INDUSTRIAL VEHICLE FOR IDENTIFYING MALFUNCTIONING SEQUENCED TAG AND TAG LAYOUT FOR USE THEREWITH

An industrial vehicle comprises industrial vehicle hardware, a tag reader (30), a reader module (35), a user interface, and a vehicle controller (40). The industrial vehicle hardware comprises storage and retrieval hardware (20), a vehicle drive mechanism (25) and a travel distance sensor (43). The tag reader (30) and the reader module (35) cooperate to identify individual tags of a tag layout (50, 50'). The individual tags of the tag layout (50, 50') comprise a plurality of sequenced tags (130). The plurality of sequenced tags (130) are sequenced along an aisle path (70) in accordance with a sequence list that is accessible to the reader module (35). The reader module (35) comprises a reader memory (205) coupled to a reader processor (208). Each individual tag of the tag layout (50) corresponds to a memory location (200) in the reader memory (205). The memory locations (200) in the reader memory (205) are stored in a known order corresponding to the sequence of the sequenced tags. The travel distance sensor (43) measures a tag distance from an identified sequence tag. The reader module (35) advances or retards the reader memory (35) one memory location (200) to a new memory location (200) from the memory location (200) corresponding to the identified sequence tag when an error distance measurement threshold is exceeded by the tag distance measurement, wherein the advancement or retardation from the memory location (200) corresponding to the identified sequence tag is dependent on a travel direction of the industrial vehicle (10) along the aisle path (70), and correlates vehicle functionality corresponding to the new memory location (200) with a current location of the industrial vehicle (10). The vehicle controller (10) controls operational functions of the industrial vehicle hardware in response to (i) the correlation of vehicle functionality with the new memory location (200), (ii) the correlation of vehicle functionality with an identified tag in the tag layout, tag-dependent positional data, or both, (iii) user input at the user interface of the industrial vehicle, or (iv) combinations thereof.
