What the data for this category looks like
Gas yield rate and market data mainly comes from public utility industry regulatory platforms, regional gas trading centers, and public channels of upstream gas suppliers. Data is updated once daily, covering price changes and yield calculation results from the current day’s trading sessions. Each data document includes fields such as category identifier, trading market, daily benchmark price, cost linkage coefficient, and regional supply gap proportion. The unit of benchmark price is yuan/cubic meter, the cost linkage coefficient is a dimensionless ratio, and the supply gap proportion is marked as a relative ratio.
Constraints Imposed on Deployment and Upgrade
The daily updated data source requires configuring an accurate scheduled sync interval during deployment to avoid data lag or duplicate pulls. The multi-field structure requires precise mapping between fields and knowledge base templates during indexing to prevent missing fields or matching deviations during retrieval. Regional differences in data source formats require compatibility with multiple sets of interface return structures during upgrades, and parsing rules for new fields must be configured in advance. Additionally, the unit consistency requirement for gas data requires presetting unit conversion rules during deployment to avoid unit confusion in retrieval results.
Configuration Parameters
| Config Item | Suggested Value | Rationale |
|---|---|---|
DATA_SYNC_CRON | 0 8 * * * | Matches the daily 8 AM update schedule for gas data, ensures that the day’s data is synchronized before broadcasting |
SIMILARITY_THRESHOLD | 0.72–0.78 | Balances precise matching and recall coverage for gas data fields, prevents irrelevant regional data from being recalled |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the number of fields and parsing complexity of gas data documents, avoids timeout errors when parsing large daily reports |
FIELD_MAPPING_RULES | Map by region and category grouping | Matches the structural differences of gas data fields across multiple regions and categories, ensures aggregation by business dimension during retrieval |
DATA_SOURCE_API_TIMEOUT | 15 seconds | Adapts to the interface response speed of public utility data sources, prevents sync tasks from being interrupted by timeouts |
MAX_RECALL_ITEMS | Top 6 items | Limits the number of gas data entries returned per retrieval, avoids overloading broadcast content |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test against your own samples before finalizing.
Three Common Configuration Errors
- After upgrading from 4.9.0 to 4.9.3, previously queryable gas market data can no longer be retrieved, and the interface displays no matching results. Cause: The default indexing rules change after the upgrade, and vector indexes for existing gas data documents are not regenerated. A full index must be manually triggered.
- After configuring the
AI_PROXYparameter during deployment, interface calls return a 403 Forbidden error. Cause: The proxy whitelist is not configured correctly, or the proxy service does not open access permissions for the corresponding data source. - After embedding FastGPT speech recognition bubbles into a third-party webpage, a permission denied prompt is triggered. Cause: The
FE_DOMAINparameter is not configured correctly, and the third-party webpage domain name is not added to the allowed cross-origin list.
How to Confirm Successful Configuration
- Manually trigger a data sync task, check whether there are field parsing failure or timeout errors in the sync logs.
- Initiate a retrieval for gas yield rate, verify that the returned fields match the preset mapping rules.
- Check the cross-domain configuration items, use a third-party webpage embedding test tool to verify that the permission requests for the speech bubbles work normally.
- View the index status of the knowledge base, confirm that the indexing progress for gas data documents has reached 100%.
