What this type of data looks like
Data sources include coal mine safety supervision management systems, production scheduling ledgers, tunneling/extraction acceptance documents, gas patrol records, and other internal business systems. Data is synced daily after each shift concludes. Quarterly file archiving is completed each month. Documents contain structured declaration forms and unstructured approval attachments. Fields include mine number, operation area, gas concentration (unit: ppm), tunneling footage (unit: meters), application items, approval node signature records, and more. The maximum size of attachments for a single declaration material can reach 800 MB.
Constraints imposed by these characteristics on multi-turn dialogue and prompt engineering
Multi-source heterogeneous data sources require multi-turn dialogue to sequentially retrieve fields from different systems such as safety supervision, scheduling, and acceptance. Prompts must clearly specify the attribution source of each field to avoid cross-system data confusion. Real-time updated production rhythms require dialogue contexts to only retain valid records from the past 72 hours. This prevents expired data from interfering with review judgments. Professional fields come with specific units. Prompts must enforce matching of corresponding units during review. For example, gas concentration must be marked with ppm, and tunneling footage must be marked with meters. Large-volume approval attachments require multi-turn dialogue file upload configurations to match business scenarios. This avoids exceeding processing capacity during single operations.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Maximum context window | Top 20 historical messages | Coal mine declaration material review logic focuses on the last 3 approval nodes. Excessively long contexts will interfere with core judgment |
messages parameter configuration | Only carry associated fields between approval nodes and current applications | Avoids irrelevant historical messages occupying conversation tokens, improves review efficiency |
variables variable binding | Bind fixed business variables such as mine number and operation area | Reduces repeated input, ensures consistency of business fields across multi-turn dialogue |
chatId parameter configuration | Bind unique identifier of current approval session | Ensures context isolation for multi-turn dialogue, avoids cross-session data confusion |
| Conversation timeout period | 600 seconds | Coal mine declaration material review processes usually require long processing times. Prevents early timeout interruptions of dialogue |
| Single conversation file upload limit | 800 MB | Matches common single-file size for coal mine approval attachments |
Three Common Misconfigurations
- An error stating "No permission to operate this conversation record" is returned in dialogue. This occurs when permission identifiers for current reviewers are not bound via
variables. This causes the permission check logic in the dialogue context to fail to match. - Reference markers are automatically appended to the end of dialogue responses. This occurs when the global configuration for dialogue references is not disabled, or rules to remove reference metadata are not specified in the
messagesparameter. - Users cannot send preset questions by clicking shortcut buttons. This occurs when preset shortcut button trigger logic is not bound in the conversation opening configuration, or the button's trigger conditions conflict with business field check rules.
How to Verify Correct Configuration
- Launch a simulated declaration dialogue. Enter preset mine numbers and operation areas. Check that bound business variables match the entered content.
- Upload a single approval attachment of common business size. Confirm no upload failure prompts appear in the dialogue interface.
- Launch a multi-turn dialogue. Enter multiple sets of approval-related content sequentially. Confirm the context retention logic matches the configured requirements.
- Click preset shortcut buttons in the conversation opening. Confirm that corresponding preset questions can be sent directly.
