What the data for this category looks like
The data related to dairy processing equipment inspection and maintenance Q&A comes from milk source testing systems, MES systems, homogenization and heat treatment equipment, online temperature and flow monitoring systems, CIP systems, and LIMS. Daily documents include raw milk acceptance records, standardized ingredient lists, pasteurization or UHT sterilization records, CIP cleaning records, filling records, sample retention and microbial test reports. Data is updated in real time per milk tank and per batch. Fields include raw material physicochemical indicators, equipment operating parameters, batch numbers, test results, and some parameters have units such as temperature, flow rate, and time.
Constraints on the deployment and upgrade phase
Real-time synchronized batch data requires support for high-frequency concurrent read and write during deployment. Sufficient database connection and cache resources must be configured. Multi-source heterogeneous document formats, including equipment logs, test reports, and production records, require adaptation to multi-format parsing during deployment to avoid data loss or parsing errors. Fine-grained update rules per milk tank or batch require setting reasonable retrieval shards and context lengths to prevent retrieval redundancy or result overload. In intranet deployment scenarios, cross-system data synchronization stability must be ensured to avoid question and answer response speed being affected by network latency.
Configuration Settings
The following configurations apply to FastGPT v4.17.0, and are adapted for the intranet deployment scenario of equipment inspection and maintenance Q&A.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Adapts to concurrent read and write requirements for multi-batch real-time data in dairy processing, avoids database connection exhaustion, and ensures synchronization efficiency of equipment parameters and production records |
REDIS_URL | Intranet dedicated cache instance, 8 GB–16 GB memory configuration | Stores frequently accessed equipment inspection rules and batch data, reduces database query pressure, and improves Q&A response speed |
STORAGE_S3_ENDPOINT | Intranet object storage service address | Stores large-volume documents such as equipment logs and test reports, adapting to intranet deployment scenarios without public network access |
FE_DOMAIN | Intranet service domain name or IP:port | Limits frontend access scope, complying with security and compliance requirements for intranet deployment |
FILE_TOKEN_KEY | Randomly generated 32-character string | Encrypts access tokens for internal documents, preventing unauthorized access to sensitive production data |
ROOT_KEY | Strong password string for intranet environments | Configures the system's highest permission key, only used for backend operations by intranet administrators |
Three Common Misconfigurations
- Phenomenon: After deploying with the Qwen2.5 model, the interface returns the error "Model does not support tool call format" when triggering tool calls. Cause: Correct model call parameters were not configured during deployment, and context adaptation rules for tool calls were not enabled, causing the model to fail to recognize tool call instructions.
- Phenomenon: After upgrading FastGPT, CIP cleaning records in the original knowledge base cannot be retrieved normally, and the returned result is empty. Cause: The knowledge base's document chunking rules were not updated synchronously, and the new chunking parameters do not match the storage format of the original documents, causing retrieval to fail to match results.
- Phenomenon: During intranet deployment, single equipment inspection Q&A response times out. Checking backend logs shows that database query time is too long. Cause: Reasonable memory parameters for
REDIS_URLwere not configured, cache hit rate is insufficient, and frequent access to the database during high-frequency equipment parameter queries leads to response delay.
How to Verify Correct Configuration
- Log in to the FastGPT backend management interface, check that the configuration value of
DB_MAX_LINKmatches the preset value, view the database connection count monitoring panel, and confirm that no connection exhaustion alerts are triggered. - Upload a standard raw milk acceptance record document, verify that document chunking and retrieval functions operate normally, and that the number of returned results conforms to the configured retrieval upper limit rules.
- Test calling the built-in time query tool, confirm that the tool call process triggers normally and returns correct time information.
- Check intranet firewall and security group rules, confirm that the port corresponding to
FE_DOMAINis not blocked, and that the frontend page can load and access normally.
