What this category of data looks like
Data sources include wood pulp and waste paper batch ledgers, DCS/QCS systems, on-paper machine measurement devices, laboratory test reports, energy and water treatment systems. Daily stored documents include pulp preparation sheets, beating records, paper machine operation logs, online quality curves, sheet break and product change records. Data update frequencies cover real-time (paper machine operation parameters), per-shift (team inspection records), and per-roll (finished paper quality batch data). Fields include pulp mix ratio, beating degree, sheet grammage, moisture content, and others. Some continuous data such as online quality curves are frame-by-frame collected width parameters.
What constraints these characteristics impose on HTTP interfaces and external systems
Real-time paper machine operation parameters require the interface to support low-latency responses. Delayed data will disrupt inspection judgments. Per-roll finished paper batch data requires the interface to carry unique paper roll identifiers for association. This ensures maintenance records are bound to the corresponding production batch. Large volumes of continuous online quality curve data require the interface to support batch data transmission or streaming upload logic. Data formats vary significantly across sources. DCS systems output structured numerical data. Laboratory reports are semi-structured documents. The interface must support requests and responses in multiple formats. Cross-departmental inspection and maintenance data requires cross-system synchronization. The interface must be configured with corresponding permission verification rules.
How to set up configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer {internal enterprise API key} | Adapts to the identity verification requirements of internal production systems in pulp and paper enterprises, preventing unauthorized access to sensitive production data |
variables | {"paperRollId": "", "shiftTime": ""} | Binds unique paper roll identifiers and shift time variables, associating corresponding batch pulp preparation, beating, and inspection records |
| Interface timeout period | 30–60 seconds | Adapts to interface response requirements for real-time operation parameters and batch quality curve data, avoiding data transmission delays |
| Request retry count | 2 times | Addresses temporary interface call failures caused by network fluctuations, reducing the risk of interruptions to inspection and maintenance Q&A |
| Single upload data size limit | 100 MB | Adapts to transmission requirements for large-volume data such as online quality curves, preventing backend resource exhaustion |
responseData | Only return matching maintenance steps, inspection thresholds | Filters redundant data, adapting to the needs of quick calls and result parsing in equipment inspection scenarios |
Three common mistakes
- Scenario: When uploading offline inspection records or online quality curve data via the HTTP interface, the agent backend experiences freezes or timeout errors. Cause: Batch data is not split into chunks. The single batch upload data volume exceeds the interface's allowed load threshold, leading to backend resource exhaustion.
- Scenario: When calling text2sql to generate query statements for pulp preparation sheets or beating records, empty results or syntax errors are returned. Cause: Correct paper roll ID or shift time variables are not bound in
variables. This causes the SQL query scope to not match the actual data table structure of the pulp and paper enterprise. - Scenario: After publishing the API generated by the workflow, external system calls return a 401 Unauthorized error. Cause: The key format for the
Authorizationparameter is not configured correctly, leading to identity verification failure.
How to confirm the configuration is correct
- Call the test interface with a known paper roll ID. Check if the returned results include associated business data such as pulp preparation sheets and beating records for the corresponding batch.
- Simulate real-time parameter upload. Verify that the interface response time meets the preset 30–60 second threshold, with no timeout errors.
- Check that the format of the
Authorizationparameter is correct. Call the interface to confirm a 200 status code is returned, with no unauthorized errors. - Trigger text2sql to generate a query statement. Verify that the generated SQL matches the data table structure of the pulp and paper enterprise's equipment inspection database.
