What the Data for This Category Looks Like
Data sources for this category include DCS/SIS control systems, online process analyzers, LIMS laboratory management systems, equipment condition monitoring systems, energy metering devices, and raw material tank level monitoring nodes. Daily documentation includes operating procedures, process indicator cards, DCS trend charts, laboratory analysis reports, interlock bypass records, special work permits, and shift handover logs. Data update frequencies fall into three categories: real-time (such as DCS parameters and alarm records), per-shift (such as shift reports and work permits), and daily (such as laboratory reports and energy consumption statistics). Document fields include exclusive identifiers such as process parameter units (like MPa, ℃, t/h), interlock logic numbers, and material component proportions.
What Constraints Do These Characteristics Impose on Deployment and Upgrade
When deploying the open-source version of FastGPT v4.17.0, the data characteristics of this category create multiple constraints for deployment and upgrade. Multi-source heterogeneous data source access requires reserved driver loading configurations for different industrial protocols to support connections with systems such as DCS and LIMS. Real-time data update frequencies require adjustments to database connection pool parameters to handle high-frequency writes and avoid data synchronization delays. Structured parsing for multiple document types requires compatibility with template rules for different formats, such as operating procedures and interlock bypass records, during upgrades. High-confidence verification requirements demand additional dedicated verification nodes for interlock logic and process parameters to ensure the accuracy of cross-review.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
DB_MAX_LINK | 300–500 connections | Adapts to connection requirements for real-time data high-frequency writes and parallel parsing of multiple documents, avoiding connection exhaustion |
MONGODB_URI | Points to the local cluster address of the mongo:4.4.29 version | Compatible with scenarios where some legacy hardware does not support AVX instruction sets, aligning with on-site actual deployment conditions |
REDIS_URL | redis://:custom password@intranet address:6379/0, set connection timeout to 60 seconds | Supports real-time data caching and session synchronization, adapting to batch document processing per shift and daily |
STORAGE_S3_ENDPOINT | Intranet address of the enterprise internal object storage | Reduces cross-public network transmission delay, meeting high-security data storage requirements for chemical production sites |
FE_DOMAIN | https://enterprise intranet FastGPT exclusive domain name | Adapts to enterprise intranet access requirements, avoiding public network exposure of sensitive production data |
Three Common Misconfigurations
- A 500 error returns when accessing an interface, with the prompt
未配置商业版链接(unconfigured commercial version link). The root cause is that the open-source deployment did not remove plugin configuration items dependent on the commercial version, causing the system to attempt to call an undeployed commercial interface. - A locally built image fails to start, with the prompt
proAPI folder does not exist. The root cause is that the open-source deployment package does not include the commercial version plugin directory. Delete related reference configurations during the build process to resolve this. - After replacing
MONGODB_URIwith the specified version, the system prompts that the version is too low during startup. The root cause is that the MongoDB version compatibility parameter was not adjusted in the system configuration, causing version verification to fail.
How to Confirm the Configuration Is Complete
- Access the intranet address corresponding to
FE_DOMAIN, and confirm that the front-end page loads normally with no configuration error prompts. - Run the
GET /api/core/getPluginGroupsinterface, and confirm that the return status code is200with no commercial version-related errors. - Upload a process indicator card document to the system, and confirm that the parsed fields include exclusive identifiers such as process parameter units and interlock numbers.
- Check the cache node associated with
REDIS_URL, and confirm that real-time data synchronization delay meets on-site business requirements.
