What the data for this category looks like
Data related to document and material drafting for urban gas mainly comes from station inspection logs, pipeline operation ledgers, user installation archives, and safety inspection reports. Data sources cover offline inspection terminals, gas dispatch systems, and user service platforms. Update cadence includes real-time synchronization of inspection anomaly data, daily update of daily gas usage statistics, and monthly full ledger archiving. Document structure includes structured fields and unstructured attachments. Structured fields are station ID, pipeline burial depth, hazard level, and rectification deadline, with units of character, meter, enumerated value, and date respectively. Unstructured attachments include on-site hazard photos and rectification plan documents.
What constraints these characteristics impose on workflow orchestration
The mixed data structure and multi-frequency update features of urban gas impose multiple constraints on workflow orchestration. The document structure with both structured fields and unstructured attachments requires the workflow to configure a node sequence that first extracts structured fields, then associates corresponding unstructured attachments. Data sources with multiple update cadences require the workflow to support two modes: fixed-cycle trigger and event trigger. These modes adapt to monthly ledger organization and real-time rectification document generation respectively. Industry documents must strictly match required fields from official templates, so the workflow must embed a field validation step to avoid missing key information. Dispersed multiple data sources require the workflow to configure multiple nodes to pull data from different systems, complete unified integration, then enter the document generation link.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Variable configuration | Preset three variables for station ID, hazard level, rectification deadline, and bind them to corresponding data source fields | Matches the variable binding logic of FastGPT v4.17.0, matches required fields for gas documents, ensures generated content complies with template requirements |
| Node ID | Assign nodeId in the order of data source pull, field validation, document generation | Clearly distinguishes each workflow link, facilitates debugging and error location |
| Knowledge base selection | Bind urban gas safety specifications and document template library, recall top 5 entries per request | Covers industry-specific gas specifications and standard templates, improves compliance of generated content |
| Timeout setting | 600 seconds | Adapts to time requirements of multi-data-source pull and long document generation |
| Context length | 800–1200 characters | Balances detail completeness of document generation and computing costs |
| Tool call retry | Retry 3 times after failure | Avoids resource consumption from invalid calls, ensures workflow execution stability |
Three common mistakes
- Document content returned during debugging has no relation to the actual input station data, and preset fields are not populated. The cause is failure to correctly bind
variablesto data source fields, leading to incorrect variable assignment. - A timeout error pops up during workflow execution, with status code 504. The cause is that the timeout setting value is too small, failing to adapt to the time requirements of multi-data-source pull.
- Tool calls in advanced orchestration have no response, and subsequent document generation nodes cannot be triggered. The cause is that
nodeIdis not configured in order, leading to chaotic workflow node execution logic.
How to confirm the configuration is correct
- Open the workflow debugging panel, enter simulated station ID and hazard level, check if
variablescorrectly load corresponding field values. - Manually trigger the workflow, view node execution logs, confirm that the execution order of each
nodeIdmatches the preset. - Generate a test document, verify that all preset required fields are included and the content complies with gas industry specifications.
- Simulate triggering the workflow three consecutive times, check if tool calls retry according to the preset number of times, with no abnormal errors.
