What the data for this category looks like
This category of data covers core business outputs of flow, pressure, temperature, and analytical instrument manufacturers and metrology laboratories. Daily documents include assembly and commissioning sheets, calibration procedures, original calibration records, error curves, metrology certificates, and software version logs. Data is sourced from design documents, standard instrument monitoring data, calibration software outputs, laboratory information systems, and customer range requirements, and is updated once per device per calibration. Document fields include tested part number, standard instrument parameters, ambient temperature and humidity, error calculation values, traceability chain number, and others. Units include metrology-related standard units such as pascals, degrees Celsius, milliliters per minute, and more.
What constraints these characteristics impose on workflow orchestration
The single-device, single-update nature of data in this category requires workflows to bind unique device identifiers and calibration batches to avoid cross-device data confusion. Scenarios involving mixed processing of multiple types of metrology documents require workflows to support automatically triggering corresponding processing nodes based on document type. The need to validate highly compliant fields such as traceability chain numbers and standard instrument parameters requires workflows to include built-in automated compliance checks. Fixed format requirements for metrology-related units require mandatory matching of statutory metrology standard units during text concatenation. Input format differences caused by scattered data sources require workflows to include format standardization processing steps.
Configuration Setup
This configuration is based on the workflow node functionality of FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Text concatenation node | Enable variables binding mode, concatenate in the order of calibration document fields | Ensure the order of metrology fields aligns with traceability requirements, avoid format confusion |
| AI question answering node | Bind nodeId to the ID of the original data processing node | Enable streaming output of calibration results, match the real-time generation requirement for exception reports |
| Retry strategy | Retry 2 times after failure, interval 60 seconds | Address temporary unresponsive calibration software scenarios, ensure process stability |
| Workflow timeout setting | Set to 300 seconds | Address time-consuming steps for multi-point error collection, avoid process interruption |
| Variable mapping rule | Only map three types of fields: tested part number, error value, and metrology certificate number | Filter non-essential data, comply with document compliance requirements |
| Streaming output setting | Enable segment-by-segment return mode, each segment is 800 characters | Adapt to the segmented reading and editing requirements for exception reports |
Three Common Configuration Errors
- Issue: The AI question answering node cannot receive output from the text concatenation node, while the text concatenation node can output complete content normally. Cause: The
variablesbinding mode was not enabled in the text concatenation node, causing the output format to not meet the input requirements of the AI question answering node. - Issue: When calling a workflow via API, variables in the text concatenation step do not return normally, while concatenation results are normal during local debugging. Cause: The variable pass-through switch was not enabled in the workflow configuration, causing the bound
variablesparameter to not be passed during API calls. - Issue: The front-end page is unresponsive when calling workflows concurrently, while system resources and Docker container load do not exceed thresholds. Cause: No reasonable concurrency limit was set for the workflow, causing a large number of requests to trigger calibration data processing nodes simultaneously and exceed the node processing limit.
How to Verify Successful Configuration
- Manually trigger the calibration workflow for a single device, check if the output of the text concatenation node is arranged in the order of calibration document fields.
- Call the API to initiate a workflow request, verify that all mapped metrology field content is included in the returned results.
- Simulate the scenario where calibration software is temporarily unresponsive, check if the workflow automatically retries according to the configured retry strategy.
- Enable streaming output testing, confirm that results are returned segment by segment in segment mode, with no format confusion issues.
