Deployment and Upgrade for Surgical Robot Quality

Data Characteristics for This Category

Surgical robot quality documentation data originates from the entire product lifecycle: design, development, production, testing, clinical application, and maintenance. Data updates frequently, covering version iterations, software upgrades, hardware maintenance, and consumable replacements. Document structures are complex, including technical specifications, risk assessment reports, verification and validation records, user manuals, maintenance manuals, and compliance declarations. Fields and units are highly specialized, for example, robotic arm degrees of freedom, positioning accuracy (micrometers), image resolution (pixels/mm), sensor sampling frequency (Hz), software version numbers, firmware version numbers, sterilization cycles, and calibration parameters. These documents typically exist in formats like PDF, Word, and Excel, and may contain numerous charts, CAD model links, and embedded videos.

Constraints Imposed by These Characteristics on "Deployment and Upgrade"

The complexity and specialized nature of surgical robot quality documentation impose specific requirements on FastGPT's deployment and upgrade processes. High update frequency means the knowledge base must support efficient incremental update mechanisms to avoid reprocessing large amounts of unchanged content. Multi-format documents and embedded content require FastGPT's parser to have robust heterogeneous data processing capabilities, accurately extracting text, identifying key fields, and associating non-textual information. Micrometer-level precision demands fine-grained semantic preservation during vectorization to prevent loss of critical technical parameters. The ability to identify fields like version numbers and batch numbers is crucial for tracing quality issues to specific products or batches. This requires structured information extraction during text preprocessing. Therefore, deployment needs to optimize data ingestion, chunking strategies, and vector model selection for these characteristics.

Configuration Guidelines

Configuration Item	Suggested Value	Rationale for This Value
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Surgical robot documents are typically long and complex, requiring more parsing time.
`maxContext`	`800–1200 characters`	Ensures sufficient context, including key technical details and operating procedures.
`Chunk size` (Chunk Size)	`300–500 characters`	Balances semantic completeness with recall efficiency, preventing long paragraphs from diluting key information.
`Recall count` (Retrieval Count)	`Top 8`	Increases the coverage of relevant document snippets, improving the probability of retrieving critical information.
`Similarity threshold` (Similarity Threshold)	`0.75–0.85`	Ensures high relevance of retrieval results, filtering out irrelevant general descriptions.
`ENABLE_INCREMENTAL_UPDATE`	`true`	Adapts to the high-frequency updates of quality documentation, reducing resource overhead for reprocessing.

Three Common Pitfalls

After a knowledge base update, risk assessment reports for a specific version number are not retrievable. This occurs when the document parser fails to correctly identify and extract the version number field from the document, leading to the loss of this key identifier during vectorization.
After upgrading the FastGPT version, parsing speed for some documents significantly decreases, and timeout errors occur. This may be because the new version's default PARSE_FILE_TIMEOUT_SECONDS parameter value is too low, failing to accommodate the complexity of surgical robot documents.
Retrieval results returned by the system contain numerous general descriptions not directly related to the query topic. This typically happens when the Similarity threshold (Similarity Threshold) is set too low, causing non-core content to also be deemed relevant.

How to Verify Correct Configuration

Upload a technical specification document containing multiple version numbers. Query using keywords and version numbers, then verify if the returned results accurately include information for the corresponding versions.
Monitor file parsing logs after an upgrade. Check if the number of PARSE_FILE_TIMEOUT_SECONDS-related timeout errors has significantly decreased.
Select a set of typical queries. Examine the distribution of Similarity scores in the retrieval results to ensure that most results have similarity scores above the set threshold.
Simulate an incremental update operation. Confirm that old documents in the knowledge base are not reprocessed and that content from new version documents has been successfully incorporated.
