Power outage verification

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting a power outage. In one aspect, a status request requesting a status of a portion of a power distribution network is received, where the request includes a reference to a power meter that is located within the portion of the network. In response to the status request, a block of communications channels is selected, where the block includes a target communications channel over which a signal corresponding to the referenced power meter is received. In turn, an amplitude of the signal being received over the target communications channel is obtained. A determination is made whether the amplitude of the signal is less than an outage threshold and a status notification is provided that specifies the status of the portion of the power distribution network for which the status has been requested.

主权项

1. A computer-implemented method, comprising:
receiving, by a data processing apparatus, including a circuit, coupled to a memory device, a status request requesting a status of a first portion of a power distribution network, the status request including a reference to a referenced power meter that is located within the first portion of the power distribution network for which the status is requested; selecting, by the data processing apparatus, a block of communications channels that includes a target communications channel, at a center channel frequency relative to other communication channels in the block and with communication channels of the block on either side of the center channel frequency, over which a signal corresponding to the referenced power meter is received; obtaining, by the data processing apparatus, an amplitude of the signal being received over the target communications channel; determining, by the data processing apparatus, whether the amplitude of the signal being received over the target communications channel is less than an outage threshold for the target communications channel; and in response to determining whether the amplitude of the signal being received over the target communications channel is less than the outage threshold for the target communications channel, providing, by the data processing apparatus, a status notification that specifies the status of the first portion of the power distribution network for which the status has been requested.
