Network event detection

摘要

Various aspects of the disclosure are directed to methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying network events. In one aspect, a method includes monitoring signal characteristic values for signals transmitted over a communications channel of a power line communications system and determining that a signal level value for the channel is less than a threshold signal level value for the channel. In response to determining that the signal level value for the channel is less than the threshold signal level value for the channel, a signal to noise ratio for the communications channel is computer and it is determined that the signal to noise ratio for the channel exceeds a threshold value. In response to determining that the signal to noise ratio for the communications channel exceeds the threshold value, storing data received over the communications channel is stored as valid data.

1. A method performed by data processing apparatus, the method comprising:
for each of a plurality of communications channels of a power line communications system implemented in a power-line distribution system:
monitoring, by logic circuitry, signal characteristic values for a set of signals transmitted over one of the communications channels over a segment of time and determining, based on the monitored signal characteristic values, whether a signal level value for the set of signals is below a threshold level corresponding to a threshold signal level value for the communications channel and whether a noise parameter for the set of signals is less than another threshold level corresponding to a measure of data validity;in response to the step of determining, storing, by the data processing apparatus, data received over said one of the communications channels as valid data, and providing an update that a circuit in the power-line distribution system has changed; and in response to the step of determining:
determining that a capacitor bank has been activated in the power-line distribution system, andproviding a notification that the capacitor bank has been activated in the power-line distribution system.
