What this category of data looks like
This category of data covers the entire production process of automotive body panel, home appliance sheet metal, and hardware stamping workshops. Daily documents include stamping operation instructions, material utilization rate sheets, mold inspection sheets, first and last piece records, dimensional inspection reports, and mold change records. Data sources include steel coil labels and quality certificates, real-time operating data of stamping presses and feeders, mold management systems, MES systems, and coordinate measuring machine or fixture inspection data. Data updates are triggered per coil of material, per batch of materials, and each mold change. Document fields include material batch number, mold number, operating parameters, and measured dimensional values, with units including millimeters, Newtons, tons, and others.
What constraints these characteristics impose on HTTP interfaces and external systems
This category of data has high update frequency and dispersed sources, requiring HTTP interfaces to support real-time pulling and batch synchronization of multi-source data. Different external systems have varying data field formats, so interfaces must support parsing logic for multiple return structures. Updates triggered by each mold change or coil of material require interfaces to have fast response capabilities to avoid disrupting production tempo. Equipment inspection and maintenance Q&A needs to associate historical data for specific molds and material batches. Interface requests must carry precise parameters such as mold number and material batch number to ensure returned data matches the business scenario.
Configuration guidelines
These configurations apply to FastGPT v4.17.0:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {external system API key} | Complies with external system identity authentication specifications to ensure legitimacy of interface calls |
variables | Pass mold number and material batch number as custom variables | Matches precise data query requirements in stamping scenarios to narrow the scope of returned data |
| Interface timeout setting | 30–60 seconds | Matches the update cycle of stamping equipment data to avoid response delays |
| Maximum number of returned entries per single request | Top 3 | Equipment inspection and maintenance Q&A only requires the latest historical records for reference, avoiding interference from redundant information |
responseData | Only retain mold status, operating parameters, and maintenance record fields | Streamlines returned content to reduce resource overhead for context processing |
| Interface call frequency limit | 1 time per 10 seconds | Matches the update rhythm of stamping workshop equipment data to avoid exceeding external system call quotas |
Three common mistakes
- Phenomenon: External system interface calls return a 401 unauthorized error. Cause: The
Authorizationparameter is not configured correctly, and no identity verification token meeting external system requirements is carried. - Phenomenon: After local deployment, the front-end access address cannot be switched to HTTPS, resulting in cross-domain errors during interface calls. Cause: FastGPT front-end HTTPS related settings are not configured correctly, and the HTTP protocol is not switched to HTTPS.
- Phenomenon: Interface returned data fields do not match business requirements. Cause: Precise parameters such as mold number and material batch number are not passed via
variables, causing the external system to return irrelevant historical data.
How to confirm configuration is complete
- Send a test request to the configured external system interface, and check if
responseDataincludes expected fields such as mold status, operating parameters, and maintenance records. - Check if the format of the
Authorizationparameter meets the identity authentication requirements of the external system, with no spelling or format errors. - Simulate a mold change scenario, pass a new mold number and material batch number, and confirm that the interface returned data matches the relevant information of the current batch.
- Call the interface 10 times consecutively to confirm there are no timeout or current limit errors, verifying that the call frequency limit setting is effective.
