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 device for reading a meter that includes a display area covered by a display cover, the device comprising:

an electronics assembly including an image sensor for capturing an image of the display area of the meter, the image sensor including a lens having a field of view;

a housing including a cover coupled to a base member including an aperture, the base member for communicating with the display cover of the meter, the electronics assembly being retained between the base member and the cover such that the lens is aligned with the aperture; and

a fastening member including a hollow section accommodating a top portion of the cover to pass therethrough, the fastening member further including a mechanism for attaching the fastening member to a portion of the meter so as to maintain the display area of the meter in the field of view of the lens and bring the base member into communication with the display cover.

2. The device of claim 1, wherein the electronics assembly further includes a processing unit and a communications module, the processing unit for compressing the image captured by the image sensor, and the communications module for transmitting the compressed image to a hub unit over a wireless communication channel.

3. The device of claim 2, wherein the wireless communication channel is a radio frequency (RF) channel.

4. The device of claim 2, further comprising:

an antenna coupled to the communications module, the antenna partially encircling a printed circuit board of the electronics assembly and held in place by engagement of the base member with the cover.

5. The device of claim 2, wherein the electronics assembly further includes a printed circuit board (PCB), and wherein the image sensor, the processing unit and the communications module are attached to the PCB.

6. The device of claim 5, wherein the cover is transparent, and wherein the PCB is dimensioned to allow visibility of the display area of the meter, through the cover, when the base member is coupled to the meter.

7. The device of claim 1, wherein the electronics assembly further includes an illuminator coupled to the image sensor for illuminating the display area of the meter.

8. The device of claim 7, wherein the electronics assembly further includes an illumination sensor coupled to the illuminator, and wherein an illumination intensity output of the illuminator is adjusted based on output of the illumination sensor.

9. The device of claim 1, wherein the electronics assembly further includes a tampering sensor arrangement including at least one of a magnetic sensor and an accelerometer.

10. The device of claim 1, wherein the display area of the meter includes at least one of a first region displaying a numerical meter reading, and a second region displaying an identifier of the meter.

11. The device of claim 1, wherein the fastening member includes:

an annular body defined in part by an inner sidewall, an outer sidewall, and the hollow section, and wherein the mechanism includes at least one resiliently biased detent extending away from the annular body for engaging the portion of the meter.

12. The device of claim 1, wherein the base member further includes a two-sided central section that separates the base member into an upper portion and a lower portion, the lower portion being in communication with the display cover of the meter, and wherein the central section includes a window extending from one side of the central section to the other side of the central section, and wherein the window is aligned with the display area of the meter to provide a user of the device with an unobstructed view of the display area.

13. 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 first 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 hub unit including;

a first hub unit communications module configured to receive the transmitted image data from the remote unit communications module over the first communications channel, and

a hub unit processing unit including at least one processor coupled to a storage medium configured to;

analyze the received image data to extract information from the image data, the information including at least an identifier of the meter and a meter reading of the meter for each of the images captured by the image sensor.

14. The system of claim 13, wherein the hub unit further comprises a second hub unit communications module, and wherein the system further comprises:

a remote server for receiving data from the hub unit, wherein the second hub unit communications module is configured to transmit data to the remote server over a second communications channel.

15. The system of claim 14, wherein the hub unit processing unit is further configured to:

actuate the second hub unit communications module to transmit the extracted information to the remote server, and wherein the remote server is configured to compare the identifier of each received image with a stored identifier associating the remote unit with the meter.

16. The system of claim 14, wherein the second hub unit communications module is further configured to receive data from the remote server over the second communications channel, the received data including a programmable transmit and receive schedule for the remote unit communications module, and wherein the first hub unit communications module is further configured to transmit the programmable transmit and receive schedule to the remote unit communications module, and wherein the hub processing unit is further configured to:

actuate the remote unit communications module to operate according to the programmable transmit and receive schedule.

17. The system of claim 14, wherein the second hub unit communications module is further configured to receive a request from the remote server over the second communications channel, and wherein the hub processing unit is further configured to:
