What Data for This Category Looks Like
Data for this category comes from full production flows of coating, resin, additive, agrochemical intermediate, and specialty chemical enterprises. Daily documents include batch production orders, material feeding review slips, reaction process records, cleaning records, inspection reports, deviation and change orders. Data sources cover formula and process libraries, material batches, reactor DCS, weighing systems, LIMS, and warehouse systems. Update frequency follows per batch production and each key process step. Data fields include batch number, material feeding amount, reaction temperature, cleaning residue detection values, and more. Units include kilograms, degrees Celsius, ppm, and others. Single-batch data volume varies based on process step complexity.
Constraints Imposed by Category Characteristics on HTTP Interfaces and External Systems
This category uses multi-variant, batch-switching production. It requires HTTP interfaces to pull exact matching data by batch number, to avoid cross-batch data confusion. Data updates per batch and key process step. It requires interfaces to include batch parameters to trigger real-time data pulls, to ensure the latest data for the current production batch is obtained. Multi-source system data needs interfaces to connect to multiple external systems like reactor DCS and LIMS. It requires interface authentication to support unified management of multi-system tokens. Additionally, unstructured content from documents like cleaning records and deviation change orders requires interface return data to include field mapping rules, to facilitate subsequent AI Q&A extraction of key information.
Configuration Setup
This configuration is adapted for FastGPT v4.17.0. The details are listed below:
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Authorization | Bearer external system token | When connecting to multiple systems such as reactor DCS and LIMS, identity verification must be completed using this parameter. Tokens must be obtained from the operation and maintenance interfaces of the corresponding systems. |
| variables | Assign values based on production batch number | Data in this category updates per batch. This parameter binds current batch production orders and feeding data, ensuring Q&A context matches the current production task. |
| responseData | Extract fields batch number, material feeding review result, reactor temperature | Core business data for this category revolves around batches. Only extracting key fields reduces interface transmission overhead and improves Q&A response speed. |
| Interface timeout period | 30–60 seconds | Some data for this category must be aggregated from multiple systems. The timeout period must cover the full process of data pulling and aggregation. Adjust based on actual measurements. |
| Single return data volume | 1000–2000 characters | Core single-batch data volume for this category is moderate. This range ensures interface transmission efficiency and data integrity. |
Three Common Configuration Mistakes
- The
responseDatafield returned after interface calls is empty, and prompts show no matching data. The cause is that the current production batch number is not included in the request parameters. This prevents the interface from accurately pulling equipment inspection data for the corresponding batch. - Multiple concurrent batch production requests trigger global variable overwrites, leading to chaotic Q&A results. The cause is that the variable scope is not set to single-request isolation. Global variables are shared in memory, which does not fit the multi-batch parallel production scenario of this category.
- Interface calls trigger timeout errors after more than 60 seconds. The cause is that the timeout period is not adjusted to meet the multi-system data aggregation requirements of this category. The default timeout period is insufficient to complete cross-system data pulling.
How to Verify Correct Configuration
- Manually enter a specified production batch number, trigger an interface call, and check if the returned
responseDataincludes fields such as material feeding review results and reactor temperature for the corresponding batch. - Initiate two interface calls for different batches, and check if the batch number bound in
variablesmatches the input values of the two requests respectively. This confirms variable isolation. - Adjust the interface timeout period to 20 seconds, trigger a data aggregation request, and verify that a reasonable timeout prompt is triggered. This confirms the timeout configuration is active.
- Check if the
Authorizationparameter includes the correct external system token. Call the interface and confirm the returned status code is 200. This verifies that the authentication configuration is active.
