What the Data for This Category Looks Like
This category of data primarily comes from four sources: special equipment safety supervision systems, inspection and testing institution systems, user unit account books, and operator certificate databases. The update frequency is once per month. Daily documents include use registration certificates, periodic inspection reports, maintenance records, hidden danger rectification notices, accident reports, and operator certificates. Core fields cover device unique ID, inspection cycle, maintenance date, qualification validity period, hidden danger rectification status, and other items. The field structures of different documents vary, and some documents contain structured IDs and unstructured descriptive content.
Constraints Imposed by These Characteristics on the "Workflow Orchestration" Link
Because data sources are scattered and updated monthly, the workflow must be configured with a scheduled knowledge base synchronization trigger node to ensure retrieved content is up to date. Mixed storage of multiple document types requires the workflow to adapt to chunking logic for different formats, avoiding truncation of key fields such as device IDs and inspection cycles. The uniqueness requirement for core fields means the workflow must bind specific variables for precise matching. Time-consuming links such as qualification verification, inspection cycle checking, and rectification tracking must be split to reduce single-node execution pressure. The high-risk nature of supervision scenarios requires the workflow to add verification links to prevent incorrect data from triggering subsequent processes.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Chunk Length | 800–1200 characters | Adapts to the paragraph length of special equipment-related documents, avoiding truncation of key fields such as device IDs and inspection cycles |
| Overlap Length | 100–200 characters | Retains associated information such as device IDs and inspection cycles across chunks, ensuring completeness of cross-chunk retrieval |
| Single Search Limit | Top 6 entries | Covers multiple types of associated documents for a single device, including registration certificates, inspection reports, maintenance records, and other items |
| Timeout Setting | 60 seconds | Adapts to the hardware performance of local deployments, avoiding lag caused by long queries or multi-document retrieval |
variables | Bind device ID and inspection cycle fields | Enables precise matching of core query dimensions in supervision scenarios, improving the relevance of retrieval results |
| Workflow Node Trigger | Trigger via keyword matching | Corresponds to the node scheduling logic of nodeId, enabling step-by-step execution of question classification and AI Q&A links, avoiding task confusion |
Three Common Misconfigurations
- Phenomenon: An API call returns that the
modelparameter is unrecognized or empty. Cause: No model binding parameter is configured invariables, causing the workflow to fail to clearly define the task type for question classification or AI Q&A. - Phenomenon: The interface displays a 504 request timeout status code after workflow execution. Cause: No reasonable timeout time is set, or no chunking logic for long documents is split, causing retrieval time to exceed system thresholds.
- Phenomenon: Retrieval results only return a single type of document, failing to cover all associated information such as maintenance and inspection records. Cause: The single search limit is set too low, failing to match multiple types of special equipment-related documents.
How to Verify Proper Configuration
- Manually enter a query that includes a specific device ID, check whether the returned results include associated information such as the corresponding device's use registration certificate and periodic inspection report.
- Call the API to test the workflow, confirm that the
modelparameter is correctly passed, and that the returned results conform to the preset question classification or Q&A logic. - View the workflow logs in FastGPT v4.17.0, confirm that the device ID and inspection cycle fields in
variablesare correctly extracted and used for retrieval. - Simulate a monthly update scenario, upload the latest inspection report document, and test whether the workflow can load and retrieve the updated content.
