What This Category of Data Looks Like
The daily documents for this category include foundry process cards, batching lists, heat records, mold history records, first article inspection records, material test reports, and nonconforming product review forms. Data sources cover ERP material master data, melting furnaces and thermometers, spectrometers, MES heat records, mold management systems, customer drawings, and technical specifications. Data update frequency is per heat, per batch, or daily. Core business fields include alloy grade, heat number, melting temperature, mold cycle count, and others. Field formats across different documents must match the unified standards for foundry processes.
Constraints Imposed by These Characteristics on HTTP Interfaces and External Systems
High-frequency real-time data updates for this category require interfaces to support short-interval calls, to avoid disrupting on-site inspection workflows due to data delays. Multiple heterogeneous data sources require interfaces to adapt to the return formats of different systems, and pre-configured mapping of business fields must be completed. Compliance requirements for core business fields mean interfaces must include basic validation logic to reduce invalid calls. Additionally, internal defect tracing requires associating multi-dimensional data such as heat numbers and mold cycle counts, so interfaces must support combined multi-parameter queries to ensure accurate matching of returned results.
How to Set the Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {FastGPT-assigned API key} | Follow HTTP interface authentication specifications to ensure permission security for multi-system integration, and meet the interface requirements of FastGPT v4.17.0 |
variables | {"炉次号": "{{input.炉次号}}", "合金牌号": "{{input.合金牌号}}"} | Pass core business fields for foundry scenarios, match the query logic for equipment inspection and maintenance, and enable accurate document recall |
responseData | Return structured Q&A results + associated document ID list | Filter redundant data, adapt to the fast reading requirements of workshop terminals, and simplify on-site data display |
| Interface timeout period | 30–60 seconds | Cover the typical time required for melting parameter analysis and document retrieval, to avoid call failures caused by delayed return of equipment data |
| Field validation rules | Validate that heat numbers and alloy grades conform to foundry process specifications | Filter invalid queries in advance, reduce invalid interface calls, and lower system load |
| Retry trigger conditions | Status codes 429, 500, or request timeout | Automatically recover from high-frequency call rate limiting and temporary system failures, to ensure continuity of inspection workflows |
Three Common Misconfigurations
- A 400 invalid image response is returned when calling the multimodal inspection interface. Cause: The standardized image format generated by thermometers or spectrometers is not passed as required for foundry scenarios, or the image size exceeds the interface limits.
- A format error is returned by the interface when uploading foundry process documents. Cause: The specified file format is not used as required, or the file size exceeds the interface limits, which does not meet the upload specifications for foundry scenario documents.
- Only the first node is triggered after the workflow is connected to an external system. Cause: The
variablesparameter is not correctly passed in the interface configuration, causing subsequent nodes to fail to obtain business context and complete workflow linkage.
How to Confirm Successful Configuration
- Send a test request containing valid heat numbers and alloy grades, and check that the returned results include matching foundry process cards and associated heat record IDs.
- Simulate high-frequency calls, and check that the interface does not trigger rate limiting errors and the retry mechanism works properly.
- View interface logs to confirm that the
Authorizationparameter is correctly carried and the business fields passed by thevariablesparameter have compliant formats. - Connect to workshop terminal equipment, and verify that the returned structured data can be directly used for on-site queries for equipment inspection and maintenance.
