Abstract

An infrastructure monitoring system and method include multiple communications devices. At least one communications device is coupled to an element of the infrastructure.

Claims

1. A nozzle cap assembly comprising:

a nozzle cap; and

a communications device coupled to the nozzle cap, wherein the communications device is a component of an infrastructure monitoring system.

2. The nozzle cap assembly of claim 1, wherein the nozzle cap defines an interior cavity and wherein the communications device is located inside the interior cavity.

3. The nozzle cap assembly of claim 1, wherein the communications device is insulated from water.

4. The nozzle cap assembly of claim 1, wherein the nozzle cap is comprised of a composite material.

5. The nozzle cap assembly of claim 4, wherein the composite material has a color that fades at a rate that is the same as a rate of fading of a color of paint.

6. The nozzle cap assembly of claim 4, wherein the composite material does not interfere with wireless signals.

7. The nozzle cap assembly of claim 1, wherein the nozzle cap includes an enclosure, a cover to seal the enclosure, and an antenna cover.

8. The nozzle cap assembly of claim 7, wherein the cover creates a water tight seal on the enclosure.

9. The nozzle cap assembly of claim 8, wherein the communications device is positioned within the enclosure and the cover.

10. The nozzle cap assembly of claim 8, wherein the cover and enclosure are water tight up to 400 psi.

11. The nozzle cap assembly of claim 7, wherein the nozzle cap includes internal threading and the enclosure includes external threading, and wherein the threading of the enclosure connects the enclosure to the threading of the nozzle cap.

12. The nozzle cap assembly of claim 11, wherein the connection between the enclosure and the nozzle cap is water tight up to 400 psi.

13. The nozzle cap assembly of claim 1, wherein the nozzle cap is coupled to a fire hydrant.

14. A fire hydrant comprising:

a nozzle cap; and

a communications device coupled to the nozzle cap, wherein the communications device is a component of an infrastructure monitoring system.

15. The fire hydrant of claim 14, wherein the nozzle cap defines an interior cavity and wherein the communications device is located inside the interior cavity.

16. The fire hydrant of claim 14, wherein the communications device is insulated from water.

17. The fire hydrant of claim 14, wherein the nozzle cap is comprised of a composite material.

18. The fire hydrant of claim 17, wherein the composite material has a color that fades at a rate that is the same as a rate of fading of a color of paint.

19. The fire hydrant of claim 17, wherein the composite material does not interfere with wireless signals.

20. The fire hydrant of claim 14, wherein the nozzle cap includes an enclosure, a cover to seal the enclosure, and an antenna cover.

21. The fire hydrant of claim 20, wherein the cover creates a water tight seal on the enclosure.

22. The fire hydrant of claim 21, wherein the communications device is positioned within the enclosure and the cover.

23. The fire hydrant of claim 21, wherein the cover and enclosure are water tight up to 400 psi.

24. The fire hydrant of claim 20, wherein the nozzle cap includes internal threading and the enclosure includes external threading, and wherein the threading of the enclosure connects the enclosure to the threading of the nozzle cap.

25. The fire hydrant of claim 24, wherein the connection between the enclosure and the nozzle cap is water tight up to 400 psi.
