Abstract
The present invention relates to a method of recognizing whether a transponder of an RFID system, comprising a reading device and the transponder, is present in a boundary region, wherein a comparison is made with at least one threshold value. In accordance with the invention a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined bit error rate for signals transmitted between the transponder and the reading device. The invention further relates to an RFID system and to a safety switch
Claims17
A method of recognizing whether a transponder of an RFID system, comprising a reading device and the transponder, is present in a boundary region, wherein a comparison is made with at least one threshold value, wherein a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined maximum bit error rate between the signals transmitted between the transponder and the reading device.
An RFID system comprising a reading device and a transponder, wherein the RFID system is configured for the purpose of carrying out a method in of recognizing whether the transponder of the RFID system is present in a boundary region, wherein a comparison is made with at least one threshold value, wherein a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined maximum bit error rate between the signals transmitted between the transponder and the reading device.
A safety switch having an RFID system comprising a reading device and a transponder, wherein the RFID system is configured for the purpose of carrying out a method in of recognizing whether the transponder of the RFID system is present in a boundary region, wherein a comparison is made with at least one threshold value, wherein a bit error rate of signals transmitted between the transponder and the reading device is determined and the at least one threshold value comprises a predefined maximum bit error rate between the signals transmitted between the transponder and the reading device.
