What Data for This Category Looks Like
Data sources for general equipment intelligent due diligence reports include factory-issued technical documents from manufacturers, third-party industry test reports, equipment operation and maintenance logs, and bidding technical documents. Update frequency aligns with new equipment launches, annual operation and maintenance inspections, and project bidding cycles. Document structures typically include structured parameter tables, text-and-image technical descriptions, and appendices of compliance test items. Core fields include rated power, operating weight, rotational speed, and similar metrics. Corresponding units are professional engineering units such as kW, t, r/min.
Constraints on Document Parsing and Chunking
Diverse data sources result in document formats including editable PDFs, encrypted docx files, and scanned documents, which increases parsing adaptation difficulty. Inconsistent update cycles lead to coexistence of multiple document versions, requiring accurate matching of version-specific parameter fields. Dense technical parameters and interleaved text and image structures in documents easily cause separation of parameters and their contextual descriptions during chunking. Specific binding relationships between engineering units and fields require retaining the association between fields and units after parsing to avoid information loss post-chunking. Large document volumes also extend parsing time and increase timeout risks.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600-900 seconds | General equipment due diligence documents often contain multi-page parameter tables and technical descriptions, with higher parsing time than general documents |
UPLOAD_FILE_MAX_SIZE | 1500 MB | Some documents embed high-definition equipment drawings, resulting in large single-file size, requiring relaxed upload limits |
maxChunkSize | 800-1200 characters | General equipment documents have dense parameters; overly long chunks will separate parameters and their corresponding technical descriptions |
chunkOverlap | 150-200 characters | Retain the association between parameters and their context, avoiding loss of binding between technical descriptions and parameters after chunking |
TABLE_PARSE_MODE | structured | Parameter table fields in general equipment documents are fixed; structured parsing can fully retain the correspondence between fields and units |
ENABLE_OCR | auto | Cover editable documents and scanned drawing scenarios, adapting to multi-format general equipment technical documents |
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 individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- A timeout error
timeout of 360000ms exceededoccurs when uploading a 10+ MB PDF for parsing. The cause is failure to adjust thePARSE_FILE_TIMEOUT_SECONDSparameter; the default timeout duration is insufficient for processing general equipment documents containing multiple parameter pages. - Some docx documents fail to parse. The cause is that embedded high-definition equipment drawings are not correctly identified, and the automatic mode of
ENABLE_OCRis not enabled. - Tables in knowledge base documents are chunked incorrectly. The cause is use of the default
unstructuredparsing mode instead of switching tostructuredmode, resulting in table fields and units being split into different chunks.
How to Verify Correct Configuration
- Upload a single large general equipment technical PDF, confirm whether the parsing task completes within the set timeout duration.
- Upload a document containing parameter tables, confirm whether the parsed chunks retain the association between parameters and their corresponding units, with no field splitting occurring.
- Review parsing task logs, confirm that GPU resources are called normally, with no video memory overflow errors.
- Compare general equipment documents of different formats, confirm that the parsing results have consistent formatting, with no parsing failures occurring.
