Patent ID: 7378980

Claim:
A method for locating building automation devices, the method comprising: (a) determining distances from a reference source to a plurality of building automation devices configured for directional wireless communication, the distances being determined using directional wireless communication between each of the plurality of building automation devices and the reference source, the reference source being a building automation device, controller, processor, or other object located at a known coordinate location within a reference system and each of the plurality of building automation devices being located at an unknown coordinate location; (b) determining projection angles from the reference source to each of the plurality of building automation devices, the projection angles being determined using directional wireless communication between each of the plurality of building automation devices and the reference source; (c) calculating a coordinate location for each of the plurality of building automation devices having an unknown coordinate location using the (1) the distances from the reference source to a corresponding one of the plurality of building automation devices determined via directional wireless communication and (2) the projection angle from the reference source to the corresponding one of the plurality of building automation devices determined via directional wireless communication; (d) storing the coordinate location calculated for each of the plurality of building automation devices using the distances and the projection angles determined via directional wireless communication in an electronic storage medium; and (e) subsequently determining an actual position of one of the plurality of building automation devices based upon the corresponding stored coordinate location.
