What data for this category includes
Precast concrete components include PC components, pipe piles, bridge components, and similar items. Data sources cover BIM detailed design documents, steel bar and concrete batch ledgers, mold table and curing kiln operation records, laboratory test reports, and QR code traceability systems. Data is updated per individual component, per batch, and per kiln. Daily documents include component detailed drawings, steel bar cutting lists, mold inspection records, pouring and vibration records, curing records, and demolding factory inspection reports. Data fields include component ID, external dimensions, steel bar usage, concrete grade, curing period, demolding strength requirements, and more. Units include millimeters, cubic meters, megapascals, and more.
Constraints on HTTP interfaces and external systems
The business requirement to match precast concrete components one-to-one with on-site lifting positions requires interfaces to support accurate data retrieval using individual component IDs. The multi-source data update pattern (per component, per batch, per kiln) requires interfaces to be compatible with field formats from different systems, and support real-time retrieval of the latest test and production data. The high severity of errors requires interfaces to validate the integrity of returned fields, to avoid missing critical parameters that lead to quotation errors. The wide variation in data volume for single large components requires interfaces to support limiting the number of components per request, to prevent data transmission overload.
Configuration Settings
This configuration applies to FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {precast component factory internal API key} | Used for identity verification when connecting to internal systems such as factory BIM and laboratories, to ensure data access security |
variables | {"target_component_ids": ["PC-202405-001", "PC-202405-002"], "required_fields": ["steel bar usage", "concrete grade", "curing strength"]} | Limits retrieval to precast component IDs and core quotation fields corresponding to the bidding project, to accurately match business requirements |
responseData | Return structured single or batch component data | Facilitates direct import into tendering document and quotation preparation tools, reducing format conversion costs |
| Maximum number of components per single request | First 30 entries | Avoids excessive data retrieval per request, adapting to bandwidth limits of internal factory interfaces |
| Request timeout period | 600 seconds | Addresses time requirements for data retrieval of large bridge components, pipe piles and similar items, calibrated based on actual measurements |
Three Common Configuration Mistakes
- An interface returns a 500 status code with a prompt that no valid link is configured. Cause: The
Authorizationparameter is not set correctly, or the data source address of the internal factory system is not bound invariables. - The
responseDatafield returned by the interface is missing critical parameters such as steel bar usage or concrete strength. Cause: Core fields to be retrieved are not explicitly specified invariables, resulting in returned data that cannot support quotation preparation. - The interface returns a general request failure prompt, suggesting checking network connection. Cause: The number of components per single request is not limited in
variables, resulting in single request data volume exceeding the carrying limit of internal factory interfaces.
How to Verify Correct Configuration
- Call the interface with a specified precast component ID, check if the returned
responseDataincludes core fields required for tender quotation such as steel bar usage and concrete grade. - Verify that the
Authorizationparameter carries a valid factory internal API key, confirming that the identity verification process works properly. - Submit the
variablesparameter containing batch component IDs, confirm that the returned data volume matches the preset maximum number of requests per single request. - Simulate data retrieval for large precast components, confirm that no timeout error is triggered and data is returned completely.
