What the Data for This Category Looks Like
Precast concrete component data comes from BIM or detailed design documents, rebar and concrete batch ledgers, mold table and curing kiln operation logs, laboratory test reports, and component QR code traceability data. Update frequency follows per single component, per batch, or per kiln. Covered documents include component detailed drawings, rebar cutting lists, mold inspection records, pouring and vibration records, curing records, and demolding and factory inspection reports. Fields include component number, rebar specification and length, concrete strength grade, curing duration, demolding strength value, and more. Units include millimeters, cubic meters, megapascals, hours, and others.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
Data sources for this category are scattered, and update rhythms differ across sources. Multi-turn dialogue must trigger targeted data pulls based on the update nodes of each data source to avoid mixing expired records into the context. Document structures include multiple types of professional forms, so prompts must adapt to the field rules of each document type. For example, the rebar specification on a rebar cutting list and the embedded part position on a component detailed drawing must be matched separately. The ledger data volume for a single large component is large, so the multi-turn dialogue context window must be large enough to hold multi-process records. Unique identifiers must also be used to separate sessions for different components to prevent data confusion.
Configuration Settings
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Dialogue context window | Previous 20 turns of dialogue or 8000 characters | Adapt to the total data volume of multi-process ledgers for a single component, avoid truncating critical records |
variables variable binding | Bind component number, pouring batch, curing kiln number | Match unique traceability identifiers and batch data for precast components, ensure prompts call the correct data sources |
chatId session identifier | Bind component QR code number | Distinguish dialogue contexts for different components, prevent data confusion across multi-component sessions |
| Prompt template | Configure by module according to document type | Adapt to the field structures of category-specific documents including detailed drawings, cutting lists, and curing records |
| Result output format | Display by process with corresponding units attached | Meet structured summary requirements for production ledgers, support easy reading by on-site personnel |
Three Common Configuration Errors
- Symptom: The
chatIdparameter is passed in an API call, but the identifier is not logged in the conversation history. Cause: ThechatIdis not bound to the unique traceability number of the precast component, so the system cannot correctly associate the session. - Symptom: The custom prompt template cannot extract exclusive fields from a rebar cutting list. Cause: Category-specific fields such as rebar specification and cutting length are not bound in
variables, so the template cannot match the actual data structure. - Symptom: Multi-turn dialogue output omits the latest curing kiln records. Cause: Data pulls are not triggered per the per-kiln update frequency, so the context does not include the most recent curing data.
How to Verify Correct Configuration
- Initiate a ledger query dialogue for a single component, confirm the session identifier matches the component QR code number.
- Call fields bound in
variables, confirm the prompt template correctly extracts exclusive data such as rebar specification and curing strength. - Initiate multi-turn process follow-up questions, confirm the context window retains prior pouring and curing record content.
- Check the API return result, confirm the
chatIdparameter is correctly logged in the conversation history.
