A utility meter endpoint measures consumption of a commodity such as water, gas, or electricity, includes a configurable function for detecting the presence of an abnormality in consumption such as leaks, tampering, short- circuits or other malfunctions, or unauthorized bypassing of the meter, and the like. The endpoint can take multiple samples according to a configurable time schedule, and test the usage pattern against programmable criteria that reflect certain types of unusual activity or other problems. If the criteria are satisfied, the endpoint can report the occurrence of the unusual event to the AMR system during its usual communications cycle or by initiating a special, unscheduled communication to signal an alarm condition.

L'invention concerne une extrémité d'un dispositif de mesure utilitaire mesurant la consommation d'une marchandise, telle que l'eau, le gaz, ou l'électricité, comprenant une fonction pouvant être configurée permettant de détecter la présence d'un anomalie dans la consommation, telle qu'une fuite, une altération, des courts-circuits ou toute autre défaillance, ou une dérivation non autorisée du dispositif de mesure et analogues. L'extrémité peut collecter de nombreux échantillons selon un horodatage configurable, et tester un modèle d'usage contre des critères programmables qui reflètent certains types d'activités inhabituelles ou tout autre problème. Si les critères sont satisfaits, l'extrémité peut rapporter la présence d'un événement inhabituel au système AMR lors du cycle de communications ou lors du démarrage d'une communication spéciale, non inscrite, permettant de signaler une condition d'alarme.
