Abstract

Un procédé de localisation d’au moins un produit (L1, L2) dans un bâtiment industriel (B) comprenant une pluralité de zones unitaires (Z1-Z6) comprenant : une étape d’émission (E1) d’un signal d’interrogation selon un premier rayonnement d’interrogation (I1), une étape de réception (E2), par un lecteur RFID (3), d’un signal de réponse (REP) par chaque balise de zone (11-16), le signal de réponse (REP) comprenant l’identifiant de zone (ID11-ID16), une étape de réception (E3), par le lecteur RFID (3), d’un signal de réponse (REP) par chaque balise de produit (ID21, ID22), le signal de réponse (REP) comprenant l’identifiant de produit (ID21, ID22), une étape d’association E4 de l’identifiant/des identifiants de produit (ID21, ID22) à l’identifiant/aux identifiants de zone (ID11-ID16) dans une base de données pour le premier rayonnement d’interrogation (I1), l’association étant exempte de mesure de puissance d’un signal de réponse, une étape de renouvellement des étapes E1 à E4 pour au moins un deuxième rayonnement d’interrogation et une étape de détermination E5 de la zone unitaire (Z1-Z6) dans laquelle chaque produit (L1, L2) est situé par analyse statistique de la base de données. Figure de l’abrégé : Figure 7A method for locating at least one product (L1, L2) in an industrial building (B) comprising a plurality of unitary zones (Z1-Z6) comprising: a step of transmitting (E1) an interrogation signal according to a first interrogation radiation (I1), a step of reception (E2), by an RFID reader (3), of a response signal (REP) by each zone beacon (11-16), the response (REP) comprising the zone identifier (ID11-ID16), a step of reception (E3), by the RFID reader (3), of a response signal (REP) by each product tag (ID21, ID22 ), the response signal (REP) comprising the product identifier (ID21, ID22), a step E4 of associating the product identifier(s) (ID21, ID22) with the zone identifier(s) (ID11-ID16) in a database for the first interrogation radiation (I1), the association being free of power measurement of a response signal, a step of renewing steps E1 to E4 for at least ns a second interrogation radiation and a step E5 for determining the unit area (Z1-Z6) in which each product (L1, L2) is located by statistical analysis of the database.
