What this category of data looks like
Data for railway operations inquiries and responses comes from official customer service ticket systems, 12306 platform inquiry logs, and on-site station service records. Updates follow this schedule: daily updates for hot inquiries on regular days, real-time updates for temporary operation information during holidays and timetable adjustments. Document structure includes inquiry classification tags, problem keywords, standard responses, applicable scenarios, effective date, and associated train/station code fields. For field units: effective date uses the YYYY-MM-DD format, associated trains use letter-plus-number combinations, and inquiry classifications use fixed text options.
What constraints these characteristics impose on forms and interactions
Real-time data updates require dynamic form options to sync with official data sources at scheduled intervals. This prevents returning outdated train or rule information. Multi-category inquiry structures require forms to switch input items based on first-level classifications. For example, ticket purchase inquiries display an ID number input field. Ticket refund inquiries display an order number input field. Fixed field format requirements demand that corresponding validation rules are configured for formInput. This ensures input content complies with railway operation data format specifications. The need to associate historical conversation data requires configuring context prompts. These prompts help users input questions accurately.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput format validation | Bind corresponding formats based on inquiry type, e.g., train number validation as [G/D/C/Z/T/K]+[0-9]{1,6} | Matches the train number field format requirements in railway operation inquiry data |
| Dynamic option loading | Sync with official railway data sources every 300 seconds | Adapts to the real-time data update rhythm, balancing performance and timeliness |
userSelect first-level classification | Preset 5-8 first-level classifications, such as ticket purchase, ticket refund, ticket change | Aligns with the first-level classification structure of inquiry data, simplifying user input |
| Form submission timeout | 600 seconds | Matches the average response duration of official railway data synchronization |
| Context association prompt | Bind the first 3 entries of historical inquiry records | Adapts to the context association requirements of customer service conversation data |

Three common configuration errors
- Symptom: The voice input button fails to trigger, and the browser console displays "Voice input API unavailable". Cause: Non-native voice input fallback mode is not enabled in the
formInputconfiguration, and only the browser's native voice input interface is used. - Symptom: After selecting a knowledge base, the reference variable dropdown box is empty with no selectable values. Cause: The knowledge base's field mapping is not bound to form input items, so the system cannot identify matching optional variables.
- Symptom: A timeout error is returned after form submission, with a status code of 504. Cause: No reasonable timeout threshold is set, or no data synchronization retry mechanism is configured, causing requests to exceed the system's waiting limit.
How to confirm the configuration is complete
- Switch between different inquiry classifications, and check whether form input items automatically switch to corresponding format validation rules.
- View the dynamically loaded train number option list, and confirm that the latest operation data is updated every 300 seconds.
- Disable the browser's native voice input function, click the voice input button, and confirm that the alternative input method is invoked.
- Select a knowledge base corresponding to a classification, and check whether the reference variable dropdown box displays matching field options.
