EIR Terminal Interface Node for Fleet Software Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing large fleets of portable encoded information reading terminals (EIR terminals) for software upgrades and configuration updates is inefficient due to the substantial planning and effort required for communicating and interfacing with numerous mobile terminals.
Innovation Solution
A network-accessible EIR terminal interface node that manages terminal reprogramming by processing status messages, building reprogramming messages, and transmitting updates, utilizing a terminal status database, reprogramming database, and resource network communication protocols like SOAP and ODBC, with caching to reduce data traffic and scheduling updates during docking periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual management methods are used for large fleets of mobile EIR terminals, then flexibility in managing different terminal subsets is improved, but the substantial planning and effort required worsens operational efficiency
Solution Approach 1:
The patent introduces an interface node as an intermediary between the resource network and the fleet of EIR terminals. This interface node automatically manages terminal subsets, software upgrades, and configuration updates, eliminating the need for manual planning and effort while maintaining flexibility in managing different terminal groups.
Solution Approach 2:
The interface node enables self-service management by automatically identifying terminals that need updates, distributing software and configuration files, and managing terminal subsets without human intervention. The system autonomously handles the entire upgrade and management process.
2Productivity
If software upgrades are performed on mobile terminals during operation, then operational continuity is improved, but system stability and reliability worsen due to potential interruptions
Solution Approach 1:
The interface node prepares software upgrades and configuration updates in advance, staging them locally before deployment. Terminals receive updates during docking periods when they are stationary and can safely perform reprogramming operations, ensuring both operational continuity and system stability.
3Loss of information
If frequent communications are made between the resource network and large fleets of terminals, then real-time status monitoring is improved, but network traffic and data transmission loads worsen
Solution Approach 1:
The interface node acts as a local intermediary that maintains status information for all terminals locally. Instead of each terminal communicating directly with the resource network, the interface node aggregates status data and communicates with the resource network only when necessary, dramatically reducing network traffic while maintaining real-time monitoring capability.
