What the data for this category looks like
This category’s data covers daily business documents for enterprise metrology rooms and CNAS-accredited laboratories, including measuring tool ledgers, calibration plans, calibration certificates, interim check records, original test records, reference material ledgers, and deviation handling documents. The system sources data from metrology management systems, external calibration institution certificates, standard devices, LIMS systems, and environmental monitoring records. Updates trigger based on calibration cycles, completion of single tests, or abnormal events. Documents include fields such as instrument ID, calibration validity period, measurement uncertainty, traceability chain information, with units including specialized metrology units such as length, force, temperature, and others.
What constraints these characteristics impose on the "multi-turn dialogue and prompt words" link
Data sources for this category are scattered, and updates follow no fixed schedule. Multi-turn dialogue must first clarify the call logic for corresponding data sources to avoid using expired calibration certificates or ledger data. Document fields include specialized metrology units and complex traceability information, so prompt words must pre-design metrology term recognition rules to ensure accurate parsing of measurement values, uncertainty, and other content during dialogue. The traceability chain maintenance link requires significant time investment, requiring multi-turn dialogue to guide users to supplement instrument calibration and traceability path information in sequence, preventing missing traceability issues in generated bid documents. At the same time, the consequences of errors are severe, so dialogue must verify data compliance before generating quotations to avoid invalid bids caused by parameter errors.
How to configure the setup
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Bind measuring instrument ledger ID and calibration cycle threshold (365 days) | Used to quickly call exclusive business data for this category during dialogue, avoiding confusion across laboratory data |
messages | Concatenate in the order of "system prompt words + historical dialogue + current request", retain the most recent 20 dialogues | Avoid confusion of metrology terms caused by overly long context, adapt to step-by-step communication for multi-turn bid quotations |
chatId | Bind unique laboratory identifier and measuring instrument classification tag | Distinguish bid quotation data from different laboratories, ensure generated content complies with the metrology system requirements of the corresponding laboratory |
| Maximum context length | 8000–12000 token | Cover complete information of long texts such as calibration certificates and traceability chains, prevent truncation of key metrology parameters |
| Single dialogue return token limit | 2000–3000 token | Adapt to the needs of segmented generation of bid documents, avoid format abnormalities caused by overly long returned content |
| Question optimization switch | Enabled | Optimize metrology term questions related to bid quotations, improve retrieval and generation accuracy |
Three common configuration mistakes
- Calling the dialogue interface returns the
unAuthChatstatus code. Cause: Failed to correctly bind the API key permission exclusive to the metrology category, or failed to associate the data source permissions of LIMS and metrology management systems during key configuration. - The generated bid document contains line breaks causing JSON request failure. Cause: Failed to configure the escape rule for dialogue return content, and failed to preprocess line breaks in metrology parameters.
- Global variables fail to recognize parameters passed by the system side. Cause: Failed to bind category-exclusive parameters such as measuring instrument ID and calibration validity period to the
variablesconfiguration item, causing system parameters to fail to load correctly.
How to confirm the configuration is complete
- Initiate a test dialogue containing a specific measuring instrument ID, check whether the returned result correctly calls the calibration information of the corresponding ledger.
- Submit test text containing line breaks, check whether the generated request body is in compliant JSON format.
- View the
variablesandchatIdconfiguration items, confirm that exclusive business data parameters for the metrology category and laboratory identifiers have been bound. - Initiate multiple consecutive dialogues, check whether the context retains the most recent metrology term dialogue content without key information truncation.
