Embodiment Construction

[0025] The upper part of the figure shows a home network based on power line communication in which different application devices 20 - 25 are connected to the three phases 11 , 12 and 13 of the power line 10 . These application devices can be, for example, a TV 20 on the first phase line 11, a video recorder 21 and a hard disk (HD) video recorder 22, a PC 23 on the second phase line 12, a Washing machines 24 and other applications 25 . In this type of configuration, communication problems between two application devices (such as a video recorder 21 and a PC 23 ) connected to different phase lines 11 , 12 may occur.

[0026] To solve this problem, according to the invention, a transponder 1 is connected to the phase lines 11, 12 and 13, wherein the transponder 1 is preferably installed in the central position of the meter box 6 or in an auxiliary distribution cabinet. However, the only important consideration is that the transponder 1 can be installed in a location where there...

Abstract

The invention relates to a method and a device ( 1 ) for data transmission in a power supply network (power line communication). The device ( 1 ), preferably centrally located in a distribution box ( 6 ), is equipped with transceivers ( 3, 4, 5 ), each one of which is connected to a phasing line ( 11, 12, 13 ) of the power supply network, from which it can receive data, and to which it can transmit data. The transceivers are coupled via a control unit ( 2 ), wherein the control unit ensures that the data received from a phasing line can be transmitted, prepared, on at least one other phasing line. Hereby, a re-transmission on all phasing lines with the same transmission power, or a re-transmission matched to the particular signal strengths or the addressees of the data, can take place.

Description

technical field [0001] The invention relates to a method and a device for data transmission in a power network. Background technique [0002] "Power Line Communication" (PLC) refers to a known method by which data is transmitted over the wires of a power network intended to supply electricity. The advantage of this type of power line communication lies primarily in the fact that, in more or less every home, lines belonging to the power grid are present in practically every room. This makes it possible to interconnect applications in different rooms without rewiring. At the same time, in this respect, signal transmission over power lines has hitherto only been permitted in a small frequency range according to obsolete statutory regulations, and these limits will be exceeded in the future, making data rates of more than 10 Mbit / s possible. Here, power line communication can be used not only as a main means of accessing the so-called "last mile" to the Internet through a powe...
