Abstract

Die Ausführungsformen der vorliegenden Offenbarung betreffen Übertragung über Stromverteilungsleitungen (PLC), insbesondere eine PLC-Verarbeitungsschaltung (1) und deren Betriebsverfahren. Die PLC-Verarbeitungsschaltung (1) umfasst: eine Trägersignalverarbeitungseinheit (101), die dazu eingerichtet ist, in einem Empfangszustand ein Leistungsträger-Eingangssignal zu empfangen und das in ein Eingangsnetzwerksignal umzuwandeln, sowie in einem Sendezustand ein Ausgangsnetzwerksignal zu empfangen und das in ein Leistungsträger-Ausgangssignal umzuwandeln; eine Netzwerkübertragungsverarbeitungseinheit (102), die dazu eingerichtet ist, in dem Empfangszustand das Eingangsnetzwerksignal zu empfangen und das in ein Ausgangsdigitalsignal umzuwandeln, sowie in dem Sendezustand ein Eingangsdigitalsignal zu empfangen und das in das Ausgangsnetzwerksignal umzuwandeln; und eine Signalumwandlungseinheit (103), die dazu eingerichtet ist, in dem Empfangszustand das Ausgangsdigitalsignal zu empfangen und das in ein Ausgangssignal umzuwandeln, sowie in dem Sendezustand ein Eingangssignal zu empfangen und das in das Eingangsdigitalsignal umzuwandeln. Die hier beschriebene PLC-Verarbeitungsschaltung (1) ermöglicht die kostengünstige Installation vom Video-Intercom-System. Ferner wird die Kommunikationsbandbreite erhöht und die Wahrscheinlichkeit von Geräteschäden verringert.The embodiments of the present disclosure relate to transmission over power distribution lines (PLC), in particular to a PLC processing circuit (1) and its method of operation. The PLC processing circuit (1) comprises: a carrier signal processing unit (101) which is set up to receive a power carrier input signal in a reception state and to convert it into an input network signal, and to receive an output network signal in a transmission state and to convert it into a power carrier convert output signal; a network transmission processing unit (102) arranged to receive the input network signal and convert it into an output digital signal in the receiving state and to receive an input digital signal and convert it into the output network signal in the transmitting state; and a signal converting unit (103) arranged to receive the output digital signal and convert it into an output signal in the receiving state and to receive an input signal and convert it into the input digital signal in the transmitting state. The PLC processing circuit (1) described here enables the cost-effective installation of the video intercom system. It also increases communication bandwidth and reduces the likelihood of device damage.
