Abstract

Systems and methods for utility meter data collection on distributed metering systems. One aspect of the present invention provides quantity-interval or count-step based collection, reading, recording, and/or transmission of consumption data for distributed utility meter reading systems.

Claims

1. A data collection system comprising:

a collector having a receiver configured to receive data; and

a plurality of sensors each of which is configured to determine an elapsed time between successive measurements of a predetermined quantity of a consumable commodity and send data comprising the elapsed time to the collector.

2. The system of claim 1, wherein the data sent by one or more of said plurality of sensors is transmitted by wireless radio frequency signal.

3. The system of claim 1, wherein said sensor sends said elapsed time to said collector for each measurement of said predetermined quantity.

4. The system of claim 1, wherein said sensor sends said elapsed time to said collector at intervals of the predetermined quantity.

34. The data collection system of claim 1 wherein each sensor is further configured to send data comprising a relatively-current total absolute value of utility consumed.

5. A data collection system for the collection of data from a plurality of commodity meters comprising:

a) a plurality of telemetry devices, each of the plurality of telemetry devices being associated with at least one selected meter, each telemetry device including;

i) a sensor to successively measure a predetermined amount of a parameter from said meter,

ii) a timer to measure the elapsed rime between each successive measurement of said predetermined amount said parameter;

iii) a first memory configured to store said elapsed times, and

iv) a sending module for sending a packet of a plurality of said stored elapsed times, the packet including an address unique to a certain telemetry device; and

b) a plurality of collection devices located remote from said telemetry devices for receiving the packet.

6. The system of claim 5 wherein the sending module consists of a wireless transmitter for transmitting said packet by a wireless signal for each measurement of a predetermined amount of said parameter.

35. The data collection system of claim 5, wherein the sending module of each telemetry device is configured to send data comprising a relatively-current total absolute value of utility consumed.

36. The data collection system of claim 35, wherein each packet of stored elapsed times further comprises the absolute value data.

7. A radio communication network for communicating information comprising a plurality of remote data generating stations, each of the remote stations having means for generating data for transmission, control means for modulating the data for transmission on a radio frequency carrier and arranged to form said data into a packet of data and to transmit said data upon each successive measurement of a predetermined amount of a consumable commodity.

37. The radio communication network of claim 7, wherein each packet of data arranged by the control means further comprises a relatively-current total absolute value of utility consumed.

8. A method of collecting data related to a metered commodity comprising the steps of:

successively measuring a predetermined amount of said metered commodity;

measuring the elapsed time between each successive measurement of said predetermined amount of said metered commodity; and

storing said elapsed time in a telemetry device.

9. The method of claim 8 further comprising transmitting by wireless signal said stored elapsed time to at least one collection device for each measurement of said predetermined amount of said metered commodity.

10. The method of claim 9 further comprising storing a plurality of elapsed times in said telemetry device.

11. The method of claim 10 further comprising:

extracting a series of elapsed times from said transmitted wireless signals; and

analyzing said series of elapsed times to generate a rate of use of said metered commodity.

12. A method of collecting commodity usage data comprising:

monitoring usage of a commodity at a utility meter;

determining the time that elapsed between the measurement of one or more set quantity intervals based on the usage monitored at the meter; and

recording data, wherein the data is based on the time elapsed during the one or more set quantity intervals.

13. The method of claim 12 wherein the data comprises the elapsed time.

14. The method of claim 12 further comprising transmitting the elapsed time associated with the most recent quantity interval along with one or more elapsed times associated with one or more previous quantity intervals.

15. The method of claim 12 further comprising transmitting one or more of the elapsed rime intervals at transmission intervals based on the quantity intervals.

16. The method of claim 12 wherein the one or more elapsed time intervals are transmitted to a remote collection system.

17. The method of claim 16 further comprising transmitting a meter ID to the remote collection system.

18. The method of claim 17 wherein the one or more elapsed time intervals and the Meter ID are transmitted together over a packet based transmission system.

19. The method of claim 12 wherein measured quantity data is also recorded after a predetermined maximum time interval has passed.

32. The method of claim 12 wherein determining the time that elapsed occurs at the utility meter.

33. The method of claim 12 wherein determining the time that elapsed occurs at a concentrator separate from the utility meter.

38. The method of claim 12 further comprising transmitting a relatively-current total absolute value of utility consumed along with one or more elapsed times.

41. The method of claim 12 further comprising storing the data at the utility meter.

20. A utility meter data collection system comprising:

a meter-reading device configured to record data associated with intervals, wherein the lengths of the intervals are based at least in part on the quantity of the commodity that is consumed and the data comprises a determined elapsed time for one or more of the intervals, and the meter reading device is configured to send the data to a concentrator; and

a concentrator for collecting data from the meter-reading device.

21. The system of claim 20 wherein the determined elapsed time is the change in time that occurs while a set quantity of the utility is consumed.

22. The system of claim 20 wherein the meter-reading device is configured to send data about previous quantity intervals with data about the current quantity interval.

23. The system of claim 20 wherein the data transmitted to the collection system comprises a meter ID associated with the meter and information about the change in time that occurs while the set quantity of the commodity is consumed.

24. The system of claim 20 wherein the data is transmitted in a packet over a packet based transmission system.

25. The system of claim 20 wherein the lengths of the intervals are also based at least in part on whether a predetermined maximum time interval has passed without a set quantity of the commodity being consumed.

27. The method of claim 25 further comprising using the profile for analysis.

28. The method of claim 25 further comprising using the profile for billing.

29. The method of claim 25 further comprising using the profile to generate statistics regarding consumer usage patterns.

30. The method of claim 25 further comprising using the profile to allow billing a consumer based on time of use.
