What data for this category looks like
Coating and painting scenario data covers multiple types of business documents and real-time collected data. Sources include coating supplier TDS/SDS, spray booth and oven operating data, colorimeter and film thickness gauge test results, environmental VOCs monitoring data, and workshop MES systems. Daily documents include coating process cards, coating batch lists, paint mixing records, film thickness and color difference reports, oven curves, defect repair orders, and VOCs ledgers. Data updates align with each coating batch, each shift production cycle, and continuous real-time collection. Fields include professional parameters such as film thickness (μm), color difference ΔE, oven temperature (℃), and VOC concentration (mg/m³).
What constraints these characteristics impose on tool calling and plugins
The data structure for this category is complex and tightly linked. Real-time collected device data and batch documents require precise matching. Therefore, tool calling must support multi-source data joint retrieval. Field definitions vary across different documents. Tool calling must be used to specify target extraction fields to avoid model confusion of parameter units. Errors directly affect product appearance and compliance. Tool calling must configure failure retry and exception alert mechanisms. In addition, curing curves and color adjustment parameters for coating processes must be verified against real-time device data. Tool calling must first bind the latest data within the production window, excluding expired batch records.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | auto | Supports automatic tool calling for multiple types of coating business documents, no need to manually specify a single scenario, covers process cards, test reports and other document types |
| Workflow/API function-call configuration | Extract film thickness, oven temperature, color difference ΔE, VOC concentration | Accurately extracts core parameters for coating processes and quality inspections, prevents the model from outputting irrelevant content, and ensures responses comply with coating professional standards |
| Timeout period | 60 seconds | Matches the collection interval of coating workshop device data, avoids excessive waiting that blocks production processes |
| Retry count | 3 times | Addresses common abnormal scenarios such as network fluctuations or temporary device disconnections, reduces invalid call attempts |
| Retrieval limit | Top 8 entries | Balances information completeness and context length, adapts to multi-link associated parameters of coating processes, avoids context overflow |
| Document chunk length | 800–1200 characters | Adapts to the paragraph structure of coating process cards, avoids splitting critical parameter combinations, and ensures the model can fully read process steps |
Three Common Mistakes
- Scheduled interface calls continuously trigger without valid output: The cause is that document update or device data trigger conditions are not bound, only a fixed timer is configured, resulting in calls returning empty data or expired batch information.
- Calls to large language models fail to meet expected effects: The cause is that core field extraction for coating scenarios is not specified via
functionCall, so the model does not prioritize reference to professional parameters from process cards and test reports. - Smart agent API calls fail when uploading files: The cause is that file upload permissions are not enabled in tool configuration, or supported coating-related file formats are not specified.
How to Confirm Configuration is Complete
- Check whether the
toolChoiceconfiguration item is set toautoor specifies thefunctionCallmode, confirm that the tool calling logic has taken effect. - Upload a coating process card and film thickness report to trigger tool calling, verify whether the returned results include core parameters such as film thickness and oven temperature.
- Simulate a network anomaly to trigger a call failure, check whether the preset retry mechanism and alert prompts are triggered.
- Confirm that FastGPT v4.17.0 is currently in use, ensure compatibility between plugin functions and configuration logic.
