Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing field devices and expansion modules for automation technology, particularly in logistics and factory automation, face challenges with incorrect configuration due to country-specific radio interface requirements, which is not compatible with autonomous and mobile operations.
Innovation Solution
A field device and expansion module with a position determination means that automatically selects the appropriate radio communication operating mode based on geographical location, allowing for universal usability across different regions and reducing the need for manual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of radio interface parameters is performed for each country-specific region, then the field device can meet local regulatory requirements, but the commissioning process becomes time-consuming and error-prone
Solution Approach 1:
The field device automatically determines its geographical position using GPS/GLONASS coordinates and autonomously selects the appropriate LoRaWAN regional parameters without requiring manual configuration by commissioning personnel. The device serves itself by retrieving position data, matching it with stored region definitions, and applying the correct radio interface settings automatically.
Solution Approach 2:
All possible LoRaWAN regional parameter sets for different countries and regions are pre-configured and stored in the field device's memory before deployment. When the device operates, it simply needs to identify which pre-stored parameter set matches its current position, eliminating the need for real-time configuration during commissioning.
2Adaptability or versatility
If the field device continuously determines its position to ensure correct radio operation, then the operating mode can be always optimized for the current location, but energy consumption increases
Solution Approach 1:
Instead of continuously determining position, the field device performs position determination periodically or at specific trigger events such as when the device is first powered on, when it detects movement, or when it enters a new geographical region. This periodic approach maintains adaptability while significantly reducing energy consumption compared to continuous position tracking.
Solution Approach 2:
The field device dynamically adjusts its position determination strategy based on operational context. It can switch between active position determination and using previously determined positions, depending on whether the device is mobile or stationary, and whether it has recently moved. This dynamic approach optimizes the balance between adaptability and energy efficiency.
