Abstract

A wireless sensing system and method for wireless sensor interrogation are disclosed. The wireless sensing system includes a plurality of radio frequency sensors distributed within a predefined area, a wiring system with conductors distributed in proximity to the plurality of sensors for providing at least one of electrical power and ground distribution, and a forward communication link with an energizer air link coupled to the wiring system. The method for wireless sensor interrogation includes providing a plurality of radio frequency sensors distributed within a predefined area, providing a forward communication link including an energizer coupled to a wiring system with conductors in proximity to the plurality of sensors for providing at least one of electrical power and ground distribution, transmitting radio frequency signals through the wiring system and air linking transmitted radio frequency signals to the plurality of radio frequency sensors through the conductors.

Claims (30)

1. Wireless sensing system comprising:

a plurality of wireless radio frequency sensors distributed within a predefined area;

a wiring system including conductors distributed in proximity to said plurality of wireless radio frequency sensors within said predefined area, said conductors providing one of electrical power and ground distribution to a device other than any of said wireless radio frequency sensors; and

a forward communication link including an energizer air link coupled to said wiring system, the energizer providing radio frequency signals intended for the plurality of wireless radio frequency sensors to the wiring system, the wiring system air linking said radio frequency signals to the plurality of wireless radio frequency sensors.

2. The wireless sensing system as claimed in claim 1 wherein the air link is near field.

3. The wireless sensing system as claimed in claim 1 further comprising: a reverse communication link including a reader receiving radio frequency signals from the plurality of wireless radio frequency sensors.

4. The wireless sensing system as claimed in claim 1 wherein said wiring system comprises a vehicular wiring harness.

5. The wireless sensing system as claimed in claim 1 wherein said wiring system further comprises a wiring distribution center whereat said conductors are consolidated and wherein said energizer is air link coupled to said wiring system at said wiring distribution center.

6. The wireless sensing system as claimed in claim 5 wherein the air link is near field.

7. The wireless sensing system as claimed in claim 3 wherein the reader receives radio frequency signals from the plurality of wireless radio frequency sensors exclusively via air links.

8. The wireless sensing system as claimed in claim 3 wherein the reader is air link coupled to said wiring system, the reader receiving radio frequency signals from the plurality of wireless radio frequency sensors via said wiring system.

9. The wireless sensing system as claimed in claim 8 wherein the air links are near field.

10. The wireless sensing system as claimed in claim 3 wherein said wiring system further comprises a wiring distribution center whereat said conductors are consolidated and wherein said energizer is air link coupled to said wiring system at said wiring distribution center.

11. The wireless sensing system as claimed in claim 10 wherein the air link is near field.

12. The wireless sensing system as claimed in claim 10 wherein the reader is air link coupled to said wiring system at said wiring distribution center, the reader receiving radio frequency signals from the plurality of wireless radio frequency sensors via said wiring system.

13. The wireless sensing system as claimed in claim 12 wherein the air links are near field.

14. The wireless sensing system as claimed in claim 8 wherein the energizer and reader comprise a transceiver.

15. The wireless sensing system as claimed in claim 12 wherein the energizer and reader comprise a transceiver.

16. Method for wireless sensor interrogation, comprising:

providing a plurality of wireless radio frequency sensors distributed within a predefined area;

providing a forward communication link including an energizer coupled to a wiring system including conductors in proximity to said plurality of wireless radio frequency sensors distributed within said predefined area, said conductors providing one of electrical power and ground distribution to a device other than any of said wireless radio frequency sensors;

transmitting radio frequency signals through the wiring system; and

air linking transmitted radio frequency signals to the plurality of wireless radio frequency sensors through said conductors.

17. The method for wireless sensor interrogation as claimed in claim 16 further comprising:

providing a reverse communication link including a reader receiving radio frequency signals from the plurality of wireless radio frequency sensors.

18. The method for wireless sensor interrogation as claimed in claim 17 wherein:

providing a reverse communication link including a reader receiving radio frequency signals from the plurality of wireless radio frequency sensors includes receiving radio frequency signals from the plurality of wireless radio frequency sensors exclusively via air links.

19. The method for wireless sensor interrogation as claimed in claim 17 wherein:

providing a reverse communication link including a reader receiving radio frequency signals from the plurality of wireless radio frequency sensors includes air linking the reader to said wiring system; and

receiving radio frequency signals from the plurality of wireless radio frequency sensors exclusively via air links includes through conductors proximate the plurality of wireless radio frequency sensors.
