What the Data for This Category Looks Like
Document and material data for urban public transit primarily comes from internal operation systems, station management ledgers, safety inspection archives, and publicly disclosed documents. Specific data sources include daily generated shift schedules, monthly revenue reports, quarterly safety rectification notices, and temporary route adjustment announcements. Most documents are structured tables and standard official documents, with fixed fields such as route number, operating mileage, passenger trips, and rectification deadline. Units include kilometers, trips, yuan, and days. Data update frequencies vary widely: operation documents are updated daily, announcements are released on demand, and archives are filed quarterly.
What Constraints These Characteristics Impose on Deployment and Upgrade
The characteristics of urban public transit document data impose clear constraints on the deployment and upgrade phase. A high proportion of structured documents requires configuring table parsing preprocessing during deployment, to avoid field loss caused by unstructured splitting. Wide variation in data update frequencies means daily updated operation documents need incremental sync tasks, to avoid excessive system resource usage from full synchronization. Many fixed fields with clear units require pre-binding field mapping rules during knowledge base configuration, to prevent field misalignment during import. Some operation documents involve internal management information, so tiered storage access permissions must be configured during deployment to ensure data security.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 concurrent connections | Large single batch import volume for urban public transit documents, requires adapting to high-concurrency database connection needs |
MONGODB_URI | Internal network connection address for local private deployment | Stores unstructured documents such as operation archives and rectification records; internal network access ensures data security |
REDIS_URL | 1000 MB memory configuration | Caches frequently queried route data and real-time scheduling information to reduce access pressure on the core database |
STORAGE_S3_ENDPOINT | Internal network access address for local object storage | Stores large-volume documents such as monthly ledgers and quarterly reports imported in batches, adapting to bulk data storage requirements |
ROOT_KEY | Custom 32-character random string | Configures system administrator access permissions to avoid security risks from default keys |
FE_DOMAIN | Local IP:3000 | Access the system frontend via internal network address in private deployment scenarios, no public domain name required |
Three Common Misconfigurations
- A
docker pullimage timeout or500 Internal Server Erroroccurs during deployment. This is caused by failure to configure an internal image source or disable public network proxy, resulting in inability to access the official image repository. - Generated public transit documents only output in Chinese, even if the prompt and knowledge base content are in English. This is caused by failure to specify multilingual model output rules in system configuration, resulting in model invocation parameters not taking effect.
- Vector database connection fails, returning a
503 Service Unavailablestatus code. This is caused by incorrect configuration of internal network proxy rules, resulting in inability to access the specified vector database service node.
How to Confirm Proper Configuration
- Run the
docker pscommand to confirm all FastGPT-related containers are running, with no abnormal exit records. - Upload a public transit monthly revenue report to the knowledge base, and check that the parsed fields match the preset mapping rules, with no missing or misaligned fields.
- Initiate a document generation test, input a shift schedule generation requirement, and confirm the generated result includes required fields such as route number and shift count, with format conforming to standard official document requirements.
- Access the internal network address configured for
FE_DOMAIN, and confirm the system login page loads normally, with administrator permissions enabled properly.
