation of temperature changes in a human face in a sequence of thermal images that were taken with short time delay. As a part of thesis is description of implementation of designed algorithm in programming enviroment MATLAB and the description of the user interface. The program was tested on the experimental data samples. Obtained results and possible limitations are also discused in this paper.
