What Data for This Category Looks Like
Spraying and coating scenario data covers end-to-end process information for coating lines across automotive, home appliance, construction machinery, metal furniture, and other industries. Daily generated documents include coating process cards, coating batch sheets, paint mixing records, film thickness and color difference reports, oven curves, defect repair sheets, and VOCs ledgers. Fields include film thickness measured in μm, color difference ΔE values, oven temperature in ℃, and coating viscosity in seconds, among others. Data sources include coating supplier TDS/SDS documents, real-time collection data from spray booths and ovens, test results from colorimeters and film thickness gauges, environmental monitoring records, and MES production systems. Update frequencies are as follows: batch sheets are updated per coating batch, process execution records are updated per shift, and equipment operation data is collected continuously.
Constraints on Citation and Traceability Workflows
The multi-source heterogeneous data and high-frequency update characteristics of coating scenarios impose multiple constraints on citation and traceability processes. First, data sources fall into three categories: equipment, suppliers, and production systems. Precise association with specific production batches and time windows is required to avoid mixing data across batches. Second, document types include structured reports and unstructured process files. Support for content restoration and field extraction across different formats is necessary. Third, high-frequency real-time data collection requires context recall to cover recent production records, preventing the use of expired information. Finally, coating defect analysis requires matching full-process data from pre-treatment, spraying, and curing stages. Multi-dimensional associated documents must be recalled to ensure complete traceability logic.

| Reorder Toggle | Enabled | Prioritizes recall of test data directly related to coating defects |
Three Common Configuration Mistakes
- The context citation area only displays raw text fragments separated by
|, and does not retain the original table and heading formatting of the document. This occurs because theresponseDataoriginal format retention configuration is not correctly enabled. - After submitting a question about defects in a specific coating batch, the target coating process card or film thickness and color difference report cannot be recalled. This occurs because the chunk length is set too small, causing key information to be truncated, or the single recall limit is set too low.
- Residual, unremovable citation source annotations appear in generated exception reports. This occurs because the display switch for the
detailparameter is not correctly configured, and citation content is mistakenly deleted directly from the response.
How to Verify Correct Configuration
- Upload a complete coating process card document, submit a question about process parameters, and check whether the context citation area retains the original document's table structure and unit annotations.
- Submit a question about defects in a specific coating batch, and verify that the recall results include the corresponding batch's paint mixing records and oven curve data.
- Review the generated exception report, and confirm that the citation source's file name, collection time, and production batch information are fully displayed.
- Adjust the single recall limit parameter, and verify that the number of recall results matches the preset value range.
