What the data for this category looks like
Data for this category comes from steel coil labels and quality certificates, press and feeder operation data, mold management systems, MES systems, and coordinate measuring machine or fixture inspection results. Daily generated documents include stamping work instructions, material utilization rate sheets, mold inspection sheets, first and last piece records, dimensional inspection reports, and mold change records. Data updates trigger per coil of material, per production batch, and each mold change. Document fields include material grade, thickness, press parameters, mold number, dimensional deviation values from inspections, and match corresponding measurement standards based on document type.
What constraints these characteristics impose on workflow orchestration
Because data updates per coil, batch, and mold change, workflows must support binding corresponding data sources to trigger conditions. This prevents cross-batch data mixing that causes batch dimensional deviations. Differences in fields across multiple document types require workflows to support parsing by type. Preset extraction rules for different documents prevent field matching errors. Real-time data from presses and fixtures must be synced in. Workflows must configure short-cycle data pull nodes to ensure ledger timeliness. Lagging data must not interfere with mold or press operation and maintenance judgments. Mold change records are closely linked to first and last piece data. Workflows must set dependency relationships between nodes. This ensures data after a mold change syncs to the corresponding ledger, preventing rework from assembly gap excesses. Differences in inspection report formats require workflows to support custom field mapping rules. This adapts to aggregation logic for multi-source heterogeneous data.
How to set configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Trigger Condition Settings | Bind coil batches, mold change events, or poll every 30 minutes | Matches the rhythm of data updates per coil, batch, and mold change |
variables Configuration | Include material grade, press operation parameters, dimensional deviation values from inspections | Covers core ledger extraction fields |
| Single Data Pull Timeout | 600 seconds | Adapts to pull delays for real-time press and fixture data |
| Node Dependency Rules | Set sequence based on data generation timing | Prevents cross-batch data mixing |
nodeId Configuration | Assign a unique identifier to each data source | Differentiates sources of multi-source heterogeneous data |
| Custom Field Mapping | Calibrate based on actual measurements | Adapts to document format differences across enterprises |
Three Common Errors
- Text classification extraction nodes return empty results. The cause is failure to configure field mapping for
variablesby document type. This prevents matching exclusive fields for stamping work instructions and inspection reports. - Workflow application import fails. The cause is failure to confirm FastGPT version compatibility. After upgrading the open-source version, check version adaptability of node configurations.
- Basic chart axis variable references are incorrect. The cause is failure to bind the data source corresponding to
nodeId. This causes the x or y axis to fail to obtain stamping parameter data for the corresponding batch.
How to confirm proper configuration
- Manually trigger a workflow for a coil batch. Check if extracted fields include the preset
variablescontent. - View the
nodeIdidentifiers of each data source node. Confirm there are no duplicate or missing identifiers. - Simulate a mold change event to trigger the workflow. Check if nodes execute in the correct sequence based on dependencies.
- Export the generated ledger report. Verify that it includes data such as material utilization rate and inspection deviation for the corresponding batch.
