What the data for this category looks like
Enterprises primarily source hazardous chemicals storage and transportation business data from internal storage ledgers, local emergency management department hazardous chemicals supervision systems, and third-party compliance test reports. Two update cycles apply to this data: daily storage ledgers are synchronized and updated daily, while regulatory and compliance data is updated quarterly. Document structures include fixed fields: general hazardous chemical name, CAS registration number, storage area number, temperature and humidity safety thresholds, and compliance approval number. Legal measurement units such as cubic meters, degrees Celsius, and kilograms are used uniformly. The length of individual documents varies widely, ranging from hundreds to thousands of characters.
What constraints these characteristics impose on forms and interactions
Hazardous chemicals storage and transportation business data has many fields and strict compliance requirements. Forms must mandatorily match required fields such as CAS number and storage location to prevent non-compliant information from being entered. Differences in data update frequencies require form interactions to support dynamic loading of the latest regulatory data, avoiding calls to expired information. The wide variation in individual document length requires form input areas to accommodate long text entry. Forms must also limit the number of documents submitted in a single batch to prevent excessive system load. Additionally, the mandatory requirement for legal measurement units requires preset unit options in the form to avoid compliance issues caused by users entering non-standard units independently.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput length | 800–2000 characters | Matches the length range of individual hazardous chemicals storage and transportation documents to avoid content truncation |
userSelect options | Preset CAS number, storage area | Corresponds to fixed fields in business data, reducing non-standard input |
| Rearrangement configuration | Top 5 results | Adapts to the recall volume of hazardous chemicals compliance data, ensuring core information is displayed first |
| Single submission limit | 3 documents | Prevents excessive data submitted in a single batch from causing system load abnormalities |
| Timeout period | 600 seconds | Matches the average response time of compliance data queries, preventing mid-process interruptions |
| Context window | 12000 token | Adapts to the context transfer requirements of long documents, ensuring complete reading of compliance clauses |
Three common errors
- Symptom: Calling a custom channel interface triggers a "Model not matched" error. Cause: The channel's interface address and key are not configured correctly, or an incompatible model type is selected.
- Symptom: Submitting a form triggers a "Field format invalid" error, and the corresponding field is the CAS number. Cause: No CAS number format validation rule is configured for the
formInputcomponent, allowing users to enter non-standard characters. - Symptom: Submitting a long document triggers a response timeout. Cause: The timeout period is set too short, not matching the query response time of hazardous chemicals regulatory data.
How to confirm the configuration is complete
- Open the form configuration page, and verify that the preset options of the
userSelectcomponent include the core fields of hazardous chemicals storage and transportation. - Submit a test document that conforms to the standard format, and confirm that submission and data validation complete normally.
- Call the inquiry interface, and confirm that the number of returned results matches the value set in the rearrangement configuration.
- Check the system logs, and confirm that no interface timeout errors occur within the configured timeout period.
