SENSOR NETWORK FOR MANAGING THE LOCATION OF MATERIALS ON A CONSTRUCTION SITE
First Claim
1. A sensor network for managing the location of materials on a construction site, comprising:
- a plurality of radio frequency sensors having unique identifiers;
attachments for attaching the radio frequency sensors to selected items;
a radio frequency sensor reader network comprising two or more radio frequency sensor readers, at least two radio frequency sensor readers sensing the unique identifier of each of the radio frequency sensors and the distance from the radio frequency sensor reader to each radio frequency sensor;
a processor connected to the radio frequency sensor reader network for determining the location of at least one radio frequency sensor based on the unique identifier and distance sensed by each radio frequency sensor reader;
a selection device for selecting a radio frequency sensor based on a user input;
at least one image capture device having a movable field of view, the field of view moving in response to the user input into the selection device and the corresponding location calculated by the processor to include the selected radio frequency sensor; and
a display device connected to the image capture device for displaying the field of view of the image capture device.

Abstract
A sensor network for managing the location of materials on a construction site includes RF sensors having unique identifiers attached to selected items. A radio frequency sensor reader network with two or more RF sensor readers sense the unique identifier of each of the radio frequency sensors and their distance from each radio frequency sensor. A processor connected to the radio frequency sensor reader network determines the location of the radio frequency sensors based on the unique identifier and distance sensed by each radio frequency sensor reader. A selection device for selects a RF sensor based on a user input, and an image capture device moves in response to the user input to display the selected radio frequency sensor on a display device.

10. A method of managing the location of materials on a construction site, the method comprising the steps of:
-
providing a radio frequency network comprising two or more radio frequency sensors; attaching a radio frequency tag having a unique identifier to each item on the construction site to be managed; sensing the unique identifier of at least one radio frequency tag by at least two radio frequency sensors and the distance of the at least one radio frequency tag to each of the at least two radio frequency sensors; calculating a location for each sensed radio frequency tag based on the unique identifier and distance information sensed by the radio frequency sensors; selecting a unique identifier processed by the processor; moving the field of view of an image capture device having a movable field of view to the selected radio frequency tag; and displaying the field of view of the image capture device on a display device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
