What the data for this category looks like
Data for internal office and employee services for urban public transit comes from four main sources: public transit dispatch system, station management platform, driver attendance system, and repair work order system. Data update rhythms fall into three categories: route shift schedules are updated daily at midnight, driver attendance data is synced in real time, and station equipment fault logs are archived hourly. Each document uses standardized fields: route number, shift time, driver employee ID, equipment number, and fault description. Corresponding units are unit, hour, individual, unit, and item. Most data uses structured table format, while some equipment logs use semi-structured text.
Constraints imposed by these characteristics on forms and interactions
Since data sources are scattered across multiple independent systems, there are minor differences in field naming. Form interactions must support cross-system field mapping to avoid format errors from manual entry. The update rhythms of different data vary significantly. Real-time data requires dynamic pull logic configuration, while daily updated shift schedules need scheduled sync tasks. Most transit operation forms are linked to route and personnel information, so interaction components must support linked filtering. For example, selecting a route automatically loads the corresponding driver list. Some forms need to link historical work order data, so context call logic must be configured to quickly retrieve past records.
Configuration settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput | Bind route number and fault description fields | Adapt to the standardized entry process for public transit repair work orders, reduce manual input errors |
userSelect | Preset driver employee ID and route number option pools | Match the personnel and route binding rules of transit operations, lower entry error rates |
| Single search limit | Top 8 entries | Based on the average number of operation documents per transit route, avoid result overload that impacts interaction experience |
| Timeout threshold | 300 seconds | Adapt to network latency when retrieving transit dispatch data across systems, prevent request interruptions |
| Maximum context | 4000 token | Match the average length of transit operation documents, ensure complete recall of key information |
| Knowledge base variable parameter | Pass the route category label corresponding to the current shift | Calibrated through actual testing. Match the storage logic of transit operation documents categorized by route, enable precise recall of relevant content |
Three common misconfigurations
- Phenomenon: When calling knowledge base search, no matching documents are returned, and the interface displays "No relevant results found". Cause: The dynamically passed knowledge base variable is not bound to the current route's category label, resulting in failure to match corresponding transit operation documents.
- Phenomenon: An error occurs when passing SQL statements via variables during database connection, with status code 400 returned. Cause: Fields in transit operation data contain special characters, and no variable escaping processing is performed, leading to SQL syntax errors.
- Phenomenon: Unable to switch the knowledge base in real time during the conversation, and search results do not update after selecting an option. Cause: No dynamic option update logic is configured for the
userSelectcomponent, and it is not linked to the current shift's route information.
How to confirm the configuration is complete
- Submit a test form, check whether fields are automatically filled with corresponding transit operation data, verify that cross-system field mapping takes effect.
- Manually select different routes to trigger knowledge base search, verify that returned results match the operation documents of the corresponding route.
- Pass preset variables to call the database, check whether correct transit shift schedule or repair records are returned, verify that variable parameter passing works properly.
- Switch the current shift information, check whether the driver and route options in the
userSelectcomponent update synchronously.
