What data for this category looks like
This category of data typically comes from highway maintenance management systems, bridge and tunnel monitoring systems, road patrol systems, and traffic flow monitoring data, with a daily update frequency. Common documents involved include maintenance plans, patrol logs, defect disposal records, road construction permits, and road property damage compensation forms. Document fields include facility ID, defect type, disposal deadline, compensation amount, construction scope, and other items. Units include kilometers, square meters, cubic meters, yuan, and others. Service entities are mostly transportation bureaus, highway development centers, maintenance units, and road law enforcement agencies. Core data is generated around the maintenance status of road facilities and road property management workflows. Unlike similar transportation categories, this category excludes business access processes for transportation enterprises.
What constraints these characteristics impose on the deployment and upgrade phase
This category has scattered data sources and a daily update frequency. Deployments must adapt to multi-system data integration logic, and require stable database and cache connection configurations to support high-frequency data synchronization. Daily document formats vary, including plain text logs, form-based disposal records, image-based patrol records, and other types. Administrators must verify storage configurations adapt to different document sizes and batch processing requirements during deployment. Core workflows focus on road facility status and road-related business. Post-deployment, teams must ensure real-time data performance. During upgrades, teams must maintain compatibility with interface specifications of existing business systems to avoid disrupting normal operation of work consultation and reply services. At the same time, data anomalies or workflow errors may lead to road safety risks or financial disputes. Developers must configure error alerts and retry mechanisms during deployment. Before upgrades, teams must complete full workflow verification.
How to set configurations
This guide uses FastGPT v4.17.0 for all configurations.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 10–15 | Supports daily high-frequency queries of patrol logs, disposal records, and other data, to avoid service disruption from exhausted connection limits |
REDIS_URL | redis://localhost:6379/0 | Accelerates retrieval response for defect information and road-related permits, adapting to the high-frequency access rhythm of daily data updates |
STORAGE_S3_ENDPOINT | Internal institutional object storage access address | Stores maintenance plans and image-based patrol data, adapting to batch storage requirements for large-volume documents |
FE_DOMAIN | Internal institutional office domain name | Ensures the work consultation interface is only accessible via internal networks, complying with sensitive data management requirements |
FILE_TOKEN_KEY | Calibrated via actual testing | Generates document access tokens to control access permissions for sensitive documents such as road construction permits and road property damage compensation forms |
Three common mistakes
- Symptom: An error occurs during image build stating that the rehype-raw module cannot be found, even though the installation command has been run. Cause: Dependency installation did not lock version numbers, or an incompatible package manager cache was used.
- Symptom: A client-side error appears when opening the workflow editing interface after an air-gapped deployment. Cause: Offline dependency packages were not configured during deployment, or the external dependency pull logic was not disabled.
- Symptom: Docker containers continuously restart and cannot be accessed after startup. Cause: Database connection configuration is incorrect, making it impossible to connect to the data source of the highway maintenance management system.
How to confirm configurations are correct
- Run the database connection test command to verify that the
DB_MAX_LINKconfiguration supports batch document indexing tasks. - Upload a defect disposal record document to check if the storage service configured via
STORAGE_S3_ENDPOINTcan properly save and read the document. - Access the domain name configured via
FE_DOMAINto confirm that the work consultation and reply interface loads normally on the internal office network. - Simulate a daily data synchronization task to check if the cache service configured via
REDIS_URLcan properly cache retrieval results.
