What This Category’s Data Looks Like
Data sources for this category include coating supplier TDS/SDS, spray booth and curing oven operating data, colorimeter/film thickness gauge test results, environmental monitoring data, and MES system records. Daily documents include coating process cards, coating batch lists, paint mixing records, film thickness and color difference reports, curing oven curves, defect repair orders, and VOCs ledgers. Data is updated per coating batch and per shift, with key operating parameters collected continuously. Document fields include dedicated parameters such as film thickness (μm), color difference ΔE, curing oven temperature (℃), and VOCs concentration (mg/m³). This page is compatible with FastGPT v4.17.0.
Constraints Imposed by These Characteristics on Multi-turn Dialogue and Prompt Engineering Workflows
Data for this category is updated per batch and per shift, and includes a large number of real-time test parameters. This requires multi-turn dialogue to bind the current job’s batch number and shift ID as context to avoid mixing data across batches. Prompts must be limited to calling only the current job’s paint mixing records, film thickness and color difference reports, and other documents, and must not introduce content from unrelated batches. Continuously collected curing oven temperature and VOCs concentration data must be linked in real time during dialogue. When generating exception reports, current environmental monitoring values must be matched. The multi-turn workflow must guide step-by-step through pre-treatment, spraying, and curing stages to avoid asking for too many scattered parameters at once.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Maximum context length | 8000–12000 characters | Matches the length of a single coating process document and the total context length of batch-based multi-turn dialogue |
| Single search limit | Top 6 results | Covers core documents for a single batch job, including process cards, paint mixing records, and three types of test reports |
| Question optimization | Enabled | Helps split complex exception analysis requests into step-by-step stages, adapting to the multi-step constraints of the coating workflow |
variables binding | Batch number, shift ID, environmental monitoring parameters | Ensures dialogue context only links to data for the current job, avoiding cross-batch confusion |
messages context retention | Last 10 dialogue turns | Covers the complete communication flow for a single batch job, including parameter follow-ups and result confirmations |
chatId association | Bound to current job session | Ensures multi-turn dialogue context is not interfered with by other job sessions |
Three Common Misconfigurations
- Symptom: A
400 Bad Requesterror is returned when calling the dialogue interface, with a prompt indicating thevariablesfield is missing. Cause: Dedicated variables such as the coating job batch number and environmental monitoring parameters were not bound, causing the system to fail to limit the context scope. - Symptom: The generated exception report references data from a previous batch’s coating batch list. Cause: The current job session was not bound via
chatId, so context was overwritten by historical dialogue from other jobs. - Symptom: The process document generated by the dialogue lacks specific parameters for film thickness and color difference. Cause: Question optimization was not enabled, and the system did not step-by-step follow up on instrument test numerical results; directly requesting a full report led to missing parameters.
How to Verify Correct Configuration
- Initiate a test dialogue, enter a description of the current batch’s coating abnormality, and verify that the returned context only includes paint mixing records and test reports for that batch.
- Call the dialogue interface, check that the request body includes the
variablesfield and is populated with dedicated parameters for the current job. - View the session’s
messageslist, confirm that the last 10 rounds of dialogue content are fully retained and no information from other jobs is included. - Trigger exception report generation, verify that the output includes dedicated category parameter fields such as film thickness, color difference, and curing oven temperature.
