Apparatus and method for reading gauges and other visual indicators in a process control system or other data collection system
First Claim
1. A portable apparatus comprising:
- an attachment interface configured to removably mount the apparatus to multiple visual indicators including a plurality of different gauges of different sizes or different structures;
a camera configured to capture images of the multiple visual indicators, each visual indicator having an associated unique identifier and comprising a display configured to present a gauge reading; and
a recording device configured to;
perform optical character recognition on the captured images received from the camera to identify at least part of the gauge readings presented on the displays of the visual indicators;
identify timestamps of the captured images received from the camera;
identify the unique identifiers for the visual indicators using an identification reader separate from the camera;
associate each of the identified gauge readings and the identified timestamps with one of the visual indicators based on the identification of the unique identifiers; and
at least one of store and transmit information including the identified gauge readings, the identified timestamps, and the identified unique identifiers of the visual indicators.

Abstract
A portable apparatus includes a camera configured to capture images of multiple visual indicators. Each visual indicator, such as a gauge or meter, includes a display configured to present a reading. The portable apparatus also includes a recording device configured to store and/or transmit information associated with the captured images of the visual indicators. The camera and/or the recording device could be configured to identify, using the images, the readings presented on the displays of the visual indicators, and the information associated with the captured images could include the readings. Also, the camera could be configured to be mounted on each visual indicator in order to capture one or more images of the visual indicator'"'"'s display and to be removed from the visual indicator after the one or more images are captured.

11. A method comprising:
-
removably coupling a reading device to multiple visual indicators including a plurality of different gauges of different sizes or different structures, each visual indicator having an associated unique identifier; capturing an image of a first display of a first of the visual indicators using the reading device, the first display presenting a first gauge reading; capturing an image of a second display of a second of the visual indicators using the reading device, the second display presenting a second gauge reading; performing optical character recognition on the captured images to identify at least part of the first and second gauge readings presented on the first and second displays of the first and second visual indicators, respectively; identifying timestamps of the captured images; identifying the unique identifiers for the first and second visual indicators, respectively, using an identification reader separate from a camera used to capture the images; associating the first gauge reading and one of the identified timestamps with the first visual indicator based on the identification of the unique identifier of the first visual indicator and associating the second gauge reading and another one of the identified timestamps with the second visual indicator based on the identification of the unique identifier of the second visual indicator; and at least one of storing and transmitting information including the first and second identified gauge readings, the identified timestamps, and the identified unique identifiers. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system comprising:
-
multiple visual indicators, each visual indicator having an associated unique identifier and comprising a display configured to present a gauge reading; and a reading device configured to; removably mount to the multiple visual indicators including a plurality of different gauges of different sizes or different structures; capture images of two or more of the visual indicators; perform optical character recognition on the captured images to identify at least part of the gauge readings presented on the displays of the visual indicators; identify timestamps of the captured images; identify the unique identifiers for the visual indicators using an identification reader separate from a camera used to capture the images; associate each gauge reading and each of the identified timestamps with one of the visual indicators based on the identification of the unique identifiers; and at least one of store and transmit information including the identified gauge readings, the identified timestamps, and the identified unique identifiers. - View Dependent Claims (19, 20)
