Saidi, M.Z.Bentarzi, HamidRefoufi, L.2015-06-172015-06-172010978-960474187-8https://dspace.univ-boumerdes.dz123456789/2016In the present paper is described the scheme of a Power Line Communication (PLC) control system for energy management. The control system described is based on the Spread Spectrum Carrier Technology (SSCT) for the transmission of control information over the power line. This technique employs a series of short frequency swept chirps that act as carrier. The swept frequency chirps are generated by the implementation of a look up table stored in a ROM section. The choice of using a ROM is based on a hardware solution that allows the chirps generation under accurate timing. Another reason is the possibility to generate the chirps in their different modulated forms. Information data is converted to chirps according to the Consumer Electronics Bus (CEBus) standard that sets the transmission protocols and the modulation technique. Energy management to be achieved requires the control of various devices existing in buildings and houses and leading to the concept of Home AutomationenEnergy managementPower Line CommunicationSpread Spectrum Carrier Technology (SSCT)Accurate timingControl informationElectrical energy managementFrequency sweptHardware solutionsHome automationIn-buildingsInformation dataLook up tableModulation techniquesSwept-frequencyTransmission protocolsArticle
