Abstract
A utility meter includes an energy storage device configured to store energy to run the utility meter after a primary source of energy to the utility meter is unable to provide sufficient energy to run the utility meter. The utility meter includes a processor configured to determine utility usage data associated with a utility consumer, monitor an energy level of the energy storage device, and save the utility usage data, a reduced set of the utility usage data, or both, depending on the energy level of the energy storage device, and at least one data storage device configured to store the utility usage data, the reduced set of the utility usage data, or both.
Claims20
A utility meter comprising:
- an energy storage device configured to store energy to run the utility meter after a primary source of energy to the utility meter is unable to provide sufficient energy to run the utility meter;
- a processor configured to:
- determine utility usage data associated with a utility consumer;
- monitor an energy level of the energy storage device;
- and
- save the utility usage data, a reduced set of the utility usage data, or both, depending on the energy level of the energy storage device;
- and
- at least one data storage device configured to store the utility usage data, the reduced set of the utility usage data, or both.
A non-transitory computer-readable medium having code stored thereon executable by a processor, the code comprising instructions to:
- collect utility usage data;
- monitor an energy level of an energy storage device, wherein the energy storage device is configured to provide energy to operate the processor;
- save a first set of the utility usage data incrementally and periodically when the energy level exceeds a first threshold;
- and
- save a incremental set of the utility usage data when the energy level falls beneath a second threshold, wherein the incremental set of the utility usage data comprises a reduced set of the utility usage data, and wherein the incremental set of the utility usage data is configured to enable a reconstruction of the utility usage data by combining the saved incremental set and the saved first set of the utility usage data.
A method comprising:
- receiving utility data in a utility meter;
- monitoring an energy level of an energy storage device using the utility meter, wherein the energy storage device is configured to provide energy to operate at least some components of the utility meter;
- and
- operating the utility meter in a power up mode when the energy level is above a threshold and operating the utility meter in a power down mode when the energy level is below a second threshold;
- wherein:
- operating the utility meter in the power up mode comprises occasionally performing an incremental save of a more detailed set of the utility data;
- and
- operating the utility meter in the power down mode comprises performing an incremental save of less detailed set of the utility data substantially immediately after the energy level falls below the second threshold.
