What the data for this category looks like
Lithium-ion cell manufacturing process data comes from raw material batch ledgers, production MES systems, slurry and coating testing equipment, workshop dew point monitoring systems, formation and grading cabinets, and laboratory testing equipment. Data updates occur in real time per batch and per individual cell. Daily documents include batching records, coating and rolling parameters, winding or lamination process records, liquid injection ledgers, formation and grading data, OCV and safety test reports. Data fields include slurry solid content, coating areal density, workshop dew point, formation and grading voltage, and others, all with clear industry standard units.
What constraints these characteristics impose on tool calling and plugin workflows
The real-time requirements for data in this category require tool calling to match production beat, to avoid outdated data caused by cache expiration. The structure of data associated with batches and individual cells requires tool calling to pass precise batch numbers or cell IDs as query parameters. Multiple heterogeneous data sources require tool calling to support integration with different types of device interfaces and databases. The high precision requirements of electrochemical systems require that results returned by tool calling undergo format validation, to avoid production abnormalities caused by incorrect parameters.
How to set configurations
These configurations are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API function-call configuration | Enabled | Adapts to the structured parameter calling requirements of lithium-ion cell manufacturing process data, ensuring the model accurately calls the corresponding interface |
| Tool call timeout | 30-60 seconds | Matches the data return cycle of formation and grading equipment, avoiding blocking the conversation flow due to excessive waiting time |
| Tool call cache strategy | Cache at batch granularity for 1-24 hours | Process data for cells in the same batch has no real-time changes, caching reduces repeated requests to production systems |
| Workflow/API tool selection | Force specified | Prevents the model from randomly calling irrelevant tools, ensuring only interfaces related to lithium-ion cell manufacturing process data are accessed |
| Tool parameter validation rules | Validate batch number and device ID formats | Ensures incoming query parameters comply with the standard format of cell manufacturing business, avoiding invalid calls |
Three common mistakes
- Symptom: A prompt indicates missing pre-authentication steps when calling tools, making it impossible to initiate process data queries. Cause: Pre-check requirements for business interfaces were not followed, and the identity verification interface was not called first to obtain access tokens.
- Symptom: JPG-format process drawings retrieved via HTTP tools cannot be displayed directly in conversations, only binary strings are returned. Cause: No format conversion steps were configured for tool return results, and the binary stream was not converted into a picture resource accessible via URL.
- Symptom: The number of results returned by tool calls does not match actual records, and cannot match all process records for cells in the same batch. Cause: The query range for tool calls was not restricted, resulting in too many irrelevant data being returned or some batch data being omitted.
How to confirm configurations are set correctly
- Initiate a process specification query with a known valid cell batch number, verify that tool calls can correctly retrieve batching, coating and other process parameters for the corresponding batch.
- Upload a JPG-format process drawing file, verify that the HTTP tool can return a renderable image link that can be displayed normally in the conversation interface.
- Simulate a query request with an invalid batch number, verify that the tool call returns a clear error prompt.
- Initiate multiple consecutive queries for process data of cells in the same batch, verify that the tool cache takes effect, avoiding repeated calls to production system interfaces.
