Description

Anschluß eines Modems als Einspeisemöglichkeit für Daten bei der leitungsgebundenen Datenübertragung an einer VerteilervorrichtungConnection of a modem as a feed-in option for data during wired data transmission to a distribution device

Die Erfindung betrifft die Verwendung einer Vorrichtung zum elektrischen Anschließen eines Modems als Einspeisemöglichkeit für Daten bei der leitungsgebundenen Datenübertragung in einer Verteilervorrichtung an Stromleitungen.The invention relates to the use of a device for the electrical connection of a modem as a feed option for data in line-bound data transmission in a distribution device on power lines.

Bei der leitungsgebundenen Datenübertragung werden Datensignale neben der üblichen 50 Hz-Spannung auf Stromleitungen aufmoduliert. Hierbei übersteigen die Pegel der Signalspannungen den Einvolt-Wert nicht und die Frequenzen liegen, abhängig von dem benutzten Modulationsverfahren, im Bereich von etwa 1,5 bis 30 MHz. Die Verbindung zwischen Geräten, die in einem vermaschten Stromnetz angeschlossen sind, erfolgt nach den Prinzipien eines Datennetzes mit einem Bus als Medium. Da die hochfrequenten Signale mit steigender Entfernung gedämpft werden, ist der Einsatz von Zwischenverstärkern nötig. Diese müssen an Verteilervorrichtungen, wie beispielsweise Trafostationen, Straßenverteilern oder Hausanschlußkästen angebracht werden.In the case of wired data transmission, data signals are modulated on power lines in addition to the usual 50 Hz voltage. In this case, the levels of the signal voltages do not exceed the one-volt value and, depending on the modulation method used, the frequencies are in the range from approximately 1.5 to 30 MHz. The connection between devices that are connected in a meshed power network is based on the principles of a data network with a bus as the medium. Since the high-frequency signals are attenuated with increasing distance, the use of repeaters is necessary. These must be attached to distribution devices, such as transformer stations, street distributors or house connection boxes.

Der Anschluß dieses Modems erfolgt üblicherweise über herkömmliche Netzstecker, wie sie in jedem Haushaltsgerät vorhanden sind. Da aber an den Verteilervorrichtungen meistens keine Steckdose vorhanden ist, muss der Anschluß direkt an der Sammelschiene des Stromnetzes erfolgen. Dies hat aber zur Folge, dass die betreffende Teilmasche für die Durchführung dieser Arbeiten abgeschaltet werden muss.This modem is usually connected using conventional power plugs, such as those found in every household appliance. However, since there is usually no socket on the distribution devices, the connection must be made directly to the busbar of the power network. However, this means that the relevant sub-mesh must be switched off to carry out this work.

Die Verbindung ist als Schraubverbindung ausgestaltet, die z.B. an einer Sammelschiene des Energieübertragungsnetzes befestigt wird. Die Verbindung zur Datenübertragungseinrichtung erfolgt über eine im Mantel des Gehäuses angeordnete Steckdose.EP 1 079 538 AI discloses a coupling unit with an integrated plug contact area for coupling a data transmission device. direction to (ΪTe "-? hase of an electrical transmission network known, in which the coupling unit is housed in an externally electrically insulated housing and is connected via a connection point to a conductor of a 3-phase power network.
