What the data for this category looks like
Data for this category comes from engineering orders, sand, gravel, cement and admixture inspection records, moisture content test reports, mixing plant control systems, and project laboratory records. Daily documents include mix proportion notices, opening identification forms, production and transport slips, raw material inspection documents, test block records, and strength reports. Data is updated at the frequency of per-vehicle production records, per-batch raw material test results, and daily laboratory ledgers. Fields include raw material moisture content, mix proportion parameters, slump index, and test block strength values. Units include kilograms, cubic meters, millimeters, megapascals, and others.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
High-frequency data updates at single-vehicle intervals require interfaces to support frequent calls, with single-response duration controlled within a reasonable range. Data from multiple sources must connect to multiple external interfaces such as mixing plant control systems and laboratory systems, so a unified authentication mechanism is needed to ensure data security. Both document-type slips and numeric test data coexist, so interfaces must support both form submission and structured data transmission. The delayed requirement for test block strength verification requires interfaces to support historical data backtracking queries, to associate full production process records.

How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer {External System API Key} | Standard token authentication is required when connecting to mixing plant control systems and laboratory systems, to secure interface calls |
| Maximum data returned per single request | First 20 entries | Production and raw material data per single vehicle interval are small in volume; 20 entries can cover complete information for the day's associated batches |
| Interface timeout period | 5000 milliseconds | External interfaces for ready-mixed concrete production typically respond within 3 seconds; a buffer is reserved to avoid normal requests being misjudged as timed out |
responseData parsing rules | Match slump, moisture content, and strength values via field mapping | Accurately extract core quality indicators for subsequent defect analysis and traceability logic |
variables injection parameters | Engineering order number, raw material batch number | Associate full production, transport, and inspection data to enable full-link traceability of quality problems |
| Number of failure retries | 2 times | Address occasional network fluctuations during high-frequency calls, reducing the probability of single request failure |
Three Common Misconfigurations
- Phenomenon: The number of associated data returned by the interface does not match the number of context entries displayed on the platform interface. The actual return is 310 entries, but only 30 entries are displayed on the interface. Cause: The correct maximum data returned per single request is not configured, or the platform's context loading pagination rules are not adapted.
- Phenomenon: Credential error is returned when calling an external system interface, and the call cannot be completed even after confirming that the key is correct. Cause: The token is not spliced according to the standard format required by
Authorization, or the authentication permission for the corresponding external system is not configured for the interface. - Phenomenon: Process execution that includes HTTP requests and problem classification times out, or the problem classification branch does not trigger the HTTP request. Cause: The HTTP request module is not configured as a mandatory execution link across branches, or a reasonable timeout threshold is not set based on the external interface's response duration.
How to Confirm the Configuration is Correct
- Call the test interface, check if the returned data fields include core quality indicators such as slump, moisture content, and strength values, to confirm that the
responseDataparsing rules are effective. - Simulate frequent calls to the interface, check for frequent timeouts or credential errors, to confirm that the
Authorizationauthentication and timeout period configurations are reasonable. - Trigger a full-process test, check if engineering orders, raw material batch numbers, and test block strength data can be associated, to confirm that the
variablesinjection parameter logic is correct. - Simulate abnormal scenarios, such as entering an incorrect raw material batch number, check if the interface returns the corresponding error information, to confirm that the failure retry mechanism is effective.
