What this category of data looks like
Data for hazardous chemicals storage and transportation comes from three sources: the hazardous chemical safety supervision filing platform, the enterprise's own storage and transportation ledger, and compliance inspection reports. Filing data includes fixed fields such as product name, UN number, storage threshold, and transportation route, with updates synchronized every 90 days. Ledger data includes fields such as real-time storage volume, inspection records, and equipment status, with updates synchronized daily. Most document formats are structured tables or standardized reports. Field units include exclusive measurement standards such as degrees Celsius, tons, and cubic meters. UN numbers follow a fixed 5-digit numeric format.
What constraints these characteristics impose on the "workflow orchestration" link
Fixed field formats require workflow nodes to support precise matching of identification fields such as UN numbers to avoid retrieval result deviations. Exclusive measurement units require workflow configuration to verify unit consistency between input parameters and data fields to prevent compliance judgment errors. Differentiated update cycles require associated knowledge bases to set different synchronization periods to ensure data timeliness. Multi-dimensional compliance fields require workflows to split different retrieval nodes to avoid single retrieval overload that affects response speed. FastGPT v4.17.0 workflow nodes must adapt to these characteristics, otherwise retrieval matching errors or data synchronization issues may occur.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Knowledge base synchronization interval | Set in two categories: filing database at 90 days, ledger database at 1 day | Matches the update cycles of hazardous chemicals storage and transportation filing data and ledger data |
variables | Bind UN number, storage temperature, compliance threshold fields | Corresponds to core identifiers and compliance parameters of hazardous chemicals storage and transportation data |
nodeId | Bind the unique identifier of the retrieval node | Used to accurately associate retrieval nodes for hazardous chemicals storage and transportation data |
| File upload node permissions | Enable upload of images and PDF documents, limit single file size to no more than 1000 MB | Adapts to upload requirements for on-site storage and transportation inspection images and compliance report documents |
| Node timeout setting | 600 seconds | Matches the response duration for cross-departmental retrieval of hazardous chemicals compliance data |
| Search recall count | Top 8 entries | Balances retrieval efficiency and completeness of compliance information |
Three common errors
- No selectable values appear in the interface dropdown when selecting knowledge base reference variables. The cause is that core data fields for hazardous chemicals storage and transportation are not bound to the
variablesparameter. - Database connection nodes cannot accept port number input. The cause is that the advanced configuration permission of the node is not enabled, or the database driver does not adapt to the dedicated database type of hazardous chemicals ledgers.
- Multiple users cannot access via QR code after the workflow is published. The cause is that sharing permissions are not set or the workflow is not configured for public access.
How to confirm the configuration is complete
- Enter the workflow's variable configuration page, check whether core fields of hazardous chemicals storage and transportation have been bound.
- Trigger a test call, upload inspection images or compliance documents related to hazardous chemicals storage and transportation, confirm that the file upload node receives the files normally.
- Manually trigger the workflow, check whether the knowledge base retrieval results include compliance data of the corresponding category.
- Check whether the port number configuration item of the database connection node can be normally entered and saved.
