What the data for this category looks like
Refinery and chemical production service inquiry data mainly comes from DCS real-time control systems, equipment management EAM systems, process specification libraries, and laboratory analysis systems. Real-time operating condition data updates every second. Equipment ledgers and process specifications are synchronized and revised every 7 days for batch updates. Material batch data is bound with production dates and quality inspection numbers. The data includes process parameters (units: MPa, ℃, t/h), equipment ID codes, and patrol inspection record fields. Structured data is stored in relational tables, while unstructured process documents are saved as chapterized PDF files.
What constraints these characteristics impose on tool calling and plugins
The data characteristics of refinery and chemical production impose multiple constraints on tool calling and plugins. The second-level update of real-time operating condition data requires that tool calling response delay does not exceed 5 seconds, otherwise it cannot support real-time service inquiries. Formatted exclusive fields such as equipment IDs and material batch numbers require that plug-in calls strictly match coding rules, otherwise accurate results cannot be returned. Chapterized unstructured process documents require plug-ins to specify document fragment indexes to locate target content. For scenarios of multi-source data mixed queries, plug-ins need to connect to DCS, EAM and other systems at the same time, and cross-source data permission verification logic must be configured.
How to set up the configuration
The following configuration methods apply to FastGPT v4.17.0, and use the functionCall and toolChoice parameters supported by the platform.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Tool call timeout | 300 seconds | Matches the query delay requirements of real-time refinery and chemical production data, avoids inquiry interruptions caused by long waiting times |
functionCall | Enabled, specify the function list as "Query real-time operating conditions, Query equipment ledger, Query process specifications" | Adapts to the three core service inquiry scenarios of refinery and chemical production, restricts the AI to only call preset tools |
| Database plugin character encoding | UTF-8 | Resolves Chinese data display abnormalities, matches the Chinese field format of refinery and chemical production data |
| Workflow branch execution logic | Only execute AI reply branch | Avoids information redundancy caused by simultaneous output of tool call results and AI replies |
toolChoice | auto | Allows AI to independently select appropriate tools based on user questions, adapts to complex service inquiry scenarios |
| Qwen2.5 tool call switch | Enabled | Adapts to the function calling capabilities of the Qwen2.5 model, supports multi-tool linkage in refinery and chemical production scenarios |
Three common misconfigurations
- Phenomenon: The AI return content from the first layer of tool calls in the workflow is printed and cannot be hidden via the interface. Cause: No output filtering rules for workflow branches are configured, causing tool return content from intermediate steps to be forcibly displayed.
- Phenomenon: The tool call module triggers both AI reply generation and next-level branch execution, resulting in information redundancy. Cause: The parallel execution logic of the workflow does not have branch isolation, and only a single path is not specified for execution.
- Phenomenon: The MySQL database plugin cannot display Chinese data, and no issue is resolved after all configuration adjustments. Cause: The character encoding of the database plugin is not configured as UTF-8, causing encoding conversion errors during data transmission.
How to confirm the configuration is complete
- Initiate a test inquiry for real-time operating condition queries, check whether the tool call response time meets the preset timeout requirements.
- Trigger the tool call flow, confirm that only one of the AI final reply or tool call result is displayed, with no redundant output.
- Call the database plugin to query refinery and chemical material data containing Chinese, confirm that Chinese content is displayed normally.
- After enabling the Qwen2.5 tool call switch, initiate an inquiry that requires multi-tool linkage, confirm that the AI correctly selects and calls preset tools.
