What This Category of Data Looks Like
Data for petroleum refining quality traceability and defect analysis comes from DCS/APC control systems, LIMS laboratory management systems, tank farm metering systems, crude oil evaluation databases, equipment management systems, and energy systems. Daily documents include operating procedures, production plans, material balance reports, distillate outlet quality reports, interlock logs, shift handover records, and change management documents. Data update cycles cover real-time, shift-based, and daily frequencies. Fields include distillation range, flash point, sulfur content, and others, with corresponding units such as ℃, mg/kg, and others.
What Constraints These Characteristics Impose on the "HTTP Interfaces and External Systems" Link
Multiple data source systems require HTTP interfaces to support cross-system requests across multiple endpoints and adapt to authentication rules for different systems. Real-time, shift-based, and daily update cycles require interfaces to distinguish synchronization frequencies; real-time data interfaces must set reasonable polling intervals or maintain long connections. Diverse document and field types require interfaces to support transmission of both structured and unstructured data, with fields matching dedicated parameters for petroleum refining business. Associated data requirements for coupled units require interfaces to support carrying association identifiers to enable linked traceability of cross-unit data.
How to Configure the Settings
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {Enterprise Industrial System Exclusive Token} | Connecting to internal systems such as DCS and LIMS requires unified identity authentication, which meets the security access requirements of industrial scenarios |
variables | Pass in refining business variables such as {"crude_type": "", "shift_time": ""} | Adapt to quality data filtering requirements for different crude oil types and shifts |
responseData | Only return the fields flash_point, distillation_range, sulfur_content | Reduce invalid data transmission and improve interface response efficiency |
| Timeout Setting | 600 seconds | Meet the time-consuming requirements of processing batch data requests such as crude oil evaluation and material balance |
| Retry Strategy | Retry 3 times after failure, with a 30-second interval | Address temporary connection abnormalities caused by industrial network fluctuations |
| Data Encoding Format | UTF-8 | Support multi-language business fields and unit identifiers |
Three Common Configuration Mistakes
- Phenomenon: Unable to specify dedicated parameters for document parsing when calling the interface, and the returned refining report parsing results do not meet business requirements. Cause: No parsing rule variables configured in
variables, and the parsing requirements for refining-specific documents not passed to the external system. - Phenomenon: Timeout error triggered when obtaining LIMS quality data via HTTP request. Cause: The timeout setting not adjusted according to the update cycle of real-time data, and the interface timeout set to an excessively short duration that cannot cover the batch data processing cycle.
- Phenomenon:
undefinederror returned when calling the interface, with no clear error message. Cause:Authorizationparameter not configured correctly, causing the external system to reject authentication and return undefined response content.
How to Confirm the Configuration Is Correct
- Initiate a test request, pass preset refining business variables, and check whether the fields returned in
responseDatamatch the preset quality traceability fields. - Simulate a batch data request, check whether the interface response duration meets business requirements, and adjust the timeout setting to cover normal request cycles.
- After configuring the
Authorizationparameter, initiate a request to confirm that the external system returns valid business data with no authentication-related errors. - Simulate a single request failure scenario, check whether the interface performs retry operations according to the configured retry strategy, and verify that the failure handling logic takes effect.
