Abstract

An automated meter reading system having an image obtaining device, mounted to the outside of a conventional meter, and a central station for receiving and processing images from the image obtaining device. The image obtaining device lies dormant until its internal circuitry recognizes that it is time to obtain an image of the meter'"'"'s readout. Once the image is obtained, the image is transmitted to the central station, which processes the image to obtain billing and other information.

Claims

1. An automated meter reading device comprising:

an imaging device;

a timer, said timer generating a first signal when a predetermined time expires;

a controller being activated by the first signal and causing the imaging device to obtain an image of a display area of the meter, said controller inputting the image from said imaging device; and

a communication interface for transmitting the image to an external device.

2. The meter reading device of claim 1,wherein said meter reading device is powered by a battery.

3. The meter reading device of claim 1, further comprising a light emitting diode, said light emitting diode being activated by the controller when the image is being obtained.

4. The meter reading device of claim 1, wherein said meter reading device is mounted to an outside of the meter.

5. The meter reading device of claim 1, wherein said controller resets said timer and enters a power down mode after the image is transmitted.

6. The meter reading device of claim 5, wherein said controller resets said timer based on a command from the external device.

7. The meter reading device of claim 1, wherein said imaging device is one of a CMOS imager and CCD imager.

8. The meter reading device of claim 1, wherein said controller comprises a processor and said imaging device and processor are contained on the same integrated circuit.

9. The meter reading device of claim 1, wherein the communication interface comprises means for wireless communications.

10. The meter reading device of claim 9, wherein said wireless communications means comprises a wireless Internet communication network.

11. The meter reading device of claim 9, wherein said wireless communications means comprises satellite communications.

12. The meter reading device of claim 9, wherein said wireless communications means comprises radio frequency communications.

13. The meter reading device of claim 1, wherein the communication interface comprises a wired communication.

14. The meter reading device of claim 1, further comprising an antenna directly connected to said communication interface, wherein a transmitter portion of said communication interface and said antenna are separable from said meter reading device.

15. An automated meter reading device comprising:

a housing;

a mount for mounting said housing to a meter;

a timer within said housing, said timer generating a first signal when a predetermined time expires;

a controller within said housing being activated by the first signal and causing the imaging device to obtain an image of a display area of the meter, said controller inputting the image from said imaging device; and

a communication interface within said housing for transmitting the image to an external device.

16. The meter reading device of claim 15, further comprising a light emitting diode within a wall of said housing, said light emitting diode being activated by the controller when the image is being obtained.

17. The meter reading device of claim 15, wherein said controller resets said timer and enters a power down mode after the image is transmitted.

18. The meter reading device of claim 17, wherein said controller resets said timer based on a command from the external device.

19. The meter reading device of claim 15, wherein the communication interface comprises means for wireless communications.

20. The meter reading device of claim 15, wherein the communication interface comprises a wired communication.

21. An automated meter reading system comprising:

an automated image obtaining and sending device comprising;

a housing,

a mount for mounting said housing to a meter,

a timer within said housing, said timer generating a first signal when a predetermined time expires,

a first processor within said housing being activated by the first signal and causing the imaging device to obtain an image of a display area of the meter, said first processor inputting the image from said imaging device, and

a first communication interface within said housing for transmitting the image; and

a central station comprising;

a second communication interface for receiving the transmitted image from the first communication interface, and

a second processor for recognizing a pattern in the image and using the pattern to determine a value of the meter display area.

22. The system of claim 21, wherein said automated image obtaining and sending device further comprises a light emitting diode within a wall of said housing, said light emitting diode being activated by the controller when the image is being obtained.

23. The system of claim 21, wherein said first processor resets said timer and enters a power down mode after the image is transmitted.
