APPARATUS FOR POWER TRANSMISSION AND FOR INDUCTIVE COMMUNICATION

摘要

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.

1. Apparatus for power transmission to and inductive communication with a track-bound or rail-bound moving object: with a power 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line that can be contacted by a current collector to supply moving loads, from which line electric power can be withdrawn by the object during its movement; with a separate data line running parallel to the power transmission line; with at least one communication inductance that is arranged on the object and that can be magnetically coupled to the data line; and with a communication device connected to the communication inductance wherein, the communication device has a modem that operates according to an orthogonal frequency multiplex method at a data rate of at least 50 Mbit/sec.
