System and method for power outage and restoration notification in an advanced metering infrastructure network
View Patent ↗A method and system are provided to transmit a meter power status. The method includes recognizing a power status change at a meter. The method includes, if the meter is scheduled to transmit first, transmitting a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier. The method includes, if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter. The method includes, responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter. The method includes retransmitting the notification message.
1. A method of transmitting a meter power status, comprising:
recognizing a power status change at a meter;
if the meter is scheduled to transmit first, transmitting a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier;
if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter;
responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter;
retransmitting the notification message; and
responsive to a first failure to receive an acknowledgement from the at least one neighboring meter, retransmitting the notification message over an alternative mesh network path;
responsive to a second failure to receive an acknowledgement from the at least one neighboring meter, retransmitting the notification message through a newly discovered mesh network path; and
responsive to a third failure to receive an acknowledgement from the at least one neighboring meter, associating with a new mesh network and retransmitting the notification message over the new mesh network.
2. The method of claim 1 , wherein the power status change is at least one of: a power outage and a power restoration.
3. The method of claim 1 , further comprising:
waiting a random time period before retransmitting the notification message.
4. The method of claim 1 , wherein the meter is scheduled to transmit first if it has a high number of hops from the mesh gate.
5. The method of claim 1 , wherein the meter is scheduled to transmit first if it is a leaf node in a mesh network.
6. The method of claim 1 , wherein the meter communicates with neighboring meters via a mesh network.
7. A system for transmitting a network power status, comprising:
(A) a mesh network;
(B) a wide area network separate from the mesh network;
(C) at least one meter in communication with the mesh network, the meter configured to:
recognize a power status change at a meter,
if the meter is scheduled to transmit first, transmit a notification message to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier,
if the meter is not scheduled to transmit first, wait a predetermined time period to receive a notification message from at least one neighboring meter,
responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, and
retransmitting the notification message;
(D) a mesh gate in communication with the meter over the mesh network and in communication with the wide area network, the mesh gate configured to:
receive at least one notification message from a meter, wherein the notification messages include a power status indicator and at least one meter identifier,
aggregate the received meter identifiers into a composite notification message, the composite notification message include a power status indicator and at least one meter identifier,
transmit the composite notification message to a server over a wide area network, and
retransmitting the composite notification message; and
(E) a server in communication with the mesh gate over the wide area network, the server configured to receive the composite notification message.
8. The system of claim 7 , wherein the power status change is at least one of: a power outage and a power restoration.
9. The system of claim 7 , wherein the meter is scheduled to transmit first if it has a high number of hops from the mesh gate.
10. The system of claim 7 , wherein the meter is scheduled to transmit first if it is a leaf node in a mesh network.
11. The system of claim 7 , wherein the mesh gate is further configured to select an isolated outage reporting configuration or a major outage reporting configuration, wherein the major outage reporting configuration includes a longer aggregation window.
12. The system of claim 7 , wherein the mesh gate does not retransmit the composite notification message during an exclusion period.
13. A method of transmitting a meter power status, comprising:
recognizing a power status change at a meter;
if the meter is scheduled to transmit first, transmitting a notification message from the meter to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier;
if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter;
responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, wherein the notification message include a power status indicator and at least one meter identifier;
aggregating the received meter identifiers into a composite notification message, the composite notification message including a power status indicator and at least one meter identifier;
transmitting the composite notification message to a server over a wide area network; and
retransmitting the composite notification message.
14. A computer program stored in a computer readable form for execution in a processor and a processor coupled memory to implement a method of transmitting a meter power status, the method comprising:
recognizing a power status change at a meter;
if the meter is scheduled to transmit first, transmitting a notification message from the meter to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier;
if the meter is not scheduled to transmit first, waiting a predetermined time period to receive a notification message from at least one neighboring meter;
responsive to receiving a notification message, adding a meter identifier to the received notification message before retransmitting the modified notification message to at least one neighboring meter, wherein the notification message include a power status indicator and at least one meter identifier;
aggregating the received meter identifiers into a composite notification message, the composite notification message including a power status indicator and at least one meter identifier;
transmitting the composite notification message to a server over a wide area network; and
retransmitting the composite notification message.
