What the Data for This Category Looks Like
Railway and highway financial report data primarily comes from public annual and semi-annual financial reports released by transportation enterprises, plus industry statistical bulletins published by transportation authorities. Update cadence is split into quarterly and annual. Quarterly reports are compiled from monthly operational data. Annual reports cover full fiscal years. Documents typically include detailed modules such as total revenue, segment-specific turnover, maintenance costs, and asset depreciation. Fields cover total freight/passenger turnover, toll revenue, route mileage, per-mile maintenance costs, and more. Common units include hundred million ton-kilometers, CNY, kilometers, and others.
What Constraints These Characteristics Impose on Deployment and Upgrade
Railway and highway financial reports include detailed operational data across multiple segments, so individual file sizes are often large. Adjust resource configurations for upload and parsing to accommodate this. Field types and units vary widely. Preset unified conversion rules to avoid analysis bias. Reports update on a quarterly and annual basis. Configure scheduled sync tasks to match this update cadence. Fine-grained access control is required for analysis permissions across different operating entities or departments to prevent data leaks. During upgrades, retain existing sync configurations and permission rules to avoid needing to reconfigure after a reset.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000–1500 MB | Railway and highway financial reports often include multi-segment detailed attachments; individual file sizes exceed the default limits of general platforms |
PARSE_FILE_TIMEOUT_SECONDS | 600–900 seconds | Text parsing and structured processing of large financial report files require more time to prevent mid-process interruptions |
SYNC_CRON_EXPRESSION | 0 0 2 * | Matches the update cadence of quarterly reports compiled from monthly data; runs daily at 2 AM to avoid impacting business hours |
FIELD_UNIT_CONVERT | Unified conversion per preset rules | Financial reports contain multiple unit fields such as hundred million ton-kilometers and CNY per kilometer; conversion to standard analysis units is required |
MULTI_TENANT_ENABLE | Enabled | Supports separate access to eligible financial report data for different department accounts, meeting permission control requirements |
RETRIEVE_TOP_K | Top 8–12 entries | Financial reports have many field dimensions; a sufficient number of relevant text fragments must be retrieved to complete accurate analysis |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: After private deployment, multiple accounts cannot be created, and only the WeChat QR code login option appears on the login screen. Cause: The
MULTI_TENANT_ENABLEconfiguration item is not enabled; the system disables multi-account permission management by default. - Issue: Uploading railway and highway financial report files fails, and the console returns a
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEparameter has not been adjusted; the default configuration cannot handle large financial report attachments. - Issue: After local deployment, uploading a financial report file results in no response, and analysis outputs are empty. Cause:
PARSE_FILE_TIMEOUT_SECONDSis not set to a reasonable duration; large file parsing times out without triggering an exception retry mechanism.
How to Verify Successful Configuration
- Upload a single railway and highway financial report attachment larger than 500 MB. Confirm the upload completes normally with no error prompts.
- Manually trigger a scheduled sync task. Check system logs to confirm the latest financial report data has been pulled, with no sync failure records.
- Create two accounts with different permissions. Verify that each can only access financial report analysis results within their respective permission scope.
- View the list of structurally parsed fields. Confirm units have been uniformly converted per preset rules, with no unit confusion.
