What data for this category looks like
This category covers all departments in the full cement production workflow. Daily documents include raw material batching plans, kiln operation records, laboratory reports, quality control notices, equipment inspection records, energy reports, and more. Data sources include online composition analysis systems, DCS control systems, laboratory test data, kiln and grinding equipment operation data, raw and fuel ledgers, and energy metering instruments. Data update frequencies are divided into three categories: real-time, per shift, and daily. Document fields include basic production parameters such as material component ratios, equipment temperature, runtime, and batching ratios.
Constraints imposed by these characteristics during deployment and upgrade
Multi-source heterogeneous data for this category uses three update frequencies (real-time, per shift, daily) and originates from multiple sources including industrial control systems and laboratory teams. Deployment must adapt to different access protocols and permission requirements. Document structures vary significantly across production departments, so dedicated parsing rules must be configured for different document types such as raw material batching plans and kiln operation records. Stable real-time equipment parameter pull channels are required to avoid data delays during Q&A calls. Timed tasks must be configured for daily batch-synchronized laboratory data to ensure data timeliness. Equipment inspection and maintenance Q&A must link to equipment operation logs and inspection records, so sufficient context call resources must be reserved during deployment to ensure response speed for complex queries.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 records/minute | Matches concurrent requirements for real-time and batch data synchronization for this category, and adapts to data pull frequencies across multiple departments |
MONGODB_URI | Configured per enterprise internal DCS data storage nodes, with dedicated access keys | Core production data for this category is stored in industrial-grade MongoDB clusters, so dedicated permissions must be configured to ensure data security |
REDIS_URL | 1000 MB memory size instance | Real-time equipment parameters and user session context must be cached to ensure Q&A response speed |
STORAGE_S3_ENDPOINT | Configured per enterprise internal object storage nodes | Documents such as inspection records and laboratory reports for this category must be stored in enterprise-owned object storage to adapt to private deployment scenarios |
ROOT_KEY | Complex key generated per enterprise internal permission rules | Ensures security of platform management permissions and prevents unauthorized access |
Three common misconfigurations
- Issue: After upgrading FastGPT v4.17.0, creating a knowledge base using an enterprise internal data source URL triggers a backend log prompt of
cannot fetch internal url. Cause: Access whitelist for internal data sources is not configured, orSTORAGE_S3_ENDPOINTis not filled correctly to match the internal network storage address. - Issue: After deployment, the file processing plugin entry cannot be found, and inspection record documents cannot be uploaded. Cause: The loading switch for the corresponding plugin is not enabled in the deployment configuration, or the used version does not include the plugin natively.
- Issue: When deploying version 4.8.12 locally, complex formulas in raw material batching plans cannot be parsed normally. Cause: The formula parsing module in this version does not support multi-variable batching formula formats for cement categories. Upgrade to version v4.17.0 to resolve this.
How to confirm proper configuration
- Access the configured frontend domain name and verify that the platform page loads normally.
- Trigger a batch data synchronization task and check whether the configured data source can pull the corresponding documents normally.
- Submit an equipment inspection-related query and verify that the system can retrieve linked inspection records and operation parameters.
- Check backend logs to confirm that there are no error reports for cache services and database connections.
