Abstract

Methods, systems, and products are disclosed for interfacing with a power line network. Electrical power is received, and a voltage of the electrical power is monitored. When the voltage is inadequate, then an alternate power source is automatically connected. A frequency of electrical power provided by the alternate power source is monitored, and high frequency data signals are separated from low frequency power signals.

Claims

1. A method, comprising:

receiving electrical power from a power line network;

monitoring a voltage of the electrical power received from the power line network;

connecting an alternate power source in response to the voltage being inadequate;

monitoring a frequency of the electrical power provided by the alternate power source; and

separating high frequency data signals from low frequency power signals.

2. The method according to claim 1, further comprising distributing the high frequency data signals.

3. The method according to claim 1, further comprising connecting to a meter.

4. The method according to claim 1, further comprising connecting to an electrical outlet.

5. The method according to claim 1, wherein receiving the electrical power from the power line network comprises receiving the electrical power from an electrical distribution panel.

6. The method according to claim 1, further comprising distributing packets of data.

7. The method according to claim 1, further comprising remotely monitoring the voltage of the electrical power received from the power line network.

8. The method according to claim 1, further comprising remotely monitoring the frequency of the electrical power provided by the alternate power source.

9. The method according to claim 1, further comprising modulating the high frequency data signals.

10. The method according to claim 1, further comprising converting an IP address.

11. A system, comprising:

a processor; and

memory storing code that when executed causes the processor to perform operations, the operations comprising;

receiving electrical power from a power line network;

monitoring a voltage of the electrical power received from the power line network;

connecting an alternate power source in response to the voltage being inadequate;

monitoring a frequency of the electrical power provided by the alternate power source; and

separating high frequency data signals from low frequency power signals.

12. The system according to claim 11, wherein the operations further comprise distributing the high frequency data signals.

13. The system according to claim 11, wherein the operations further comprise connecting to a meter.

14. The system according to claim 11, wherein the operations further comprise connecting to an electrical outlet.

15. The system according to claim 11, wherein the operations further comprise receiving the electrical power from an electrical distribution panel.

16. The system according to claim 11, wherein the operations further comprise distributing packets of data.

17. The system according to claim 11, wherein the operations further comprise communicating the voltage of the electrical power received from the power line network to a remote location.

18. The system according to claim 11, wherein the operations further comprise communicating the frequency of the electrical power provided by the alternate power source to a remote location.

19. The system according to claim 11, wherein the operations further comprise demodulating the high frequency data signals.

20. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising:

receiving electrical power from a power line network;

monitoring a voltage of the electrical power received from the power line network;

connecting an alternate power source in response to the voltage being inadequate;

monitoring a frequency of electrical power provided by the alternate power source; and

separating high frequency data signals from low frequency power signals.
