What this category of data looks like
Nuclear power operations business process data primarily comes from nuclear power production management systems, equipment ledger databases, and on-site operation logs. Full data synchronization and updates are completed every day at midnight. Each individual business process document uses a structured table format, containing fields such as unique process identifier, node name, approval role, prerequisite node, trigger condition, and response time limit. The process ID is a 12-character combination of uppercase letters and numbers. The response time limit field uses minutes as its unit. The equipment association field uses a 16-digit equipment code.
What constraints do these characteristics impose on the "workflow orchestration" link
The structured data characteristics of nuclear power operations require that workflow orchestration strictly follow fixed field mapping rules. Do not arbitrarily adjust field order or add undefined new fields. The daily synchronization update rhythm requires that database query nodes use a fixed scheduled trigger cycle, to avoid high-frequency pulling that occupies system resources. The unique process ID requires that variables in the workflow bind the process ID as a query condition, to prevent cross-process data confusion. The minute-based response time limit requires that timeout nodes use minute-based thresholds, to align with nuclear power business approval time requirements. The 16-digit equipment code format requires that input nodes add format verification rules, to block illegal characters from entering the workflow.
How to set the configurations
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
variables | Bind process ID and equipment code | Accurately match the unique data identifiers of nuclear power business, avoid confusion of cross-process data |
| Form configuration default value | Preset to the current process's nodeId | Automatically bring in the current process's node identifier, reduce manual input errors |
| Database query node trigger cycle | 2:00 AM every day | Match the daily synchronization update rhythm of nuclear power systems, avoid high-frequency pulling |
| Loop node concurrency upper limit | 3 times/second | Adapt to the low-concurrency approval scenario of nuclear power business, prevent system current limiting from being triggered |
| Timeout threshold configuration | 30 minutes | Match the standard response time limit of nuclear power business approval, conform to industry conventional requirements |
| Feishu Webhook message splicing | Only splice the first 5 results of the loop node | Avoid messages being too long and exceeding platform transmission limits, adapt to the message transmission requirements of nuclear power sites |
Three Common Misconfigurations
- Phenomenon: After configuring default values for form input nodes, the bound variable values cannot be obtained during runtime, and the interface displays empty fields. Cause:
variablesare not correctly bound to the default value field of the form configuration, only fixed static text is filled in. - Phenomenon: After the database query node returns JSON format results, downstream nodes cannot directly read the field content. Cause: Field mapping is not completed for the structured data of nuclear power business, and direct use of original query results leads to field recognition failure.
- Phenomenon: When calling MCP from a loop node, the returned result is none under high concurrency. Cause: A reasonable concurrency upper limit is not set, which exceeds the node concurrency bearing threshold of FastGPT v4.17.0, resulting in requests being discarded.
How to Confirm Proper Configuration
- Manually trigger a test process, check whether the default value of the form node automatically brings in the current process identifier.
- Run the database query node, verify that the returned result fields completely match the preset nuclear power business data fields.
- Simulate concurrent calls that conform to the business scenario, check whether the returned results of the loop node are all valid content.
- Configure the Feishu Webhook node, send the spliced message, and verify that the message content meets the business transmission requirements.
