What the Data for This Category Looks Like
Daily data for precast concrete components is sourced from BIM detailed design, rebar and concrete batch ledgers, mold table and curing kiln operation records, laboratory test reports, and QR code traceability systems. Data updates occur per single component, per batch, or per kiln. Covered documents include component detailed drawings, rebar cutting lists, mold inspection records, pouring and vibration records, curing records, demolding and factory inspection reports, and other materials. Data fields include component number, rebar specification and usage volume, pouring time, curing kiln number, strength test values, and other metrics. Supported units include millimeters, cubic meters, hours, megapascals, and others.
Constraints on Workflow Orchestration
Multiple dispersed data sources require workflows to include input nodes connected to different systems, eliminating manual entry errors. High-frequency updates per single component, batch, or kiln require workflows to trigger on single production events, adapting to single-piece production processes. Multiple document formats require workflow file parsing nodes to support CAD, PDF, Excel, and other common formats. Strong correlations between fields require workflows to support passing associated parameters across nodes, ensuring data consistency across all verification links. Severe error consequences require workflows to include node verification and exception locating links, enabling quick troubleshooting.
How to Configure the Workflow
The following configurations are based on FastGPT v4.17.0, and are adapted to the inspection and process record review workflow requirements for precast concrete components.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Trigger Mode | Single component scan event | Precast concrete components generate data per piece or batch, so workflows must match single production processes |
variables | Bind component ID, rebar batch number, curing kiln number | Need to pass associated parameters from multiple data sources across workflow nodes |
| File Parsing Node | Support CAD, PDF, Excel formats, maximum 500 MB per file | Daily documents include multiple types such as detailed drawings and cutting lists; some detailed drawings have large file sizes |
| Timeout Setting | 600 seconds | Complex verification processes require sufficient processing time |
nodeId | Assign a unique identifier to each verification node | Quickly locate abnormal links when errors occur |
| Global Variable Storage | Retain component data from the last 24 hours | Matches the traceability period of production batches |
Three Common Misconfigurations
- Symptom: A workflow node cannot retrieve file link parameters when receiving files uploaded via a simple task. Cause: The upload component's output is not bound to the
variablesparameter transfer link, so parameters cannot pass across nodes. - Symptom: Downstream nodes read empty values after a global variable is modified. Cause: The updated variable state is not retained in the conversation context, so changes only take effect within a single node, and the updated variable is not written to global storage.
- Symptom: The temperature parameter cannot be set when calling the AI chat component. Cause: Custom parameter settings are not enabled in the large model configuration panel, or the parameter configuration entry under variable reference mode is not found.
How to Verify a Successful Configuration
- Trigger a simulated scan event, then confirm that each node executes in the preset order and generates verification results.
- Upload a PDF of a precast component detailed drawing, then confirm that the file parsing node correctly extracts core fields such as component number and rebar specification.
- Modify the test value of a global variable, then verify that downstream nodes can read the updated parameter content.
- Trigger an exception test scenario, check node logs, then confirm that the abnormal node identified by
nodeIdaccurately locates the error link.
