METHOD OF PREVENTING FAILURE OF READING WIRELESS TAGS, AND WIRELESS TAG DATA MANAGEMENT SYSTEM
First Claim
1. A method of preventing failure of reading wireless tags, for use in a wireless tag data management system comprising a wireless tag reader/writer for reading and writing tag data items from and in wireless tags by performing radio communication with the wireless tags, and a host computer connected to the wireless tag reader/writer, the method comprising:
- a grouping step of dividing tag IDs of the plurality of wireless tags into groups;
a tag-data storing step of sequentially storing tag data items in storage areas provided for the wireless tags, respectively, each tag data item including a tag ID and related-tag data constituted by the tag IDs of other wireless tags belonging to the same group as the wireless tag;
a tag-data reading step of reading the tag data items stored in the tag-data storing step, by using the wireless tag reader/writer;
a determining step of generating a list of read tag IDs and a list of related tag IDs, from the tag IDs included in the tag data items read in the tag-data reading step and the related-tag data, and then determining whether the read tags coincide with the related tags; and
a reading-error outputting step of outputting reading-error data to a display unit of a host computer when tag IDs are determined to exist in the list of related tag IDs but not in the list of read tag Ids, in the determining step.

Abstract
A method includes a step of dividing tag IDs of plural wireless tags into groups; a step of sequentially storing tag data items in storage areas provided for the wireless tags, each tag data item including a tag ID and related-tag data constituted by the tag IDs of other wireless tags belonging to the same group as the wireless tag; a step of reading the stored tag data items; a step of generating a list of read tag IDs and a list of related tag IDs, from the tag IDs included in the tag data items read in the tag-data reading step and the related-tag data, and then determining whether the read tags coincide with the related tags; and a step of outputting reading-error data when tag IDs are determined to exist in the list of related tag IDs but not in the list of read tag IDs.

5. A wireless tag data management system comprising:
-
wireless tags, each of which has at least a user-data area in which a user is able to write data, a tag ID inherent to the wireless tag and related-tag data constituted by the tag IDs of other wireless tags defined as belonging to the same group are stored; a wireless tag reader/writer configured to read and write tag data items from and in the wireless tags by performing radio communication with the wireless tags; a determining unit connected to the wireless tag reader/writer and configured to analyze the tag data items read by the wireless tag reader/writer, thereby determining whether the wireless tag reader/writer has failed to read any wireless tag; and a display unit configured to display a reading error when the determining unit determines that the wireless tag reader/writer has failed to read any wireless tag. - View Dependent Claims (6, 7, 8, 9, 10)
