What data for this category looks like
Data for this category comes from steel coil labels and quality certificates, press and feeder operation data, mold management systems, MES systems, coordinate measuring machine or fixture inspection data. Daily documents include stamping work instructions, material utilization rate sheets, mold inspection sheets, first/last piece records, dimensional inspection reports, and mold change records. Each document contains fields such as material grade, mold number, mold change time, dimensional tolerance, batch number, and more. Units include millimeters, tons, hours, and more. Data is updated per coil of material, each batch of materials, or each mold change.
Constraints Imposed on Deployment and Upgrade by These Characteristics
The high-frequency, scattered update rhythm of data requires storage and retrieval links configured during deployment to support high-frequency small-batch data writes, to avoid link congestion. Multi-source heterogeneous data sources require unified format conversion rules to be configured during the deployment phase, to adapt to document structures exported by different systems. Documents contain a large number of professional parameters and associated fields. The retrieval link must accurately match field dimensions to complete cross-review. Frequent mold changes and batch changes require retaining version traceability capabilities for historical data during upgrades, to prevent cross-batch data confusion from affecting review accuracy. Cross-review of technical documents requires association of multiple different types of documents. Field mapping logic must be planned in advance before deployment, to ensure documents from different sources can be effectively associated.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 8–12 documents | This category generates multiple associated documents per coil of material or each mold change. It must support associating 8–12 documents to complete cross-review, calibrated based on actual measurements |
REDIS_URL | Local port 6379 | This category has frequent data updates. Using Redis to cache frequently retrieved mold and batch data reduces database load |
STORAGE_S3_ENDPOINT | Configured per local storage node | This category includes multi-source heterogeneous documents. It must adapt to unified object storage endpoints to ensure normal data write and read operations |
| Maximum Context Window | 12k token | This category's documents include professional parameters such as material grade and dimensional tolerance. Sufficient context must be retained to complete cross-verification and avoid truncation of critical information |
FILE_TOKEN_KEY | Randomly generated 32-character string | Used to encrypt stored file access tokens, ensuring access security for document data |
Three Common Misconfigurations
- Symptom: Context truncation occurs during model operation, and returned results lack parameters related to material utilization rate or dimensional tolerance. Cause: The model maxcontent parameter set during deployment is not unified with the maximum context parameter configured in FastGPT, and the configuration was not adjusted based on the category's document length.
- Symptom: A
MONGODB_URIconnection failure prompt appears when starting the source-deployed service, returning status code 500. Cause: TheMONGODB_URIparameter was not filled correctly, and the correct database access address and permission information were not configured. - Symptom: Cross-review results do not include the latest mold maintenance announcements or industry standard documents. Cause: The internet search function was not enabled in the lower version, or search permissions were not configured, preventing access to the latest external document data.
How to Verify Proper Configuration
- Perform a local data import test, upload a stamping work instruction and corresponding mold change record, and check whether successful association and retrieval can be completed.
- View the cache node corresponding to
REDIS_URL, and confirm that frequently retrieved mold data has been normally cached. - Start the FastGPT v4.17.0 service, and confirm that there are no database connection or storage connection related errors.
- Test multi-document associated review, and verify that the number of simultaneously associated documents matches the configured value of
DB_MAX_LINK.
