Abstract
Electric meters are connected by an electricity supply network to a data concentrator with which the meters communicate by powerline. A method for reading information from meters is based on a classification of the meters in a plurality of classes. A first class, read first, groups together meters that haven't been read in a last execution of the method. The other classes group together the meters according to a rate of response to requests for information coming from the concentrator. The classes grouping together the meters that have the lowest response rates are read last. In each class, each meter is classified according to information representing a topology of the network having an influence on the failure risk of the transmissions of information by the meter. The concentrator accounts for the classification of the meters when the meters in the network are read to reduce occurrences of periods of contention.
