Digital Twin Registration for Cellular Industrial Device Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial automation, configuring industrial devices in a production environment is error-prone and costly due to the challenge of identifying the correct digital twin, especially when devices are deployed or replaced in a shopfloor network.
Innovation Solution
An industrial device connected to a cellular network determines its network identifier, communication identifier, and type identifier, transmitting a discover request to a management entity to automatically connect to its digital twin, allowing for the instantiation and synchronization of parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration is used to identify and connect industrial devices to their digital twins, then configuration flexibility is maintained, but error rate increases and configuration time increases
Solution Approach 1:
The industrial device automatically determines its own network address using its communication identifier and network identifier, and self-registers with the management entity without requiring manual configuration. This self-service mechanism eliminates human intervention errors and reduces configuration time.
Solution Approach 2:
The device transmits a discover request to the management entity and receives feedback in the form of a discover response containing the digital twin's network address. This feedback loop enables automatic connection establishment without manual intervention.
2Adaptability or versatility
If manual configuration adjustment is performed after device replacement, then device-specific parameters can be updated, but error propagation risk increases and operational disruption increases
Solution Approach 1:
When a device is replaced, the new device automatically determines its network address and transmits a discover request to the management entity. The management entity automatically creates or updates the digital twin and provides the new device with the correct digital twin address, eliminating manual reconfiguration errors.
Solution Approach 2:
The management entity pre-establishes the relationship between communication identifiers and digital twins. When a device connects, the relationship is automatically resolved without requiring manual configuration adjustments, ensuring configuration reliability during device replacement.
3Adaptability or versatility
If wireless communication is used to increase device mobility, then deployment flexibility improves, but device identification difficulty increases
Solution Approach 1:
The management entity acts as an intermediary that maintains the mapping between communication identifiers and digital twin network addresses. The device uses its communication identifier to request discovery from the management entity, which resolves the identification challenge in wireless environments where location changes frequently.
