What This Category’s Data Looks Like
Data for this category originates from design documents, standard instruments, environmental monitoring data, calibration software, laboratory information systems, and customer range requirements. Daily documentation includes assembly and commissioning sheets, calibration procedures, original calibration records, error curves, metrology certificates, and software version logs. Data is updated for each device immediately after every calibration. Data fields include tested part number, calibration environmental parameters, error calculation results, and traceability chain information. These fields must align with metrological traceability requirements. Calibration records serve as the core deliverables, differing from standard devices that only verify functionality.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
This category’s data is updated once per device per calibration, and fields must meet metrological traceability requirements. This creates multiple constraints for HTTP interfaces. Interfaces must support precise data retrieval by device number and calibration batch, to avoid returning unrelated records. As calibration records are core deliverables, the responseData returned by the interface must include complete fields such as traceability chain and error curves, and cannot be simplified. Data comes from external tools including laboratory information systems, so interfaces must comply with identity verification requirements for cross-system calls. Error returns must clearly correspond to scenarios where metrological audit fails.
Configuration Reference for FastGPT v4.17.0
Reference configuration items are listed below:
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {API key generated by the laboratory system} | Data for this category involves metrological traceability, so strict identity verification is required to prevent unauthorized calls from tampering with calibration records |
variables | ["deviceId", "calibrationBatch", "environmentParams"] | Unique device identifier, calibration batch, and environmental parameters must be passed to accurately match the corresponding calibration records |
responseData | Complete field set including deviceId, calibrationTime, errorCurve, certificateNo | Calibration records are core deliverables, so all fields required for metrological audit must be returned |
| Timeout Duration | 300–600 seconds | The multi-point collection and error calculation process takes a long time, so sufficient response time must be reserved |
| Call Frequency Limit | No more than 100 calls per device per day | Calibration data updates infrequently, high-frequency calls have no practical value and increase system load |
Three Common Misconfigurations
- Phenomenon: When an external platform calls the interface, the
variablesfield is empty or does not carry the expected device number parameter. Cause: The transfer rules for global variables are not configured in the FastGPT orchestration workflow, preventing external calls from passing business parameters. - Phenomenon: The
responseDatareturned after calling the interface lacks error curve or metrology certificate number fields. Cause: Complete calibration record fields are not specified in the interface configuration, and only simplified data is returned, which fails to meet metrological audit requirements. - Phenomenon: The interface call returns a 504 timeout error. Cause: The timeout duration is not set to a value matching the calibration calculation time for this category, and the default timeout period is insufficient.
How to Verify Proper Configuration
- Invoke the interface with preset deviceId and calibrationBatch parameters, and confirm whether the returned
responseDataincludes the calibration record fields for the corresponding device. - Review interface logs to confirm that the
Authorizationparameter has been correctly parsed, with no identity verification failure errors reported. - Simulate multiple interface calls, and confirm whether the
variablesparameter returned by the interface matches the passed business parameters. - Adjust the timeout duration to 300 seconds, invoke an interface that includes multi-point error calculation, and confirm that no timeout error is triggered.
