Smart Metering of Water Supply System at Campus of Faculty of Civil Engineering BUT
Černíková, Eva ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The aim of this thesis is to perform an analysis of possibilities and benefits of installing the Smart Water Metering technology at campus of Faculty of Civil Engineering, Brno University of Technology. The main goal was to provide specific solutions of Smart Metering systems from different companies. One part of this thesis is dedicated to a detailed analysis of a water consumption measurement campaign that took place at the beginning of this academic year using dataloggers. Real-time flow rate and consumed volume was recorded every five minutes. Therefore it was possible to determine water consumption patterns during the day and also tell the minimum, maximum and average flow rate in different parts of the campus. Thanks to these measurements, irregular water consumption during the night was observed. This would not have been easily detected without recording real-time data. This system of recording real-time flow rates with dataloggers is considered to be suitable for the needs of faculty. Thanks to a GSM module, recorded values are sent to an FTP server once a day. From there the data can be downloaded to any kind of analysis software. Installation of Smart Water Metering technology at campus of Faculty of Civil Engineering would be beneficial for both operation of the water supply network and also for purposes of an academic research.

Presented diploma thesis is focused on the implementation of Wireless M-Bus protocol to embedded device RaspberryPi with expansion board UniPi. The protocol is implemented in Python with Wireless M-Bus devices communicating via IQRF transceiver connected to the UART bus. The theoretical part is focused on an overview of embedded devices for the IoT, the possibility of their expansion. Further, the UniPi expansion board and Wireless M-Bus transceiver are detailed. First part of the thesis focuses on the Wireless M-bus layers, which provides a basic knowledge for understanding the practical part. The theoretical part concludes overview of captured devices including a description of their data units. In the practical part is the implementation of the sample application for receriving data from a Wireless M-Bus sensors. The application is able to read data from devices transmitting encrypted communication.

Wireless M-Bus communication system
Baštán, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
The thesis deals with the design of wireless communication system using Wireless M- Bus, which works in the 169 MHz band. This system is designed to collect data from meters that are not equipped with a radio and have pulse outputs. The thesis describes the Wireless M-Bus standard and the current components of the communication system used by ModemTec. It also describes the selection and design of a suitable hardware implementing the receiver and transmitter modules and the firmware design for these modules. The thesis deals with the parameterization of the transmitter module in order to specify the parameters of the transmitted measured quantity.

Implementation of M2M Data Generator Utilizing Communication Protocol Wireless M-BUS in Smart Grid Infrastructure
Hudec, David ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
V rámci této práce byl vytvořen popis bezdrátového komunikačního protokolu Wireless M-Bus, zaměřující se zejména na datovou část tohoto protokolu, strukturu jeho informačních polí, režimy komunikace a další specifika linkové a aplikační vrstvy. Na základě tohoto výzkumu byl vytvořen softwarový nástroj v jazyce Java, sloužící jako generátor dat zmíněného protokolu. Pomocí grafického i textového uživatelského rozhraní program umožňuje uživateli vytvořit Wireless M-Bus telegramy s velmi vysokou úrovní detailu a ty následně s využitím některého z podporovaných hardwarových zařízení periodicky odesílat do Wireless M-Bus sítě. Dále byla navržena dvě kompletní řešení, využívající buď samotného bezdrátového IQRF modulu nebo jeho spojení s řídicí deskou UniPi Neuron. Oba návrhy byly zrealizovány, otestovány a jsou v práci detailně popsány.

Analysis of Communication Protocols and Modules in Wireless M-Bus
Holyszewská, Anna ; Neuwirthová, Ludmila (referee) ; Rujbrová, Šárka (advisor)
Cílem této bakalářské práce je nahlédnout do problematiky spojené s rozúčtováním nákladů na teplo a vodu pro jednotlivé bytové i průmyslové objekty. Data jsou nejprve zpracována teoreticky s postupným dělením podle typů měřičů a typů odečtů. Okrajově se text věnuje i bezpečnostním prvkům měřičů, které zajištují ochranu proti úmyslnému poškození ze strany zákazníka i neúmyslnému poškození jako takovému. Dále se práce zabývá základními parametry čtyř konkrétních bezdrátových komunikačních modulů podporující Wireless M-Bus. Srovnání těchto parametrů je znázorněno v tabulce. V neposlední řadě se bakalářská práce prakticky věnuje analýze datových telegramů, které konkrétní měřiče vysílají. Analýza je provedena dle standardů. Hlavním přínosem této práce je lepší porozumění bezdrátovým, dálkovým odečtům měřičů tepla, vodoměrů a rozdělovačů topných nákladů.

M2m Data Generator Utilizing Wireless M-Bus Within
Smart Grid Infrastructure
Hudec, David
Current forecasts predict that the Industrial Internet of Things (IIoT) will account for about 10 billion devices by 2020. Unique, recently unthought of demands are initiating new ideas, particularly Industry 4.01 and SmartGrid networks. In this paper, a newly developed multi-platform software tool capable of testing capabilities of Wireless M-Bus (WM-Bus) networks via simulating sensor-like behavior and communication is presented. As utility companies lack these features, this software implementation and hardware design open the door for initial verification of WM-Bus-based data transmissions without the need to invest money into expensive development and certification where WM-Bus is used for data transmissions.
