Abstract

In local data networks, it has hitherto been necessary to lay a separate cable for data transmission in addition to the power supply. In the case of premises which have not been prepared for the laying of additional cables, the outlay of this may exceed the costs of the network itself. The object of the invention is to solve this problem. The object is achieved by using the AC voltage system for data transmission also.

Aufgabe Der Erfindung liegt die Aufgabe zugrunde, ein lokales Datennetzwerk zu entwickelns das ohne die getrennte Verlegung eines übertragungsmediums auskommt.1.4.3. Sources W. Girardet Fachzeitschriftenverlag GmbH ELECTRONIC APPLICATIONS (ISSN 0720-101X) 15.Jg. 1983 No. 4 p.26 LOCAL NETWORKS 1.5. Object of the invention The underlying task is to develop a local data network without the separate laying of a transmission medium is sufficient.

1.6. Lösung Die Aufgabe wird erfindungsgemäß dadurch gelöste daß die Datenübertrsgung uber die Leitungen des allgemeinen Wechselspannungsnetzes (110V-380V, 50Hz-60Hz) erfolgt und daß alle Sende-und Empfangsstationen gleichermehen in der Art eines Bus-Systems an der Datenübertragung teilnehmen können.1.6. Solution The object is achieved according to the invention in that the Data transmission via the lines of the general AC voltage network (110V-380V, 50Hz-60Hz) and that all transmitting and receiving stations work in the same way Kind of a bus system can participate in the data transmission.

Ferner kann der Belegungszustand des Netzes durch eine Pegelmessung im übertragungsfrequenzbereich ermittelt werden. Die Datenübertragung kann dann mit dem CDMA-Verfahren abgewickelt werden. Die einzelnen Stationen brauchen sich nur durch die Zuteilung unterschiedlicher Geräteadressen zu unterscheiden.Furthermore, the occupancy status of the network can be determined by measuring the level can be determined in the transmission frequency range. The data transfer can then can be processed using the CDMA procedure. The individual stations need each other can only be distinguished by the allocation of different device addresses.

Die Datenübertragung erfolgt mit Hilfe selektiver Verstärker und Filter im Frequenzbereich von SOHz-1OOkHz. Die obere Grenzfrequenz dient zur Einhaltung der entsprechenden Funkschutzvorschriften.The data transfer takes place with the help of selective amplifiers and Filters in the frequency range from SOHz-1OOkHz. The upper limit frequency is used for compliance the corresponding radio protection regulations.

Als Modulationsverfahren zur Datenübertragung werden die bei Floppy-Disk-Systemen verwendeten Modulatiosverfahren FM und MFM verwendet.The modulation method used for data transmission in floppy disk systems used modulation methods FM and MFM.

1.7. Erzielbare Vorteile Der Vorteil der Erfindung liegt darin, daß durch die Benutzung des sowieso vorhandenen Wechselspannungsnetzes auf die getrennte Verlegung eines übertragungsmediums verzichtet werden kann.1.7. Achievable Advantages The advantage of the invention is that through the use of the existing AC voltage network on the separate Laying a transmission medium can be dispensed with.

In vielen Fallen wird durch die Verlegung eines solchen Kabels eine Renovierung der betroffenen Raume notwendig. Die dafür aufzuwendenden Kosten können dabei leicht die Kosten des Netzwerks überschreiten.In many cases the installation of such a cable will result in a Renovation of the affected rooms necessary. The costs incurred for this can easily exceed the cost of the network.

Durch die Erfindung entstehen weder Kosten fUr die Verlegung des übertragungsmediums noch für das Kabel selbst.The invention does not incur any costs for relocating the transmission medium nor for the cable itself.

1.8. Beschreibung eines Rusführungsbeispiels (Fig. 1) Die in Fig.1 dargestellte Schaltung zeigt den Aufbau einer Station am Netzwerk und deren Anschluß an das Wechselspannungsnetz.1.8. Description of an exemplary embodiment (Fig. 1) The in Fig.1 The circuit shown shows the structure of a station on the network and its connection to the AC voltage network.

Die Netzspannung wird dabei einerseits über ein Netzfilter CNF13 zum Netzteil [NT] geführt und dient so zur Stromversorgung des gesamten Gerätes. Zur Datenübertragung wird die Netzspannung durch einen übertrager [ü] galvanisch getrennt. Der übertrager ist an die Sende- und Empfangsverstarker angeschlossen. Mit Hilfe eines Modems EM werden die Daten von oder zum Computer CC übertragen.The mains voltage is on the one hand via a mains filter CNF13 to the Power supply unit [NT] and is used to power the entire device. To the Data transmission, the mains voltage is galvanically separated by a transformer [ü]. The transmitter is connected to the transmit and receive amplifiers. With help a modem EM, the data are transmitted from or to the computer CC.

Das zweite Netzfilter CNF23 dient dazu, eine Einschleusung der Daten in das EVU-Netz zu verhindern und andererseits die Datenübertragung vor Störungen aus dem Netz zu schützen.The second line filter CNF23 is used to inject the data in the utility network and, on the other hand, to prevent data transmission from malfunctions to protect from the network.

Mehrere so aufgebaute Stationen können Daten untereinander über die Netzleitung übertragen.Several stations structured in this way can share data with each other via the Transfer power line.
