What Data for This Category Looks Like
Spinning and weaving enterprises’ daily data includes cotton blending or ingredient lists, process setup sheets, equipment operation records, yarn inspection, grey fabric inspection, defect records and other documents. Data sources include raw fiber inspection reports, ERP systems, real-time data from spinning machines and looms, evenness tester results, fabric inspection machine test results, and order specification requirements. Data is updated synchronously per batch of raw materials, per production shift, and per piece of fabric produced. Fields include fiber fineness (dtex), cotton blending ratio (%), spinning twist (twists per meter), defect type, occurrence location (piece number and meterage), and some fields use dedicated units.
Constraints Imposed by These Characteristics on Multi-turn Dialogue and Prompt Engineering
Data for this category is split by batch, shift, and piece number, with high update frequency. Therefore, multi-turn dialogue context must be limited to the current production cycle to avoid interference from cross-batch data on analysis results. Data types cover process parameters, equipment operation, and quality inspection documents. Prompts must clearly specify the scope of documents to retrieve, preventing the model from calling irrelevant equipment operation records. Fields have dedicated units and unique identifiers. During multi-turn dialogue, variables such as piece number and batch number must be consistently bound to ensure each retrieval accurately matches data related to the current production object.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind the unique identifier of current piece number + shift | Used to associate the exclusive knowledge base and historical dialogue context for this production unit. FastGPT v4.17.0 supports direct binding of business fields |
messages | Retain the most recent 20 rounds of dialogue content, filter history older than 72 hours | Adapts to the update rhythm of per-batch raw materials and per-shift production, avoiding redundant context occupying dialogue resources |
variables | Bind three business fields: piece number, raw material batch number, and shift | Used to automatically narrow the retrieval scope during multi-turn dialogue, matching process and inspection documents for the corresponding batch |
| Reference content template | Prioritize retrieving two types of documents: "defect records" and "process setup sheets", sort by piece number in ascending order | Aligns with core needs of spinning and weaving quality traceability, filtering out unnecessary equipment operation records |
| Reference template prompt | Add the restriction "Only use document content corresponding to the current piece number to answer" | Prevents the model from calling cross-batch historical data, ensuring accurate traceability results |
| Single search limit | Top 8 matching results | Adapts to the volume of defect records for a single piece of fabric, avoiding excessive irrelevant content interfering with analysis |
Three Common Misconfigurations
- Phenomenon: Dialogue return results include defect records not associated with the current piece number, and some inspection fields are empty. Cause: The piece number field in
variablesis not bound in the configuration, and the document retrieval scope is not limited. - Phenomenon: Knowledge base retrieval returns all document types, without filtering core process and inspection data. Cause: No document type filtering rule is configured for the reference content template, resulting in an overly large retrieval scope.
- Phenomenon: A context overflow error occurs after 15 rounds of multi-turn dialogue, with a prompt indicating the context length limit has been exceeded on the interface. Cause: The number of dialogue rounds and time range retained for
messagesis not restricted, causing accumulated historical dialogue to occupy excessive system resources.
How to Verify Proper Configuration
- Enter "View defect records for current piece number P20240512001", verify that the returned results only include inspection documents for this piece number.
- Adjust the piece number in
variablesto another batch number, confirm that the returned results automatically switch to process and inspection data for the corresponding batch. - Launch 15 consecutive rounds of dialogue related to the current batch, confirm that no expired historical batch data appears in the context.
- View the knowledge base retrieval log, confirm that only the two specified document types, "defect records" and "process setup sheets", are called.
