What the data for this category looks like
Data sources for production ledgers in transformer and high-voltage electrical manufacturing include design BOM, silicon steel sheet and insulating material inventory data, vacuum drying equipment operation logs, oil test reports, and partial discharge and withstand voltage test data from high-voltage test stations. Data update frequency is once per device before shipment, with synchronized updates when each batch of raw materials is put into storage. Daily generated ledger documents include winding and core assembly records, vacuum drying records, insulating oil test reports, partial discharge and withstand voltage test reports, and equipment nameplate parameter tables. Fields include insulation moisture content, partial discharge value, withstand voltage rating, rated voltage, and more. Corresponding units are ppm, pC, kV, kV, and others.
What constraints these characteristics impose on HTTP interfaces and external systems
Data sources for this category are scattered, covering industrial equipment, test reports, and test records. HTTP interfaces must support pulling structured and unstructured data from multiple data sources. Ledger updates for a single device occur frequently and require precise matching of device IDs. Interfaces must support parameter designs for queries by batch or device serial number. Documents include large-volume test reports, so interfaces must adapt to file transfer or file URL return formats. Data involves core parameters such as insulation performance. Interface authentication and data verification requirements are strict to prevent sensitive data leaks or incorrect calls. This configuration scheme is compatible with FastGPT v4.17.0 interface functions.
How to set the configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| API Authentication Method | Bearer ${enterprise-specific API key} | This category’s production data involves core parameters such as insulation performance, so strict authentication is required to control access permissions |
| Request Variable Configuration | {"batchId": "required", "deviceSerial": "optional", "reportScope": "all"} | Adapt to business requirements for querying ledgers by batch or single device, clarify required parameters to reduce invalid calls |
| Response Data Filtering | Only return device identifiers, insulation parameters, test results, and document association fields. Single field length must not exceed 1000 characters | Reduce redundant data transmission, control the return volume of a single interface, and improve processing efficiency for production ledger summaries |
| Interface Timeout Duration | 300 seconds | Adapt to the time required to generate a single high-voltage test report, avoid normal requests from being forcibly interrupted |
| Retry Count | 2 times | Address common scenarios of network fluctuations on industrial sites, reduce the probability of single request failure |
| Large File Transfer Method | Return file download URL | Adapt to transmission requirements for large-volume documents such as insulating oil reports and test records, reduce interface load |
Three common configuration mistakes
- Phenomenon: The interface returns a 401 Unauthorized status code. The cause is that the
Authorizationparameter is not configured with a valid authentication key, or the key is not bound to the corresponding data access permission. - Phenomenon: The
responseDatafield returned by the interface is missing partial discharge test values. The cause is that the test report type was not specified invariablesduring the request, so the system did not pull the corresponding structured data. - Phenomenon: Timeout occurs when pulling ledgers for multiple devices in batches. The cause is that the timeout configuration was not adjusted based on the volume of a single report for this category, and the default short timeout duration was used.
How to confirm the configuration is correct
- Call the interface and pass a valid test device batch ID, check if the returned
responseDataincludes preset insulation parameters and test result fields. - Verify that the
Authorizationparameter is configured correctly, and call the interface without 401-level authentication errors. - Pass different
variablesparameter combinations, confirm that the interface can return production ledger data for the corresponding scope. - Simulate short-term network fluctuations, retry the interface call, confirm that the configured retry mechanism functions properly.
