Abstract

Selon un mode de réalisation de l'invention, l'appareil permettant de contrôler des infractions au code de la route au moyen d'une RFID et de contrôler un feu de circulation en fonction des conditions de circulation comprend : des antennes RFID qui reçoivent des signaux d'une étiquette RFID en provenance d'un objet mobile et qui sont installées à des intervalles prédéterminés de façon à mesurer la différence de valeur de phase des signaux d'étiquette RFID reçus ; un lecteur RFID permettant de communiquer sans fil avec l'étiquette RFID et d'analyser les informations incluses dans les signaux reçus de l'étiquette RFID ; une unité de commande permettant de calculer les informations analysées et de déterminer ainsi l'infraction au code de la route de l'objet mobile sur lequel est montée l'étiquette RFID, ainsi que les conditions de circulation ; une unité de commande de feu de circulation permettant de commander un feu de circulation en fonction des conditions de circulation déterminées par l'unité de commande ; et une unité de communication permettant de transmettre à un serveur le fait que l'objet mobile a commis une infraction au code de la route, les informations incluses dans les signaux reçus de l'étiquette RFID pouvant comprendre des informations sur un numéro de véhicule, l'intensité des signaux de l'étiquette RFID, ainsi que la valeur de phase (phi) des signaux de l'étiquette RFID.
