Abstract

L'invention concerne un procédé de détection de fuite dans un circuit de distribution d’une ressource, ressource dont une consommation est matérialisée sous la forme d’un train d’horodates H(x), x étant un nombre entier, chaque horodate étant associée à la consommation d’une unité de la ressource, procédé au cours duquel : * ET1 : dans le train d’horodates, on détermine au moins une période creuse PC(y) correspondant à une consommation inférieure à une consommation minimale prédéfinie Cm au cours d’une période de durée prédéfinie T, * ET2 : on détermine un risque de fuite en fonction d’une différence entre un temps moyen écoulé entre la consommation de deux unités de ressources successives consommées pendant la période creuse PC(y) et un temps écoulé entre la consommation de deux unités de ressources successives pendant la période creuse PC(y). Application à la détection de microfuite dans un circuit de distribution d’une ressource, par exemple de l’eau, de l’électricité ou du gaz. Figure pour l'abrégé : Figure 1The invention relates to a method for detecting a leak in a distribution circuit of a resource, a resource of which consumption is materialized in the form of a train of timestamps H (x), x being an integer, each timestamp being associated with the consumption of one unit of the resource, process during which: * ET1: in the train of timestamps, at least one off-peak period PC (y) corresponding to a consumption lower than a predefined minimum consumption Cm au during a period of predefined duration T, * ET2: a risk of leakage is determined as a function of a difference between an average time elapsed between the consumption of two successive resource units consumed during the off-peak period PC (y) and a time elapsed between the consumption of two successive resource units during the off-peak period PC (y). Application to the detection of microleaks in a distribution circuit of a resource, for example water, electricity or gas. Figure for abstract: Figure 1
