What Data for This Category Looks Like
This category of data comes from customer drawings, special characteristic lists, ERP/MES systems, measuring and testing equipment, and supplier quality certificates. Daily documentation includes control plans, process flow diagrams, work instructions, first-piece and patrol inspection records, SPC reports, PPAP materials, and 8D reports. Data is updated per production batch, collected synchronously for each batch and shift, with some equipment parameters uploaded continuously. The document structure includes customer-specified special characteristic numbers, process parameters, batch identifiers, and inspection result values. Fields must align with the quality system requirements of vehicle customers. Units are mostly industrial standard units such as millimeters, newton meters, and seconds.
What Constraints These Characteristics Impose on the "HTTP Interfaces and External Systems" Link
Data for this category is scattered and has significantly different update rhythms. HTTP interfaces must support batch synchronization and real-time pulling of multiple data sources, while being compatible with field format differences across systems. Documentation must strictly align with the quality system requirements of vehicle customers. Interfaces must carry verification fields to confirm data compliance, preventing batch data from being rejected due to format incompatibility. The volume of documentation for high-volume manufacturing is large, so interfaces must support paged transmission to avoid single-request timeouts. Errors can lead to batch defects and customer claims, so interfaces must include failure retry and exception reporting mechanisms to ensure uninterrupted data synchronization.
How to Configure Settings
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {Enterprise-specific API key} | Ensures identity verification for interface calls, complying with security access requirements for industrial systems |
| Knowledge base chunk size | 800–1200 characters | Adapts to the field length of automotive component documentation, improving indexing efficiency |
| Maximum data per single request | 1000–2000 entries | Matches the volume of documentation per batch for high-volume manufacturing, avoiding request timeouts |
| Maximum search results per query | Top 5 entries | Adapts to the cross-review needs of automotive component documentation, avoiding interference from excessive irrelevant data |
variables | Bind business variables such as batch number, special characteristic ID | Enables precise association between documentation and corresponding production batches, meeting customer quality traceability requirements |
responseData | Return only documentation entries that pass compliance verification | Filters invalid data, reducing processing load for downstream systems |
Three Common Misconfigurations
- Issue: A 401 Unauthorized error is returned when calling the knowledge base or chat interface, or the specified knowledge base collection cannot be associated. Cause: The
Authorizationparameter is not configured correctly, or the key is not bound to the exclusive knowledge base permissions of the corresponding customer. - Issue: The indexing speed after QA splitting is too slow for file collections created via the knowledge base interface. Cause: Exclusive knowledge base collections are not divided by customer code, leading to an overly large indexing coverage range, and the associated scope is not narrowed in a targeted way.
- Issue: Key business fields are missing from the
responseDatareturned by the interface, or batch requests time out. Cause: Required fields such as batch number and special characteristic ID are not bound invariables, or the data volume per single request exceeds the reasonable limit, and paged transmission is not configured.
How to Confirm the Configuration Is Complete
- Call the
Authorizationverification interface, confirm that the returned status code is 200, and there are no permission-related errors. - Upload a single batch of test documentation, pull data via the interface, and verify that the returned
responseDataincludes the bound business variable fields. - Check the association scope of the knowledge base collection, confirm that it has been divided by customer code to narrow the indexing coverage range.
- Simulate batch requests, observe the interface response duration, and adjust the data volume per single request to the reasonable interval.
