What the data for this category looks like
Business data sources for coal mining production include downhole personnel positioning base stations, gas concentration sensors, equipment operation and maintenance ledger systems, mine-level attendance management systems, and internal office OA platforms. Real-time sensor data such as personnel location and gas concentration updates every second. Equipment ledgers and attendance data update daily. Office workflow data updates when submitted. The data format is standardized JSON. Core fields include device ID, location coordinates (unit: meters), sensor values (such as gas concentration %LEL), employee ID, work order status, and others. There are significant differences in field types.
What constraints these characteristics impose on HTTP interfaces and external systems
The second-level updates of real-time sensor data require interfaces to support high-frequency requests. Timeout settings must adapt to short response cycles. The type differences and nested structures of structured JSON fields require interface requests to precisely limit scope. Otherwise, returned data redundancy will exceed processing capacity. Most coal mining production environments use closed intranets. External system access requires exclusive authentication tokens, and must adapt to verification rules for intranet self-signed SSL certificates. Batched updates of office workflow and equipment data require interfaces to support incremental pulling by timestamp, to avoid repeatedly obtaining full data sets.
How to Set Configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Request timeout | 5–10 seconds | Matches the high-frequency update rhythm of coal mining sensor data, avoids waiting long for invalid responses |
Authorization | Bearer example value | Coal mining intranet systems use exclusive token authentication to prevent unauthorized access |
variables | Pass in the format {"targetType": "personnel", "scope": "underground"} | Limits request target type and scope, reduces returned data volume |
responseData | Extract content under the $.result.sensorData path | Adapts to the nested JSON structure of coal mining structured sensor data |
| SSL certificate verification | Disabled | Most coal mining intranets use self-signed SSL certificates; enabling verification will cause connection failures |
Three Common Misconfigurations
- Phenomenon: Interface calls return "Message receiving address verification failed", with status code 403 or connection timeout. Cause: The coal mining intranet system has not opened public network access permissions, or SSL certificate verification rules are not configured correctly.
- Phenomenon: Core fields are empty after
responseDataparsing. Cause: The actual nested path of coal mining data is not matched, and general parsing rules are used incorrectly. - Phenomenon: Obvious interface response delay occurs after high-frequency requests. Cause: The request scope is not limited via
variables, and returned redundant data exceeds the interface's carrying capacity.
How to Confirm Configuration is Complete
- Initiate a single test request, verify that the field range of the returned data matches the preset
variablesparameter. - Check interface call logs, confirm that the
Authorizationtoken is correctly carried and authentication is passed. - Verify that the content extracted by
responseDataincludes the core fields required for business, with no additional redundant data. - Simulate high-frequency requests, confirm that the interface response duration meets the preset timeout threshold settings.
