Abstract

Packet formats and associated metering infrastructure for filtering meter reading data that is being transmitted by utility meters are disclosed. In one embodiment, a method suitable for being implemented in a metering environment is provided that filters meter reading data being received by multiple collectors. Specifically, the method includes ranking the relative ability of the plurality of collectors to capture transmissions from the same utility meter. Based on the relative ranking, at least one collector from the plurality of collectors is identified that will be configured to disregard transmissions that originate from the utility meter. Then, the method provides the collector with a read list for differentiating between transmissions containing meter reading data that will be forwarded to a utility service provider from transmissions that originate from the utility meter.

Claims

1. In a metering environment that includes a plurality of collectors and a utility meter, a method of filtering data that is transmitted from the utility meter, comprising:

ranking the relative ability of the plurality of collectors to capture transmissions from the utility meter;

based on the relative ranking, identifying at least one collector from the plurality of collectors that will be configured to disregard transmissions that originate from the utility meter; and

providing the at least one collector with network configuration information for differentiating between transmissions containing data that will be forwarded to a utility service provider from transmissions that originate from the utility meter.

2. The method as recited in claim 1, further composing:

at the at least one collector, obtaining a transmission that includes a packet; and

comparing the network configuration represented in the received packet with the network configuration provided to the at least one collector to determine whether the packet contains meter reading data being reported by the utility meter.

3. The method as recited in claim 1, wherein ranking the relative ability of the plurality of collectors to capture transmissions from the utility meter, includes:

using the plurality of collectors to obtain a sample set of transmissions from the utility meter; and

generating a metric that measures the ability of the at least one collector to obtain transmissions from the utility meter.

4. The method as recited in claim 3, wherein using the plurality of collectors to obtain a sample set of transmissions from the utility meter includes causing data obtained by the plurality of collectors to be aggregated at a central location.

5. The method as recited in claim 3, wherein generating a metric includes calculating a read coefficient that quantifies the number of transmissions obtained by the at least one collector relative to the total number of packets broadcast by the utility meter in the sample.

6. The method as recited in claim 1, wherein identifying at least one collector that will be configured to disregard transmissions that originate from the utility meter includes causing the value of network configuration information in packets originating from the utility meter to be modified.

7. A system for filtering meter reading data that is transmitted to a utility service provider, the system comprising:

a utility meter configured to encode and transmit packets that include a network configuration associated with the utility meter;

a host server operative to obtain a sample of meter reading data originating from the utility meter and define a network configuration for at least one collector to disregard packets that originate from the utility meter; and

a collector configured to obtain a packet transmitted by the utility meter and compare the network configuration represented in a received packet with the network configuration defined by the host server to determine whether to collect meter reading data in the received packet.

8. The system as recited in claim 7, wherein the collector is further configured to utilize the two-way communication ability of the utility meter to modify the value of network configuration information included in packets that are transmitted by the utility meter.

9. The system as recited in claim 7, wherein the host server is further configured to rank the relative ability of a plurality of collectors to capture packets transmitted by the utility meter.

10. The system as recited in claim 7, further comprising a second utility meter wherein the host server is further configured to define a network configuration for the collector to listen for packets that originate from the second utility meter and the collector is further configured to forward meter reading data received from the second utility meter to the host server.

11. A collector configured to filter meter reading data having instructions that, when executed by a processor, causes the collector to:

accept a network configuration to disregard packets originating from a first utility meter;

receive a packet that includes a representation of a network configuration associated with a utility meter that encoded the packet;

compare the network configuration represented in the packet with the network configuration of the collector; and

if the result of the comparison indicates that the packet originated from the first utility meter, prevent meter reading data encoded in the packet from being forwarded to a remote device.

12. The collector as recited in claim 11, wherein the collector is further configured to accept a network configuration to listen for packets originating from a second utility meter and wherein if the result of the comparison indicates that the packet originated from the second utility meter, the collector is further configured to forward meter reading data in the packet to the remote device.

13. The collector as recited in claim 12, wherein to accept a network configuration to listen for packets originating from a second utility meter includes utilizing the two-way communication ability of the second utility meter to modify the network configuration information represented in packets encoded by the second utility meter.

14. The collector as recited in claim 12, wherein to forward meter reading data in the packet includes aggregating meter reading data received from multiple utility meters and converting the aggregated data into a format accepted by a utility service provider.

15. The collector as recited in claim 11, wherein the network configuration accepted by the collector is defined based on the relative ability of a plurality of collectors to capture packets originating from the first utility meter.

16. The collector as recited in claim 15, wherein to define the network configuration of the collector includes calculating a metric that measures the ability of the collector to obtain packets from the first utility meter.
