摘要： A power line configuration or topology may be determined by identifying metering nodes that have time-stamped voltage values that correlate with voltage values measured at a transformer or other metering nodes at substantially the same time. A correlation between the time-stamped voltage values may be calculated by, in some examples, comparing a difference of a first time-stamped voltage value of a meter and a second time-stamped voltage value of a transformer or the second metering node to a predetermined threshold. If the difference is below the threshold, the metering node may be determined to be connected to the transformer or second metering node by a power distribution line.

摘要： Techniques are disclosed by which RF mesh networks can identify utility distribution topologies by using power line communication combined with wireless networking to identify the mapping of transformers and other distribution equipment at a back office system server. At a specified time, an item of distribution equipment signals a unique identifier by introducing a phase shift in the electric power being delivered by that equipment. A meter node detects and decodes these temporal shifts to obtain an identifier of equipment supplying the power to it. Upon ascertaining this identification, the meter node sends an acknowledgment to thereby register with that equipment. The association of the particular customer's premises with the equipment is also sent to a back office system, to enable a map of the correspondence between meter and the equipment to be generated.

摘要： A time synchronization device (TSD) that produces a synchronization signal and couples it onto energized power conductors in a power monitoring system. Monitoring devices coupled to the TSD include frequency detection algorithms, such as a Goertzel filter, for detecting the synchronization signal and interpreting the information encoded in the signal. The frequency of the synchronization signal may correspond to the fourth or tenth harmonic component of the fundamental frequency of the voltage on the power conductors. The magnitude of the signal is selected to be above the expected or established noise floor of the power monitoring system plus a predetermined threshold. The duration of the signal can be varied, such as lasting a full cycle of the fundamental frequency. Multiple TSD signals received in a predetermined sequence may be converted into digital words that convey time, configuration, reset, control, or other information to the monitoring device.

摘要： Determination of a sensor device location in a sensor network is described. A system can include rotating optical beams (270) having a known location. Detectors (210) can be located with each of the rotating optical beams. The system can include a sensor device (280) placeable as part of the sensor network. A reflector (125, 285) can be near the sensor device and can reflect at least two optical beams back to the detectors associated with each of the respective optical beams. A triangulation module (235) can triangulate a position of the reflector, and thus the sensor, based on the reflected optical beams.
