Symbol reading system having predictive diagnostics

摘要

A retail information network includes one or more POS scanning and checkout systems, each including (i) a bar code symbol reading subsystem, and (ii) a cash register computer subsystem interfaced with the bar code symbol reading subsystem and a network infrastructure, and each having access to product and price data maintained in a product/price database. The bar code symbol reading subsystem includes a local predictive error event (PEE) data store for logging and storing predictive error events (PEEs) detected within the bar code symbol reading system, wherein said PEEs are subsequently sent to POS information servers used to create predictive error alerts (PEAs) and corresponding instructions to maintain and/or repair certain aspects of the bar code symbol reading system.

1. A system, comprising:
a symbol reading system communicatively connected to a product/price database for reading symbols, the symbol reading system comprising:
a local predictive error event (PEE) database for generating and storing PEE records of predictive error events (PEEs) detected within the symbol reading system; anda processor; and a remote PEE database communicatively connected to the symbol reading system for storing PEE records generated by the symbol reading system; wherein the symbol reading system's processor is configured for:
determining if the number of detected PEEs exceeds a threshold; andif the number of detected PEEs exceeds the threshold, transmitting the generated PEE records to the remote PEE database.
