Hybrid module for industrial localization
Sedláček, Petr ; Fuchs, Michal (referee) ; Kubíček, Michal (advisor)
Tato diplomová práce si klade za cíl návrh hybridního lokalizačního zařízení, které je schopno lokalizace uvnitř i vně budov. Lokalizace uvnitř budov je dosažena pomocí technologie Ultra Wideband a venkovní lokalizace je provedena pomocí kombinace technologie RTK GNSS a PPP pomocí open - source softwaru zvaného RTKLIB. První část textu se zaměřuje na vysvětlení používaných technologií a výběr nejpřesnější technologie pro venkovní lokalizaci. Druhá část se zaměřuje ma vývoj potřebného hardware a software finálního zařízení a na integraci systému pro venkovní lokalizaci do systému pro lokalizaci vnitřní. Výstupem práce je plně funkční zařízení, které je schopné plynulé lokalizace uvnitř i vně budov. Funčnost celého zařízení je dokázána na finálních testech uskutečněných ve vnitřních i venkovních prostorách. Na závěr také práce zmiňuje možná vylepšení celého zařízení, která mohou být v budoucnu provedena.

Analytical Dashboard for Indoor Locating System
Petrovič, Lukáš ; Ščuglík, František (referee) ; Veselý, Vladimír (advisor)
The main purpose of this work is to create an application which will provide visualisation of historical data from position sensors. The data are being obtained from closed spaces, for example shops, gymnasiums or halls. These data are valuable but without easily usable visualisation they will lose their potential. Right visualisation allows user to better evaluate situation which the data represents. Result of this work is a tool with which the user is able to easily analyse data gained in certain time interval. For the needs of analysis, the application provides various kinds of data representations, which assign the data specific purpose. Data might be presented in graphs for example for the purpose of representation of the total overcomed distance of monitored object. They can also be used in maps which provide good representation of positions due to monitored area. All created visualization elements are put into interactive blocks. These blocks make up almost whole control panel. It is easy to manipulate with these blocks and to edit created visualisation with their help.

Localization Services for Web Applications
Kočan, Tomáš ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
The aim of this master thesis was to develop an application that would visualize the position of sensors placed indoors. Since the sensors are located in the buildings, geographical maps are not used as basis, but the user has the option to upload his own background in the form of floor plans of rooms, floors, buildings,... For this purpose, application has tools for uploading, managing and editing such plans. The paper also describes how to use the application to monitor the current and past positions of these sensors. Support for these features is provided by several server components consisting of a REST server, WebSocket server, Upload servers and other services. Their design, description, and implementation is also part of this document. In addition, the work describes RTLS (Real-time locating system) technology, architecture, client application and data security.

Algorithm Development for Automatic Placement of Positioning System Reference Units
Průdek, David ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This diploma thesis describes designing and implementing the algorithm for automatic placement of the real-time localization system reference units. The algorithm is supposed to work with RTLS of the company Sewio Networks. The content of this thesis covers localization options in sensor networks and it is focused on UWB wireless technology. This thesis defines the use case of the designed feature and the principles of the most important parts for the correct outcome. Furthermore, the thesis contains implementing details and the way of integration into the Sewio RTLS. The last part presents the testing results of the created function and proposes future improvements.

Back-End Design for Analytical Dashboard of Positioning System
Hrivňák, Marek ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis deals with the optimization of the original solution and the design of a new solution for the storage and processing of positional data for the tool Sage Analytics of RTLS developed by Sewio Networks s.r.o. The objective of this study is to find and implement a solution to reduce the production time of Sage Analytics metrics. The optimized original solution provides in a very simple way (without the need to modify the implementation) significant acceleration in the production of metrics (for a time interval of 24 hours of displayed data) on average by up to 503 %. The proposed solution uses the InfluxDB database to store positional data and modifies the data processing in such a way, that it is compatible with the use of a new method of storing and retrieving positional data. The new solution also includes tests to check the correctness of the proposed solution. The application of this solution brings acceleration in the production of metrics (for the time interval of 24 hours of displayed data) from 725 % up to 2085 % and on average up to about 1010 %. Part of the work is also the performance of several experiments, which aim to reveal the reasons for the duration of metrics in Sage Analytics.

Platform for Interactive Exhibitions Based on Current Position
Čonka, Filip ; Kreslíková, Jitka (referee) ; Bartík, Vladimír (advisor)
This thesis focuses on the development of interactive exhibitions web application based on the current indoor position. The application is independent of a specific backend implementation and uses modern web development technologies. This thesis deals with deployment using cloud computing technologies. I implemented the application with the use of the frontend JavaScript framework Vue.js. As a data source, there is a PHP backend with the REST API based on the Laravel framework and the October CMS. I use the RTLS technology of the company Sewio. The application runs within Docker containers. I created a platform which brings interaction with the consumer and provides additional useful information about the presented exhibits. Galleries and museums can use enhance the attractivity of their exhibitions based on this application.

Spatial Identification Methods and Systems for RFID Tags
Povalač, Aleš ; Carvalho, Nuno Miguel Gonçalves Borges de (referee) ; Polívka,, Milan (referee) ; Šebesta, Jiří (advisor)
Disertační práce je zaměřena na metody a systémy pro měření vzdálenosti a lokalizaci RFID tagů pracujících v pásmu UHF. Úvod je věnován popisu současného stavu vědeckého poznání v oblasti RFID prostorové identifikace a stručnému shrnutí problematiky modelování a návrhu prototypů těchto systémů. Po specifikaci cílů disertace pokračuje práce popisem teorie modelování degenerovaného kanálu pro RFID komunikaci. Detailně jsou rozebrány metody měření vzdálenosti a odhadu směru příchodu signálu založené na zpracování fázové informace. Pro účely lokalizace je navrženo několik scénářů rozmístění antén. Modely degenerovaného kanálu jsou simulovány v systému MATLAB. Významná část této práce je věnována konceptu softwarově definovaného rádia (SDR) a specifikům jeho adaptace na UHF RFID, která využití běžných SDR systémů značně omezují. Diskutována je zejména problematika průniku nosné vysílače do přijímací cesty a požadavky na signál lokálního oscilátoru používaný pro směšování. Prezentovány jsou tři vyvinuté prototypy: experimentální dotazovač EXIN-1, měřicí systém založený na platformě Ettus USRP a anténní přepínací matice pro emulaci SIMO systému. Závěrečná část je zaměřena na testování a zhodnocení popisovaných lokalizačních technik, založených na měření komplexní přenosové funkce RFID kanálu. Popisuje úzkopásmové/širokopásmové měření vzdálenosti a metody odhadu směru signálu. Oba navržené scénáře rozmístění antén jsou v závěru ověřeny lokalizačním měřením v reálných podmínkách.

UWB Locator
Jančiar, Marek ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
The subject of this work is the implementation and evaluation of the parameters of the localization system using UWB technology. This work focuses on two localization methods, namely TWR and TDoA. To compare the capabilities of UWB with other wireless techno- logy, this work also includes an implementation using BLE technology, specifically a method that uses the RSSI value. Parameters such as the accuracy or energy consumption of the implementation of these methods on specific hardware were practically measured and in- corporated into the text of this work. With the help of this work, the reader can create an image of the capabilities of the mentioned technologies and the way of implementing the localization methods.
