What this type of data looks like
Environmental monitoring data mainly comes from three sources: national or local ecological environment monitoring stations, online monitoring devices at enterprise sewage outfalls, and portable handheld monitoring equipment. Online monitoring data has an update frequency of minutes to hours. Manually collected data is updated according to fixed monitoring cycles. Each individual data document includes fields such as unique monitoring point identifier, sampling or monitoring time, pollutant concentration value, associated instrument number, and quality control verification mark. Units include category-specific identifiers such as μg/m³, mg/L, ℃, and %.
What constraints do these characteristics impose on citation source and traceability
Multiple data sources require the traceability system to bind specific monitoring points, instrument numbers, and collection subjects to prevent mixing of monitoring data from different stations. Minute-level update frequency requires traceability information to be precise to second-level timestamps to match the precise time windows required for research. The rich field structure requires traceability to associate metadata such as pollutant type and concentration unit, to ensure full correspondence between referenced values and their source. For cross-regional and cross-device monitoring data, the traceability chain must cover the entire process of data transmission and preprocessing, to ensure the credibility of research citations.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
reference_source_field | ["monitor_point_id", "collect_time", "instrument_id"] | These fields are core identifiers for environmental monitoring data, enabling precise location of the source subject and collection time of individual data records |
chunk_max_length | 800–1200 characters | A single environmental monitoring document contains multiple associated fields. Segmentation must retain complete traceability identifiers to avoid splitting core information |
retrieve_top_k | Top 6 entries | Research scenarios require coverage of monitoring data samples from multiple points and time periods. This value balances recall scope and result redundancy |
reference_enable_timestamp | Enabled | Environmental monitoring data has strong timeliness. Precise timestamps prevent confusion between similar monitoring data collected across different time periods |
reference_unit_check | Enabled | Multiple concentration measurement units exist in environmental monitoring. Verification avoids issues where referenced values do not match their source units |
parse_file_timeout_seconds | 300 seconds | Batch environmental monitoring documents contain multiple sets of monitoring data. Sufficient parsing time must be reserved to ensure complete extraction of all traceability fields |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and testing against appropriate samples is recommended before finalizing settings.
Three common misconfigurations
- Phenomenon: Generated citation IDs do not match the monitoring point and time of actual monitoring data, with forged citation identifiers appearing. Cause: The core fields configured in
reference_source_fieldare not bound, and only the document file name is used as the traceability basis, making it impossible to associate specific monitoring points and times. - Phenomenon: The knowledge base recall results include reference marker text such as
[1]in the output content. Cause: The display switch for thereference_show_markconfiguration is not turned off, or the context of the reference marker is not retained during segmentation, causing the marker to be output directly. - Phenomenon: System logs cannot distinguish source data from different monitoring stations. Cause: The
monitor_point_idorinstrument_idfield is not configured inreference_source_field, and the traceability chain does not include station or device identifiers.
How to confirm correct configuration
- Upload a single environmental monitoring document, view the parsed metadata in the knowledge base, and confirm that the configured traceability fields have been correctly extracted and associated.
- Initiate a research-related query, check the citation list in the returned results, and confirm that each citation is associated with specific monitoring point and timestamp information.
- View the system logs, confirm that source data from different monitoring stations has been correctly marked without confusion.
- Adjust the
retrieve_top_kparameter, and verify that the number of recall results matches the expected configuration.
