What the data for this category looks like
Data sources for thermal intelligent due diligence reports include thermal pipeline network operation logs, heating load monitoring reports, annual thermal supply due diligence reports, and user heating service records. Daily pipeline monitoring data updates daily. Annual due diligence reports release per fiscal year. Document structures primarily use structured tables, supplemented by parameter explanation paragraphs. Core fields include pipeline pressure, water supply temperature, return water temperature, heating area, and charging amount, with corresponding units of megapascals, degrees Celsius, square meters, and yuan.
What constraints these characteristics impose on the knowledge base retrieval and recall link
Highly structured thermal data and fixed field units require the retrieval link to support precise matching by field name and unit. This avoids irrelevant entries from generalized recall. Daily updates for routine monitoring data require the retrieval system to support incremental synchronization mechanisms. This reduces resource consumption from full synchronization. Documents include both long text explanations and tabular parameters. This requires the recall link to balance paragraph semantics and structured data within tables. Differing update frequencies between annual reports and daily data require configuring layered synchronization rules. This distinguishes update cycles for different data sources.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Number of recalled entries | Top 8-12 entries | Thermal due diligence reports have many parameter dimensions. Sufficient monitoring entries must be covered to avoid missing key parameters |
| Similarity threshold | 0.75-0.85 | Thermal parameter descriptions are relatively standardized. A too-high threshold filters synonymous parameter descriptions. A too-low threshold introduces irrelevant entries |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single thermal due diligence report may contain multi-page tables and long text. Parsing takes significant time |
maxContext | 1000-1500 characters | Field descriptions and parameter values for thermal data must be fully recalled. This avoids truncating key unit information |
| Incremental synchronization switch | Enabled | Daily thermal pipeline network data updates daily. Full synchronization consumes excessive system resources |
| Structured field matching switch | Enabled | Thermal data includes many standardized fields. Enabling this allows precise matching of parameter names and units |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. Conduct tests on local samples before finalizing settings.
Three common errors
- Phenomenon: Dynamically switching knowledge bases with global variables leads to retrieval results that do not match the specified knowledge base. Cause: The global variable is not correctly bound in the
{{datasetId}}format, or the variable is not assigned before the call. - Phenomenon: Uploading Excel or PDF files of thermal due diligence reports triggers a parsing error prompt in the interface. Cause: The file contains merged cells, encrypted content, or non-standard thermal parameter table formats.
- Phenomenon: Retrieval results cannot display thermal pipeline network topology diagrams stored in the knowledge base. Cause: The knowledge base’s image extraction configuration is not enabled, or the recall rules do not include logic to recall image fields.
How to verify the configuration is successful
- Run a simulated retrieval, input the thermal pipeline network pressure parameter, and confirm whether the recalled results include the corresponding fields and units.
- View knowledge base synchronization logs to confirm that incremental synchronization tasks run at the preset frequency with no failed records.
- Test the global variable dynamic switching function, replace the bound knowledge base ID, and confirm that retrieval results switch to the corresponding knowledge base.
- Upload a thermal due diligence report with images, and confirm whether retrieval results include displayed image-related content or links.
