Data Characteristics for This Category
Monitoring device quality documentation includes design and development documents, risk management reports, test validation reports, production process specifications, manuals, maintenance handbooks, regulatory compliance declarations, and post-market surveillance reports. These documents originate from various departments: R&D, Quality, Production, and Regulatory Affairs. Data updates are relatively stable, occurring primarily after product iterations, regulatory changes, or adverse event analysis. Document structure typically follows medical device industry standards, such as the YY/T 0316 series. Fields cover technical parameters, performance indicators, test methods, risk levels, and defect descriptions. Units include V, mV, mmHg, bpm, %SpO2, and ℃. Precision and consistency requirements are high, often involving specific medical terminology and abbreviations.
Constraints Imposed by These Characteristics on "Deployment and Upgrade"
The complexity and specialized nature of monitoring device quality documentation place specific demands on FastGPT during deployment and upgrade. First, diverse document sources and formats require robust file parsing capabilities in the deployment environment, especially accurate extraction from PDF and Word formats, to prevent information loss due to parsing errors. Second, update frequency is stable but batch-oriented. Upgrades must prioritize efficient incremental updates and historical version management to ensure smooth data transitions. The extensive use of specialized terminology and units in documents requires the model to have strong semantic understanding, avoiding ambiguity during vectorization and retrieval. Furthermore, regulatory compliance mandates data security and traceability. Deployment requires strict access control and data backup policies. Upgrades must ensure data migration integrity and continuous audit logs. High demands for precision and consistency necessitate fine-tuning of text segmentation strategies and similarity calculations to ensure accurate question-answering results.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Monitoring device test reports and design documents often contain numerous charts and embedded objects, leading to large file sizes. This ensures successful uploads. |
maxContext | 3000 Tokens | Professional documents have strong contextual relevance, requiring a longer context window to understand complex technical details. |
Chunk size | 800–1200 characters | Monitoring device document paragraphs are typically long, containing multiple technical points. Shorter segments would split information. |
Recall count | Top 8 entries | This ensures enough relevant technical document fragments are retrieved for complex queries, improving accuracy. |
Similarity threshold | 0.75 | The medical device field demands high information accuracy. Raising the threshold reduces retrieval of irrelevant results. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Processing large PDF reports or Word documents with complex tables can be time-consuming. This prevents timeouts. |
Three Common Pitfalls
- Database creation failure or index failure after deployment often results from insufficient permissions for the database service or storage volumes in the Docker Compose configuration.
- Web search functionality configured but unresponsive or returning empty results occurs when
LLM_WEB_SEARCH_MODELis misconfigured or network proxy settings are not applied. - Inability to retrieve some historical documents after an upgrade commonly happens when the parser version for old documents is incompatible with the new model, leading to vectorization failure.
How to Verify Correct Configuration
- Upload a PDF document containing complex charts and specific medical terminology. Check if its content is fully and accurately parsed and vectorized.
- Ask questions about specific technical parameters or fault codes within the document. Verify the system can retrieve relevant document fragments and provide precise answers, including field names and units.
- Check system logs for file parsing and vectorization task completion status. Confirm no timeout or parsing failure error codes are present.
- Simulate a system upgrade. Observe the migration status of historical document indexes during the upgrade. After the upgrade, perform retrieval tests on some older documents.
