Apparatus for power transmission and for inductive communication
First Claim
1. Apparatus for power transmission to and data communication with a track-bound or rail-bound moving object which receives power from a transmission line running along an intended movement path of the object, in particular in the form of a collector line that can be contacted by a current collector to supply moving loads, from which line electric power can be withdrawn by the object during movement, the apparatus comprising:
- a separate data line running parallel to the power transmission line;
at least one communication inductance that is arranged on the object and that can be magnetically coupled to the data line;
a communication device connected to the communication inductance including a modem that operates according to an orthogonal frequency multiplex method at a data rate of at least 50 Mbit/sec; and
a metallic shield surrounding the data line and forming an interior space, the metallic shield separating the data line from the power transmission line, the metallic shield having a slot extending along its longitudinal direction through which the communication inductance can be introduced into the interior space to a position adjacent to the data line to thereby magnetically couple the communication inductance to the data line while the object is moving.

Abstract
Apparatus for power transmission and for inductive communication with a track or rail-guided moving object, with a power transmission line which extends along an envisaged path of movement of the object—with which a current collector can make contact—for supplying power to moving loads, a separate data line, at least one communication inductance on the object coupleable magnetically to the data line, and with a communication device which is connected to the communication inductance. The communication device has a modem which operates on the basis of an orthogonal frequency-division multiplexing method at a data rate of at least 50 MBit/s. One end of the data line is connected to a communication device connected to a central control unit and containing a modem of the same type as the communication device in the moving object.

17. A method for power transmission to and data communication with a track-bound or rail-bound moving object, the method comprising:
-
providing a communication device including a modem that is configured for communication between stationary subscribers via power supply lines of a building and which operates according to an orthogonal frequency multiplexing method with a data rate of at least 50 Mbit/sec; providing a data line extending along a movement path of the object, the data line connected to the communication device and disposed parallel to and separate from a power transmission line, the power transmission line including a collector line that can be contacted by a current collector of the object for electrically supplying moving loads; introducing a communication inductance connected to the object into a metallic shield surrounding the data line and forming an interior space, the metallic shield separating the data line from the power transmission line, the metallic shield having a slot extending along its longitudinal direction through which the communication inductance can be introduced into the interior space to a position adjacent to the data line to thereby magnetically couple the communication inductance to the data line while the object is moving.
