What the Data for This Category Looks Like
Data for this category primarily originates from special equipment safety supervision systems, inspection and testing institution systems, user ledgers, and operator certificate databases. Daily documents include equipment use registration certificates, periodic inspection reports, maintenance records, hidden danger rectification notices, accident reports, and operator certificates. Covered fields include unique device identifiers, inspection cycles, maintenance cycles, operator qualification levels, and hidden danger rectification status. The data update frequency is monthly. Full latest status information tied to the entire device lifecycle must be synchronized.
Constraints on the Knowledge Base Retrieval and Recall Link
Monthly updated bulk data requires retrieval and recall to support incremental synchronization and full verification. Expired data must not be recalled. Multiple types of structured documents need to adapt to retrieval weights for different fields. Unique device identifiers should be prioritized for matching, for example. Highly compliant documents such as operator certificates and inspection reports require recall results to include complete valid period fields. Expired qualification information must not be output. Long text documents related to device lifecycles require limiting the length of a single recalled content piece. The context window must not be exceeded.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity | 0.75–0.85 | Matches special equipment terminology and device identifiers, filters low-correlation non-supervision content |
limit | Top 8 entries | Covers retrieval needs for multiple devices and multiple types of documents involved in a single service inquiry, avoids missing key information |
searchMode | Semantic Retrieval | Adapts to mixed retrieval scenarios of structured fields such as device numbers and inspection cycles, plus professional terminology |
usingReRank | Enabled | Re-sorts initial recall results based on document compliance and timeliness, prioritizes displaying the latest inspection reports and valid certificates |
datasetSearchUsingExtensionQuery | Enabled | Automatically supplements implicit conditions such as device type and supervision area in service inquiries, narrows the retrieval scope |
collectionIds | Bind corresponding datasets by supervision jurisdiction | Ensures only special equipment-related documents within the current jurisdiction are recalled, avoids cross-region data confusion |
Three Common Misconfigurations
- Phenomenon: The "Result Reranking" switch in the interface appears grayed out and unavailable, even if problem optimization has been enabled in the knowledge base plugin. Cause: The configuration hierarchy of the knowledge base plugin and the answer plugin is confused in the workflow configuration, causing the switch status to not take effect synchronously.
- Phenomenon: A prompt "Insufficient Quota for References" pops up when calling the knowledge base, and the number of returned results is less than the preset value. Cause: Special equipment datasets are not split by supervision jurisdiction, causing single dataset resource usage to exceed platform thresholds.
- Phenomenon: Recalled results include expired inspection reports or invalid operator certificates. Cause: Monthly incremental sync rules are not configured, causing retrieval data to not update the latest rectification and inspection status.
How to Verify Proper Configuration
- Manually input a service inquiry that includes a specific device number. Check whether the latest inspection report for the corresponding device appears in the recalled results.
- Navigate to the knowledge base configuration page. Confirm that the
usingReRankswitch can be toggled normally and the configuration saved. - Trigger the monthly incremental sync task. Check the system logs to confirm only special equipment documents added or modified in the current month are updated.
- View the retrieval logs. Confirm that the
similarityscore of the recalled results falls within the preset 0.75–0.85 range.
