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;
recording a first time when said first microphone detects said first sound, and a second time when said second microphone detects said first sound;
generating a second sound at a second location;
detecting said second sound by said first microphone and by said second microphone; and
recording a third time when said first microphone detects said second sound, a fourth time when said second microphone detects said second sound;
associating said first fixture with said first mapped location, wherein said associating is based in part upon said first, second, third, and fourth time.

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.

14. 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 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.

15. 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, 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. - View Dependent Claims (16, 17)
