The connecting line (4) of the modem (1) comprises a mains plug (5). The invention is characterised in that Said mains plug (5) is provided with a wide band network filter (3) for filtering disruptive impulses by inductive or capacitive consumers and is provided with high frequency currents reinjected into the network.

Description

Vorrichtung zum elektrischen Anschließen eines Modems bei der leitungs gebundenen Datenübertragung an ein Stromnetz Device for the electrical connection of a modem in line-bound data transmission to a power grid
Die Erfindung betrifft eine Vorrichtung zum elektrischen Anschließen eines Modems bei der leitungsgebundenen Datenübertragung an ein Stromnetz, wobei die Verbindungsleitung des Modems einen Netzstecker aufweist.The invention relates to a device for the electrical connection of a modem in the case of line-bound data transmission to a power grid, the connection line of the modem having a power plug.
Bei der leitungsgebundenen Datenübertragung werden Datensignale neben der üblichen 50 Hz-Spannung auf Stromleitungen aufmoduliert. Hierbei übersteigen die Pegel der Signalspannungen den 1 V-Wert nicht und die Frequenzen liegen, abhängig von den benutzten Modulationsverfahren, im Bereich von 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.In the case of wired data transmission, data signals are modulated on power lines in addition to the usual 50 Hz voltage. The levels of the signal voltages do not exceed the 1 V value and the frequencies are in the range from 1.5 to 30 MHz, depending on the modulation method used. 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.
Die DE 40 31 092 AI beschreibt ein Fernsprechsystem, bei dem mit Hilfe von zwei Modems der Anschluß eines Fernsprechapparates an das öffentliche Telekom-Netz durch eine Übertragung der Signale über das elektrische Stromnetz an einen beliebigen Punkt innerhalb eines Gebäudes gelegt werden kann. Der Telefonanschluß wird hierfür mit dem ersten Modem verbunden, welches in eine erste Steckdose des Stromnetzes eingesteckt wird, und der Fernsprechapparat wird mit seinem zugehörigen Anschlußstecker in eine Telefonbuchse eingesteckt, die im zweiten Modem vorgesehen ist, welches unmittelbar in eine beliebige weitere Steckdose des Stromnetzes eingesteckt wird.DE 40 31 092 AI describes a telephone system in which with the help of two modems the connection of a telephone set to the public telecommunications network can be placed at any point within a building by transmitting the signals via the electrical power network. For this purpose, the telephone connection is connected to the first modem, which is plugged into a first socket of the mains, and the telephone set is plugged into a telephone socket with its associated connector, which is provided in the second modem, which is plugged directly into any other socket of the mains becomes.
Die DE 44 18 296 AI beschreibt eine Netzkoppeleinrichtung für Systeme zur Datenübertragung über ein elektrisches Verteilernetz, bei der zur Filterung und Verstärkung eines aus dem Netzsignal ausgekoppelten HF-Empfangssignals eine Kette von Filter- und Verstärkerstufen als Regelstrecke wenigstens eines Regelkreises zum Einsatz gelangen, mit denen die Verstärkung in der Weise geregelt werden kann, dass Verzerrungen des Empfangssignals weitgehend vermieden werden.DE 44 18 296 AI describes a network coupling device for systems for data transmission via an electrical distribution network, in which a chain of filter and amplifier stages is used to filter and amplify an RF reception signal decoupled from the network signal can be used as a controlled system of at least one control circuit with which the amplification can be controlled in such a way that distortions of the received signal are largely avoided.
Schließlich beschreibt die DE 44 25 876 AI eine intelligente stationäre oder mobile Steckdose zum Anschluß elektrischer Verbraucher, wobei die Verbraucher über ein leistungsfähiges BUS-System gesteuert werden, welches das Starkstromnetz als Übertragungsmedium verwendet.Finally, DE 44 25 876 AI describes an intelligent stationary or mobile socket for connecting electrical consumers, the consumers being controlled via a powerful BUS system which uses the power grid as the transmission medium.
Der Anschluß des Modems erfolgt normalerweise über übliche Netzstecker, wie sie an Haushaltsgeräten vorhanden sind. Die langen, ungeschirmten und geradlinig verlaufenden Stromleitungen wirken für hochfrequente Signale wie Antennen. Im Spektrum des Signals sind alle Radiosender hörbar. Diese Störungen aus der Sicht der leitungsgebundenen Datenübertragung, können nicht umgangen werden. Eine andere Störquelle sind Haushaltsgeräte (induktive oder kapazitive Verbraucher), zum Beispiel alle Geräte mit Motoren, die hochfrequente Impulse ins Netz zurückspeisen.The modem is usually connected using the usual power plugs found on household appliances. The long, unshielded and rectilinear power lines work for high-frequency signals like antennas. All radio stations are audible in the spectrum of the signal. These disturbances from the perspective of wired data transmission cannot be avoided. Another source of interference is household appliances (inductive or capacitive consumers), for example all appliances with motors that feed high-frequency pulses back into the network.
Der Erfindung liegt die Aufgabe zugrunde, diese Störimpulse durch eine einfache Einrichtung zu beseitigen.The invention has for its object to eliminate these glitches by a simple device.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Netzstecker mit einem Breitband-Netzfilter zum Ausfiltern von Störimpulsen durch induktive oder kapazitive Verbraucher und von in das Netz zurückgespeisten hochfrequenten Strömen versehen ist.This object is achieved according to the invention in that the power plug with a broadband network filter for filtering out Interference pulses are provided by inductive or capacitive consumers and by high-frequency currents fed back into the network.
Die Erfindung bringt den Vorteil, dass der Nutzer der Einrichtung keine zusätzlichen Geräte oder Installationen braucht, um diese Störimpulse auszuschließen. Er braucht lediglich den Netzstecker an das Stromnetz anzuschließen bzw. in die entsprechende Steckdose einzustecken.The invention has the advantage that the user of the device does not need any additional devices or installations to exclude these interference pulses. All he has to do is connect the mains plug to the mains or plug it into the appropriate socket.
Die Erfindung wird in der nachfolgenden Beschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail in the following description with reference to an embodiment shown in the drawing.
In der Zeichnung ist eine herkömmliche Steckdose 2 dargestellt, in die ein Netzstecker 5, der über eine Verbindungsleitung 4 mit dem Modem 1 verbunden ist, eingesteckt wird.
