Linked Test Signal Records for Reliable Cross-Device Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test information management systems in plants lack integration of first and second device information, leading to difficulties in ensuring the reliability of tests, as they rely on manual recording and individual worker judgments, which can result in errors.
Innovation Solution
A test information management device that automatically links first information, representing the output state of a test signal from a first device, with second information, including image information of reception results from a second device, using identification information and timestamps, to ensure traceability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test information is managed separately according to work content in different devices, then each worker can independently record and manage their own test data, but the reliability of the overall test cannot be ensured due to lack of integration and potential human errors
Solution Approach 1:
The patent merges test information from multiple devices (device maintenance apparatus and monitoring device) into a single integrated management system. The test information management device consolidates first information (test signal output state) and second information (reception result) that were previously managed separately, creating a unified test record that ensures reliability through integration while maintaining manageable complexity through automated processing.
Solution Approach 2:
The test information management device acts as an intermediary between the device maintenance apparatus and the monitoring device. It receives test information from both devices, links them together using identification information and timestamps, and manages the integrated data, thereby resolving the complexity of direct integration while ensuring test reliability through centralized management.
2Measurement precision
If manual recording and individual worker judgments are used for test results, then each worker can independently document their observations, but errors may occur and traceability becomes difficult
Solution Approach 1:
The system enables automatic recording of test information without manual intervention. The device maintenance apparatus automatically generates first information about the test signal output state, and the monitoring device automatically captures second information about reception results. This self-service approach eliminates manual recording errors and reduces the time required for documentation and verification.
Solution Approach 2:
The system establishes a feedback loop where test information is automatically captured, linked, and managed. The identification information and timestamps provide immediate feedback about the test state, allowing for real-time verification and traceability without manual intervention, thereby improving accuracy and reducing time loss.
3Reliability
If test information from multiple devices is integrated using identification information and timestamps, then traceability and reliability are enhanced, but the complexity of information linkage increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing identification information for each device and pre-formatting test data with timestamps before integration. This preliminary preparation simplifies the linkage process, as the test information management device can directly connect pre-identified data elements without complex real-time processing, thereby enhancing reliability while managing complexity.

AI summary
A test information management device manages test information relating to a test carried out by receiving a test signal output from a first device in a second device. The test information management device includes a linker configured to link together first information including information representing an output state of the test signal in the first device and second information including image information representing reception results of the test signal in the second device using at least one of identification information for identifying the first device or the second device and times at which the first information and the second information are generated.
