What the data for this category looks like
Data sources for commercial vehicle intelligent due diligence reports include public security traffic management vehicle registration databases, freight company operation and maintenance ledgers, third-party commercial vehicle tracking platforms, and insurance claims archives. Core vehicle qualification data is synchronized every quarter. Operation and tracking data is pulled daily. Claims data is accessed in real time. Single reports have a fixed document structure. Fields include Vehicle Identification Number (VIN), total mass, rated load mass, annual inspection validity period, operating mileage in the past 12 months, number of claims, maintenance records, and more. Most field units are kilograms, kilometers, and counts.
What constraints these characteristics impose on deployment and upgrade
Multiple data sources with different update frequencies require layered synchronization scheduling rules during deployment. Separate quarterly synchronization for qualification data, daily pulling for tracking data, and real-time access for claims data. This prevents repeated pulls or missed updates. Fixed document structures and inconsistent field units require preset unit conversion logic during deployment. This adapts to reporting habits across different regions. If data parsing rules are adjusted during an upgrade, retain parsing branches compatible with old reports. This prevents existing due diligence reports from failing to parse correctly. The real-time claims data link needs a downgrade plan configured. This avoids core data loss if the interface is interrupted during an upgrade.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single commercial vehicle due diligence reports include multiple pages of maintenance records and long-text operation analyses. Standard timeout durations are insufficient for complete parsing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Reports containing high-definition maintenance photos and operation ledgers have large file sizes. Upload limits must be expanded to support full document coverage |
VECTOR_SEARCH_TOP_K | Top 15 entries | Commercial vehicle due diligence data has many field dimensions. A sufficient number of related fragments must be retrieved to cover all retrieval requirements |
PARSE_CHUNK_SIZE | 800–1200 characters | Reports include both structured fields and long-text maintenance records. This chunk length balances parsing accuracy and retrieval efficiency |
DOCKER_IMAGE_TAG | v4.8.10 | This version resolves concurrency conflicts in multi-source data synchronization. It adapts to the high-frequency update scenarios of commercial vehicle due diligence |
WEBHOOK_VERIFY_ENABLE | true | Enabling public network address verification prevents verification failures during third-party access, corresponding to access errors in public scenarios |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on internal samples before finalizing settings.
Three common misconfigurations
- Issue: When performing a version upgrade, pulling the
v4.8.10image results in an actual running version of4.1.16. Cause: The full image tag path was not specified. The default pull was for an older, non-stable branch image. - Issue: When configuring DingTalk access and publishing an application, a prompt appears stating "Receiving message address verification failed". Cause: The
WEBHOOK_VERIFY_ENABLEconfiguration was not enabled, or the service port was not exposed for public network access. - Issue: After offline deployment, version updates cannot be performed. Existing configurations cannot adapt to new data source interfaces. Cause: Dependency packages and parsing templates for the target version were not downloaded in advance. Update resources cannot be pulled in an offline environment.
How to confirm configurations are correct
- Upload a complete commercial vehicle due diligence report. Check that the parsing task status is successful, and that extracted fields match the original document content.
- Trigger a multi-source data synchronization task. Review synchronization logs for no repeated pulling or timeout errors. Verify that field unit conversion results follow preset rules.
- Adjust
DOCKER_IMAGE_TAGto the target version and restart the service. Check that the version information output in the console matches the specified tag. - Configure a test message for DingTalk access. Send a test request and confirm that the receiving and response links are normal, with no verification error prompts.
