DIAGNOSTIC TAG FOR AN INDUSTRIAL VEHICLE TAG READER
First Claim
1. An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein:
- the diagnostic tag is coupled to the industrial truck within a read range of the tag reader;
the reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout; and
the reader modulediscriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout,correlates an identified individual tag of the tag layout with tag data,correlates an identified diagnostic tag with operation of the tag reader, andgenerates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

Abstract
An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

9. A method for identifying a fault in a RFID system comprising a tag reader, a diagnostic tag, and a reader module, the method comprising:
-
initializing the tag reader; identifying the diagnostic tag and individual tags of a tag layout through the cooperation of the tag reader and reader module; enabling the diagnostic tag; modulating power to the diagnostic tag such that the diagnostic tag does not interfere with the identification of the individual tags of the tag layout; generating a missing tag signal if the diagnostic tag is not identified while it is enabled or the operation of the tag reader is not within specified operating parameters; and disabling the diagnostic tag if an individual tag of the tag layout is identified. - View Dependent Claims (10, 11)
