What the data for this category looks like
Environmental monitoring research report data primarily comes from publicly released monitoring station data from ecological environment authorities, sensor collection logs independently deployed by enterprises, and regional environmental quality analysis reports published by the industry. Data updates mostly follow hourly and daily cycles. Some special research reports update on a weekly basis. A single document typically includes fields such as monitoring site code, monitoring time period, pollutant concentration value, corresponding unit (such as μg/m³, mg/m³), exceedance judgment criteria, and regional environmental analysis conclusions. Some documents include structured annotations of original monitoring curves.
Constraints imposed on HTTP interfaces and external systems
The hourly, high-frequency update cycle requires HTTP interfaces to support high-concurrency calls. This prevents data timeliness issues caused by call delays. Multi-dimensional retrieval fields (monitoring sites, pollutant types, time range) require interfaces to support multi-parameter combination verification. This ensures accurate matching of target data. Value fields with units and structured monitoring curves require interfaces to retain field unit information during transmission. It also requires configuring reasonable request timeout thresholds to avoid interruptions during large-field transfers. Differences in data access permissions across monitoring regions require external systems to include identity verification parameters when calling interfaces. This ensures data calls meet compliance requirements.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 200 MB | Environmental monitoring research reports often include structured monitoring curve attachments. The maximum size of a single document typically does not exceed 200 MB, which prevents upload failures |
maxContext | 8000–12000 characters | The core content length of a single environmental monitoring research report usually falls within this range. Values beyond this range will be truncated, which reduces retrieval accuracy |
RECALL_TOP_K | Top 10 entries | Environmental monitoring research reports have a large number of similar data entries. Too many recalled entries increases interface response delay. Too few entries fails to cover target data |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Documents with large monitoring curve attachments take longer to parse. 600 seconds covers most parsing scenarios |
AUTH_TOKEN_EXPIRE | 3600 seconds | External systems have high call frequencies. A 1-hour token expiration time balances security and call convenience |
REQUEST_RATE_LIMIT | 100 requests per minute | Meets the high-frequency update requirement for environmental monitoring data. This threshold prevents interface overload caused by frequent calls |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- A
413 Request Entity Too Largeerror occurs when calling the interface. The cause is failure to adjust theUPLOAD_FILE_MAX_SIZEconfiguration. The default upload limit is smaller than the size of attachments included in environmental monitoring research reports. - A
maxLengthexception occurs when batch importing environmental monitoring research reports. The cause is failure to adjust themaxContextconfiguration. The default context length cannot accommodate the full content of a single research report. - Unit information is missing from monitoring data fields returned by the interface. The cause is failure to enable the unit retention configuration in interface parameters. This causes key unit fields to be lost from parsed structured data.
How to Verify Correct Configuration
- Call the upload interface for the largest single-size environmental monitoring research report. Confirm that the returned status code is
200 OK. Adjust theUPLOAD_FILE_MAX_SIZEconfiguration based on actual document size. - Send a multi-parameter combination retrieval request. Verify that the interface returns results matching the monitoring site, time period, and pollutant type. Confirm that the multi-parameter verification logic works correctly.
- Call the interface to obtain a document containing monitoring curves. Check whether the returned data includes unit fields. Confirm that the unit retention configuration is functioning properly.
- Send 100 consecutive interface call requests. Confirm that no overload errors occur. Adjust the
REQUEST_RATE_LIMITconfiguration based on actual call frequency.
