Detection system for an absolute angular position on the basis of radio frequency identification technology -

摘要

A system for providing a hf - query, wherein the system comprises:two cam shafts wheels (90, 92), in each case at one end of a separate camshaft are mounted;a plurality of rfid - labels (94, 96), which is located around an outer circumference of each camshaft wheel (90, 92) are arranged around; andan rfid - transceiver (98), of the adjacent to the two cam shafts wheels (90, 92) is arranged and the rfid - labels (94, 96) on the two cam shafts wheels (90, 92), the rfid - transceiver an interrogation signal to the two cam shafts wheels (90, 92), the the rfid - labels (94, 96) is activated and has the effect that the rfid - labels (94, 96) of the two cam shafts wheels (90, 92) a coded signal is transmitted, the of the transceiver (98) is received and the position of the respective camshaft wheel (90, 92), when it rotates.
