What the data for this category looks like
The business data for power generation equipment manufacturing mainly comes from four categories: equipment factory parameter manuals, operation and maintenance inspection logs, fault maintenance records, and quality inspection reports. The data update rhythm adjusts with the launch of new models and quarterly inspection cycles, with no fixed daily update frequency. The structure of a single document includes fields such as equipment model, rated power, rotational speed, fault code, and maintenance steps. The unit of power is megawatt (MW), the unit of rotational speed is revolutions per minute (r/min), the fault code is a 6-digit digital code, and maintenance steps are presented in modules classified by fault level.
What constraints do these characteristics impose on the multi-turn dialogue and prompt engineering link
The structured data characteristics of power generation equipment manufacturing impose clear constraints on multi-turn dialogue and prompt configuration. Exclusive fields such as equipment model and fault code require multi-turn dialogue to retain business identifiers in the context to avoid retrieval confusion across devices. The fixed unit system requires the prompt to constrain the consistent use of standard units such as megawatts and revolutions per minute in conversations to prevent parameter matching deviations. The structure of documents divided by fault level requires multi-turn interactions to associate the currently discussed fault type to ensure that retrieved maintenance steps correspond to the correct scenario. The non-fixed update frequency requires the knowledge base to support incremental uploads of new model data to avoid calling outdated equipment parameters in conversations.
How to set the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum Context | 8000–12000 token | Matches the total length of a single chunk of power generation equipment documents to avoid context overflow |
messages | Retain the last 15 rounds of user and assistant interactions | Filter irrelevant logs and focus on business conversations related to power generation equipment |
| Query Optimization | Enabled, parameters calibrated via actual testing | Optimize retrieval queries for technical terms such as equipment models and fault codes |
variables | Bind equipment model and fault code fields | Accurately match exclusive knowledge base data for this category |
chatId | Bind session unique identifier | Maintain context consistency across multi-turn dialogues |
| Single Retrieval Limit | Top 10 recall results | Cover the number of maintenance documents for common faults in power generation equipment |
Three common misconfigurations
- Phenomenon: The knowledge base reference field returned after API calls is empty. Cause: The exclusive fields such as equipment model and fault code are not bound in
variables, causing retrieval to fail to match exclusive data for the power generation equipment category. - Phenomenon: Subsequent replies in multi-turn dialogue fail to carry over the equipment parameters mentioned in the previous round. Cause: The session unique identifier is not bound via
chatId, causing the context to be accidentally reset. - Phenomenon: Streaming output is interrupted midway, with status code 429 returned. Cause: The maximum context length is not restricted, causing the token limit for a single request to be exceeded and triggering platform rate limiting.
How to confirm the configuration is correct
- Initiate a test dialogue that includes specific equipment models and fault codes, and check whether the reply accurately references the maintenance steps of the corresponding document
- View the session log to confirm that
chatIdremains consistent across multi-turn interactions and that the context is not accidentally cleared - Test three consecutive rounds of dialogue, and check whether each round's reply carries over the equipment parameters or fault information from the previous round
- Enable streaming output testing, and confirm that reply content is returned segment by segment with no mid-interruption issues
