Abstract

Die Erfindung betrifft ein Kommunikationssystem, bestehend aus einer zentralen Kommunikationseinheit ZKE und mindestens einer kabellosen peripheren Kommunikationseinheit PKE, die über eine elektromagnetische Kopplung miteinander in Verbindung stehen und einen Datenverkehr über eine Welle vorgegebener Frequenz aufweisen sowie eine unidirektionale Energieübertragung zur Stromversorgung der peripheren Kommunikationseinheit aufweisen. Der Erfindung liegt die Aufgabe zugrunde, ein Kommunikationssystem mit einer zentralen und mindestens einer peripheren Kommunikationseinheit zu schaffen, die jederzeit systemverfügbar, kommunikationsbereit und leicht bedienbar ist. Die Lösung besteht darin, daß die magnetische Kopplung mittels eines die Spulen (10, 12) enthaltenden Bandfilters (15, 27) durchgeführt wird und der Datenverkehr von der PKE (11) zur ZKE (1, 4) über die Welle der vorgegebenen Frequenz durch Verstimmung oder Belastungsänderung des PKE-seitigen LC-Schwingkreises (27) erfolgt und die dadurch am ZKE-seitigen LC-Schwingkreis (15) entstehenden Amplitudenänderungen von der dort angeschlossenen Demodulationseinrichtung (20) zusammen mit dem von der ZKE (1, 4) gesendeten modulierten Datensignal demoduliert werden, und daß in der ZKE (1, 4) eine Verknüpfungsschaltung (19) vorgesehen ist, in der das Modulations-Datensignal der ZKE (1, 4) von dem von der Demodulationseinrichtung (20) gelieferten Signal subtrahiert wird, so daß ausgangsseitig ein Differenzdatensignal als Datensignal der PKE (11) zur Verarbeitung in die ZKE (1, 4) weiterleitbar ist.
