What this category of data looks like
Data for this category originates from material grade archives, customer technical requirements, temperature control instruments, furnace temperature uniformity testing equipment, hardness testers and metallographic testing equipment, and workshop MES systems. Daily documents include heat treatment process cards, furnace loading layout drawings, real-time furnace temperature curves, hardness and metallographic test reports, equipment inspection sheets, and abnormal disposal documents. Data updates per furnace charge or batch. Each individual record includes fields such as heating temperature, holding duration, cooling parameters, furnace loading position, and test results. Units include degrees Celsius, hours, HV hardness values, and other relevant units.
Constraints for HTTP interfaces and external systems
This category of data updates per furnace charge or batch. Interfaces must support precise queries using furnace charge ID or batch number to avoid returning irrelevant data. Metadata for multiple document types must be transmitted via interfaces, and format validation for varying field types must be supported. Data sources include multiple external systems such as workshop instruments and MES systems, so interfaces must implement a unified authentication logic. The high-frequency update feature requires interfaces to have low-latency response capabilities. Interfaces must also support retry mechanisms for failed requests to prevent single request failures from disrupting inspection workflows. Q&A data for equipment inspection and maintenance must be linked to abnormal disposal documents, so interfaces must support cross-document associated queries.
How to set configurations
These configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {pre-configured API key} | Complies with standard authentication formats for industrial external interfaces, ensuring secure interface calls |
| Request timeout | 30–60 seconds | Transmission delays for heat treatment furnace temperature curves and inspection records are typically within a few seconds; this range reserves buffer time for network fluctuations |
| Concurrent request limit | 3–5 | Matches the concurrent carrying capacity of most workshop industrial equipment, avoiding 429 errors |
| Single return data size | No more than 1000 characters | Reduces invalid data transmission, speeds up Q&A response, and adapts to lightweight retrieval scenarios |
variables | Pre-set furnace charge ID and material grade as global call variables | Simplifies parameter passing for equipment inspection and maintenance Q&A, adapting to dedicated data query needs for individual furnace charges |
responseData | Only return inspection results, exception codes, and maintenance suggestion fields | Filters non-essential data and focuses on core information required for maintenance Q&A |
Three common mistakes
- 429 status code returned by the interface. Cause: No concurrent request limit configured, exceeding the concurrent limit of the external interface.
- Database workflows fail to retrieve data. Cause: Furnace charge ID is not used as the query condition, and the full data interface is called directly, or authentication parameters for the database connection are configured incorrectly.
- Interface returns empty fields. Cause: The furnace charge ID parameter in
variablesis not passed correctly, so inspection and maintenance data for the corresponding heat treatment furnace cannot be matched.
How to verify correct configuration
- Initiate an interface call for a single furnace charge data record, and check if the returned
responseDataincludes expected inspection and maintenance related fields. - Simulate multiple concurrent requests, observe if 429 exceptions are triggered, and adjust the concurrent request limit to match the carrying capacity of the external interface.
- Connect to a test database, execute the preset SQL query statement, and confirm that test data for the corresponding heat treatment furnace can be returned normally.
- Check the format of the
Authorizationauthentication parameter, confirm it complies with the authentication requirements of the external interface to avoid authentication failures.
