What this category's data looks like
Data for this category covers dyeing, setting, quality inspection, and environmental protection links. Sources include customer color samples, formula libraries, dye chemical batch records, dye vat control systems, colorimeters, setting machine equipment, and environmental monitoring devices. Daily generated documents include dyeing formulas, chemical weighing ledgers, dye vat operation curves, proofing confirmation sheets, color difference test reports, setting process sheets, and sewage discharge ledgers. Data updates follow cycles per vat, batch, or shift. Each record includes fields such as batch number, process parameters, test results, and emission indicators, covering standard units commonly used in processing and testing such as temperature, concentration, time, and weight.
What constraints do these characteristics impose on workflow orchestration
The multi-source heterogeneous data and high-frequency batched update characteristics of this category require the workflow to support parallel pulling of data sources from different devices and systems. The update cycle based on vats and shifts requires the workflow to trigger execution per single batch to avoid invalid repeated calculations. Documents include structured process parameters and semi-structured test reports, requiring the workflow to support field mapping and format conversion between nodes. Compliance requirements for environmental monitoring data require built-in validation links in the workflow to perform legality checks on data such as sewage ledgers. Process correction needs for scaling from lab-scale to production require the workflow to link with the formula library and proofing data to achieve automatic iterative adaptation of parameters.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
variables | Define custom variables such as batch number, dye chemical batch, and test thresholds, with a value range of 600–1200 characters | This category's data uses vat and shift as independent units. Custom variables can bind parameters exclusive to a single batch, avoiding data confusion across batches |
| Trigger Node Settings | Trigger based on the completion time of device-reported data | Data updates follow vat or shift cycles. Triggering after device reports ensures the integrity of data for a single batch |
nodeId | Assign unique identifiers to nodes for dye vat data pulling, color difference report parsing, and ledger summary | When orchestrating multiple parallel nodes, you can precisely control node execution order and data flow paths |
| Node Timeout Threshold | 300–600 seconds | Pulling dye vat curve and colorimeter data takes a certain amount of time. This threshold covers the maximum time required for device data upload |
| Data Validation Configuration | Add required field checks for batch number, process parameters, and emission values | Abnormal data in this category can lead to rework or scrapping of entire vats. Validation can intercept invalid data in advance |
| FastGPT Version | FastGPT v4.17.0 | This version supports multi-node parallel orchestration and custom variable binding, adapting to the batched data processing needs of this category |
Three Common Mistakes
- When configuring HTTP request nodes in the workflow, failing to inject custom variables into request parameters, resulting in dye vat data pulled that does not match the current vat, leading to data misalignment or empty request results. This occurs because parameters such as batch number and dye chemical batch in
variablesare not bound according to batched requirements, making it impossible to accurately pull data for a single batch. - When orchestrating multiple nodes, failing to configure unique identifiers for
nodeId, leading to disordered node execution order and missing or duplicated ledger summary data. This occurs because dependencies between nodes are not clearly defined, and the system cannot transfer data as expected. - When upgrading FastGPT, failing to correctly modify the compose file to add corresponding environment variables, resulting in the
variablesconfiguration of the workflow not taking effect. This occurs because the official configuration documentation is not referenced to update the deployment file, and environment parameters required for batched processing are omitted.
How to Confirm Proper Configuration
- Submit test data for a single vat, check whether the workflow automatically pulls data such as dye vat curves and color difference reports for the corresponding batch, and confirm that the trigger node and variable binding take effect.
- View node logs to confirm that nodes corresponding to each
nodeIdexecute in the expected order, with no execution timeouts or error messages. - Simulate abnormal data uploads, check whether the data validation link intercepts invalid fields, and confirm that the validation configuration takes effect.
- Export the generated production ledger report, confirm that the report includes all required document content such as dyeing formulas and sewage ledgers for this category.
