What this category of data looks like
Data sources for process-related data in lithium-ion cell manufacturing include raw material batch records, workshop MES systems, slurry and coating testing equipment, dew point monitoring devices, formation and grading cabinets, and laboratory testing equipment. Data update cycles cover real-time synchronization for each battery batch and individual cell. Daily business documents include batching records, coating and rolling parameter logs, winding or stacking operation records, liquid injection parameter logs, formation and grading data reports, and OCV and safety test reports. Core data fields include raw material batch numbers, roll gap values, linear speed, charge-discharge current, dew point temperature, capacity values, and other key parameters.
Constraints Imposed on HTTP Interfaces and External Systems
Multi-source real-time production data requires interfaces to adapt to high-frequency, small-batch request rhythms. Interfaces must prevent external system overload from excessive request rates. Diverse business document structures require interfaces to support input and validation of multiple parameter types. Interfaces must ensure correct invocation of process data across different scenarios. High requirements for data accuracy from electrochemical systems require interfaces to strictly validate the legibility of input and output fields. Interfaces must prevent abnormal data from entering production links. Independent data attributes for each battery batch require interfaces to bind global variables corresponding to the batch. Interfaces must avoid cross-batch data confusion that disrupts production consistency.
How to Set Configurations
All configurations below are adapted for FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {Enterprise-specific API key} | Complies with identity verification specifications for external systems, prevents unauthorized access to sensitive process data |
variables | Bind three types of global variables: battery batch number, coating parameters, and formation and grading data | Matches core business data dimensions of lithium-ion cell manufacturing, ensures real-time production data can be associated during Q&A invocations |
responseData | Only return three types of fields: process parameter verification results, standard matching degrees, and anomaly alerts | Filters redundant data, adapts to rapid decision-making needs in production scenarios, avoids disrupting production workflows |
| Request timeout threshold | 10–30 seconds | Adapts to the real-time synchronization rhythm of formation and grading data, prevents production flow blockage from interface delays |
| Global variable assignment rule | Trigger automatic assignment by production batch | Matches the update frequency of process data for each battery batch, ensures the data source for Q&A invocations aligns with the current production batch |
| Request frequency limit | No more than 50 requests per batch | Adapts to the update rhythm of production data, avoids exceeding interface call quotas for external systems |
Three Common Configuration Mistakes
- The interface returns a 401 status code with empty response fields. Incorrect configuration of the
Authorizationparameter or missing valid enterprise-specific API key causes identity verification failure. - Global variables are not automatically updated by production batch. Q&A invocations return process parameters from an older batch. This occurs when the rule for triggering variable assignment by production batch is not set. The variable binding logic does not match actual production rhythms.
- Interface response delays cause slow text output, failing to meet real-time process Q&A requirements. This stems from improperly set request timeout thresholds and lack of pre-validation for response data. Invalid data occupies interface bandwidth.
How to Confirm Configurations Are Correct
- Send a test request with a valid
Authorizationparameter. Confirm the returned status code is 200 and the response fields are not empty. - Trigger a variable update for one production batch. Check if the global variables bound to
variablesare synchronized to the process data of the current batch. - Simulate multiple high-frequency requests. Confirm the interface response time meets the preset 10–30 second timeout threshold requirement.
- Call the process Q&A interface. Confirm the returned parameters match the document records of the current production batch.
