Data Characteristics for This Category
This category covers suppliers of automotive braking, steering, chassis, interior, exterior, and powertrain systems. Daily generated documents include control plans, process flowcharts, work instructions, first-piece and patrol inspection records, SPC reports, PPAP materials, and 8D reports. Data sources include customer drawings and special characteristic lists, ERP/MES systems, measurement and inspection tool collection data, equipment process parameters, and supplier quality certificates. Data updates occur per production batch, shift patrol inspections, and continuous equipment parameter collection. Each document includes fields such as version number, batch number, characteristic parameters, and inspection values, with supporting physical units including torque, pressure, and millimeters.
Constraints for Deployment and Upgrade
Multi-source, heterogeneous data sources require deployments to support connections for different data formats, avoiding metadata mapping errors. High-frequency batch updates require deployments to include incremental synchronization mechanisms, preventing full synchronization from consuming excessive system resources. Diverse document types require configured parsing rules to ensure key fields from technical documents are extracted correctly. Quality system requirements enforced by vehicle customers require data isolation and access permission controls during deployment and upgrade, preventing leakage of sensitive customer special characteristic materials. The continuity of batch production requires upgrade operations to avoid interrupting core data synchronization, as this would impact the document cross-review process for production steps.
Configuration Settings
This configuration applies to FastGPT v4.17.0
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 200–300 connections | Adapts to concurrent requests in high-volume manufacturing scenarios, preventing database connection exhaustion from affecting synchronization and review of multi-batch documents |
PG_URL | postgresql://{db_user}:{db_pass}@{db_host}:5432/fastgpt_car_parts | Connects to structured business data stored in ERP/MES systems, supporting batch transaction operations and metadata queries |
REDIS_URL | redis://:{redis_pass}@{redis_host}:6379/0 | Caches high-frequency batch inspection data and document metadata. Set the cache expiration time to 300 seconds to adapt to shift-based update frequencies |
STORAGE_S3_ENDPOINT | http://minio.internal:9000 | Stores large files such as batch-generated SPC reports and PPAP materials. Supports storing documents up to 1000 MB per file, adapting to storage requirements for various business files |
FE_DOMAIN | https://docs-review.car-parts-manufacture.com | Binds a dedicated business domain name to ensure consistency between the interface and API calls, adapting to internal employee access scenarios |
FILE_TOKEN_KEY | 32-bit random encryption string | Encrypts document download links to prevent unauthorized access to sensitive materials such as customer drawings and quality certificates |
Three Common Configuration Errors
- The optional list is empty after importing a knowledge base. The symptom is that no options appear in the knowledge base drop-down menu on the document import interface. The cause is that
PG_URLis not correctly configured to point to the database storing business document metadata, and metadata synchronization for batch documents has not been completed. - The interface language switches to English after an upgrade. The symptom is that all interface text appears in English after logging in, and knowledge base category labels display English content. The cause is that Chinese localization configuration was not loaded during deployment, or the environment variable bound by
FE_DOMAINwas not correctly associated with the language pack path. - Batch document downloads return a 403 error. The symptom is that clicking a document link fails to open normally, and a 403 status code is returned. The cause is that the encryption key for
FILE_TOKEN_KEYwas not correctly configured, causing download token verification to fail.
How to Verify Proper Configuration
- Access the address bound to
FE_DOMAIN, confirm the interface language is Chinese, and the knowledge base list displays categories for business documents such as control plans and SPC reports. - Run a single document import task, confirm that after the import completes, the knowledge base drop-down menu shows the uploaded business documents.
- Upload a simulated SPC report file, confirm the file can be accessed normally through the storage service corresponding to
STORAGE_S3_ENDPOINT, and the download link opens correctly. - Check the database connection monitoring panel, confirm the current database connection count does not exceed the threshold set by
DB_MAX_LINK, and there are no connection timeout errors.
