Data Structure for This Category
Photovoltaic module encapsulation production data is sourced from cell grading records, glass adhesive film backplane batch ledgers, MES systems, string welding and lamination equipment logs, and EL/IV tester output files. One record is generated per module and per material batch. Records include layout diagram number, material batch number, lamination process parameters, EL crack coordinates, IV test power value, insulation voltage withstand result, and other fields. Daily supporting documents include lamination process records and packing lists. The fields of a single module record cover key node information across the entire production process.
Constraints Imposed on HTTP Interfaces and External Systems
The quality traceability scenario for photovoltaic module encapsulation requires integration with multiple scattered production systems. Single records have many fields and are linked to multi-dimensional information such as batches, equipment, and test results. Traceability queries for each module must match interfaces from multiple data sources. Interface calls must support dynamic binding of variables including batch numbers and component IDs. Data update frequency is high, and defect analysis requires rapid response. Interfaces must have low latency, and support batch queries to adapt to traceability scenarios for batch modules. Transmission of unstructured data such as EL images and IV test reports requires interfaces to support binary or file stream format response processing.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Request timeout | 300 seconds | Adapts to standard query times for photovoltaic module data, prevents long tasks from blocking the system |
| Batch request limit | First 200 entries | Balances traceability efficiency of single-batch modules and interface load, aligns with industrial production batch processing habits |
Authorization | Bearer {custom access key} | Meets identity verification requirements for industrial systems such as MES and testers, ensures secure data interaction |
variables | Bind component ID and material batch number fields | Enables dynamic matching of interface parameters and production data, simplifies multi-system integration logic |
responseData | Return only power value, crack coordinates, batch number | Filters redundant data, reduces interface transmission overhead, meets core field needs of traceability systems |
Three Common Misconfigurations
- A 401 Unauthorized error is returned when calling external EL tester interfaces. The cause is that the
Authorizationparameter is not configured in Bearer token format, and no valid system access key is carried. - The
responseDatafield returned by the interface is empty. The cause is that the component ID parameter invariablesis not correctly bound, so the query condition cannot match the corresponding production record. - A timeout error is triggered by batch traceability requests. The cause is that the request timeout is set too short, which does not adapt to the combined query time of multi-batch module data.
How to Verify Proper Configuration
On the interface debugging page of FastGPT v4.17.0, call the configured interface, check that responseData returns preset core fields such as power value and crack coordinates. Replace the Authorization parameter with an invalid key, send a call request to confirm the interface returns a 401 status code, verifying that the identity verification logic works. Bind the test component batch variables parameter, call the interface to confirm that production record data for the corresponding batch is returned. Send a batch module traceability request, confirm that the interface returns complete results within the 300-second timeout period.
The values listed are common starting points and should be assessed against the samples relevant to the specific deployment.
