What This Category of Data Looks Like
Data mainly comes from expressway toll systems, road law enforcement ledgers, toll reduction application databases, and overload detection records. Updates follow daily business generation, with either real-time or daily batch synchronization. Documents are mostly structured forms and unstructured case files. Structured fields include vehicle license plate number, travel time period, overload weight (unit: ton), and application reason. Unstructured content includes on-site investigation records and approval circulation records.
Constraints Imposed on Workflow Orchestration by These Characteristics
Mixed structured and unstructured data types require the workflow to use dual-mode processing nodes. Each node adapts to either structured field verification or unstructured text parsing. Multi-source data synchronization requires the workflow to support cross-system data pull nodes. These nodes connect different data sources in business sequence. Fields include measured values with units. A parameter verification link must be configured in the workflow. This link ensures that units and value ranges of fields such as overload weight and travel duration comply with regulations. Approval circulation has multi-node dependencies. The workflow must set branch judgments. These judgments jump to corresponding review links based on application types.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Case file text has long length. Chunk length adapts to text semantic integrity, avoiding semantic fragmentation |
| Overlap Length | 100–150 characters | Approval circulation records in case files have cross-chunk associations. Overlap preserves context association information |
| Trigger Condition | Triggered by variables updates | Structured fields of declaration materials are updated in real time as business is submitted. This triggers the workflow to automatically execute the review process |
| Node Timeout | 600 seconds | Average time to pull road law enforcement data across systems is 300-500 seconds. This reserves reasonable buffer time |
| Node ID Binding | Bind corresponding approval links by nodeId | Accurately locate the execution order and permissions of each review node, avoiding process confusion |
| Single Recall Limit | Top 5 entries | Case file review only needs to match the latest 5 similar application records to complete compliance verification |
| Model Call Count | Calibrated based on actual testing | Adapts to case file text parsing needs of different scales, avoiding invalid calls consuming resources |
Three Common Mistakes
- After exporting and importing the workflow, referenced cross-system data plugins cannot be called normally. Phenomenon: Nodes return empty fields or status code 500. Cause: The import environment is not configured with the corresponding plugin's key and access permissions, and plugin configuration parameters are not synchronized.
- No response occurs after the workflow triggers. Phenomenon: Node status stays in pending for a long time. Cause: The
variablestrigger condition is not configured correctly, and the data source update event for declaration material submission is not bound. - Unit verification errors appear in case review results. Phenomenon: Overload weight fields are judged as abnormal. Cause: No unit verification link is configured in the workflow, and no unified conversion is performed for measured values of different units such as tons and kilograms.
How to Confirm Proper Configuration
- Manually submit a test declaration material. Check whether the workflow automatically triggers execution. Confirm that the trigger condition is configured correctly.
- View node logs. Verify that the pulled road law enforcement data fields match the source system. Confirm that the data source configuration is correct.
- Trigger the unit verification link. Enter test values of different units. Check whether the verification logic executes according to preset rules. Confirm that the verification link is configured correctly.
- Export the current workflow configuration. Import it to the test environment. Check whether all referenced plugins and parameters load normally. Confirm that the import and export configuration is correct.
