What data for this category looks like
Technical documents for ready-mixed concrete production include mix design notifications, batch verification records, production and delivery slips, raw material inspection reports, test block logs, and strength test reports. Data sources include engineering orders, sand, gravel, cement, admixture inspection, moisture content testing, mixing plant control systems, and laboratory systems. Update frequencies follow per-vehicle production data, per-batch raw material inspection results, and daily summary reports. Document fields include sand and cement dosage (kg/m³), aggregate moisture content, slump (mm), test block age (days), and strength grade (MPa). Core fields vary significantly across different document types.
Constraints for deployment and upgrade
This category has frequent data updates with high real-time requirements. Every vehicle’s production data and each batch’s raw material inspection results trigger document updates. Sufficient concurrent connections must be configured during deployment to support read and write requests. Document fields have large variations and include specialized engineering parameters. Parsing rules for different documents must be adapted during deployment. Existing field mapping logic must not be disrupted during upgrades. Sensitive quality data requires secure storage. Public cloud storage is not recommended. A reliable backup mechanism must be configured to prevent data loss that could impact project quality. The deployment environment must be network-isolated from production control systems and laboratory equipment to avoid interfering with production workflows.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Ready-mixed concrete production has frequent data updates. New data is generated for every vehicle and batch. A sufficient database connection pool is needed to support concurrent read and write operations |
MONGODB_URI | mongodb://192.168.1.100:27017/concrete_docs | Documents and production data for this category must be isolated from business systems to avoid disrupting normal production workflows |
REDIS_URL | redis://:securepass@192.168.1.101:6379/0 | Frequently accessed mix design and moisture content data must be cached to reduce database load and adapt to the real-time update rhythm of the business |
STORAGE_S3_ENDPOINT | http://192.168.1.102:9000 | Files such as test reports and test block logs for this category have large sizes. Local storage ensures data security and reduces transmission costs |
FILE_TOKEN_KEY | Randomly generated 32-bit string | Generate secure access tokens for uploaded production documents to prevent unauthorized access to sensitive quality data |
Three common configuration mistakes
- Symptom: A startup error occurs after packaging for local deployment, prompting a database connection timeout. Cause: The
DB_MAX_LINKparameter was not adjusted to match the concurrent data requirements of this category. The default connection count is insufficient to support real-time document read and write requests generated per vehicle. - Symptom: Modified mix design document parsing rules do not take effect after successful packaging and operation. Cause: Front-end static resource caching was not updated synchronously during deployment, or
FE_DOMAINwas not correctly configured to point to the local deployment address. This causes the front end to load outdated code. - Symptom: Some documents fail to be indexed when uploading raw material inspection reports in bulk. Cause:
STORAGE_S3_ENDPOINTwas not correctly configured, making the storage endpoint inaccessible. The system cannot read and parse the files.
How to verify correct configuration
- Log in to the FastGPT v4.17.0 backend, access the database connection panel, and confirm that the connection status for
MONGODB_URIandREDIS_URLis normal. - Upload a recent mix design notification, check that the system correctly extracts fields such as sand and cement dosage, moisture content, and slump to verify that document parsing rules are active.
- Call the system’s bulk import interface, upload 10 test block logs, confirm no errors occur during the import process, and check that the
DB_MAX_LINKconnection count is not exhausted. - Access the address configured for
FE_DOMAIN, confirm that the front-end page loads the latest modified configuration interface with no cached content remaining.
