What the Data for This Category Looks Like
The data for this category originates from the road transport administration system, the national road transport vehicle dynamic information public service platform, and the vehicle and practitioner database. Updates occur daily. Daily documents include business license applications, vehicle technical files, driver qualification materials, safety production management systems, road transport business licenses, and other related materials. Document structures include fields such as license number, vehicle identification number, qualification certificate number, and safety system clauses. Most fields are string or numeric identifiers, with no complex nested structures.
What Constraints These Characteristics Impose on Deployment and Upgrade
Daily updated multi-source data requires stable database connections and cache services to be configured during deployment, to avoid synchronization interruptions. Document types vary widely in length: some application materials are hundreds of characters long, while safety management systems can be thousands of characters. Chunking rules must be adapted for different document lengths. Errors in the data verification stage lead to license rejection, so Q&A matching must accurately associate key fields in documents. During the upgrade process, the association relationships of the existing knowledge base must be preserved.

How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 10–20 connections | Support daily batch transport administration data synchronization and Q&A retrieval requests |
REDIS_URL | standard address of local cache service | Store Q&A session cache and embedding results, reduce repeated retrieval overhead |
STORAGE_S3_ENDPOINT | object storage endpoint configured according to deployment environment | Store uploaded road transport documents and archive materials |
| Chunk Length | 800–1200 characters | Adapt to the average length of road transport documents, avoid damaging business logic through chunking |
| Overlap Length | 100–200 characters | Connect adjacent chunks, retain key business information across chunks |
ROOT_KEY | key configured according to deployment permission requirements | Perform permission verification for the management backend, control configuration modification and data synchronization permissions |
Three Common Misconfigurations
- Symptom: After the knowledge base is split, extremely long safety management system documents are directly truncated, and Q&A cannot match complete clauses. Cause: No adaptation rules are configured for long documents, and only default separators are used to process ultra-long content without truncation.
- Symptom: Daily data synchronization tasks time out, returning a 504 status code. Cause: The
DB_MAX_LINKconfiguration value is too low, unable to support batch data synchronization requests. - Symptom: Calling the Q&A interface with an application-specific key returns a 403 error. Cause: The usage scenarios of the application-specific key and the universal key are confused, and the key is not bound to the corresponding party building learning Q&A application.
How to Confirm Configuration Completion
- Access the management backend, verify that the cache service referenced by the
REDIS_URLconfiguration item connects normally. - Upload a single road transport business license application document, confirm that chunking results do not lose key fields such as license number and applicant information.
- Use the configured
ROOT_KEYto verify management permissions, confirm that a normal status code is returned. - Trigger a batch data synchronization task, confirm that no abnormal error reports occur in the database connection.
