What the Data for This Category Looks Like
Data for this category typically comes from highway maintenance management systems, bridge and tunnel monitoring systems, road administration patrol systems, and traffic flow monitoring data. The update frequency is daily. Daily documents include maintenance plans, patrol logs, defect disposal records, road-related construction permits, and road property damage compensation documents. These documents usually contain facility location identifiers, event types, disposal records, permit application and approval information, and compensation-related fields. Units involved include mileage, area, and time identifiers.
Constraints for Multi-turn Dialogue and Prompt Engineering
Daily updated data sources require dialogue context to link to the latest facility status data. This prevents referencing expired information. Multiple types of structured documents contain fields such as location identifiers and event types. Prompts must guide dialogue to focus on relevant information for specific highway facilities. This avoids generalized responses. In multi-turn interactions, key fields such as patrol location and construction permit status for each inquiry must be retained. variables must bind to the latest snapshots of corresponding business data. chatId must link to all historical interactions within the session to maintain context consistency.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind the unique identifier of the current session, linked to the business context of the corresponding road property facility | Maintain context consistency for multi-turn dialogue, ensuring each question is associated with previous facility information |
messages | Retain the most recent 20 interaction entries | Match the daily updated business data volume. An overly long context increases model call overhead, while an overly short context loses critical business context |
variables | Bind daily snapshots of patrol logs, maintenance plans, and other business data | Ensure business data called during dialogue is the latest version, matching the daily updated data source |
| Maximum single-dialogue timeout | 600 seconds | Cover the information retrieval duration required for business processes such as road property damage disposal and road-related construction inquiries |
| Model temperature | 0.6–0.8 | Balance the accuracy and flexibility of responses, adapting to the rigor requirements of business inquiries |
| Database connection plugin parameters | Configure a read-only permission account, limit the query scope to daily data | Prevent unauthorized access, match the daily updated data frequency, and avoid querying expired data |
Three Common Misconfigurations
- Phenomenon: Individual questions in multi-turn dialogue cannot be distinguished, and historical interactions are processed as a single group. Cause:
chatIdis not correctly bound to the session context, causing the model to fail to identify exclusive business information for each question. - Phenomenon: No temperature setting entry is found when configuring the large model, making it impossible to adjust response rigor. Cause: The advanced parameter configuration panel for model calls is not enabled, or a binding method that supports temperature adjustment is not selected.
- Phenomenon: Dialogue response content takes longer than 600 seconds, but the model call group is displayed as 1 group. Cause: A reasonable timeout threshold is not configured, or the database query scope is not limited to daily data, causing the model to retrieve excessive historical business data.
How to Verify Successful Configuration
- Launch a multi-turn inquiry that includes highway facility location and event type. Check whether the model can associate previously mentioned facility information after each question.
- Enter the model call configuration panel. Confirm that the temperature setting option exists and can be adjusted to the 0.6–0.8 range.
- Simulate a road property damage or road-related construction inquiry. Wait for the response content, and check whether the duration meets the preset threshold requirements.
- Test adding the database connection plugin. Confirm that there are no permission errors and the returned query results are the latest daily data.
