Automated system for producing location-based inventories
First Claim
1. System for producing location-based inventories of objects each furnished with an RFID transponder (24) designed to interact with an RFID reader/interrogator (30) and placed at different locations of a warehousing structure (10) including a plurality of rows (16A-16C) supported by vertical uprights (18A-18D),wherein each of the vertical uprights is furnished at each of the rows with an RFID location transponder (26) and wherein each of the beginning uprights (18A) and end uprights (18D) of a row is also furnished with a lock on marker (28B) designed to device (28A) associated with the RFID read/interrogator,wherein the system comprises:
- processing means (30;
32) for producing a location-based inventory of the objects present on the said warehousing structure according to information received from the RFID transponders and the RFID location transponders and for providing a location of the RFID reader/interrogator relative to the warehousing structure, reading of said received information being disabled by said processor means for the time necessary for the RFID reader/interrogator to pass from one row to another, the RFID reader/interrogator conducting multiple reads on each of the RFID transponders and the RFID location transponders; and
a first filtration means for filtering data received and read from the RFID transponders and the RFID locator transponders by deleting spurious reads and by retaining only majority reads.

Abstract
A system for producing a location-based inventory of objects each furnished with an RFID transponder (24) designed to interact with an RFID reader/interrogator (30) and placed at different locations of a warehousing structure (10) including a plurality of rows (16A-16C) supported by vertical uprights (18A-18D). Each of the uprights of this warehousing structure is furnished at each of the rows with an RFID location transponder (26) and a processor (30; 32) to produce a location-based inventory of the objects present on the warehousing structure according to the information received from the transponders.

7. Method for producing a location-based inventory of objects each furnished with an RFID transponder designed to interact with an RFID reader/interrogator and placed at different locations in a warehousing structure including a plurality of rows supported by vertical uprights including respective beginning and end uprights each comprising at each of the rows an RFID location transponder, the said method comprising the steps of:
-
providing each of the beginning uprights and end uprights of a row with a lock-on marker configured to interact with a lock-on device associated with the RFID reader/interrogator; moving said RFID reader/interrogator in front of each of the rows of the said warehousing structure in turn; during this movement, interrogating and reading data received from the RFID transponders of the said objects and data received from each of the RFID location transponders a multitude of times, from this reading determining the location of each of the said objects in the said warehousing structure and the location of the RFID reader/interrogator with respect to the warehouse structure, reading of said data received from said RFID transponders and said RFID location transponders being disabled by processing means for the time necessary for the RFID reader/interrogator to pass from one row to another, and to determine the location of each object, carrying out a first filtration on the data received and read from the RFID transponders and the RFID location transponders by deleting spurious reads and by retaining only majority reads. - View Dependent Claims (8, 9, 10)
