What the data for this category looks like
Data for this category comes from customer color swatches, formula libraries, dye chemical batches, dye vat control systems, colorimeters, setting machines, and environmental monitoring equipment. Daily generated documents include dyeing formulas, chemical weighing records, dye vat curves, proofing confirmation sheets, color difference reports, setting process sheets, and sewage ledgers. Data updates occur per vat, per batch, or per shift. Dyeing formulas include numeric fields such as dye ratios and additive dosage. Dye vat curves record temperature and pressure parameters per minute. Sewage ledgers record discharge concentration and duration. Fields and units align with process requirements for wet chemical processing.
What constraints these characteristics impose on the "workflow orchestration" link
Workflows must trigger based on production nodes to avoid redundant execution, due to high-frequency batch data updates. Workflows must uniformly parse structured data exported by instruments and manually filled document scans, to handle multi-source heterogeneous data formats. Cross-verification of dye vat curves and color difference reports requires real-time pulling of associated data for the corresponding batch. Delayed processing is not suitable for this task. Batch correlation in wet chemical processing requires workflows to bind to the batch dimensions of dye vats and dye chemicals, to avoid mixing data across batches. Compliance verification of environmental monitoring data requires real-time comparison with production documents, to ensure data synchronization.
How to set up the configuration
This configuration is based on FastGPT v4.17.0, and adapts to workflow orchestration needs for dyeing and finishing scenarios.
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
| Global Variables | Bind dye vat batch number, dye chemical batch number | Match the correlation dimension of business data, configure corresponding fields via the variables parameter |
| Database Connection Node | Fill in the corresponding port number, calibrate based on actual measurements | Adapt to the exclusive port configuration of the dye vat control system |
| File Upload Node | Allow uploading JPG/PNG format files, single file limit 100 MB | Adapt to the file type and size limits for color swatches and color difference reports |
| Tool Call Node | Select qwen3.5-plus model, first 3 concurrent request limit | Reduce the probability of request limit exceeded errors |
| Node Timeout Setting | 600 seconds | Adapt to the pulling time of dye vat curves and cross-document comparison |
| Node ID Configuration | Bind the nodeId of the corresponding database and tool call nodes | Ensure correct execution order and association relationship of workflow nodes |
| Workflow Trigger Rule | Trigger based on per-shift or per-batch production tasks | Match the data update frequency and production rhythm |
Three Common Mistakes
- The database connection node cannot accept port number input. The symptom is that the interface port input box is grayed out or unresponsive. The cause is that the port parameter is not pre-configured in
variables, or the data source bound to the node does not have port access permissions enabled. - The tool call node frequently returns a 429 status code. The symptom is that the log shows Request rate increased too quickly. The cause is that the number of concurrent requests exceeds the model's current limit threshold, and a reasonable concurrency upper limit is not set.
- The workflow cannot trigger the file upload function. The symptom is that the upload button is not displayed or there is no response after uploading. The cause is that the node's file upload permission configuration is not enabled, or the allowed upload file types do not include the image format required for testing.
How to Confirm the Configuration is Complete
- Test the database connection node, check whether the returned dye vat data includes the preset batch association fields, and confirm that the
variablesparameter configuration takes effect. - Trigger the file upload node, upload a test color swatch image, and confirm that the node can normally receive and parse the file content.
- Simulate a single-batch production task to trigger the workflow, check the request log of the tool call node, and confirm that no 429 error occurs.
- Check the binding value of the global variables, and confirm that it matches the dye chemical and dye vat parameters of the current production batch.
