What Data for This Category Looks Like
Data sources for expressway operation service inquiries include internal ticket systems, road network dispatch platforms, officially released traffic policy documents, and customer service inquiry ledgers. Update schedules: Real-time traffic data updates every 15 minutes. Policy documents update immediately upon issuance. Ticket data is stored in real time when inquiries are submitted. Document structures: Policy documents include document numbers, effective periods, and applicable road sections. Real-time traffic data includes road section numbers and control measures. Customer service inquiries include inquiry types and response time limits. Fields include standardized road section number formats, text-described control content, and units such as hours, kilometers, and yuan. Reference only; verify against the target FastGPT release and deployment documentation.
What Constraints These Characteristics Impose on Workflow Orchestration
The high-frequency update of real-time traffic data requires matching trigger intervals to be set for the workflow’s knowledge base synchronization node. This prevents the return of outdated information. The effective period of policy documents requires adding a time verification node to the workflow. This node filters policy content that falls outside its effective range. The breakdown of inquiry types requires the workflow to split flows to corresponding knowledge bases based on fields extracted via variables. The standardized format of road section numbers requires the workflow to verify the format of input road section numbers before calling the retrieval node. This ensures accurate retrieval scope. The response time limit of customer service tickets requires setting a timeout node in the workflow. This avoids delayed or overdue responses.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Extract inquiry type and road section number as retrieval parameters | Cover core business dimensions of expressway operation service inquiries, adapt to multi-scenario flow splitting |
| Node timeout setting | 600 seconds | Match the conventional response time limit of customer service inquiries, avoid workflow timeout errors |
nodeId | Bind the knowledge base ID of the corresponding business node | Differentiate knowledge base calls for different business scenarios such as policies, traffic conditions, and tickets |
| Unrelated question trigger rule | Trigger preset fixed reply scripts | Handle scenarios where user questions are unrelated to the knowledge base |
| Synchronization frequency setting | Every 15 minutes | Match the update rhythm of real-time traffic data, ensure the timeliness of retrieved content |
| Single search limit | Top 5 entries | Avoid returning too much redundant information, optimize response speed |
Three Common Mistakes
- Phenomenon: The workflow returns a 504 timeout status code after running, and the interface displays node execution timeout. Cause: No timeout time matching the business scenario is set, or the synchronization frequency is set too high, causing node execution time to exceed the threshold.
- Phenomenon: When the user's question is unrelated to the knowledge base, AI reply results from the knowledge base are still returned. Cause: No unrelated question trigger rule is configured, or the matching threshold is set too high, causing unrelated content to also be matched.
- Phenomenon: Inquiries of different business types return mixed knowledge base content, and are not displayed split by scenario. Cause: The inquiry type field is not extracted via
variables, or the corresponding business knowledge base is not bound vianodeId, causing the split logic to fail.
How to Verify That the Configuration Is Correct
- Submit a test inquiry with a clear inquiry type, and check whether knowledge base retrieval corresponding to the target business is triggered.
- Submit a test question unrelated to the existing knowledge base, and check whether the preset fixed reply script is triggered.
- View the workflow running log, and check whether the node execution time meets the time limit requirements of the business scenario.
- Manually trigger knowledge base synchronization, and check whether the updated content is reflected in the workflow retrieval results.
