Abstract

A remote unit includes an electronics assembly, a housing, and a fastening member. The electronics assembly includes a communications module and an image sensor, having a lens with a field of view, that captures images of a display of a meter. The housing includes a cover coupled to a base member. The base member couples to the meter and includes an aperture. The electronics assembly is retained between the base member and the cover, such that the lens aligns with the aperture. The fastening member receives a portion of the housing in a hollow section. A mechanism of the fastening member attaches to a portion of the meter, maintaining the display in the field of view. The communications module transmits image data, derived from the captured images, to a hub unit. The hub unit processes the image data, and forwards information extracted from the image data to a remote server.

Claims

1. A system for reading a meter that includes a display area covered by a display cover, the system comprising:

a remote unit including;

an electronics assembly retained in a housing for communicating with the display cover of the meter, the electronics assembly including an image sensor for capturing images of the display area of the meter, and a remote unit communications module configured to transmit, over a broadband communications channel, image data derived from the images captured by the image sensor, and

a fastening member for coupling the electronics assembly to the meter by passing a top portion of a cover of the housing through a hollow section of the fastening member so as to bring a base member of the housing into communication with the display cover, such that a lens of the image sensor is aligned with an aperture of the housing to view the display area of the meter through the aperture; and

a server remotely located from the remote unit, the server configured to;

receive the transmitted image data from the remote unit communications module over the broadband communications channel, and

compare an identifier of the meter, extracted from the received image data by processing the image data, with a stored identifier associating the remote unit with the meter.

2. The system of claim 1, wherein the server is further configured to send a programmable transmit and receive schedule for the remote unit communications module, and wherein the remote unit communications module is configured to operate according to the programmable transmit and receive schedule.

3. The system of claim 1, wherein the remote unit communications module is configured to transmit an image captured by the image sensor in response to a request sent by the server.

4. The system of claim 1, wherein the electronics assembly further includes a remote unit processing unit including at least one processor coupled to a storage medium, the remote unit processing unit configured to derive the image data by compressing the images captured by the image sensor.

5. The system of claim 1, wherein the electronics assembly further includes a tampering sensor arrangement, and wherein the remote unit is configured to generate a tamper warning message, in response to input from the tampering sensor arrangement, for receipt by the server.

6. The system of claim 1, wherein the electronics assembly further includes a power supply and a power monitor operatively coupled to the power supply, and wherein the remote unit is configured to send power status information, in response to input from the power monitor, for receipt by the server.

7. The system of claim 1, wherein the server is operated in cooperation with a utility service provider.

8. The system of claim 1, wherein the server is an Internet of Things (IoT) server.

9. The system of claim 1, wherein the meter is deployed to measure consumption of a commodity.

10. The system of claim 9, wherein the commodity is a fluid.

11. The system of claim 10, wherein the fluid is water.

12. The system of claim 10, wherein the fluid is a gas.

13. The system of claim 9, wherein the commodity is electricity.

14. The system of claim 1, wherein the processing the image data includes performing optical character recognition.

15. A method for reading a meter that includes a display area covered by a display cover, the method comprising:

deploying a remote unit, the remote unit including a housing having an electronics assembly retained therein, the electronics assembly including an image sensor, the deploying including passing a top portion of a cover of the housing through a hollow section of a fastening member so as to bring a base member of the housing into communication with the display cover, such that a lens of the image sensor is aligned with an aperture of the housing to view the display area of the meter through the aperture;

capturing, by the image sensor, at least one image of the display area of the meter;

receiving image data at a server remotely located from the remote unit, the image data derived from the at least one image captured by the image sensor; and

comparing an identifier of the meter, extracted from the received image data, with a stored identifier associating the remote unit with the meter.

16. The method of claim 15, further comprising:

sending, by the server, a programmable transmit and receive schedule to the remote unit communications module.

17. The method of claim 16, further comprising:

operating the remote unit according to the programmable transmit and receive schedule.

18. The method of claim 15, further comprising:

sending, by the server, an image capture request to the remote unit.

19. The method of claim 18, further comprising:

capturing, by the image sensor, at least one image of the display area of the meter in response to the image capture request sent by the server.

20. A system for reading a plurality of meters, each meter including a display area covered by a display cover, the system comprising:

a plurality of remote units, each remote unit corresponding to a different respective meter and including;

an electronics assembly retained in a housing, the electronics assembly including an image sensor for capturing images of the display area of the meter, and a remote unit communications module configured to transmit, over a broadband communications channel, image data derived from the images captured by the image sensor, and

a fastening member for coupling the electronics assembly to the meter by passing a top portion of a cover of the housing through a hollow section of the fastening member so as to bring a base member of the housing into communication with the display cover, such that a lens of the image sensor is aligned with an aperture of the housing to view the display area of the meter through the aperture; and

a server remotely located from the remote units, the server configured to;

receive the transmitted image data from each of the remote unit communications modules over the broadband communications channel, and

for each of the remote units, compare an identifier of the meter, extracted from the received image data, with a stored identifier associating the remote unit with the meter.
