POSITION FINDING SYSTEM
First Claim
1. A position finding system comprising:
- a sensor unit having a first RFID transponder reader unit, a first inductive detector unit, and an analysis unit connectable to the RFID transponder reader unit and the inductive detector unit; and
a transmitter unit having an RFID transponder and a component transmitter unit that is made of a metallic material, the sensor unit being configured to be movable relative to the transmitter unit,wherein the RFID transponder reader unit is set up for absolute position determination and outputs a first position value,wherein the inductive detector unit is set up for absolute position determination and outputs a second position value, andwherein the analysis unit is configured to determine, from the data acquired from the transmitter unit, an absolute position of the sensor unit based on the first and second position values.

Abstract
Position finding system having a sensor unit and a transmitter unit. The sensor unit comprises a first RFID transponder reader unit, a first inductive detector unit, and an analysis unit connected to the RFID transponder reader unit and the inductive detector unit; the transmitter unit comprises an RFID transponder and a metallic material. The sensor unit is movable relative to the transmitter unit. The RFID transponder reader unit is configured for absolute position finding and outputs a first position value, and the inductive detector unit is configured for absolute position finding and outputs a second position value. The analysis unit is configured to determine, from the data acquired from the transmitter unit, an absolute position of the sensor unit from the first and second position values.

13. A method for determining an absolute position, the method comprising:
-
providing a sensor unit having at least one RFID transponder reader unit, an inductive detector unit, and an analysis unit connectable to the RFID transponder reader unit and the inductive detector unit; providing a transmitter unit having an RFID transponder, a component transmitter unit made of a metallic material, and a plurality of transmitter units arranged in a row; outputting a first position value by the RFID transponder reader unit for absolute position finding; outputting a second position value by the inductive detector unit for absolute position finding; and determining an absolute position of the sensor unit via the analysis unit from position values acquired from the transmitter unit based on the first and second position values. - View Dependent Claims (14, 15)
