    摘要： A communication device detects 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 nodes in the 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 network during a predetermined time period, based on a condition and/or event occurring during the time period. The communication device receives operation data from nodes in the network, and determines whether the operation data from a node 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.

    摘要： Following an explosion, fire, flood, water damage, or other event, consumption data of utility resources such as gas and water may be used to determine a cause of the event. For example, an interrogation may be used to read data logging data from a data collection device. The data logging data may include a record of consumption data for a resource spanning a time of an event. The data logging data may be analyzed to determine whether a utility providing the resource was responsible for the event.

    摘要： In an electric network (1) which comprises an upstream supply (2) and at least two downstream outlets, the supply and the outlets are each provided with a sensor (6) for measuring an extensive electric quantity and each sensor conducts, in a synchronous way with the other sensors, a measurement of this quantity depending on a parameter. This method comprises at least N measurements of the value on the upstream supply and on each downstream outlet conducted for different values of the parameter p. Then, the relationship between the measurements is formalized, for each value of the parameter p with the equation: M  ( p j ) = ∑ i = 1 N  a i  m i  ( p j ) A system with N equations and N unknowns is generated, the unknowns being the gains ai, the system of equations is solved, by calculating each gain, and the gains are controlled. If all the gains are equal to 1, it is considered that no sensor has conducted a faulty measurement. If at least one of the gains is different from 1, it is considered that at least one sensor has conducted a faulty measurement.
