What Data Looks Like for This Category
Data for this category primarily comes from highway maintenance management systems, bridge and tunnel monitoring systems, road patrol inspection systems, and traffic flow monitoring data. Daily generated documents include maintenance plans, patrol logs, defect disposal orders, road construction permits, and road property damage compensation forms. Document structures typically include fields such as road section identifiers, operation time periods, responsible entities, and approval numbers. Units involved include kilometers, square meters, person-times, and others. The data update frequency is daily, with a single update covering that day’s new patrol records, maintenance work orders, and approval documents.
What Constraints These Characteristics Impose on Workflow Orchestration
This category’s data is multi-source, heterogeneous, and updated daily. It covers both structured approval documents and unstructured patrol records, creating multiple constraints for workflow orchestration. First, the daily data update requirement means workflow knowledge base sync tasks must use daily trigger rules to ensure the timeliness of Q&A references. Second, different business documents have significant field differences. Workflows must complete data standardization before entering the Q&A stage to avoid information extraction bias. Third, policy Q&A needs to link to specific road property identifiers. Workflows must pass the variables parameter to bind core identifiers such as road section numbers and permit numbers, ensuring accurate matching of corresponding policy bases.
Configuration Settings
These configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Global variable configuration | Bind road section number and permit number as required variables | Policy Q&A requires linking to specific road property identifiers to ensure accurate matching of corresponding policy bases |
| Text content extraction component | Enable structured field extraction mode, set extraction range based on actual testing | Category documents include structured approval forms and unstructured patrol logs, requiring adaptation to different formats |
| Workflow trigger rule | Set knowledge base sync to trigger daily between 2:00 and 4:00 AM | Data is updated daily, running during low-traffic hours avoids occupying business system resources |
| Node timeout setting | 600 seconds | Cross-system calls for maintenance and road administration data require sufficient response time |
| Single search limit | Top 10 results | Policy references need to cover relevant clauses, too many results increase context redundancy |
nodeId binding configuration | Associate the nodeId of the knowledge base Q&A node with the business data node | Ensures Q&A results can be traced back to specific business documents, improving the credibility of references |
Three Common Misconfigurations
- Symptom: After the workflow runs, it returns empty knowledge base information extraction, and the interface shows no matching results. Cause: Structured field extraction mode is not enabled, unable to adapt to the structured field format of category documents, resulting in failure to extract valid policy references from the knowledge base.
- Symptom: After switching to a workflow that does not require global variables, the system still validates the required
variablesparameter from the previous workflow, triggering a configuration error. Cause: Global variable configurations cached by the workflow are not cleared, and historical parameter validation rules are retained during cross-workflow calls. - Symptom: The text content extraction component cannot extract content from knowledge base references, and the component parameter list has no knowledge base reference option. Cause: The knowledge base node is not configured as a data source that can be referenced by the extraction component, and the node permission opening setting is not enabled.
How to Confirm Proper Configuration
- Manually trigger the workflow, enter a policy consultation question that includes a specific road section number, and check whether the returned result is linked to the maintenance or road administration policy documents for the corresponding road section.
- Check the global variable configuration panel, confirm that the
variablesparameter has been bound to the core identifier fields required by the category, with no redundant unused variables. - View the workflow trigger logs, confirm that the knowledge base sync task runs daily at the preset time, with no failed records.
- Test the text content extraction component, pass structured approval form and unstructured patrol log samples separately, and check whether the extracted fields match the structural characteristics of category documents.
