What the Data for This Category Looks Like
The data source for general equipment yield rates primarily comes from real-time operation logs from equipment IoT platforms, publicly available industry benchmark operation reports, and internal enterprise operation and maintenance settlement data. Data is updated daily, with full aggregation of the previous day’s data completed in the early morning. It supports pulling data by equipment group or individual equipment. The standard structure of structured documents includes fields such as unique equipment identifier, deployment region, rated operating hours, actual operating hours, unit energy consumption cost, current period revenue, current period operation and maintenance cost, and current period net income. Units corresponding to the fields include hours, yuan, kilowatt-hours, units per hour, and others. Units for each field are fixed and cannot be modified arbitrarily.
Constraints on Form and Interaction
The multi-source nature of the data source requires the form to support multi-dimensional equipment filtering, to avoid errors from manual entry of equipment identifiers. The daily update rhythm requires the form’s date selection range to default to the previous day, to prevent users from selecting non-current-day data that does not meet daily report requirements. The structured fields and fixed units require the form to automatically adapt to unit formats, to reduce errors from manual entry. The batch pulling feature requires the form to support selecting multiple equipment or batch importing equipment IDs, to improve efficiency for multi-equipment report broadcasts. At the same time, the yield rate calculation logic is fixed, so the form must include built-in automatic calculation functions, to avoid deviations from manual calculations.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
form_max_selected_items | 100 units per request | Maximum batch pull limit for single general equipment daily reports, prevents single requests from exceeding interface bearing capacity |
form_default_date_range | [yesterday 00:00, yesterday 23:59] | Data update follows T+1 rhythm, default locks previous day's date range to reduce manual selection errors |
form_auto_calculate_fields | ["current period net income", "unit output yield rate"] | Yield rate calculation requires fixed formulas, automatic calculation avoids manual entry errors |
form_auto_append_unit | Enabled | Fields include multiple fixed units, automatic appending unifies input formats |
form_validate_timeout | 30 seconds | Batch equipment data verification requires a certain amount of time, timeout prevents form submission from getting stuck |
enable_batch_import | Enabled | Supports batch importing equipment ID lists, adapts to multi-equipment daily report broadcast needs |
The parameter values provided on this page are all common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: After the form input node’s default value references the global variable
global_device_data, the fields display as empty in preview. Cause: The data source binding for the global variable was not completed in the workflow’s preceding node, so the form cannot obtain the corresponding variable value when loading. - Phenomenon: When selecting multiple equipment in bulk, a
413 Request Entity Too Largeerror is returned after submission. Cause: Theform_max_selected_itemsconfiguration was not adjusted, so the number of selected equipment exceeds the maximum request length allowed by the interface. - Phenomenon: After manually entering values in the net income field of the form, a unit mismatch error occurs for the calculated yield rate result. Cause: The
form_auto_append_unitconfiguration was not enabled, so the manually entered unit does not match the field’s preset unit, preventing the system from recognizing the value type.
How to Confirm the Configuration is Complete
- Enter the form node’s configuration interface, check whether the value of
form_max_selected_itemsmatches the scale of equipment that needs to be reported currently. - Preview the form, confirm that the date picker loads the full time range of the previous day by default, and future dates cannot be selected.
- Manually enter values for revenue and operation and maintenance costs, check whether the calculation result for current period net income is automatically generated.
- Try importing a test file containing multiple equipment IDs, confirm that the form supports batch import and automatically verifies the equipment ID format.
