What the Data for This Category Looks Like
Ready-mixed concrete production data sources include engineering orders, sand, gravel, cement admixture inspection records, aggregate moisture content measurement data, mixing station control system logs, and project laboratory test block records. Data updates follow three rhythms: per vehicle production task, per batch of incoming raw materials, and daily laboratory testing. Daily documents include mix proportion notifications, opening identification forms, production and transport orders, raw material inspection reports, test block forming records, and strength test reports. Fields covered include cementitious material dosage, aggregate gradation, departure time, pouring location, and test block compressive strength values. There is no unified fixed global serial number; documents must be associated by task batch.
Constraints Imposed on Tool Calling and Plugins Workflow
Ready-mixed concrete production data has high update frequency and is tied to task batches. Tool calls must pull the latest aggregate moisture content and mix proportion parameters in real time to avoid batching errors caused by expired data. Differences in fields across multiple structured document types require plugins to adapt field extraction rules for different documents, ensuring retrieved content matches equipment inspection and maintenance needs. Errors directly impact project quality and progress. Tool calls must add parameter verification and result validation steps to prevent production issues from abnormal tool return data. Cross-departmental production, transportation, and laboratory data require plugin linkage via functionCall. Tool call response delay must be controlled within a reasonable range to avoid disrupting production scheduling.
Configuration Settings
All configurations below are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | Auto | Adapts to real-time updated production data and equipment fault scenarios, no need to manually specify tool type |
| Workflow/API function-call configuration | Batch call | Adapts to batch query requirements for multi-equipment inspection |
| Tool call trigger rule | Trigger by equipment number and fault keyword | Matches standard terminology for ready-mixed concrete equipment inspection, quickly locates corresponding maintenance documents |
| Tool call timeout | 300 seconds | Matches the average response time of mixing station control system and laboratory data retrieval |
| Knowledge base retrieval count | Top 6 entries | Covers valid information across multiple related documents including mix proportions, test block records, and raw material inspections |
| Context window size | 1000 token | Adapts to content processing requirements for multi-document association |
| Citation mark filtering | Enabled | Avoids serial number marks from knowledge base retrieval appearing in generated results |
Three Common Misconfigurations
- After a tool call terminates, the interface displays "Tool call failed" status code 400 with no fallback response. Cause: No fallback logic is configured for tool call failures, the conversation flow is interrupted directly, and the setup does not adapt to emergency maintenance needs for ready-mixed concrete production.
- Generated results include the phrase "Citation Mark: [1]". Cause: Citation mark filtering configuration is not enabled, and serial number marks from knowledge base retrieved documents are directly included in generated text, which violates equipment inspection report output specifications.
- Custom interface replies are not triggered after a user inputs a specified equipment fault keyword. Cause: Keyword interception rules are not configured correctly, and call parameters for the custom interface are not bound, so the system uses built-in knowledge base reply content instead.
How to Verify Proper Configuration
- Input an inspection question that includes a mixing station equipment number, confirm the system automatically calls the corresponding maintenance document tool and returns structured maintenance steps.
- Input a question that includes a fault description, check that the generated result does not contain phrases like "Citation Mark: [1]", and only retains maintenance suggestions and document association content.
- Input preset interception keywords, confirm the system jumps to the bound custom interface and returns corresponding maintenance guidance content.
- Simulate inputting inspection questions for three different devices consecutively, confirm the tool call timeout configuration does not trigger frequent timeout errors.
