What the data for this category looks like
Policy data for hazardous chemicals storage and transportation comes from official public documents and mandatory national standards issued by the Department of Hazardous Chemicals Supervision of the Ministry of Emergency Management, the Water Transport Bureau of the Ministry of Transport, and the Ministry of Ecology and Environment. Update schedules adjust based on new policy releases, with no fixed cycle. Documents are grouped by regulatory hierarchy into four categories: laws, administrative regulations, departmental rules, and industry standards. They are also grouped by storage and transportation scenarios into modules including warehousing, road transportation, waterway transportation, and loading and unloading operations. Fields include regulatory document number, effective date, applicable scenario, compliance clauses, and penalty basis. Effective dates use the YYYY-MM-DD format. Individual document lengths range from hundreds to thousands of words.
What constraints these characteristics impose on deployment and upgrade
Multi-source, heterogeneous official policy documents require deployments to support batch offline import and scheduled synchronization functions. Configure a stable object storage service to store original documents. Non-fixed update schedules require upgrade processes to support flexible adjustment of synchronization cycles. Do not use mandatory fixed incremental update tasks. Structured metadata fields require deployments to pair with a relational database to store information such as regulatory document numbers and effective dates. This setup supports precise retrieval by scenario and timeliness. The wide range of individual document lengths requires configuring a reasonable retrieval link. This prevents timeouts caused by loading too much content in a single request.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
STORAGE_S3_ENDPOINT | https://s3-cn-north-1.amazonaws.com (or enterprise-built storage nodes) | Stores imported original hazardous chemicals policy documents in batches, matching the storage region of official data sources |
PG_URL | postgresql://admin:secure_pass@db-host:5432/huagong_policy | Stores metadata for hazardous chemicals policies (regulatory document number, effective date, etc.), supporting filtering and retrieval by scenario and effective time |
REDIS_URL | redis://default:redis_pass@redis-host:6379/1 | Caches frequently retrieved policy Q&A results to reduce database access pressure |
DB_MAX_LINK | Top 15–25 entries | Sets the retrieval limit for hazardous chemicals policy documents, avoiding redundant returned content that affects answer accuracy |
FILE_TOKEN_KEY | Randomly generated 32-character string | Encrypts access tokens for imported policy documents to secure access to original data |
Three common mistakes
- Issue: Pull failures occur when using the v4.8.15-fix2 Docker image. This happens because the image for this version was not synced to the official public image repository. Use the official stable version image of FastGPT v4.17.0 or higher instead.
- Issue: The overseas SaaS version fails to respond normally after login-free sharing. This occurs because cross-regional access permissions for hazardous chemicals policy data are not configured. The shared link cannot load locally stored policy documents as a result.
- Issue: Retrieval results are missing newly released hazardous chemicals policies after a system upgrade. This happens because the metadata synchronization task was not executed. New policy documents were not imported into the system, and metadata was not updated.
How to confirm proper configuration
- Access the backend management page corresponding to the configured
FE_DOMAIN. Check whether the import list for hazardous chemicals policy documents includes all target files. - Enter standard search terms for testing, such as "hazardous chemicals warehousing compliance requirements". Verify that returned results include correct regulatory document numbers and effective dates.
- View the cache instance corresponding to
REDIS_URL. Confirm that cached records exist for frequently retrieved results. - Log in to the database corresponding to
PG_URL. Check whether required fields such as regulatory document number and effective date are written into the metadata table.
