Abstract

Mapping the physical location of each sensor of a network of wireless sensors in a configured environment, each sensor being in communication with a server and its database, is achieved by attaching RFID tags to objects in the environment which contain both object-relevant information and the MAC address of sensors proximate to those objects. The locations of the tags on the objects are proxies for the locations of the sensors identified on those tags. By reading the tags and up-loading the read tag information to the database, the association of the sensor and the object is known to the server and can be matched with the configuration of the environment to infer the location of each wireless sensor.

Claims

1. A system, comprising:

a server configured for receiving and processing digital information and wireless signals;

a database in communication with said server and configured to store and retrieve said digital information received by said server;

a plurality of tags deployed in an environment, a tag of said plurality of tags storing position-related digital information, said tag being a radio frequency identification tags;

a plurality of wireless sensors deployed within said environment, said wireless sensors being in wireless communication with said server, a wireless sensor of said plurality of wireless sensors having an identity which is a media access control address, said identity being stored on said tag in association with said position-related digital information, said wireless sensor being configured to sense a change and to emit a signal upon sensing said change, said server receiving and responding to said signal; and

a machine configured for reading and outputting to said server said position-related digital information and said identity of said wireless sensor on said tag, wherein said server stores said position-related digital information and said identity in said database so that said server associates said wireless sensor with said position-related digital information of said tag and responds to said wireless sensor associated with said tag.

2. The system of claim 1, wherein said environment includes a configuration of objects, said configuration being stored on said database and wherein said tag is deployed in said environment in association with an object of said objects.

3. The system of claim 2, wherein said tag is attached to a first surface in said environment and said wireless sensor is attached to a second surface in said environment.

4. The system of claim 3, wherein said first and second surfaces are on said object.

5. The system of claim 3, wherein said first surface is in spaced relationship with said second surface.

6. The system of claim 3, wherein said first and second surfaces are on a first and a second object of said objects, respectively, and said first and said second objects are in spaced relationship with each other.

7. The system of claim 1, wherein said environment is the interior of a vehicle.

8. The system of claim 7, wherein said vehicle is a passenger aircraft.

9. The system of claim 8, wherein said tags are attached to seats in said passenger aircraft.

10. The system of claim 8, wherein said sensors are attached to seats in said passenger aircraft.

11. The system of claim 1, wherein said tag stores more than one identity.

12. The system of claim 11, wherein said wherein said more than one identity is stored in a preselected arrangement on said tag.

13. The system of claim 12, wherein said more than one identity corresponds to more than one adjacent seat in a row of seats.

14. A method, comprising the steps of:

deploying a plurality of wireless sensors in an environment, a sensor of said plurality of sensors configured to sense a change in said environment and emit a signal related to said change, said sensor having an identity which is a media access control address;

deploying a plurality of machine-readable tags in said environment, a tag of said plurality of tags including location-related digital information and said identity of said sensor so that said identity is associated with said location-related digital information, said tag being a radio frequency identification tag;

reading said tag to obtain said location-related digital information of said tag and said identity of said sensor; and

outputting location-related digital information and said identity read from said tag to a configuration database, wherein said database stores said location-related digital information associated with said identity in said database.

15. The method of claim 14, further comprising the step of configuring an environment containing objects and wireless sensors before deploying said plurality of sensors and said plurality of machine-readable tags to said environment.

16. The method of claim 15, further comprising the step of attaching said machine-readable tags to objects in said environment.

17. A method, comprising the steps of:

providing a configuration for a plurality of objects within an environment;

deploying a plurality of objects into said environment according to said configuration, an object of said plurality of objects carrying a machine-readable radio frequency identification tag having radio frequency identification number;

deploying a plurality of wireless sensors into said environment, a wireless sensor of said plurality of wireless sensors having a media access control address, said wireless sensor being operable to sense a change in said environment proximate to said wireless sensor and emit a signal related to said change;

applying said media access control address to said radio frequency identification tag whereby said media access control address and said radio frequency identification number are associated so as to be readable together;

reading said media access control address and said radio frequency identification number from said radio frequency identification tag; and

transmitting said media access control address and said radio frequency identification number to a processor.

18. The method of claim 17, further comprising the step of storing said media access control address and said radio frequency identification number in a database.

19. The method of claim 17, wherein said environment is the interior of a vehicle.

20. The method of claim 19, wherein said vehicle is a passenger aircraft.

21. The method of claim 20, wherein said radio frequency identification tag is attached to seats in said passenger aircraft.
