What Data for This Category Looks Like
Data for this category originates from slab or billet batches, heating furnaces, mill automation control systems, online thickness and width measuring equipment, surface inspection devices, and manufacturing execution systems (MES). The update cadence is one update per coil or per individual steel billet; some online inspection data is updated in real time. Daily documents include rolling plans, heating schedules, rolling specifications, plate shape and thickness records, surface quality reports, and quality certificates. Fields include batch number, coil number, thickness (unit: millimeters), rolling speed (unit: meters per second), defect type, and other relevant items.
Constraints Imposed on Tool Calling and Plugins Workflow
This category uses continuous plastic deformation to control geometry and microstructure, with prominent coil-level traceability features. Tool calling must support associative retrieval of multi-source equipment data using batch IDs to avoid mixing data across coils. Structural differences between multiple types of process and inspection documents require tool calling to adapt to format parsing for different fields, ensuring parameter accuracy in maintenance Q&A. The combination of limited per-coil data volume and frequent updates requires tool calling to prioritize pulling real-time updated online inspection and MES data, without relying on static caching. Severe potential error consequences require tool calling to add a parameter verification step to prevent incorrect matching of equipment data caused by erroneous calls.
Configuration Settings
This document is based on FastGPT v4.17.0 configuration rules, with specific configuration items as follows:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | auto | Automatically match the corresponding equipment data retrieval tool based on inspection questions, adapting to real-time updated rolling and finishing equipment parameters |
| Workflow/API function-call configuration | Calibrated based on actual measurements | Some complex maintenance issues require mandatory calls to specified tools, which can be adjusted per actual scenarios |
| Maximum number of tool calls per run | Top 3 entries | The number of associated data entries per coil or individual steel billet is limited; excessive calls increase response latency |
| Tool call timeout period | 600 seconds | Equipment data retrieval involves multi-source MES and online inspection data, requiring sufficient time to complete cross-source calls |
| Context window size | 8000–12000 token | Carry context information from multiple documents such as rolling plans and heating schedules, ensuring coherent Q&A logic |
| Tool call data preprocessing | Enabled | Process retrieved data such as plate shape and thickness records to escape special characters, avoiding format errors |
Three Common Misconfigurations
- Phenomenon: Tool calls return an Invalid JSON error containing control character errors. Cause: The tool call data preprocessing switch is not enabled, and unescaped line breaks or tabs exist in retrieved plate shape and thickness records, which are directly passed to tool call parameters.
- Phenomenon: Responses are empty after configuring an online search tool. Cause: Equipment maintenance issues for rolling and finishing mostly rely on internal process and inspection data, and no internal equipment knowledge base association is configured, resulting in no matching search results.
- Phenomenon: Tool call node execution times out. Cause: The timeout period is not adjusted per multi-source data retrieval requirements; the default duration is insufficient to complete data pulling across MES and online inspection systems.
How to Verify Correct Configuration
- Submit an inspection question about surface defects of hot-rolled coils, and check whether the corresponding equipment data retrieval action is automatically matched in the tool call log.
- Trigger a maintenance Q&A request, and confirm that the returned results include associated content from category-specific documents such as rolling specifications and heating schedules.
- Simulate input containing unescaped characters, and check whether the tool call triggers the data preprocessing link without format errors.
- View tool call time consumption statistics, and confirm that it does not exceed the preset timeout threshold.
