What the data for this category looks like
Data for this category comes from manufacturing enterprise EHS departments and inspection and maintenance teams. Daily documents include risk identification records, work tickets such as hot work and confined space entry, environmental monitoring records, hazardous waste ledgers, and accident rectification reports. Data sources include industry regulatory standards, online environmental monitoring systems, gas detectors, personnel qualification files, equipment isolation lists, and regulatory platforms. Updates happen in real time as work proceeds, periodically per monitoring requirements, or immediately after a single work task is completed. Document structures vary widely, ranging from linear process text to structured tables. Fields include work approval numbers, gas concentration values, qualification validity periods, and more, with exclusive units such as ppm, cubic meters, and days.
What Constraints These Characteristics Impose on Document Parsing and Chunking
The structural differences between multiple document types require chunking rules to adapt to both linear text and structured tables, to avoid splitting work ticket approval nodes or field associations in hazardous waste ledgers. Real-time and high-frequency updated documents require parsing tools to quickly adapt to exported files of different formats, to avoid field loss due to format incompatibility. Exclusive fields and units require retaining contextual associations during chunking, to ensure complete work processes and data logic can be traced during cross-review. Mixed formats of monitoring data exported from equipment and manually entered work tickets require parsing tools to support both standardized and non-standardized documents.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the text length of work tickets and ledgers, retains the integrity of approval nodes and field associations |
chunkSplitter | Separate by paragraph + table header | Adapts to multi-format documents, avoids splitting work ticket approval processes or the table structure of hazardous waste ledgers |
customPdfParse | Enabled | Adapts to PDF monitoring reports exported from equipment, retains positional associations between original tables and fields |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Accommodates batch-uploaded annual hazardous waste ledgers or quarterly emission monitoring reports |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Avoids triggering timeout limits when parsing large-volume monitoring reports |
chunkSettingMode | Manual configuration | Adjust chunking rules for different document types, adapts to structural differences between work tickets and ledgers |
Three Common Configuration Errors
- When uploading a large hazardous waste ledger PDF, an "offset out of range" error pops up at 90% progress. The cause is failure to adjust
UPLOAD_FILE_MAX_SIZEorPARSE_FILE_TIMEOUT_SECONDS, triggering system resource limits during large file parsing. - When uploading hot work ticket documents via the create file collection API, the chunking results differ from those of the same document uploaded directly through the platform. The cause is failure to unify the
chunkSettingModeconfiguration. API calls use the automatic chunking rule by default, which does not match the parameters configured manually in the interface. - After configuring a custom parsing URL, uploading a document returns no parsed data. The cause is failure to enable
customPdfParse, the custom parsing tool not adapting to the table and field association structure in EHS documents, or incorrect passing of document format information via URL parameters.
How to Verify Correct Configuration
This page's configuration applies to FastGPT v4.17.0.
- Upload a single 100MB annual emission monitoring PDF, verify that the parsing progress has no timeout or offset errors.
- Upload the same confined space entry work ticket via API and the interface separately, compare the paragraph integrity and field associations in the chunking results.
- After enabling
customPdfParse, upload a PDF report exported from a gas detector, verify that table fields are not split or lost. - Check that the
UPLOAD_FILE_MAX_SIZEconfiguration covers the current maximum single-file volume requirement.
