What this category of data looks like
Data sources include customer drawings, special characteristic lists, ERP/MES systems, measuring tools, equipment process parameters, and supplier quality certificates. Daily output includes structured documents: control plans, process flow diagrams, work instructions, first-piece and patrol inspection records, SPC reports, PPAP materials, and 8D reports. Collect data continuously by production batch and work shift. Fields include equipment operating parameters, measured dimensional tolerances, batch pass rates, and more. Attach clear unit identifiers: revolutions per minute, newton-meters of torque, millimeters for dimensions.
Constraints for deployment and upgrade
Scattered data sources link tightly across systems. Integrate multi-system interfaces during deployment to adapt to different document and parameter formats. Update frequency is high, with strict real-time requirements. Configure the knowledge base synchronization mechanism to support batch or scheduled updates. Vehicle customer quality systems impose strict constraints. Retain historical version traceability during upgrades to avoid changing compliance for delivered batches. Document structures are fixed, with standardized fields. Adapt the deployed document parsing module to specific formats such as control plans and 8D reports. Do not adjust field mapping rules arbitrarily.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Support concurrent access for multi-equipment and multi-batch data, avoid exhausting database connections |
MONGODB_URI | Point to a dedicated MongoDB instance for equipment inspection records and maintenance logs | Isolate business data from other system data, ensure compliance for automotive component manufacturing |
REDIS_URL | Configure as a local cache node, set cache validity to 300 seconds | Quickly retrieve frequently accessed equipment parameters and work instructions, reduce database load |
STORAGE_S3_ENDPOINT | Bind to the access address of the enterprise's internal object storage service | Uniformly store compliance documents including batch-produced inspection reports and PPAP materials |
ROOT_KEY | Generate a dedicated key per enterprise internal permission management rules | Control highest-privilege access to the FastGPT platform, meet vehicle customer security audit requirements |
Three common configuration errors
- Symptom: Model stream response is empty when calling built-in tools. Cause: Cache failure from incorrect
REDIS_URLconfiguration, leading to failed context synchronization for tool calls. - Symptom: Deployed model fails to generate required maintenance suggestions during thinking phases. Cause: Exclusive business documents such as equipment parameters and work instructions were not imported into the knowledge base, so the model lacks scenario-specific data support.
- Symptom: Database permission errors occur after restarting Docker containers. Cause: Database access permissions were not reconfigured, or correct storage volumes were not mounted, preventing FastGPT from reading historical production data.
How to verify correct configuration
Run a database connection test to confirm DB_MAX_LINK supports concurrent requests from current production equipment. Upload a control plan document to check if the system correctly parses special characteristic fields and associates them with corresponding production equipment. Trigger a knowledge base synchronization task to confirm batch-updated documents complete synchronization within the preset cycle. Calibrate thresholds based on actual measurements. Use FastGPT v4.17.0 built-in tools to verify tool calls return normal results. Restart Docker containers, then test database and object storage access permissions to confirm no permission-related errors.
