What data for this category looks like
Data for this category comes from steel coil labels and quality certificates, press and feeder operation data, mold management systems, MES systems, coordinate measuring machine and fixture inspection data. Daily maintained documents include stamping work instructions, material utilization rate tables, mold inspection logs, first and last piece records, dimensional inspection reports, and mold change records. Data updates are triggered per coil of material, each production batch, or each mold change. A single document includes fields such as steel coil number, material grade, material thickness, mold number, mold change time, first piece dimensional deviation, and material utilization rate. Fields and content are dynamically adjusted alongside production batches.
What constraints these characteristics impose on HTTP interfaces and external systems
High-frequency, small-batch data updates require interfaces to support short-interval calls. This avoids data lag caused by production rhythm interruptions. Multiple heterogeneous data sources require interfaces to be compatible with return formats from different systems. Interfaces must support custom request headers and response parsing rules. Document changes for a single mold change or production batch trigger full or incremental synchronization. Interfaces must support filtering data by timestamp or batch ID. Errors in the production link have serious consequences. Interfaces must be configured with reasonable timeout and retry mechanisms. This prevents normal layout and mold change processes in the stamping workshop from being affected by external system exceptions. At the same time, dynamic adjustment of document fields requires interfaces to support variable parameter passing. This adapts to field requirements for different production scenarios.
How to set configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Fixed Bearer token format, with the value being the key assigned by the external system | Meets the identity verification requirements of external systems, prevents unauthorized access |
variables | Includes custom variables such as steel coil number, mold number, mold change time, with a range of 10–20 values | Adapts to the dynamic parameter transfer needs of stamping production scenarios |
responseData | Only extracts core fields such as material utilization rate, first piece dimensional deviation, number of mold changes | Reduces invalid data transmission and improves interface response efficiency |
| Request timeout | 30–60 seconds | Adapts to the production rhythm of the stamping workshop, avoids process interruptions caused by overly long interface waiting times |
| Retry count | 2–3 times | Addresses temporary fluctuations in external systems, ensures data synchronization success rate |
| Synchronization trigger rule | Triggered by mold change events, or executed every 15–30 minutes | Matches the data update rhythm of this category, balances real-time performance and system load |
Three common mistakes
- Interface calls return a 401 unauthorized error. This is caused by incorrect configuration of the
Authorizationparameter, and failure to use the Bearer token format required by the external system. - Synchronized stamping data fields are empty. This is caused by the
variablesparameter not including the dynamic fields required by the production scenario, and failure to correctly map core information from work instructions and material utilization rate tables. - External systems cannot establish a connection, with an error prompt indicating that the HTTP protocol is not supported. This is caused by not configuring the FastGPT service for HTTPS access, and instead using the default HTTP protocol port.
How to confirm the configuration is complete
- Call the configured interface, check if the returned
responseDataonly includes preset core fields, with no redundant non-production-related data. - Simulate a mold change event to trigger data synchronization, check if the external system can receive request parameters including the latest mold change time and mold number.
- View interface call logs, confirm that the
Authorizationparameter is correctly carried, and no unauthorized-related error messages appear. - Test access via the HTTPS protocol, confirm that a connection can be established normally, and meets the production environment's security specifications.
