Abstract

A system and methods for automatically commissioning electrical fixtures using sound are disclosed. Electrical fixtures (140-149) detect sounds produced by a sound generator moved along a path (300) through installed fixtures according to a building plan (100). Each electrical fixture may be associated with a mapped fixture location in the building plan by correlating the detected sound with the location of the sound generator along the path.

Claims

1. A method for automatically commissioning a first fixture having a first microphone and a second fixture having a second microphone according to a building plan having a first mapped location and a second mapped location, the method comprising the steps of:

generating a first sound at a first location;

detecting said first sound by said first microphone and by said second microphone;

generating a second sound at a second location;

detecting said second sound by said first microphone and by said second microphone; and

associating said first fixture with said first mapped location.

2. The method of claim 1, further comprising the step of associating said second fixture with said second mapped location.

3. The method of claim 1, further comprising the steps of:

recording a first time when said first microphone detects said first sound;

recording a second time when said second microphone detects said first sound;

recording a third time when said first microphone detects said second sound; and

recording a fourth time when said second microphone detects said second sound;

wherein said associating said first fixture with said first mapped location is based in part upon said first, second, third and fourth time.

4. The method of claim 3, further comprising the steps of:

determining a first distance between said first microphone and said first location, based upon said first time;

determining a second distance between said second microphone and said first location, based upon said second time;

determining a third distance between said first microphone and said second location, based upon said third time; and

determining a fourth distance between said second microphone and said second location, based upon said fourth time.

5. The method of claim 4, wherein said first location and said second location are along an arbitrary path.

6. The method of claim 4, further comprising the step of determining a fifth distance between said first microphone and said second microphone based in part upon said first, second, third and fourth time.

7. The method of claim 1, wherein said first location and said second location are substantially along a predetermined path.

8. The method of claim 1, wherein said first sound is a first footstep and said second sound is a second footstep.

9. The method of claim 1, wherein said first fixture comprises a first luminaire and said second fixture comprises a second luminaire.

10. The method of claim 8, further comprising the step of acknowledging said associating said first fixture with said first mapped location with a visible response by said first luminaire.

11. The method of claim 3, wherein said first fixture further comprises a first clock, and said second fixture further comprises a second clock.

12. The method of claim 11, further comprising the step of synchronizing said first clock with said second clock.

13. The method of claim 1, further comprising the steps of:

generating a third sound, wherein said third sound is audibly distinct from said first sound and said second sound; and

detecting said third sound with said first microphone;

wherein said first sound is substantially audibly indistinguishable from said second sound.

14. The method of claim 13, further comprising the step of:

in response to said detecting said third sound, dis-associating said first fixture with said first mapped location and/or ending said automatic commissioning method.

15. A method for automatically commissioning a first fixture having a first microphone and a second fixture 4444 having a second microphone according to a building plan having a first mapped location and a second mapped location, the method comprising the steps of:

generating a substantially fixed frequency tone with a tone generator at a first location detecting said tone by said first microphone and by said second microphone;

moving said tone generator to a second location;

detecting a Doppler shift of said tone by said first microphone; and

associating said first fixture with said first mapped location.

16. A system for automatically commissioning fixtures according to a building plan having a first mapped location and a second mapped location, comprising:

a lighting control system in communication with a data network;

a first fixture comprising a first microphone in communication with said data network,

wherein said first fixture is configured to transmit detection notification of each of a plurality of sounds to said lighting control system; and

a second fixture comprising a second microphone in communication with said data network,

wherein said second fixture is configured to transmit detection notification of each of said plurality of sounds to said lighting control system;

wherein said lighting control system is configured to associate said first fixture with said first mapped location and said second fixture with said second mapped location based upon receiving said detection of said plurality of sounds from said first fixture and said second fixture.

17. The system of claim 16, wherein said data network is a wired network configured for communicating data over power lines providing power to said first fixture, said second fixture, and said lighting control system.

18. The system of claim 16, wherein said data network is a wireless network.

19. The system of claim 16, wherein said plurality of sounds are footsteps.

20. Computer readable media configured to execute a method for automatically commissioning a first fixture having a first microphone and a second fixture having a second microphone according to a building plan having a first mapped location and a second mapped location comprising the steps of:

receiving notification of detection by said first fixture of each of a plurality of sounds;

receiving notification of detection by said second fixture of each of said plurality of sounds; and

associating said first fixture with said first mapped location and said second fixture with said second location based upon receiving said detection of said plurality of sounds from said first fixture and said second fixture.
