Article management system, article management method, and non-transitory computer readable medium storing article management program
First Claim
1. An article management system comprising:
- a reader waveguide formed as an open transmission line terminated with matching impedance;
a plurality of RFID tags fixed in an article allocable area above the reader waveguide and electromagnetically coupled to the reader waveguide;
a tag position table storage unit implemented by at least one storage device that stores a tag position table associating tag information of the plurality of RFID tags and fixed positions of the plurality of RFID tags;
an article position table storage unit implemented by the at least one storage device that stores an article position table associating identification information of articles and assigned positions of the articles assigned to place the articles in the allocable area;
an article management table storage unit implemented by the at least one storage device that stores an article management table associating the identification information of the articles and the tag information of the plurality of RFID tags based on the tag position table and the article position table;
a tag reading unit that reads the plurality of RFID tags by electromagnetic coupling through the reader waveguide; and
an article presence/absence determination unit implemented by a processor that determines presence or absence of an article corresponding to the plurality of RFID tags based on results of reading the plurality of RFID tags by referring to the article management table.

Abstract
An article management system includes RFID tags (102) fixed above a reader waveguide (101), a tag position table storage unit (106) that stores tag information and fixed positions of the RFID tags (102) in association with each other, an article position table storage unit (105) that stores identification information and an assigned position of an article (108) in association with each other, an article management table storage unit (107) that stores the identification information of the article (108) and the tag information of the RFID tags (102) in association with each other, a tag reading unit (103) that reads the RFID tags (102) by electromagnetic coupling through the reader waveguide (101), and an article presence/absence determination unit that determines presence or absence of placement of the article (108) corresponding to the RFID tags (102) based on results of reading the RFID tags (102).
