What Data for This Category Looks Like
Core data for precast concrete components comes from BIM detailed design, rebar and concrete batch ledgers, mold table and curing kiln operation logs, laboratory test records, and QR code traceability systems. Documents involved in daily audits include component detailed drawings, rebar cutting lists, mold inspection reports, pouring and vibration records, curing cycle records, and demolding and factory inspection reports. Data update frequency follows per single component, per batch, or per kiln, covering the full process from component breakdown to factory delivery. This category produces large single-piece engineering components that correspond one-to-one with on-site lifting positions. Data must accurately match the identifying information of individual components, which differs from ready-mixed concrete categories that deliver fluid materials by truck.
What Constraints Do These Characteristics Impose on HTTP Interfaces and External Systems
Since data sources cover multiple internal systems, HTTP interfaces must support cross-system parameter transfer, including core identifiers such as component ID, batch number, and supplier code. The high-frequency, small-batch update requirement requires interfaces to adapt to batch scenarios of 10-20 records per single query, avoiding too large or too small data volume per request. The complex document structure requires the interface request body to include multi-dimensional verification fields, such as embedded position deviation and demolding strength. Additionally, the one-to-one correspondence between individual components and on-site lifting positions requires interface return data to accurately associate with a single component, and must not return redundant batch data, as this will increase audit matching costs.
How to Configure
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {access_token}, validity period determined through actual testing | Matches the authentication rules of internal systems in precast concrete component factories, preventing unauthorized access to inspection data |
variables | Key-value pairs containing component ID, batch number, and supplier code | Corresponds to core query dimensions for daily audits, and adapts to identifying fields in component detailed drawings and rebar cutting lists |
responseData | Only return demolding strength, embedded position deviation, and factory inspection qualification status | Filters redundant data, focusing on core verification items for supplier and in-process quality audits |
| Timeout Period | 30–60 seconds | Adapts to query delays for curing records and mold table data, avoiding timeouts during high-frequency calls |
| Request Body Format | JSON | Matches standard data interaction formats of BIM systems and laboratory systems |
| Pagination Parameters | Return 10–20 records per request | Adapts to batch audit requirements for components per kiln or per batch |
Three Common Mistakes
- Issue: After deploying a custom HTTP tool, the platform tool parameter panel is blank, and variables cannot be configured. Cause: The optional parameter structure of
variableswas not correctly declared in the tool configuration, causing the front end to fail to render parameter input fields. - Issue: When using a peanut shell address as the request address, the interface returns a
getaddrinfo EN-class error. Cause: Correct domain name resolution rules were not configured, or the request address did not include a port number, causing the system to fail to resolve the target server address. - Issue: A 401 unauthorized status code is returned after calling the interface. Cause: The
Authorizationparameter was not correctly carried in the request header, or the authentication token has expired.
How to Confirm Successful Configuration
- Call the test interface, pass in the batch number of a precast concrete component, and check if the returned data includes core audit fields such as demolding strength and embedded position deviation.
- View the interface log to confirm that the
Authorizationauthentication header was correctly carried, and the returned status code is 200. - Simulate batch calls (15 records per single call) and check that no timeout errors occur in the interface.
- Compare the returned data with the curing records exported from the laboratory to confirm that the fields match exactly.
