Abstract

An energy monitor for monitoring energy consumed by each of a plurality of energy consuming devices is disclosed. The energy monitor comprises a processor, a memory, means for storing energy usage rate data in the memory, the energy usage rate data representing a rate of energy consumed by each of the devices, means for determining when each of the devices is operating, means responsive to the storing means and the determining means for calculating energy consumption numbers representing a quantity of energy consumed by each device while each of the devices is operating and means for selectively displaying each of the energy consumption numbers.

Claims

1. An energy monitor for individually monitoring first and second energy consuming devices which produce signals when operating, said devices having respective first and second rates of energy usage, said energy monitor comprising:

a processor;

means associated with said processor for storing energy usage rate data, said data representing individual rates of energy consumption for each of said devices;

means associated with said processor and responsive to said signals for separately providing cumulative running time information for each of said devices;

means associated with said providing means and said storing means for separately producing cumulative energy consumption information for each of said devices; and

means associated with said producing means for separately indicating said energy consumption information for each of said devices.

2. The energy monitor of claim 1 wherein said energy consumed by at least one of said devices comprises gas, and said energy consumption information for said device represents therms of gas consumed.

3. The energy monitor of claim 1 wherein said energy consumed by at least one of said devices comprises electricity, and said energy consumption information for said device represents kilowatt-hours of electricity consumed.

4. The energy monitor of claim 1 wherein said cumulative running time information for each of said devices is in the form of operating time numbers representing separate total times that each of said devices is operated, and further including means for separately displaying said operating time numbers for each of said devices.

5. The energy monitor of claim 1 further including:

means associated with said processor for storing budget data, said budget data representing individual budgeted quantities of energy to be consumed by each of said devices;

means associated with said means for storing budget data and said producing means for providing remaining budgeted energy information, said remaining budgeted energy information representing individual remaining quantities of energy allowed to be consumed by each of said devices; and

means for separately displaying said remaining budgeted energy information for each of said devices.

6. The energy monitor of claim 5 further including means for selectively alternately displaying said energy consumption information and said remaining budgeted energy information for each of said devices.

7. An energy monitor for individually monitoring first and second energy consuming devices which produce individual operating signals, said devices having respective first and second rates of energy usage, said energy monitor comprising:

input means for providing separate interface signals in response to said operating signals;

computer means responsive to said interface signals for accumulating individual running time information for each of said devices, for storing energy usage rate data, said date representing individual rates of energy consumption for each of said devices, and responsive to said stored energy usage rate data and said accumulating running time information for generating separate cumulative energy consumption information for each of said devices; and

output means for separately providing an indication of said energy consumption information for each of said devices.

8. The energy monitor of claim 7 wherein the accumulated individual running time information for each of said devices is in the form of operating time numbers representing separate total times that each of said devices is operated, and said energy monitor further including means for separately displaying said operating time numbers for each of said devices.

9. The energy monitor of claim 7 wherein the computer means is also for storing budget data, said budget data representing individual budgeted quantities of energy to be consumed by each of said devices, and is responsive to said stored budget data and said cumulative energy consumption information for providing remaining budgeted energy information, said remaining budgeted energy information representing individual remaining quantities of energy allowed to be consumed by each of said devices;

and

said energy monitor further including output means for separately displaying said remaining budgeted energy information for each of said devices.

10. A method for individually monitoring first and second energy consuming devices which produce operating signals, said devices having respective first and second rates of energy uses, said method comprising:

providing interface signals in response to said operating signals;

accumulating separate running time information from said interface signals for each of said devices;

storing energy usage rate data, said data representing individual rates of energy consumption for each of said devices generating separate cumulative energy consumption information for each of said devices; and

providing an indication of said energy consumption information for each of said devices.

11. The method as recited in claim 10 wherein the step of accumulating separate running time information includes providing the accumulated running time information in the form of operating time numbers representing separate total times that each of said devices is operated, and said method further including the step of separately displaying said operating time numbers for each of said devices.

12. The method as recited in claim 10 further including the steps of:

storing budget data, said budget data representing individual budgeted quantities of energy to be consumed by each of said devices;

providing remaining budgeted energy information, said remaining budgeted energy information representing individual remaining quantities of energy allowed to be consumed by each of said devices; and

separately displaying said remaining budgeted energy information for each of said devices.
