What this category of data looks like
This category of data originates from engineering orders, sand, gravel, cement admixture inspection records, aggregate moisture content measurement data, mixing station control system logs, and project laboratory archive files. The data update rhythm follows per vehicle production batch, per raw material delivery batch, and daily summary. Daily documents include mix proportion notification, opening identification form, production and transportation order, raw material inspection report, test block molding record, and strength verification report. Data fields include mixing parameters, raw material batch number, test block curing duration, and pouring location identifier. Units include hour, cubic meter, batch number and other identifiers.
What constraints these characteristics impose on the "workflow orchestration" link
The high-frequency per-vehicle update requirement means the workflow must support millisecond-level triggering and parallel processing, to avoid single-node blocking affecting production rhythm. Multi-source heterogeneous data needs format unification within the workflow to adapt to differences in document structures exported by different systems. The daily aggregated batch data requirement means the workflow must support batch node calls, avoiding repeated configuration of single-data processing logic. The lag of test block strength reports requires the workflow to set delayed verification nodes to match the age verification cycle. The binding of raw material batches and production batches requires that variable association fields in the workflow must strictly correspond to raw material numbers and vehicle numbers, to avoid misalignment of traceability links.
How to set the configuration
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
variables | Bind three core identifiers: raw material batch number, vehicle number, and test block number | Match the update characteristics of per-vehicle and per-raw-material batches in this category, ensuring accurate traceability links |
| Trigger Condition | Trigger at three nodes: raw material delivery, production completion, and test block submission | Match the update rhythm of this category by process and batch, avoiding invalid triggers |
| File Upload Node Size Limit | 1000 MB | Adapt to the conventional file size of single raw material inspection reports and strength verification reports |
nodeId | Configure unique identifiers for the two core nodes of moisture content correction and strength verification | Facilitate node calling and exception location during workflow orchestration |
| Batch Processing Upper Limit | First 20 daily production batch data | Match the daily aggregated batch data processing requirements, avoiding node overload |
| Timeout Threshold | 600 seconds | Match the conventional processing duration of single reports in this category |
Three Common Errors
- Phenomenon: Failed to upload the mix proportion notification when calling the API to trigger the workflow, with the prompt Failed to create post presigned url. Cause: Failed to enable permission verification for the file upload node in the workflow configuration, or the storage path was configured incorrectly.
- Phenomenon: No test block strength verification result is returned after the workflow runs, and the field is empty. Cause: The test block number in
variableswas not correctly bound to the strength report query node, resulting in failure to match the corresponding data. - Phenomenon: Timeout error occurs when batch processing daily production data. Cause: The batch processing upper limit is set too high, exceeding the concurrent processing capacity of workflow nodes.
How to Confirm the Configuration is Correct
- Navigate to the workflow editing page, and verify that the
variablesconfiguration item has been bound to the raw material batch number, vehicle number, and test block number. - Simulate uploading a raw material inspection report, and confirm that the file upload node can normally receive and store the file without error prompts.
- Trigger the workflow run for a single production batch, and review the node log to confirm correct variable transfer and data matching results are displayed.
- Adjust the batch processing upper limit to 5, run the batch task, and confirm that the node can normally process the specified number of batch data.
