Power Line Communication for Home Automation Applications
Hromádka, Michal ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
This thesis describes the design of a modem for a communication over residential power lines. First part is focused on the history, suitable frequency bands, modulation techniques and mainly on the selection of the optimal modem device. Second section contains the description of the hardware design of the modem itself and clarifies the implementation of the PLC module to be used as a communication interface for a full residential automation solution. Last chapters of this thesis introduce the communication protocol, design of the software for the ATmega32 MCU and present of the final field testing under real conditions.
Design of PLC network for remote data acquisition
Šebela, Miroslav ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
In thesis is according assignment realized PLC (power line carrier communication) network design for remote data collection. To understand problematic of PLC is this technology described little bit in detail. In thesis are mentioned possibilities use broadband and especially narrowband power line carrier communication. Described is also general structure of PLC network for data collection - automatic meter reading. Finally is described realization of PLC network on chosen area included component supplier selection. In thesis is also mentioned problematic of PLC a communication channel included problems with noise and channel impairments. With selected PLC modems was realized and evaluated measurement of communication speed in different environments and with use of different interfaces. Furthermore was measured spectrum of communication signal from which was possible to define signal modulation. In last step were measured impairments in powerline.
Power line grid model
Csiba, Patrik ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This diploma thesis analyzes the PLC communications in various scenarios. The first part of the thesis describes the principle of narrowband and broadband communication and the analysis of electrical lines. The next part describes the NS-3 framework, simulation scenarios for establishment the effect of branches and other parameters on the baud rate. The last part determines the minimum number of repeaters and their location on the extended topology.
PowerLine Communication for LED unit control
Šebesta, Ondřej ; Janáková, Ilona (referee) ; Honec, Peter (advisor)
This diploma thesis deals with the design and testing of a system for powerline communication, enabling control of LED lights. The work first describes the basic principles of powerline communication, specifies the communication bands and summarizes the basic functional requirements for communication within the system for LED lighting control. It also describes the method of selecting a modem for powerline communication, the design of a test module with this modem and also the method of testing real communication between two test modules, including test results. The most comprehensive part of the work describes the design of hardware and software of the universal PLC module and how to use it. In addition, it referes to the development tools used as an example of implementation in LED lighting. At the end of the work are summarized the results of testing the proposed system.
Communication unit for intelligent home appliances
Čičmanský, Tomáš ; Koutný, Martin (referee) ; Mišurec, Jiří (advisor)
Bachelor’s thesis is devoted to clarify the issue of PLC. The main task is to gather the necessary theoretical knowledge about PLC, which will be then used to design functional narrowband modem. It will interact with and manage devices connected to the network and use appliances, sensors and other devices in the so called smart house. This project is made particularly with regard to price, availability and final device parameters.
High Data Rate Narrowband PLC Communication based on OFDM
Csiba, Patrik ; Herencsár, Norbert (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communication. In this project is described history, principle of narrowband communication and description of four available narrowband standards (PRIME, G3-PLC, G.hnem, IEEE P1901.2) with their comparisons. In the next part are described the experimental measurements, that are performed in home environment with use of the TMDSPLCKIT modems from the Texas Instruments company, MT39-L1-ver.R modems from the ModemTec company and EVALKITST7580-1 modems from the STMicroelectronics company.
Narrowband PLC communication for Smart Metering
Kubů, Jiří ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communications. The work describes the basic principle, division of PLC communication, history, technology, utilized communication standards and interference affecting the data communication technology. In this work we also performed experimental measurements in real environments with modems from Texas Instruments C2000 and C2000 TMDSPLCKITV4 PLC PLC TMDSPLCKIT-V3. The results of the measurements are real transmission rate. Moreover application was created for remote data collection along with PLC modems C2000 PLC TMDSPLCKIT-V3, the aime was to edit PLC modem firmware and create applications for receiving data from the terminal.
Modem for powerline communication
Sláčik, Ján ; Mlýnek, Petr (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis is dealing with the standards and usable circuits applications for a powerline communication, which are currently available. Principle of this kind of communication is described for default supply network 230 V/50 Hz. This work is also describing several available modems which can be used for this type of communication. The properties of the standards PRIME and the G3-PLC, which are presently at disposal, are specified, measured and compared with each other in this project. The concentrator based on the G3-PLC standard extended about radio interface was designed. Afterwards this device was tested in various topologies and interference scenarios. The graphical interfaces, which allow the transfer measurements in multiple modes are described is this work as well. The entire measurements were realized in a real conditions for both tested modems. The results of these measurements are validating the purpose of each standard and its configuration.
Narrowband PLC modem
Novák, Pavel ; Koton, Jaroslav (referee) ; Mlýnek, Petr (advisor)
The theses is focused on the use of PLC technology. The aim of the thesis is creating device which communicates in a narrowband transmission frequency band. Transmission of communication between plc elements runs through the low voltage distribution network. The frequency and phase modulations are used in order to change the character of data signal. Transmitter and receiver parameters are subjects to the CENELEC standard. The theses gives more attention to the area of hardware build communication element rather than the area of programming.
SW for configuration of PLC modems
Tichý, Vojtěch ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
The aim of this bachelor thesis is to design an application for easy configuration of modems, from ModemTec, communicating over power lines. The bachelor's thesis first deals with a brief explanation of the communication over the power line, which will give the reader a general idea of what the application will be used for. Furthermore, to understand the meaning of the individual adjustable parameters of the modem, the serial port is explained, through which the modem will communicate with the parent device that collects data, but also with the computer on which the application will run and with which the modem will be configured. Then, readers are introduced to the design of the user interface and architecture of the application, which includes the basic design principles which the application implementation was based on. The following is a description of the application implementation and the results of ModemTec modem configuration testing. Finally, the achieved results and possibilities for future modification are summarized.
