A utility network communication device is provided to detect whether anomalous events occur with respect to at least one node in a utility network. The communication device has recorded therein threshold operating information and situational operating information. The threshold operating information includes data indicative of configured acceptable operating parameters of the nodes in the utility network based on respective locational information of the nodes. The situational information includes data indicative of configured operation data expected to be received from nodes in the utility network during a predetermined time period, based on a condition and/or event occurring during the predetermined time period. The communication device receives operation data from nodes in the network, and determines whether the received operation data from a node in the network constitutes an anomalous event based on a comparison of the received operation data with (i) the threshold operating information defined for the node and (ii) the situational information. The communication device outputs notification of any determined anomalous event. L'invention concerne un dispositif de communication de réseau utilitaire permettant de détecter si des événements anormaux concernant au moins un noeud se produisent dans un réseau utilitaire. Des informations fonctionnelles de seuil et des informations fonctionnelles situationnelles sont enregistrées dans le dispositif. Les informations fonctionnelles de seuil contiennent des données indiquant les paramètres fonctionnels acceptables configurés des noeuds du réseau utilitaire sur la base des informations de localisation des différents noeuds. Les informations situationnelles contiennent des données indiquant les données fonctionnelles configurées attendues des noeuds du réseau utilitaire pendant une période prédéterminée, sur la base d'une condition et/ou d'un événement se produisant pendant ladite durée prédéterminée. Le dispositif de communication reçoit des noeuds du réseau les données fonctionnelles, et détermine si les données fonctionnelles reçues d'un noeud du réseau constituent un événement anormal sur la base d'une comparaison entre (i) les informations de seuil définies pour le noeud et (ii) les informations situationnelles. Le dispositif de communication émet une notification de tout événement anormal constaté.
