Title (EN) SELF ADJUSTING ANTENNA IMPEDANCE FOR CREDENTIAL DETECTION IN AN ACCESS CONTROL SYSTEM
(FR) IMPÉDANCE D'ANTENNE À RÉGLAGE AUTOMATIQUE POUR LA DÉTECTION DE JUSTIFICATIFS DANS UN SYSTÈME DE CONTRÔLE D'ACCÈS
Abstract:
(EN) An access control device including a credential reader circuit structured to enter a standby mode, awaken from a standby mode, and receive data from a nearby credential and a credential detection circuit. The credential detection circuit includes memory configured to store program instructions, an antenna circuit, and a processor electrically coupled to the antenna and to the credential reader circuit. The processor is configured to execute the stored program instructions to transmit an interrogation signal, receive a reflected interrogation signal with the antenna, transmit an activation signal to the credential reader circuit in response to the received reflected interrogation signal including I and Q values, receive a false detection signal from the credential reader circuit, and adjust an impedance of the antenna circuit.
(FR) Cette invention porte sur un dispositif de contrôle d'accès comprenant un circuit lecteur de justificatifs configuré pour entrer en mode veille, être réveillé d'un mode veille, et recevoir des données à partir d'un justificatif proche ainsi qu'un circuit de détection de justificatifs. Le circuit de détection de justificatifs d'identité comprend une mémoire configurée pour stocker des instructions de programme, un circuit d'antenne et un processeur couplé électriquement à l'antenne et au circuit lecteur de justificatifs d'identité. Le processeur est configuré pour exécuter les instructions de programme stockées pour transmettre un signal d'interrogation, recevoir un signal d'interrogation réfléchi avec l'antenne, transmettre un signal d'activation au circuit lecteur de justificatifs d'identité en réponse au signal d'interrogation réfléchi reçu comprenant des valeurs I et Q, recevoir un signal de fausse détection provenant du circuit lecteur de justificatifs d'identité, et ajuster une impédance du circuit d'antenne.
