What the data for this category looks like
Data related to water treatment yield rates comes from online water quality monitoring sensors, water utility SCADA systems, project operation and maintenance logs, and third-party environmental data service providers. Data updates follow a daily cadence. Some real-time monitoring nodes refresh data every hour. The structure of individual data records includes: project code, affiliated region, operation period, influent pollutant concentration, effluent compliance rate, chemical cost, energy consumption cost, reclaimed water sales revenue, subsidy revenue, daily net profit, and cumulative annualized yield rate. Field formats and units are as follows:
- Project code: string
- Operation period: date-time format
- Pollutant concentration: milligrams per liter
- Cost and revenue: yuan
- Compliance rate and yield rate: expressed as decimals
What constraints these characteristics impose on forms and interactions
Dispersed data sources require forms to support multi-data source access configuration, with separate interaction logic for API integration and local file import. The combined daily update and real-time refresh cadence requires forms to support two trigger modes: scheduled pulling and manual supplementary entry. It also requires configuring a data time window to prevent pulling invalid data that is too early or too late. The large number of fields with clear unit and format requirements requires forms to configure field validation rules to block invalid numerical and format inputs. Some fields have linked calculation relationships, requiring forms to configure automatic field linkage logic. When cost or revenue fields are updated, net profit and annualized yield rate are automatically calculated. The daily report broadcast scenario also requires forms to support batch import of multiple sets of daily monitoring data, as well as single-data editing and export configuration.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
workflow_trigger_mode | Scheduled trigger + Manual trigger | Daily water treatment yield rate reports must be generated on a fixed daily basis, while supporting temporary supplementary entry of historical operation and maintenance data |
form_field_validation | Configure numerical range and format validation | Water treatment data fields must comply with operation and maintenance specifications to avoid invalid inputs disrupting calculation logic |
data_source_sync_interval | 3600 seconds | Real-time monitoring nodes refresh data every hour. This interval ensures the timeliness of data pulled for daily reports |
batch_import_max_rows | 50 rows | The volume of monitoring data for a single project group in a single daily report usually does not exceed 50 sets, preventing import timeouts |
voice_input_enable | Disabled | Water treatment data has many fields and requires precise numerical values. Voice input is prone to accuracy errors |
workflow_nested_dialog_display | Globally hidden | Daily report broadcast workflows are usually embedded as nested nodes in parent workflows, requiring unified control of dialog display status |
The parameter values provided on this page are all conventional recommendations used as 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 conduct actual testing on your own samples before finalizing settings.
Three common mistakes
- Symptom: The form node dialog always displays when nested in a parent workflow. Cause: The
workflow_nested_dialog_displayparameter is not configured, and the default dialog display logic for nested nodes is retained. - Symptom: The global variable option in the prompt editor only displays 2 options in version 4.9.10. Cause: This version optimized the global variable loading logic. The global variable synchronization switch must be manually enabled to load all variables.
- Symptom: A 504 status code is returned when batch importing data. Cause: The
batch_import_max_rowsconfiguration value is too large, exceeding the server request timeout limit.
How to confirm the configuration is complete
- Manually trigger the workflow, check if the field validation rules of the form node block numerical inputs that exceed reasonable ranges. Reasonable ranges must be calibrated based on actual project operation and maintenance data.
- Configure a scheduled trigger task, wait for the specified time, and check if water treatment monitoring data matching the operation period is automatically pulled.
- Embed this workflow in a parent workflow, check if the form node dialog is hidden as expected.
- Enable voice input functionality, check if the supported browser list includes the currently used browser. The supported list must be adjusted based on the actual deployment environment.
