What the Data for This Category Looks Like
Complete vehicle final assembly scenario data uses VIN codes as the core thread. Data sources cover ERP/MES systems, VIN and configuration systems, tightening tools, EOL inspection lines, and quality traceability systems. Daily documents include production orders, VIN lists, assembly work instructions, tightening data, offline inspection reports, rework records, and consistency release documents. Data is generated in real time for each vehicle, and summarized and archived per shift. Fields include 17-digit VIN codes, torque values (unit: newton meter), inspection item numbers, supplier batch numbers, and others. The structure changes with the complexity of vehicle configuration.
Constraints Imposed on Tool Calling and Plugins by These Characteristics
The use of VIN as the core retrieval key requires that tool calls bind VIN as a required parameter to prevent data matching errors. Multiple dispersed data sources require plugins to support simultaneous calls to multiple external interfaces to pull different types of inspection and configuration data. High-frequency real-time update requirements require tool calls to set reasonable timeout thresholds to avoid blocking production beats. Complex document structures require plugins to support filtering returned data by priority to reduce invalid information occupying context space.
Configuration Settings
This page is written based on FastGPT v4.17.0. The following are reference configurations for tool calling and plugins:
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Workflow/API tool selection | auto | Adapts to the need for parallel plugin calls in final assembly inspection scenarios, automatically assigns call priority |
| Workflow/API function-call configuration | Enabled | Supports calling external interfaces to obtain VIN configuration, tightening data, and offline inspection results |
| Plugin timeout period | 5-10 seconds | Matches the production beat of complete vehicle final assembly, avoids blocking station processes due to interface waiting |
| Number of returned entries per single plugin call | Top 6 entries | A single VIN is associated with dozens of core inspection items, prioritize pulling the most critical inspection and configuration data |
| Plugin result cache duration | 30 minutes | Matches the configuration consistency of vehicles in the same production batch, reduces repeated interface calls |
Three Common Mistakes
- Phenomenon: A
Failed to fetcherror is returned when calling the VIN matching interface. Cause: Cross-domain access permissions for the plugin are not configured, or the interface timeout period is set too short to complete data pulling within the production beat. - Phenomenon: The tightening data field returned by the plugin is empty. Cause: VIN is not set as a required parameter for interface calls, causing the interface to fail to match the real-time tightening records of the corresponding vehicle.
- Phenomenon: No output file is obtained after calling the plugin that generates inspection reports. Cause: The file storage path for the plugin is not configured, or no format processing step for file return is added in the tool calling link.
How to Verify Correct Configuration
- Enter a test VIN code, trigger plugin calls, and check whether the returned configuration data matches the content of the corresponding assembly work instruction.
- Simulate uploading real-time tightening data, call the corresponding plugin, and check whether the torque value returned by the interface complies with preset qualified judgment rules.
- Trigger a batch plugin call test, and check whether the timeout period and number of returned entries meet the preset configuration.
- Simulate an abnormal interface response, and check whether the system triggers preset failure retry or alert logic.
