Abstract

A display system that communicates with existing automated meter reading communications systems to provide information to a user. The display includes a radio that listens to communications between a utility meter and the reading system. When the display recognizes a particular utility meter identifier, it captures meter read information and stores it in memory. The information may then be presented to the user. Alternatively, a broadcast message may be communicated, that when received by the display, causes the display to extract information from the receiver. A manual override button may be provided to allow a user to manually request information from the meter. The display will extract information from the meter upon receipt of the manual request.

Claims

1. A method of providing commodity consumption information to a user via a remote display, comprising:

communicating with a utility meter associated with the remote display, wherein the associated utility meter is part of a wireless network comprising a collector and a plurality of utility meters that bi-directionally communicate wirelessly with the collector, each of the utility meters having a wireless communication path to the collector that is either a direct communication path to the collector or an indirect communication path through one or more other utility meters that serve as repeaters, and the collector receiving commodity consumption information from the plurality of utility meters;

wirelessly retrieving commodity consumption information from the associated utility meter by the remote display in response to a message from the collector received by the remote display, wherein the message received from the collector controls the time at which commodity consumption information is retrieved from the associated utility meter by the remote display; and

updating the remote display with said commodity consumption information.

2. The method of claim 1, further comprising maintaining a duplicate copy of configuration information of said utility meter.

3. The method of claim 2, said configuration information comprising at least one of time synch, tier pricing, and a TOU schedule.

4. The method of claim 1, wherein said communicating with said associated utility meter comprises:

recognizing an identifier of said associated utility meter; and

updating memory with current meter read information from said associated utility meter.

5. The method of claim 1, wherein the message received from the collector is broadcast by the collector via the wireless network.

6. The method of claim 1, wherein the message received from the collector is wirelessly transmitted by the collector on a frequency that is not used by the utility meters of the automated meter reading system to bi-directionally communicate with the collector.

7. The method of claim 1, further comprising retrieving commodity consumption information from said associated utility meter in response to receipt of a manual read request.

8. The method of claim 7, further comprising:

providing a user interface on said display in response to said manual read request; and

providing a selection of types of information to be retrieved by said display in response to a user input.

9. The method of claim 1, further comprising:

manipulating said commodity consumption information to determine supplemental information, said supplemental information comprising at least one of projected commodity usage, a bill for a predetermined time period, and a comparison of commodity usage for first period versus a second period.

10. A remote display that communicates with an automated meter reading system, the automated meter reading system comprising a collector and a plurality of utility meters that bi-directionally communicate wirelessly with the collector, each of the utility meters having a wireless communication path to the collector that is either a direct communication path to the collector or an indirect communication path through one or more other utility meters that serve as repeaters, and the collector receiving commodity consumption information from the plurality of utility meters, the remote display comprising:

memory for storing commodity consumption data;

firmware containing executable instructions for receiving commodity consumption data from an associated utility meter of said automated meter reading system;

a microcontroller; and

a radio adapted to retrieve commodity consumption data from the utility meter associated with the remote display in response to a message received from the collector of said automated meter reading system, wherein the message received from the collector controls the time at which commodity consumption information is retrieved from the associated utility meter by the remote display.

11. The display as recited in claim 10, wherein the message received from the collector is wirelessly transmitted by the collector on a frequency that is not used by the utility meters of the automated meter reading system to bi-directionally communicate with the collector.

12. The display as recited in claim 11, wherein the message received from the collector is broadcast by the collector via the wireless network.

13. The display as recited in claim 10, farther comprising a manual read control, wherein said commodity consumption information is retrieved from said associated utility meter in response to receipt of an input via said manual read control.

14. The display as recited in claim 10, wherein said automated meter reading system utilizes Frequency Hopping Spread Spectrum (FHSS) communications having a predetermined number of channels, and wherein said radio utilizes a first subset of said number of channels in which to communicate with said utility meter.

15. The display as recited in claim 14, wherein said display communicates with said automated meter reading system utilizing a second subset of said number of channels, said second subset of channels not intersecting said first subset of channels.

16. An automated meter reading system comprising:

a collector;

a plurality of utility meters that bi-directionally communicate wirelessly with the collector, each of the utility meters having a wireless communication path to the collector that is either a direct communication path to the collector or an indirect communications path through one or more other utility meters that serve as repeaters, the plurality of utility meters transmitting commodity consumption data to the collector and the collector transmitting control information to the utility meters; and

at least one in-home remote display device comprising;

memory for storing commodity consumption data;

firmware containing executable instruction for receiving commodity consumption data from an associated utility meter of said automated meter reading system;

a microcontroller; and

a radio adapted to retrieve commodity consumption data from the utility meter associated with the remote display in response to a message received from the collector of said automated meter reading system, wherein the message received from the collector controls the time at which commodity consumption information is retrieved from the associated utility meter by the remote display.

17. The display as recited in claim 16, wherein the message received from the collector is wirelessly transmitted by the collector on a frequency that is not used by the utility meters of the automated meter reading system to bi-directionally communicate with the collector.

18. The display as recited in claim 16, wherein the message received from the collector is broadcast by the collector via the wireless network.

19. The display as recited in claim 16, further comprising a manual read control, wherein said commodity consumption information is retrieved from said associated utility meter in response to receipt of an input via said manual read control.

20. The display as recited in claim 16, wherein said automated meter reading system utilizes Frequency Hopping Spread Spectrum (FHSS) communications having a predetermined number of channels, and wherein said radio utilizes a first subset of said number of channels in which to communicate with said utility meter.

21. The display as recited in claim 20, wherein said display communicates with said automated meter reading system utilizing a second subset of said number of channels, said second subset of channels not intersecting said first subset of channels.
