What data for this category looks like
This category of data centers on the VIN master line for individual vehicles. Data comes from ERP/MES systems, VIN and vehicle configuration systems, tightening tool terminals, end-of-line (EOL) offline inspection lines, and quality traceability systems. Daily documents include production orders, VIN lists, assembly work instructions, tightening torque data, offline inspection reports, rework records, and consistency release documents. Teams update data via real-time synchronization per vehicle, real-time updates per workstation, and shift-level summary archiving. Core fields include VIN codes, workstation numbers, torque parameter values, inspection results, and rework identifiers. There are no uniform fixed units; values adjust based on parameter requirements for the corresponding business link.
What constraints these characteristics impose on workflow orchestration
The VIN master line characteristics of this category require workflows to bind VIN variables in variables to achieve precise matching of full-process data for individual vehicles, and avoid configuration mismatches during mixed-line production. Multi-source heterogeneous production data must be integrated by workstation or time sequence. Workflows need to configure multiple nodes for data pulling and format conversion. Real-time updated tightening data and offline inspection results require workflow nodes to support real-time data pulling, and cannot rely on static caching. Shift-archived rework records need to support batch query and association by shift, while adapting to field differences across different documents to avoid data parsing errors. Branch logic for work order generation and workstation jump must be triggered when torque anomalies or inspection failures occur.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind 3 variables: VIN code, workstation number, and qualified torque threshold, calibrated via actual measurement | Match corresponding production data around the individual vehicle VIN master line, avoid configuration confusion from mixed-line production |
nodeId | Assign unique nodeId to data pulling nodes and exception judgment nodes respectively, use integers in the range 1–100 | Facilitate precise positioning for workflow debugging and branch jumps |
| Global variable assignment | Assign the VIN code variable in variables via an API access link, use real-time pulled VIN code data | Adapt to real-time data update requirements per vehicle |
| Exception branch trigger | Trigger the maintenance node when torque data exceeds the threshold, set to trigger when torque deviation >5% | Comply with torque accuracy control requirements for vehicle final assembly |
| Workflow export | Export workflow configuration in JSON format, calibrated via actual measurement | Facilitate subsequent version management and cross-environment deployment |
This chapter's configurations are based on the workflow orchestration function of FastGPT v4.17.0.
Three common mistakes
- Phenomenon: After calling an API to trigger a workflow, the last returned reply content overlaps with the conversation results from the previous request. Cause: No context reset node is configured in the workflow, causing historical conversation data to be carried over to the current execution process.
- Phenomenon: The corresponding operation entry cannot be found when exporting workflow configuration. Cause: The export function is only available on the workflow release management page; it cannot be triggered when not switched to this page.
- Phenomenon: After assigning values to global variables via an API access link, the variables do not update. Cause: External assignment permission is not enabled in the
variablesconfiguration, causing API requests to fail to write to the corresponding variable fields.
How to confirm the configuration is complete
- Manually trigger the workflow, enter a test VIN code, and check whether the variables bound in
variablescorrectly load corresponding production data. - Simulate a scenario where torque data exceeds the threshold, and confirm whether the workflow jumps to the maintenance node and generates a corresponding work order.
- Call the API access link to pass test variable values, and check whether the node corresponding to
nodeIdcorrectly receives and updates the variables. - Export the workflow configuration file, and check whether the
variablesandnodeIdconfigurations included in it match the preset settings.
