What Data for This Category Looks Like
Daily data sources for precast concrete components include BIM detailed design documents, reinforcement bar and concrete batch management ledgers, mold table and curing kiln operation logs, laboratory test reports, and product QR code traceability systems. Data is synchronized for update per individual component, per production batch, and per curing kiln cycle. Core documents include component detailed drawings, reinforcement bar cutting lists, mold inspection records, pouring and vibration records, curing records, and demolding and factory inspection reports. Data fields include component ID, reinforcement bar diameter (mm), curing temperature (℃), strength grade (MPa), and other fields, and are bound one-to-one with on-site lifting positions.
What Constraints These Characteristics Impose on HTTP Interfaces and External Systems
Since data is updated per individual component, production batch, and curing kiln cycle, interfaces must support precise data retrieval by component ID, batch number, and kiln number to avoid unnecessary redundant requests. Cross-review of multiple document types requires interfaces to support integration with multiple data source systems, and adapt to identity verification rules of different systems. The one-to-one binding between data and on-site lifting positions requires that fields returned by the interface must be accurately matched, with no mismatches. For business attributes with serious error consequences, the interface must have a complete return verification mechanism to ensure core verification fields are not missing.
How to Set Configurations
The following configurations are based on FastGPT v4.17.0, adapted for the technical document cross-review scenario for precast concrete components.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Timeout Configuration | 600 seconds | When integrating with industrial equipment such as mold tables and curing kilns, as well as laboratory interfaces, the data return cycle covers normal production rhythms, preventing premature request interruptions |
Authorization | Bearer {Factory Internal API Key} | Complete identity verification when connecting to multiple data source systems, ensuring data transmission security |
variables | Bind component ID and curing kiln ID | Retrieve data per individual component or batch dimension, matching update frequency requirements per piece or batch |
responseData | Only return component ID, reinforcement bar diameter, and curing strength value | Filter non-core fields, focusing on core verification content for technical document cross-review |
| Multi-document parameter format | Pass document identifiers in array form | Support cross-verification requirements for multiple documents such as reinforcement bar cutting lists and curing records |
| Single request limit | Top 20 entries | Match the number of components produced per kiln, avoiding excessive occupation of interface resources |
Three Common Errors
- Phenomenon: The interface request times out automatically after 1 minute, returning a 504 gateway timeout status code. Cause: The timeout configuration was not adjusted, and the default short timeout setting was used, which cannot adapt to the data return cycle of industrial equipment and laboratories.
- Phenomenon: The interface returns empty fields after being called, and reinforcement bar cutting list related data cannot be obtained. Cause: The
variablesparameter was not bound correctly, and the correct component ID variable was not passed, resulting in failure to match corresponding production data. - Phenomenon: Only the verification result of a single document is returned during multi-document requests. Cause: Multiple document identifiers were not passed in the correct format, and the interface only recognizes the first request content, unable to complete multi-document cross-review.
How to Confirm the Configuration Is Complete
- Initiate a test request using a single component ID, check that the returned fields include the preset core verification content.
- Simulate a timeout scenario, verify that the request completes and returns within 600 seconds, with no interrupt error triggered.
- Pass multiple document identifiers, confirm that the interface returns verification results for the corresponding multiple documents.
- Check that the
Authorizationparameter format is correct, with no identity verification failure errors.
