What this category's data looks like
Data for this category primarily comes from raw fiber inspection, ERP systems, real-time data from spinning and weaving machines, evenness testers, fabric inspection machines, and order specifications. Daily documents include cotton blending or batching lists, process setup sheets, equipment operation records, yarn inspection certificates, grey fabric inspection certificates, and defect ledgers.
Data updates synchronize with each batch of raw materials, each shift’s operations, and each piece of fabric produced. Fields include fiber breaking strength, evenness CV value, spinning twist, weaving structure parameters, fabric defect type and location, and more. Units include cN/dtex, twists per meter, meters, and others.
What constraints do these characteristics impose on HTTP interfaces and external systems
The high-frequency update nature of this category’s data requires HTTP interfaces to support multiple requests per second. This avoids blocking equipment inspection processes due to request delays.
Multiple heterogeneous data sources require interfaces to adapt to field formats returned by different systems. For example, raw data from evenness testers differs in field structure from batching lists exported from ERP.
Single-batch data volume is generated with each piece of fabric produced. Interfaces must support bidirectional transmission of single records and batch records. They must also support text fields from defect ledgers and numeric fields from equipment parameters, to prevent data parsing errors.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Request timeout period | 60–120 seconds | Matches the real-time response rhythm of equipment inspections, to avoid blocking production line operations |
| Authorization configuration | Fill in the exclusive token generated by the connected system | Ensures identity legitimacy of interface calls, prevents unauthorized access |
variables field binding | Map fields one by one according to cotton blending lists and defect ledgers | Accurately transmit core business parameters and inspection records |
responseData parsing rules | Configure field matching according to data source formats | Compatible with return data from different sources such as ERP and spinning machinery equipment |
| Batch request limit | First 10 records per request | Matches the business data volume generated per piece of fabric, avoids interface overload |
| Retry trigger threshold | Trigger after 2 consecutive failures | Respond to temporary request failures caused by network fluctuations |
Three common configuration errors
- Interface calls return timeout errors, with status code 504 or a request timeout prompt. The cause is that this category has a high data update frequency, with many business fields carried in a single request. The default timeout period is insufficient to complete data transmission and parsing.
- Calling external system interfaces returns empty fields or no results. The cause is that business fields are not bound according to the
variablesrules. Passed parameters do not match the requirements of the external system. - After uploading equipment inspection record files, the index completion status cannot be confirmed. The cause is that the
responseDataparsing rule is not configured to extract the returned task ID. It is impossible to verify processing progress via polling the interface.
How to confirm the configuration is properly set
- Initiate a single test request, pass simulated data from a cotton blending list. Check whether the external system can correctly receive the field content bound by
variables. - View the return result after calling the interface. Confirm that the fields parsed by
responseDatamatch the fields in local business documents. - Simulate high-frequency requests. Verify that the interface does not experience timeouts or errors during continuous calls. Adjust the timeout period to match the business rhythm.
- Trigger the retry mechanism. Confirm that the interface can automatically resume normal calls after temporary network fluctuations.
