Abstract

Remote monitoring and inspection of measurement devices, emergency equipment, parking spaces, and other items is accomplished by using an image sensor (e.g., a CMOS sensor) to capture an image containing information about the monitored item. A signal containing information about the image (e.g., data representing the captured image or data indicating the state of the captured image) is transmitted to a remote central station.

Claims

1. Apparatus for detection of presence of an obstruction blocking access to an emergency exit, the apparatus comprising:

an image sensor positioned to face an access area to the emergency exit and configured to capture an image of the access area;

an image recognition module configured to;

recognize at least whether the access area is obstructed; and

generate a first signal indicative of an obstructed state when the access area is recognized as obstructed; and

communications circuitry configured to transmit to a remote central station a second signal including the image of the access area captured by the image sensor.

2. The apparatus of claim 1 wherein the image sensor is configured to periodically capture a new image of the access area.

3. The apparatus of claim 1 wherein the emergency exit includes an emergency stairway.

4. The apparatus of claim 1 wherein the image sensor is configured to capture the image of the access area in response to a change in a state of an item of emergency equipment.

5. The apparatus of claim 4 wherein the change in the state of the item of emergency equipment includes a removal of the emergency equipment from an installed position.

6. The apparatus of claim 4 wherein the access area includes a fire alarm pull station.

7. The apparatus of claim 6 wherein the change in the state of the emergency equipment comprises an activation of the fire alarm pull station.

8. The apparatus of claim 1 wherein the access area includes a portable defibrillator.

9. The apparatus of claim 1 further comprising a network linking the communication circuitry and the remote central station.

10. The apparatus of claim 9 wherein the network includes a wireless mesh network.

11. The apparatus of claim 1 wherein the image sensor includes a CMOS sensor.

12. The apparatus of claim 1 further comprising a second image sensor positioned to face a display of an item of emergency equipment in the access area and configured to capture a second image of the display of the item of emergency equipment, wherein the communications circuitry is further configured to transmit to a remote central station a third signal including information about the display.

13. The apparatus of claim 12 wherein the image recognition module is configured to recognize one of a plurality of predetermined states of the item of emergency equipment from the second image.

14. The apparatus of claim 13 wherein the image recognition module is configured to recognized one of the plurality of predetermined states prior to transmission of the third signal to the remote central station.

15. The apparatus of claim 12 wherein the item of emergency equipment includes a pressurized tank and the display includes a pressure gauge on pressurized tank.

16. The apparatus of claim 12 wherein the second image sensor is configured to periodically capture an image of the display.

17. The apparatus of claim 1 further comprising a second image sensor positioned to face an installed location of an item of emergency equipment and configured to capture a second image of the installed location, wherein the communications circuitry is further configured to transmit to the remote central station a third signal including information about the second image.

18. The apparatus of claim 1 wherein the communication circuitry is configured to transmit a wireless signal to the remote central station.

19. The apparatus of claim 1 wherein the network includes a wireless mesh network.

20. The apparatus of claim 16 wherein the network includes an IEEE 802.15.4-compliant network.
