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.
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.
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.
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.

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.
Modem -repeater for narrow band technology of PLC
Novák, Michal ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
This semestral thesis focuses on the circuit design of the repeater for PLC communication in order to achieve greater distance in communication. It can also serve as a bridge for a separate modem device power grid. In this work we discuss the involvement of individual assembly parts repeater and proposed method of connection.
Energy meter with PLC communication
Szalbot, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Our thesis is about development of equipment, which combine two technology. First technology is wattmeter which is used to energy measurement and second is Power line communication. Wattmeter needs two variables for measurement, voltage and current. Voltage measurement is less difficult than measurement of current. Voltage can be reduce and measured by A/D converter. Current has to be transform to voltage and than can be measured same way. To do that we use current transformer. Than we design program for the microcontroller, involvement and PCB. Wattmeter is connect to PLC modem which has been chosen. Fusing this two technology we create wattmeter network. Next step was program which is used to network control and data collecting. This data are used to create charts in web application.
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.
