What Data for This Category Looks Like
Power generation equipment manufacturing declaration materials and file data originate from internal enterprise project initiation declaration documents, special equipment inspection archives, manufacturing process compliance documents, and industry standard reference materials. Data is updated in batches when individual project initiation starts. Daily compliance files are updated monthly. Most documents are structured PDFs or Word files. Individual materials range from thousands to tens of thousands of characters per document, including fields such as equipment model, rated power, manufacturing date, and inspection number. Units mostly use industry standard measurement methods such as MW, hours, pieces.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
The characteristics of declaration materials and files for power generation equipment manufacturing impose multiple constraints on multi-turn dialogue and prompt engineering workflows. The wide range of individual document lengths easily causes context overflow, so the context capacity of single-turn dialogue must be limited. Professional fields and industry-specific units require targeted verification rules built into prompt engineering to ensure accurate parameter matching. Data updates follow project progress rhythms, so multi-turn dialogue must distinguish the project cycle associated with the current session to avoid referencing expired compliance information. When reviewing multiple associated files, the messages parameter must be used to pass context in dialogue order to avoid confusing material content from different projects.
How to Configure the System
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context | 8000–12000 characters | Adapts to the context processing limit of FastGPT v4.17.0, while matching the span of individual declaration material lengths for power generation equipment to avoid context overflow |
| Question Optimization | Enabled | There are many power generation-specific technical terms, and enabling this function improves the accuracy of understanding professional expressions |
chatId | Generate a unique identifier per project session | Distinguishes review sessions for different power generation equipment projects to avoid material confusion |
messages | Pass the first 10 historical messages in dialogue order | Controls the total context volume while retaining sufficient review context information |
variables | Bind project-specific compliance field variables | Quickly calls information such as equipment parameters and inspection numbers corresponding to the project |
| Single Search Limit | Top 6 retrieval results | Adapts to the association density of file materials to avoid interference from irrelevant information on review judgments |
Three Common Misconfigurations
- Issue: The dialogue deletion interface returns a 500 status code, and historical session records cannot be cleared. Cause: The
chatIdparameter is not correctly carried, so the system cannot match the session data of the target review project. - Issue: After uploading a power generation equipment declaration file, parsing fails with the prompt "Unsupported format". Cause: The document chunk length is not adjusted to fit the long material structure, exceeding the system's default single-chunk character limit.
- Issue: After enabling the question optimization function, the dialogue does not generate supplementary review prompts. Cause: Project-specific
variablesare not bound, so prompt engineering cannot call exclusive information such as equipment parameters, and cannot generate targeted questions.
How to Confirm the Configuration Is Correct
- Initiate a single-turn test dialogue, input "Verify the declaration materials of XX model steam turbine", check whether the returned content is associated with project-specific equipment parameters to confirm that the
variablesbinding takes effect. - Initiate a cross-project test, switch the
chatIdand input the same review question, check whether the returned content corresponds to the new project data to confirm that the session identifier management takes effect. - Upload a long document declaration material, check the number of parsed chunks to confirm that the maximum context setting adapts to the material length and avoids overflow.
- Call the dialogue deletion interface with the correct
chatIdparameter, check that the interface returns a 200 status code to confirm that the session deletion function works properly.
