What Data for This Category Looks Like
Precast concrete component data comes from BIM detailed design, rebar and concrete batch ledgers, mold table and curing kiln operation logs, laboratory test reports, and component QR code traceability tags. Daily documents include component detailed drawings, rebar cutting lists, mold inspection records, pouring and vibration records, curing cycle records, and demolding and factory inspection reports.
Data is updated per individual component, per batch of materials, and per curing kiln batch. Core fields include component ID, rebar specification, concrete strength grade, curing duration, and inspection pass flag, among others.
Constraints Imposed by These Characteristics on Workflow Orchestration
Since data is updated frequently at multiple granularities (individual component, per material batch, per curing kiln batch), workflows must support triggering execution at different granularities.
Core documents include heterogeneous format files such as engineering detailed drawings and rebar cutting lists. Workflows must be configured with multi-source heterogeneous data reading nodes.
Precast concrete components correspond one-to-one with on-site lifting positions. The traceability link must bind the component’s unique QR code identifier to on-site installation records, so workflows must preset associated verification logic.
Errors can lead to component scrapping and project delay. Workflows must include an automatic alert link for abnormal results.
Configuration Settings
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Knowledge Base Selection | Store component detailed drawings, rebar batch ledgers, and curing records in separate databases by data type | Retrieval logic varies across data types; separating databases optimizes retrieval matching efficiency |
variables | Preset component ID and curing kiln ID as global variables | Covers high-frequency retrieval fields for individual components and per-kiln batches, simplifying subsequent node call logic |
| Tool Call Configuration | Set nodeId to the component ID node when calling the BIM parsing tool | Binds the unique component identifier to ensure parsed results are accurately associated with the corresponding component |
| Exception Handling Node | Set timeout threshold to 300 seconds, retry count to 2 times, cache duration to 24 hours | Precast concrete component data parsing requires reading multi-source heterogeneous files; this value is calibrated based on actual business scenario testing |
| Execution Trigger Condition | Trigger the workflow by newly generated component QR codes | Matches the update frequency of data updated per individual component, ensuring the traceability process starts promptly |
| Result Verification Rule | Verify embedded position matching items between the rebar cutting list and detailed drawing | Prevents quality issues where embedded parts are misaligned and cannot be installed on-site |
Three Common Misconfigurations
- Phenomenon: Global variables are not assigned correctly after workflow execution, and retrieval results are empty. Cause: The component ID field parsed from the QR code is not bound in the
variablesconfiguration, so the variable does not receive valid values. - Phenomenon: The tool call node returns status code 400, with a prompt about missing parameters. Cause: The
nodeIdassociated with the component’s unique identifier is not set in the tool call configuration, so the tool cannot retrieve corresponding business data. - Phenomenon: Two thinking process outputs appear during workflow debugging. Cause: The tool call node is not configured with a fixed return format, so the system automatically triggers the intent recognition process twice.
How to Verify Correct Configuration
- Upload a precast concrete component detailed drawing and rebar cutting list, trigger workflow execution, and confirm that global variables correctly extract the component ID and rebar specification.
- View the tool call log to confirm that
nodeIdis bound to the unique identifier of the corresponding component, with no missing parameter error messages. - Simulate an abnormal scenario, such as modifying the strength grade in the curing record, and confirm that the workflow triggers the abnormal alert link.
- Check the knowledge base separate database configuration to confirm that different types of business files are stored in the corresponding directories, and can be accurately matched during retrieval.
