What the data for this category looks like
The business data for ready-mixed concrete production comes from engineering orders, sand, gravel, cement and admixture testing, moisture content measurement, mixing plant control systems, and project laboratories. Data update frequencies are per vehicle, per batch of raw materials, and daily. Covered documents include mix proportion notices, opening identification forms, production and transport slips, raw material inspection records, test block records, and strength reports. Data fields include raw material inspection parameters, production execution parameters, and test block test results. Units include standard units related to mass, volume, and strength. The content volume of a single production record varies with batch scale.
What constraints these characteristics impose on the multi-turn dialogue and prompt engineering link
Ready-mixed concrete production data has strong real-time performance, high update frequency, and is strongly tied to specific production batches. This requires multi-turn dialogue to pull the latest raw material inspection and production records in real time, avoiding expired data. The fixed structure of business documents requires multi-turn prompts to explicitly specify the fields to extract from corresponding documents, ensuring audit logic aligns with core processes of raw material inspection, production adjustment, and test block verification. The batch-binding nature of data requires that dialogue context be limited to the current batch, preventing mixing of audit data from different batches. Additionally, the consequences of quality audit errors are severe, so multi-turn dialogue must add verification steps to ensure every adjustment meets requirements.
How to set the configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind to the unique number of the current production batch | Ensure dialogue context for the same batch is not interfered with by other batches |
messages | Limit context to the last 4 business records | Match the update frequency of per vehicle and per batch of raw materials, comply with FastGPT v4.17.0 context limiting rules, and avoid redundant data occupying context |
variables | Inject raw material moisture content and mix proportion parameters for the current batch | Pull corresponding fields in real time from mixing plant control systems and laboratory data sources |
| Streaming output interval | 1–2 seconds | Adapt to front-end display rhythm, reduce perceived waiting time |
| Dialogue log export | Support exporting full records by batch | Meet the requirement of extracting full dialogue records |
| Multi-turn prompt template | Organize according to the process of raw material inspection → production adjustment → test block verification | Align with core business links of ready-mixed concrete production |
Three common mistakes
- Phenomenon: Streaming output returns at a fixed 4-second interval, and cannot be adjusted to the preset 1–2 seconds. Cause: The streaming output interval parameter is not configured, and the system default setting is used.
- Phenomenon: Fields are mixed after multi-turn dialogue outputs from different batches are spliced, and batch information cannot be aligned. Cause: The batch unique identifier is not bound via
variables, resulting in mixed output content from different batches. - Phenomenon: Dialogue log export only returns the current conversation fragment, and full historical records cannot be obtained. Cause: The batch-based log export configuration is not enabled, and only the temporary log interface for a single conversation is called.
How to confirm the configuration is correct
- Initiate a simulated production batch dialogue, check whether
chatIdis bound to the correct batch number, and whether the context only contains business records for the corresponding batch. - Trigger streaming output, observe whether the fragment intervals returned by the front end meet the preset range requirements.
- Attempt to export the dialogue log, confirm that all multi-turn dialogue content for the current batch can be obtained.
- Verify that the parameters injected via
variablesmatch the real-time production data of the current mixing plant.
