Measurement Data Traceability Using UID and Checksum Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an effective and traceable scheme for managing and reporting measurement data, particularly from RF measurement devices, making it difficult to record and verify the circumstances under which data and results were obtained.
Innovation Solution
A system and method that utilize unique identifiers (UIDs) and checksums to link configuration settings with measurement results, ensuring traceability and consistency, and optionally using signing certificates for legal binding, facilitating seamless cloud integration and online reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distributed and network based data processing is used for measurement data management, then data accessibility and offline processing capability are improved, but traceability of measurement circumstances and verification of measurement conditions deteriorate
Solution Approach 1:
The system performs preliminary actions by generating configuration checksums and result checksums at the time of measurement configuration and result acquisition. These checksums are stored in association with the measurement data before any distributed processing occurs, ensuring that traceability information is captured and preserved independently of subsequent data access or processing operations.
Solution Approach 2:
The system implements feedback mechanisms by verifying measurement circumstances through checksum validation. When measurement results are retrieved or processed, the system can verify the configuration checksum against the result checksum to confirm that the measurement was performed under the recorded conditions, providing continuous traceability feedback in the distributed environment.
2Adaptability or versatility
If historical measurement data is stored and retrieved for reporting, then data re-analysis capability is improved, but verification of measurement consistency and legal binding deteriorate
Solution Approach 1:
The system creates copies of critical measurement information in the form of configuration checksums and result checksums. These checksum copies enable re-analysis of historical measurement data while maintaining verification capability, as the checksum copies can be independently validated to confirm measurement consistency without requiring access to the original measurement instrument or environment.
Solution Approach 2:
The system performs preliminary validation by generating and storing checksums at the time of measurement. This preliminary action ensures that when historical data is retrieved for re-analysis, the measurement consistency can be verified through checksum comparison, providing legal binding assurance independent of when or how the data is accessed.
3Productivity
If measurement configuration and results are managed separately, then data processing efficiency is improved, but integration and traceability between configuration and results deteriorate
Solution Approach 1:
The system introduces checksums as intermediary elements that bridge the gap between measurement configuration and results. The configuration checksum represents the configuration state, and the result checksum represents the measurement outcome. By associating these checksums, the system maintains efficient separate processing of configuration and results while preserving the critical linkage information needed for traceability and verification.
Data Source
AI summary
A system for measurement management is configured to obtain a configuration set and an associated configuration unique identifier (UID). The system is also configured to obtain at least one measurement result and an associated result UID. A relation between the configuration UID and the result UID is determined, and the relation is stored.
