What the Data for This Category Looks Like
Core data for heat treatment scenarios comes from material grades, customer technical requirements, temperature control instruments, furnace temperature uniformity testing equipment, hardness testers, metallographic equipment, and production MES systems. Daily documents include heat treatment process cards, charging charts, furnace temperature curves, hardness and metallographic reports, equipment inspection forms, and exception handling sheets. Fields include heating temperature (unit: ℃), holding duration (unit: minutes), hardness value (unit: HV or HRC), charging position number, and others. Data updates occur per heat and per batch. The number of documents per batch varies with the scale of the heat.
What Constraints These Characteristics Bring to Workflow Orchestration
Multi-source heterogeneous data sources require workflows to support connecting different types of nodes, to interface with equipment data, business documents, and customer requirements respectively. Dynamically updated data per heat requires workflows to support batch-triggered execution, to avoid redundant checks on fixed cycles. Non-standard document field formats require workflows to support flexible binding of multi-field variables, to adapt to process requirements of different customers. The severity of error consequences requires workflows to configure branch processing and failure retry mechanisms, to prevent abnormal flows from proceeding to subsequent links.
Configuration Settings
The following are configuration instructions for FastGPT v4.17.0:
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Variable Reference Configuration | Bind multiple fields such as furnace temperature, holding duration, and hardness value from variables | Heat treatment documents require cross-verification of multi-dimensional parameters, and a single variable cannot cover all verification needs |
| Node Timeout Threshold | 600 seconds | Full verification of documents for a single heat must be controlled within a reasonable duration, to avoid occupying scheduling resources from production links |
| Branch Trigger Rule | Trigger the rollback process based on the result of the abnormal verification node marked by nodeId | Abnormal parameter values must trigger an immediate termination of the verification process for the current heat, to prevent incorrect flow progression |
| Maximum Retry Count | 2 times | Address temporary data fluctuations from equipment such as temperature control instruments and hardness testers, without excessive retries that delay production |
| Result Output Configuration | Only output a final verification report of 500–1000 characters | Hide execution logs from intermediate nodes, to align with business user habits of only needing final verification conclusions and avoiding redundant information interference |
Three Common Misconfigurations
- Phenomenon: Unable to stop the current debug mode when debugging a node, and the log returns a node ID matching failure. Cause: The corresponding relationship between the configured
nodeIdparameter and the actual execution node is not correctly configured. - Phenomenon: The variable reference dropdown menu only allows selecting a single variable, and cannot bind multi-field parameters. Cause: The multi-variable binding configuration for
variablesis not enabled. - Phenomenon: The workflow only calls a single model and cannot implement step-by-step processing. Cause: The execution link for series-connected multi-nodes is not configured, and only a single model node is bound.
How to Verify Correct Configuration
- Upload the full set of documents for a single heat, including heat treatment process cards and furnace temperature curves, trigger workflow execution, and check whether multi-dimensional verification nodes are automatically called.
- Open the variable binding panel, confirm that multiple fields such as furnace temperature, hardness, and process parameters can be selected at the same time.
- Simulate abnormal parameters, such as furnace temperature exceeding the set threshold, and confirm that the workflow triggers the branch rollback process.
- View the final output result, confirm that only the final verification report is displayed, with no redundant information from intermediate steps.
