From a Dumb Boiler to a Smart One Using a Smart Socket
Mitura, Jacek ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
Nowadays, the world of smart devices is growing very fast. Nevertheless, it remains difficult to acquire smart device for water heating applications. The usual reasons complicating this fact include the lack of the possibility of connection to the central control unit, or the need to replace the entire boiler with a new smart model. In both cases, the additional disadvantage is the higher price of such a solution. Therefore, the aim of this bachelor's thesis is to create a comprehensive and affordable solution, ensuring the conversion of an existing boiler to smart using a smart socket and a central server controlling the household. The solution uses a daily consumption forecast based on an exponential moving average to save electricity.

Module for data collection from industrial equipment
Vávra, Petr ; Kaczmarczyk, Václav (referee) ; Fiedler, Petr (advisor)
Theses deals with development of a module for data collection from industrial equipment. As a suitable protocol for collecting data is chosen OPC UA. The source of data are OPC UA servers on PLCs from Siemens. For secure transport to public cloud Microsoft Azure over TLS protocol is used IoT Edge and IoT Hub gate. The data are stored in Time Series database InfluxDB. For visualization are used web applications Influx DB and Grafana. Software is tested on industrial equipment.

Management and Automation of Enterprise Facility Heating System
Hartmann, Jiří ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
The aim of this work is to create a unified control and supervision system, SCADA, for controlling the heating and cooling of the company. The system is controlled by UniPi PLC units. Node-RED is used as control software. The user interface is created by an extension "dashboard". For communication between elements using the MQTT protocol. The InfluxDB database is used for data storage. The Grafana tool is used to visualize historical data. The majority of the created system consists of open software. The system is universal, expandable and it is possible to connect it with another system. The system can be used or adapted to similar problems of advanced heating control.

Well Water Level Measurement
Samek, Jakub ; Košař, Vlastimil (referee) ; Korček, Pavol (advisor)
This thesis deals with the well water level measurement. The main aim was to design and construct a device using proper platform and sensorics for measuring which is used for measuring the water level in the well. This device uses batteries. The expected battery life is several months. The device sends collected data via network to the server. These data are visualised in graphic interface using a graph. The system controls the water level in the well and battery level of the device. When the limit values are exceeded, the user is notified by e-mail. Based on this information, the user can decide how to be economical with the water.

Automated area measurement of precipitation intensity via a network of microwave links
Bubniak, Milan ; Pospíšil, Ondřej (referee) ; Musil, Petr (advisor)
Point-to-point microwave links can be utilized as a large sensor network to measure rainfall. This work deals with the application of this procedure in practice. The first part of the thesis deals with atmospheric precipitation in general and standard methods of their measurement; and the propagation of the microwave signal and various causes of its attenuation, focusing on the attenuation caused by rain and the recommendation ITU-R P.838. This is followed by a state of the art summarization of the measurement of rainfall by microwave links. In the second part of the work, a manual procedure for calculating rainfall from microwave link data is performed, taking wet antenna attenuation into account. Then the creation of a support tool in the C# language is being described, which supply the data to the functions of the RAINLINK rainfall calculation library. Several rainfall calculations that are validated by physical rain gauges are performed. Furthermore, the own Telcorain application for rainfall calculation is created in the Python language, based on the pycomlink library. It has a graphical user interface created in PyQt. Several rainfall calculations validated by rain gauges are performed again, and the results are compared with the RAINLINK library.

Smart Home: Digital Thermostatic Valve Controlled via WiFi
Smejkal, Jan ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
This bachelor thesis deals with smart home heating in households with radiators. The goal is to design a cheap digital heating head and to integrate it via WiFi and MQTT into the Home Assistant system. I have focused on keeping good design, head functions and a good user experience. Home Assistant enables showing graphs using InfluxDB and Grafana. Using a program in tool Node-RED enables it to lower heating temperature at the times of user absence and to schedule heating temperatures. The price of the complete unit is under 400 CZK. Temperature regulation was provided by a prediction controller, but it was replaced by a PID controller. The controller can regulate with the difference of maximal and minimal temperature of around 2 C. The user can control the boost mode of the head via a physical button or using the Home Assistant system. The resulting product is a good basis for a low-cost smart heating system.

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.

Application for early detection of transmission parameters degradation of microwave units
Bubniak, Milan ; Benedikt, Jan (referee) ; Musil, Petr (advisor)
Radio equipment of microwave links operating in an outdoor environment under the influence of weather conditions is at risk of a link failure or device defect occurrence, as well as their indoor units. This bachelor thesis aims to present the creation of a~network monitoring application capable of timely detection of potential failures, based on analyzing trends in monitored device parameters. The theory section deals with basic characteristics of microwave links and the structure of Simple Network Management Protocol. The practical section describes an application design, including core architecture, as well as a graphical user interface. Several failure detection methods are designed and described. In the next section, practice monitoring results are presended. Furthermore, network traffic and data storage requirements are measured. The conclusion summarizes the results of the application development and outlines it's future with new possible features.
