What this category of data looks like
Patrol monitoring and alarm judgment data for multi-source monitoring data fusion comes from on-site IoT sensing devices, video surveillance systems, data reported via operation and maintenance patrol apps, and historical alarm databases. Sensing device data updates at a second-to-minute interval. Manually reported patrol logs and work order data updates at an hour-to-day interval. Each data entry includes a unique device identifier, collection timestamp, monitoring indicator name, indicator value, indicator unit, data source channel, and associated patrol task ID. Fields include device number, collection timestamp, indicator name, indicator value, and other relevant fields. Units include common monitoring indicator units such as ℃, Pa, mm/s, %, and other standard units.
Constraints for HTTP Interfaces and External Systems
Multi-source monitoring data has low-latency update requirements. HTTP interface response times must match business real-time needs to avoid missing alarm trigger windows. Inconsistent field naming across multiple data sources means interfaces must support flexible custom field mapping configurations. This avoids compatibility issues caused by hardcoding. Different devices use different reporting formats. Interfaces must support multiple request body structures and data encoding methods. As the number of patrol devices increases, interfaces must support batch pulling or paginated requests. This balances data transmission efficiency and system load. Alarm judgment requires real-time association of multi-source data. Interfaces must guarantee full data pulling and parsing efficiency for single requests.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer {custom secret} | Complies with general HTTP interface security specifications to implement access control for cross-system access |
| Interface timeout | 5-10 seconds | Matches the second-to-minute update rhythm of patrol monitoring data, to avoid delayed alarm triggers |
| Field mapping rules | Preset mappings by device type | Resolves inconsistent field naming across multi-source data, adapts to data formats from different sources |
| Batch request limit | Top 50 entries | Balances data transmission efficiency and interface load, avoids timeouts caused by excessive data in a single request |
responseData parsing path | data array under root node | Adapts to standard return structures of most multi-source data interfaces, quickly extracts valid monitoring data |
variables input parameters | Device ID list, alarm threshold range | Used to limit the target data range pulled by the interface, reduces calculation volume for subsequent alarm judgment |
Three common configuration mistakes
- Issue: After configuring an external callback interface, alarm push fails, or Feishu webhook push has no response. Cause: Correct callback address and signature verification rules were not added to the interface configuration, so external systems cannot complete authentication and data reception.
- Issue: After calling the FastGPT API, the returned AI chat reply content has variable value superposition, for example, the result from the previous request is carried into the current result. Cause: Context variables for each request were not properly isolated in the
variablesparameter, so the session state was not reset, and context information from previous requests remains. - Issue: When deploying locally, data cannot be retrieved solely via the external HTTP interface, and the built-in local database is still used. Cause: The default configuration of the built-in data source was not disabled, and only external interface call permissions were enabled, so the system attempts to read local data at the same time.
How to confirm the configuration is correct
- Send a test request with the
variablesparameter, check if the fields returned inresponseDatamatch the preset mapping rules. - Simulate multiple batches of device data requests, observe if the interface response time meets business real-time requirements.
- Send 3 consecutive requests with different
variablesparameters, confirm that no context residue or variable superposition appears in each returned result. - Configure an external callback address, verify that data is properly pushed to the specified external system after an alarm is triggered.
