What the data for this category looks like
Data related to inspection and process record audit for plastic injection molding comes from resin batch property sheets, injection molding machine parameters, mold temperature controllers, MES systems, and dimensional and appearance inspection equipment. Daily involved documents include injection molding process cards, raw material drying records, mold history logs, first article inspection forms, patrol inspection forms, and material change and machine cleaning records. Data updates occur per production batch, each mold change or material change, and at the end of each shift. Document fields include packing, holding, and cooling parameters, drying temperature and duration, raw material regrind ratio, mold usage count, and more, with corresponding units such as ℃, seconds, %, and times.
What constraints these characteristics impose on the multi-turn dialogue and prompt engineering link
The data for this category has high update frequency, scattered sources, and highly targeted document fields. This requires multi-turn dialogue to limit context scope to avoid interference from redundant old data. Different scenarios require different document types to be called, so prompts must explicitly specify reading specific documents such as injection molding process cards and patrol inspection forms to reduce irrelevant content matching. Each batch of data is associated with a unique production identifier, so multi-turn dialogue must bind the current batch context via chatId to ensure consistency across rounds of questions. Additionally, since errors can lead to batch defects or safety issues, prompts must include data validation logic to avoid risks such as material mixing and parameter deviations.
Configuration Settings
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Context window size | First 1000–1500 characters | Matches the average length of single-batch injection molding documents, avoids exceeding model processing limits |
| Variable binding rule | Bind production batch number and mold ID via the variables parameter | Associates batch data from different data sources, ensures context consistency for multi-turn dialogue |
| Retained conversation history count | First 20 dialogue entries | Focuses on the current batch's inspection and audit process, reduces interference from irrelevant history |
| Prompt template trigger condition | Match the first 5 keywords | Automatically calls the corresponding document library to accurately locate content such as process cards and patrol inspection forms |
| Supported document parsing formats | xlsx, csv format documents | Covers common business document types such as patrol inspection forms and raw material drying records |
| Session ID binding | Fix chatId to the current production batch | Maintains context continuity for multi-turn dialogue, avoids mixing data across batches |
Three Common Misconfigurations
- Phenomenon: After uploading xlsx format raw material drying records or patrol inspection forms, the dialogue cannot recognize the field content within the table. Cause: No corresponding document format parsing rule is configured, only preset text document parsing is supported.
- Phenomenon: The dialogue cannot obtain custom content such as the production batch number entered by the user. Cause: The
variablesparameter is not correctly bound, and user input is not mapped to preset business variables. - Phenomenon: The generated dialogue history in debug preview cannot be cleaned individually, only the entire session can be cleared. Cause: Independent conversation page history management configuration is not enabled, and deletion permission for single historical records is not enabled by default.
How to Confirm Proper Configuration
- Upload corresponding documents such as injection molding process cards and raw material drying records, initiate a query containing specific parameters, confirm that matching content within the documents can be returned.
- Initiate a multi-turn dialogue, sequentially ask about parameters from different production links, confirm that
chatIdremains consistent, themessagesparameter contains complete historical dialogue content, context is coherent and associated with the current batch. - After configuring variable binding, initiate a query containing the production batch number, confirm that corresponding data such as mold history logs and material change and machine cleaning records can be associated.
- Try to clean the historical records of a specified session, confirm that the operation can be executed normally without affecting global sessions.
