What This Category of Data Looks Like
Data for this category comes from EAM/CMMS systems, equipment sensor collection terminals, operator spot check records, historical repair work orders, spare parts inventory ledgers, and statutory inspection files for special equipment. Data update cycles cover shift-based spot check submissions, daily/weekly maintenance plan distribution, and immediate entry when a fault occurs. Daily documents include standardized equipment ledgers (with equipment number and installation location fields), spot check forms (with point number and detection value unit fields), repair work orders (with fault code and processing duration fields), spare parts lists (with model and inventory quantity fields), and special equipment inspection records. Data structure is adjusted dynamically based on business scenarios.
Constraints Imposed on Workflow Orchestration
Multi-source heterogeneous data sources require workflows to support calling variables from different data sources simultaneously. This avoids data limitations from single nodes. Business requirements with varying update frequencies require workflows to be configured with multiple trigger conditions. This balances scheduled spot checks and immediate fault response. Structural differences across multi-field documents such as equipment ledgers and spot check forms require workflows to use node parameters to distinguish data reading rules for different sources. Repair windows must comply with production scheduling constraints. This requires workflows to integrate scheduling-related variable judgments. Conflicts with production plans are avoided. Severe consequences such as unplanned downtime require workflows to be configured with clear failure handling nodes. This ensures timely fault response. In FastGPT v4.17.0, the configuration logic for failure handling nodes has been optimized. This meets the high reliability requirements of this category.
Configuration Recommendations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Define equipment number, check point, and spare parts inventory threshold by data source | Matches the multi-field structure of equipment spot check data, distinguishes field rules across different data sources such as ledgers, sensors, and work orders |
nodeId | Assign unique node IDs for equipment ledgers, spot check forms, and repair work orders separately | Differentiates multi-data-source call nodes, avoids parameter confusion during workflow execution |
| Trigger conditions | Trigger on a scheduled basis per spot check cycle, and trigger when a fault occurs | Matches shift/daily/weekly update frequencies and business requirements for immediate fault response |
| Node timeout | 600 seconds | Adapts to typical response durations for equipment sensor data pulling and work order queries |
| Batch processing limit | Top 20 entries | Limits the number of spot check records processed in a single workflow run, prevents system resource overload |
| Maximum single data length | 1000 characters | Adapts to typical field lengths of spot check forms, prevents data overflow |
| Failure retry count | 2 times | Addresses network fluctuations or temporary interface call failures, ensures rapid recovery in repair scenarios |
Three Common Configuration Mistakes
- Workflows cannot parse HTTP returned image file streams. Logs show file fields are empty. The cause is failure to configure a file stream parsing node, and only reading interface return content in text format.
- Workflows cannot call custom environment variables, and cannot read spare parts inventory thresholds configured during deployment. The cause is failure to enable environment variable call permissions in workflow configuration, and failure to correctly reference environment variable parameters.
- Loop body execution returns empty results, and loop index shows null. The cause is failure to correctly bind the batch spot check record data source field in loop configuration. This leads to no valid execution objects for the loop.
How to Verify Correct Configuration
- Manually trigger a workflow test, check whether the equipment number defined in
variablescorrectly loads corresponding ledger data. - Simulate a fault trigger scenario, verify whether the workflow starts per configured rules and calls the repair work order data source.
- View workflow execution logs, confirm that the failure retry mechanism triggers normally when simulating interface exceptions.
- Run a batch spot check test, confirm that the number of returned records matches the set batch processing limit.
