What This Category’s Data Looks Like
The core data for this category originates from highway maintenance management systems, bridge and tunnel monitoring systems, road patrol systems, and traffic flow monitoring data, and is updated daily. Daily processed documents include maintenance plans, patrol logs, defect disposal orders, road construction permits, and road damage compensation forms. Each document contains fields such as facility number, defect type, disposal time limit, compensation amount, and construction scope, with units including kilometers, square meters, cubic meters, yuan, and others. Some documents must be linked to historical patrol records and approval files for corresponding road sections.
What Constraints These Characteristics Impose on Deployment and Upgrade
Multi-source data updated daily requires a stable multi-data source synchronization link to be configured during deployment, to avoid data delays that compromise review timeliness. Field differences across multiple document types require adaptation of parsing rules for different documents during upgrades, to prevent field extraction errors. Scenarios requiring linkage with historical data, such as road construction permits and road damage compensation forms, require reserving interface space for cross-system data linkage during deployment. Additionally, because data involves road safety and fund management, permission control configuration must be strengthened during deployment to block unauthorized access. Document formats may have minor variations across different maintenance units, so a flexible custom parsing configuration entry must be retained during upgrades.
How to Configure Settings
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 100–200 connections | This category’s daily updated multi-source data generates a high volume of database connection requests. This value balances connection count and resource utilization. |
MONGODB_URI | Set based on actual measurements | Historical patrol records from the road patrol system must be linked, so configure the access address of the corresponding business database to adapt to multi-source data storage needs. |
REDIS_URL | redis://:custom password@host address:6379/0 | Used to cache frequently accessed road section defect data and review rules, reduce database query pressure, and ensure review response speed. |
STORAGE_S3_ENDPOINT | Enterprise object storage access address | Used to store large-volume documents such as submitted maintenance logs and road construction materials, adapting to batch file upload requirements. |
FE_DOMAIN | Highway maintenance review platform access domain name | Used to configure cross-domain access permissions for the frontend page, ensuring normal access by internal staff. |
ROOT_KEY | Random string of 32 or more characters | Used for interface authentication, ensuring the security of external calls to review applications. |
Three Common Mistakes
- Symptom: After container startup, port 3001 is accessible normally, but port 3000 fails to load the page. Cause: The
FE_DOMAINparameter is not configured correctly, causing the frontend page’s resource loading path to point to an incorrect address. - Symptom: Calling an interface fails to return response results for created review applications. Cause: The
ROOT_KEYparameter is not configured, or the passed secret key does not match, causing interface authentication to fail. - Symptom: When importing maintenance logs in batches, some documents have empty field extraction results. Cause: Parsing rules have not been adjusted for this category’s document format, causing the system to fail to recognize non-standard field content.
How to Verify Successful Configuration
- Run the
docker pscommand, confirm that all dependent service containers are in a running state, and verify that service addresses corresponding to parameters such asMONGODB_URIandREDIS_URLcan be connected normally. - Upload a maintenance plan document, check whether the system can correctly extract fields such as facility number and maintenance cycle, to verify that the document parsing configuration adapts to the current category’s document format.
- Call a public interface to test the authentication process, pass the correct
ROOT_KEYparameter, and confirm that the interface can normally return application configuration information. - Check system logs to confirm that there are no delayed errors in multi-source data synchronization tasks, verifying that the daily updated data link configuration is effective.
