Construcción de un sistema de adaptación de impedancias para la transmisión de audio, video y datos a través de Líneas de Potencia (PLT).

Abstract

Impedance System was made for the transmission of audio, video and data over power lines, focused primarily on the distribution networks within a home was built. For impedance matching method lumped elements consisting of capacitors ando inductors used. To proceed with this implementation an analysis of the characteristics, properties and structure of the grid, impedance matching with lumped elements and a review of the Power Line Telecommunication (PLT) technology was performed. After making an analysis of the loads to be supported in the transmission line impedance range broadcasting system it was obtained. Then he proceeded to obtain the values og inductance and capacitance using the Smith chart to be coupled to the transmission line. Then using the Arduino platform controller impedances which was built between the impedance adapter and driver impedance driver circuit impedance transmitter and receiver is integrated. Subsequently, we proceeded to perform adapter implementation system impedances with the range of impedances 370 Ω to 821Ω previously obtained consisting of three blocks: an input block that integrated a computer, a DVD, the converter, the transmitter itself said transmitter circuit and the impedance, the output block consists of the driver circuit impedances and monitor for receiving ando displaying data and finally the third block is the transmission médium forming the PLT. This adapter system reference impedance may be to implement as many PLT with connected laods.
