Abstract

SYSTEME DE LOCALISATION D’AU MOINS UN DISPOSITIF EMETTEUR A PARTIR D’UNE SOURCE RADIO ENERGISANTE Système de localisation d’au moins un dispositif émetteur (EM1) comportant : un dispositif émetteur (EM1) comportant un module d’émission radio UWB et un module de réception radio UHF pour collecter des signaux afin d’alimenter électriquement le module d’émission, chaque émission d’un signal UWB étant générée à partir d’un niveau seuil d’énergie collectée ;une pluralité de balises (B1, B2, B3) de réception du signal UWB et horodatant chaque signal UWB reçu, lesdites balises comportant des interfaces pour émettre des trames de données vers un serveur distant,le serveur recevant les trames étant configuré pour :calculer une première donnée de localisation dudit dispositif émetteur ;calculer une fréquence d’émission d’un signal UWB à partir d’une pluralité de réception de messages UWB dudit dispositif émetteur, ladite fréquence d’émission étant comparée à une valeur de référence pour déduire une seconde donnée de localisation dudit dispositif émetteur. Figure pour l’abrégé : Fig. 1SYSTEM FOR LOCATING AT LEAST ONE TRANSMITTER DEVICE FROM AN ENERGIZING RADIO SOURCE System for locating at least one transmitter device (EM1) comprising: a transmitter device (EM1) comprising a UWB radio transmitter module and a UHF radio reception unit for collecting signals in order to electrically supply the transmission module, each transmission of a UWB signal being generated from a threshold level of collected energy;a plurality of beacons (B1, B2, B3 ) of reception of the UWB signal and timestamping each UWB signal received, said beacons comprising interfaces for transmitting data frames to a remote server, the server receiving the frames being configured to:calculate a first location datum of said transmitter device;calculate a frequency of transmission of a UWB signal from a plurality of receptions of UWB messages from said transmitter device, said transmission frequency being compared with a reference value to deduce a second location datum of said transmitter device.
