What this category of data looks like
Coal chemical industry ledger data primarily comes from production DCS control systems, offline laboratory reports, and equipment operation and maintenance logs. Production process ledgers update every 15 minutes. Offline quality inspection data updates three times per production shift daily. Equipment operation and maintenance ledgers update monthly. Each ledger document includes fields such as equipment number, process parameters (furnace temperature, furnace pressure, circulating water flow), material consumption, quality inspection indicators, and operation and maintenance records. Furnace temperature is measured in degrees Celsius, flow is measured in cubic meters per hour, and material consumption is measured in tons. Each record has a timestamp precise to the minute and affiliated shift information. Reference only; verify against the target FastGPT release and deployment documentation.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
The high-frequency updates of coal chemical industry ledger data require HTTP interface request intervals to not exceed 15 minutes, otherwise real-time process parameter changes cannot be covered. Requirements for multiple fields and specific units mean interface return fields must strictly match the preset ledger structure, to avoid ledger summary errors caused by missing fields or incorrect units. The timestamp of each record is precise to the minute, so the interface must support minute-level time range filter parameters to ensure accurate data pull intervals. The volume of ledger data increases with production scale, so the number of items returned in a single interface call must be limited to a reasonable range, to avoid timeouts or transmission failures caused by excessive data volume.
How to configure
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer ${coal chemical internal API key} | Matches the interface authentication rules of coal chemical production systems, ensuring legitimate request permissions |
variables | {"start_time": "example value", "end_time": "example value"} | Pulls real-time process ledger data from the last hour, adapts to the 15-minute update frequency |
responseData | Return only core ledger fields | Reduces response content and transmission overhead, adapts to the bulk pull requirements of coal chemical industry ledgers |
| Timeout setting | 600 seconds | Adapts to the typical response duration of coal chemical production system interfaces, prevents request failures from network fluctuations |
| Field validation | Enable required field validation | Ensures interface returns include core ledger fields such as equipment number, furnace temperature, and timestamp, avoiding summary errors |
| Retry mechanism | Retry 2 times after failure | Addresses occasional fluctuations in coal chemical production networks, improving interface call success rates |
Three common configuration mistakes
- Phenomenon: Interface return results and AI-generated content appear together in the final reply, and the interface displays context duplication or field conflict prompts. Cause: No direct output rule for
responseDatais configured, the default AI generation process is retained, and the native AI reply logic is not skipped. - Phenomenon: The ledger summary report does not use the latest interface return data, and still relies on old knowledge base content. Cause: The HTTP return result is not imported into the temporary knowledge base, and the rule that uses interface data as the analysis basis is not configured.
- Phenomenon: Interface requests trigger timeout errors, returning status code 504 or request timeout prompts. Cause: No reasonable timeout duration is set, and the response delay of coal chemical production system interfaces is not adapted, causing requests to be interrupted before completion.
How to confirm the configuration is complete
- Send a test request, check whether the interface return fields include core ledger fields, and verify that units match the preset coal chemical industry ledger standards.
- View call logs to confirm that request intervals meet the preset cycle, there are no frequent timeout or failure records, and verify the stability of interface calls.
- Trigger the ledger summary and report generation process, confirm that the final report only includes interface return data, with no additional AI-generated wording or redundant content.
- Adjust the time range parameter in
variables, verify that the data interval returned by the interface matches the set parameters, and ensure the time filter logic is correct.
