Device for inductively supplying power and guiding a mobile object

Device for inductive power supply and guidance of a moving object, comprising:

• a primary inductance element extending as a conductive loop along a path provided for the object,
• a secondary inductance element arranged on the object and coupled magnetically with the primary inductance element for power transmission,
• a plurality of receiver inductance elements arranged on the object and which output measurement signals dependent on the magnetic field of the primary inductance element, and
• an evaluation device, which determines a measure for the position of the object with reference to the conductive loop from the measurement signals, wherein a regular arrangement of receiver inductance elements is provided, which extends on the object at least perpendicular to the object's direction of motion, in that the receiver inductance elements are simultaneously also connected to a data receiver device, which contains means for extracting a data signal from the output voltage of at least one of the receiver inductance elements, and in that at least one data line, which exhibits inductive coupling with at least one of the receiver inductance elements sufficient for transmitting a data signal while the object is moving, is arranged along the path provided for the object,
• wherein the frequency band used for the data transmission differs significantly from the operating frequency of the power supply and in that there is at least one filter device for separating the position measurement signals and the data signals.
