What the Data for This Category Looks Like
Production data for the pulp and paper industry has characteristics of multiple sources and varying update rhythms. Data sources include wood pulp and waste paper raw material batch archives, paper machine DCS/QCS control systems, online quality testing equipment, laboratory test reports, and energy and water treatment systems. Update rhythms fall into three categories: online detection data is updated in real time, team operation records are archived per shift, and finished roll quality archives are generated per roll. Document types cover pulp preparation operation sheets, beating process ledgers, paper machine operation reports, online quality trend charts, and sheet break and roll change records. Fields include pulp ratio parameters, web grammage, thickness values, sheet break frequency, and similar items.
What Constraints Do These Characteristics Impose on Workflow Orchestration
The multi-source data characteristics of pulp and paper production impose multiple constraints on workflow orchestration. First, dispersed data sources require workflows to support parallel pulling of different document types across multiple nodes, to avoid single-node blocking of production processes. Second, data with different update rhythms needs matching trigger rules: real-time data binds immediate audit nodes, and periodic data configures scheduled trigger links. Third, full-link traceability requirements require workflow variables to associate raw material batches, paper machine numbers, and finished roll numbers, to ensure complete production information is traceable for each audit step. Fourth, diverse document formats require workflows to adapt to different parsing rules, to ensure all types of data can be read and analyzed normally.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind three-level fields: raw material batch, paper machine number, finished roll number | Matches the full-link traceability logic of pulp and paper production |
| Timeout Threshold | 300-600 seconds | Adapts to the pull delay requirements of real-time online data |
| Number of Parallel Nodes | 4 parallel nodes | Balances resource usage and execution efficiency for pulling multiple data sources |
| File Storage Path | /paper_mill/[raw material batch]/[roll number]/ | Matches the batch archiving and traceability requirements of pulp and paper production |
| Trigger Condition | Triggered when a sheet break record is generated or when changing product per shift | Covers core quality anomaly and periodic audit scenarios |
nodeId | Assigned by data source, e.g., DCS data node ID is dcs_001 | Quickly locates workflow nodes for different data sources |
Three Common Configuration Mistakes
Mistake 1
- Phenomenon: Pulp preparation sheets and online quality curves uploaded in the workflow cannot find their corresponding storage paths. Logs show the file path field is empty.
- Cause: The file path binding rule in
variablesis not configured, causing the system to fail to automatically generate the archiving path.
Mistake 2
- Phenomenon: The front-end interface freezes when selecting variable values, and there is no response when dragging nodes or deleting variables.
- Cause: Too many unrelated redundant fields are configured in
variables, leading to excessive front-end rendering load.
Mistake 3
- Phenomenon: In the workflow case teaching document, the 16-document comparison helper does not display copyable configuration source code, making direct import of the configuration impossible.
- Cause: The source code export option is not enabled in the workflow editing interface, or the case document has not been updated with the configuration template synchronously.
How to Confirm Proper Configuration
- Enter the workflow editing interface of FastGPT v4.17.0, check the
variablesconfiguration item, and confirm that the three-level fields of raw material batch, paper machine number, and finished roll number are bound. - Upload a pulp preparation sheet document, and check whether the automatically generated storage path complies with the preset archiving rules.
- Simulate generating a sheet break record to trigger workflow operation, and check whether the node execution logs normally pull documents from the corresponding data source.
- Export the workflow configuration, and confirm that complete configuration source code can be obtained for subsequent reuse.
