Cross-Review of Technical Documentation for Rubber Mixing and Product Vulcanization: Deployment and Upgrade

The daily documents for this category include formula sheets, weighing logs, mixing curves, rubber compound quick tests, vulcanization process cards

Data characteristics for this category

The daily documents for this category include formula sheets, weighing logs, mixing curves, rubber compound quick tests, vulcanization process cards, mold records, and finished product performance reports. Data comes from formula management systems, raw material batches, internal mixers, Mooney viscometers and rheometers, vulcanizers, and laboratory equipment. Updates are performed per rubber load, production batch, and mold cycle. Individual documents contain precise numeric parameters such as mixing temperature, vulcanization time, and rubber compound hardness. Most document structures combine structured forms and time-series curves.

Constraints on deployment and upgrade

The high update frequency of this category’s data and the inclusion of precise process parameters in individual documents require storage configurations adapted to high-frequency writes to avoid data synchronization delays. The mixed structure of structured and unstructured documents requires index configurations that balance matching logic for both text fields and numeric parameters. Document relationships in production scenarios are closely linked, so deployments must ensure retrieval results cover all associated documents for a single batch. Upgrade processes must avoid interrupting real-time data synchronization tied to production, and a gray-scale switching window must be reserved to ensure business continuity.

How to set configurations

STORAGE_S3_ENDPOINTLocal object storage gateway addressAdapt to enterprise intranet data storage compliance requirements, avoid cross-network transmission delays
Single recall limitTop 15 entriesCover retrieval requirements for multiple associated documents per batch
Context length800–1200 charactersAccommodate core parameters of a single vulcanization process card and mixing curve

Three common configuration mistakes

  • Unresponsive access interface, with status code 502 returned. The cause is that the MONGODB_URI configuration does not point to an available replica set node, or the intranet firewall blocks database port communication.
  • No image indexing option appears after uploading documents to the knowledge base. The cause is that the local deployment did not configure FILE_TOKEN_KEY and enable the file parsing plugin, making it impossible to extract and index image text.
  • A version update prompt pops up every time a new conversation is opened. The cause is that FE_DOMAIN is not configured with the intranet access domain name, and the default public network update address triggers frequent verification.

How to verify correct configuration

  • Run the database connection test command to verify that the replica set node configured via MONGODB_URI can read and write data normally.
  • Upload a mixing curve document, and check whether the image text analysis result is included in the knowledge base index list.
  • Modify FE_DOMAIN to the intranet access address, restart the front-end service, and verify that the version update prompt no longer appears.
  • Use the built-in retrieval tool of FastGPT v4.17.0 to send a request, and confirm that the retrieved results include matching formula sheets and vulcanization process cards.
