What data for this category looks like
Data for this category comes from customer color samples, formula libraries, dye batch records, dye vat control systems, colorimeters, setting machines, and environmental monitoring equipment. Daily generated documents include dyeing formulas, chemical feeding ledgers, dye vat operation curves, sample confirmation sheets, color difference test reports, setting process sheets, and sewage discharge records. Data updates follow the production cycle of each vat, batch, or shift. Fields cover dye vat temperature, chemical mixing ratio, color difference values, sewage discharge volume, and more. Data is stored as structured forms or time-series curves.
What constraints these characteristics impose on workflow orchestration
Multiple heterogeneous data sources and non-standard document formats require workflow configurations with multiple nodes for data pulling and format conversion. These nodes must adapt to different access methods: device-collected time-series data, scanned paper ledger files, and online forms. High-frequency vat-level and batch-level data updates require workflow trigger nodes to use production cycle trigger rules, matching actual production rhythms. Professional parameter verification needs such as color difference values and dye vat heating curves require embedding parameter verification links in the workflow. This ensures input data complies with dyeing and finishing process standards. Severe consequences of errors require configuring exception branches in the workflow. These branches trigger corresponding processing flows for abnormal data.
How to set configurations
These configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind three core variables: dye vat number, chemical batch number, color sample number | Match vat-level and batch-level data association requirements for dyeing and finishing production, ensure workflow nodes call corresponding batch formulas and test data |
| Trigger rule | Trigger according to production cycle, support single vat, single batch, or per-shift triggering | Adapt to the data update frequency of this category per vat or batch, match actual production rhythms |
| Parameter verification node | Configure color difference ΔE threshold, dye vat temperature deviation range, and sewage discharge volume upper limit verification | Cover core parameter verification requirements for dyeing and finishing processes, intercept unqualified data in advance |
nodeId | Configure unique nodeId for data pulling, format conversion, and exception branches respectively | Facilitate workflow debugging and exception location, quickly locate the execution status of corresponding links |
| Exception branch configuration | Configure alert and rollback nodes for three scenarios: full vat scrapping, discharge exceeding standard, and parameter abnormality | Match severe consequences of errors in this category, trigger corresponding processing flows in a timely manner |
| Tool call delay threshold | 300–600 seconds | Adapt to upload delays for dye vat curves and color measurement data, avoid tool call timeouts |
Three common errors
- After calling the chart tool to generate a dye vat temperature curve, the question-and-answer interface returns an empty result. No rendering binding node for the image URL is configured in the workflow, only the original interface return value is returned without format conversion.
- A 400 error is returned when the tool node is selected to perform chemical mixing ratio verification. No format verification is performed on the input chemical parameters, and values that do not meet the units of dyeing and finishing processes are passed in, triggering interface parameter verification failure.
- After the AI dialogue node returns empty or an error, the workflow terminates directly without follow-up processing. No exception branch processing logic is configured, and no jump node is set for empty results or error scenarios.
How to confirm the configuration is complete
- Execute a simulated vat-level production workflow, check whether the variable binding of each node correctly matches the preset dye vat number and formula data.
- Trigger an abnormal parameter scenario, verify whether the exception branch jumps to the corresponding alert and processing node.
- Call the chart tool to generate a color difference value curve, confirm that the question-and-answer interface can normally render the generated image content.
- View the workflow log, confirm that the
nodeIdof each node is consistent with the configured unique identifier, with no duplicates or missing entries.
