IoT Gateway ID Space Conversion for Device Configuration Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT systems, existing devices without connection functions can be incorrectly configured when manually set, leading to incorrect data acquisition and analysis, as the correspondence between physical IDs and system IDs may not be maintained correctly, especially during device connection, disconnection, or re-connection, causing overlapping system IDs and erroneous device configurations.
Innovation Solution
An ID space conversion system that uses a gateway to convert physical IDs to system IDs, ensuring non-overlapping and unique system IDs by grouping devices based on regional locality or owner attributes, and verifying device configurations against design definitions to ensure correct data acquisition and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration is used for existing devices without connection functions, then device integration is achieved, but configuration errors occur leading to incorrect data acquisition
Solution Approach 1:
The system performs preliminary actions by automatically generating device configurations based on device information before data acquisition occurs. The configuration generation unit creates initial configurations using device identifiers and type information, which are then verified against design definitions to prevent errors before they affect data acquisition.
Solution Approach 2:
The verification unit provides feedback by checking generated configurations against design definitions and notifying operators of any errors. This feedback loop ensures that configuration errors are detected and corrected, maintaining reliability while enabling device integration.
2Ease of operation
If physical IDs are converted to system IDs without verification, then data acquisition is simplified, but ID correspondence errors occur
Solution Approach 1:
The system performs preliminary verification of ID correspondence by checking generated system IDs against design definitions before data acquisition begins. This ensures that the mapping between physical IDs and system IDs is accurate, maintaining measurement precision while simplifying the data acquisition process.
3Device complexity
If device configurations are not verified against design definitions, then system complexity is reduced, but statistical processing accuracy deteriorates
Solution Approach 1:
The system applies partial verification by checking only critical configuration elements against design definitions, such as device identifiers and component mappings. This selective approach maintains statistical processing accuracy without requiring complete verification of all configuration parameters, thus managing device complexity effectively.

AI summary
Provided is an ID space conversion system enabling an application to access a correct data resource by using a system ID. An ID space conversion function unit 23 generates a non-overlapping unique system ID for each type of components based on a physical ID of a component included in a device D which is determined to be a correct device by a device configuration verification function unit 22. A sharing function unit 24 shares, with a gateway 25, a gateway file f2 including a correspondence relationship between the physical ID and the system ID included in the device D. Accordingly, the gateway 25 adds, to data, the system ID, on the basis of the gateway-setting file f2, and outputs system ID-added data to a network. A data processing unit 26 determines whether component data of the device D includes the generated system ID. Accordingly, it is determined whether the data is output from the correct device D.
