What the data for this category looks like
Spraying and coating scenario data covers multiple types of business documents and equipment collection sources. Daily business 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. Data sources include coating supplier TDS/SDS files, real-time data collected from spray booths and ovens, test data from colorimeters and film thickness gauges, workshop environmental monitoring data, and production MES systems. Update cadence follows one batch sheet update per coating batch. Paint mixing and process execution records are generated per shift. Equipment and environmental data is collected continuously. Fields include clearly labeled items with defined units: coating batch number, film thickness value (μm), oven temperature (℃), VOCs concentration (mg/m³), and similar metrics.
Constraints on Source Citation and Traceability
Multi-source heterogeneous data structures require accurate matching of associated fields across different documents during traceability. For example, link coating batch numbers to paint mixing records and film thickness reports. Data sources with varying update frequencies require aligned time windows. Match execution periods of pre-treatment, spraying, and curing processes to avoid invalid cross-timeframe associations. Core audit indicators for coating scenarios—such as film thickness, color difference, and oven curves—have clear unit and value requirements. Traceability must retain unit information from original fields. Without this, compliance audits cannot be supported. Unlike adjacent categories such as electroplating, appearance defects in coating scenarios are tightly bound to curing parameters. Traceability must prioritize linking oven curves to defect repair sheets.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Core content length of single coating business documents typically ranges from 500 to 1500 characters. This setting fully covers complete information about process parameters and test results |
responseData | Enabled | Must return associated identifiers for original business documents such as coating batch sheets and oven curves to meet traceability requirements for inspection audits |
detail | Enabled | Must display source documents for specific test values such as film thickness and color difference to match detail verification needs for audit scenarios |
| Single search limit | Top 6 results | Associated documents for coating scenarios fall into three categories: batch, equipment, and test data. Excessive results will disrupt accurate matching |
| Chunk length | 400–600 characters | Core fields of documents such as coating process cards and paint mixing records are contained within a single chunk. This chunk length avoids confusion from cross-chunk matching |
| Context window | 2000–3000 token | Adapts to traceability requirements for multi-document association in coating scenarios, covering time-related data across processes |

Three Common Misconfigurations
- The phenomenon is an error when viewing knowledge base citations. The cause is failure to properly align timestamps between oven curves and film thickness reports, leading to failed cross-document association matching.
- The phenomenon is missing specified citation content in responses. The cause is an overly small
quoteMaxTokenvalue, which fails to fully load key batch number information from coating batch sheets. - The phenomenon is redundant knowledge base search input and output content in responses. The cause is failure to disable non-essential workflow node outputs, leading to irrelevant process data being inserted during the traceability link.
How to Verify Proper Configuration
- Upload a single coating process card and its corresponding film thickness report, submit an inspection audit request, and confirm that the returned results include associated citation identifiers for both documents.
- Adjust the
quoteMaxTokenvalue to below 500 tokens, and verify that core field information from coating batch sheets can no longer be fully loaded. - Check the citation list in responses to confirm that only business-related documents such as process cards, batch sheets, and test reports are included, with no redundant workflow node data.
- Simulate a traceability query for VOCs ledgers, and confirm that the returned results include corresponding identifiers for environmental monitoring data sources.
Note: The configuration values listed here are common starting points. They should be validated against the specific samples relevant to the target deployment.
