What the data for this category looks like
Core data for construction machinery yield rates comes from operation duration data collected by equipment IoT terminals, and financial accounting data from enterprise ERP systems. Full daily summary for the previous calendar day is completed every early morning, generating standardized daily report documents. Documents use JSON format, with fields including equipment_id, work_hours, total_revenue, maintenance_cost, net_profit, and stat_date. The unit of work_hours is hours. All monetary fields use Chinese Yuan as the unit. stat_date uses standard date format.
What constraints do these characteristics impose on the HTTP Interfaces and External Systems workflow
Multi-source data collection requires the interface to support cross-system authentication and data merging logic. Compatible authentication parameters for different data sources must be configured. The fixed daily update schedule requires the interface’s cache validity period to match the data update cycle, to avoid returning expired data. The multi-field, multi-unit structure requires the interface to include built-in field format validation and unit consistency validation, to block non-compliant requests. Additionally, for scenarios with large single-batch device data volumes, the interface must support pagination query parameters, to prevent transmission timeouts or slow responses caused by overly large single-returned data volumes.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
SYNC_DATA_TIMEOUT | 900 seconds | Adapts to the summary time of multi-source IoT and financial data, prevents single synchronization timeout interruptions |
REQUIRED_REQUEST_FIELDS | ["stat_date", "equipment_id"] | Ensures the interface only returns yield data for the specified statistical date and equipment, avoids invalid requests |
DAILY_SYNC_CRON | 0 0 3 * * * | Matches the industry’s conventional data update schedule, triggers full data synchronization at 3 AM daily |
RESPONSE_DATA_UNIT | Unified output as Chinese Yuan per hour | Standardizes returned data units, reduces format processing costs for callers |
MAX_RESPONSE_SIZE | 10 MB | Limits the amount of data returned in a single interface call, prevents network transmission timeouts |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- An interface returns
400 Bad Requestwith a prompt indicating missing required parameters. The cause is failure to pass thestat_dateorequipment_idparameters as required by the configuration, so the interface cannot locate the target daily report data. - An interface call times out, returning a
504 Gateway Timeoutstatus code. The cause is failure to adjust theSYNC_DATA_TIMEOUTconfiguration; the default timeout period is insufficient to complete multi-source data summary and retrieval. - Frequent connection errors occur when calling external interfaces from a locally deployed FastGPT. The cause is failure to configure the
API_ALLOWED_IPSparameter, and the IP range of the locally deployed node was not added to the whitelist, so network access is blocked.
How to Confirm the Configuration Is Complete
- Initiate a test request carrying the
stat_dateandequipment_idparameters, verify that the returned JSON document includes all fields required by the configuration. - Review interface synchronization logs to confirm that the scheduled daily synchronization task runs automatically during the configured time window, with no timeout or error records.
- Compare the monetary and duration values returned by the interface with the statistical results from the enterprise’s internal systems, confirm that units and formats meet preset requirements.
- Test a query request involving multiple devices, verify that pagination parameters take effect, and returned data is complete and not truncated.
