Biopharmaceutical Equipment Pharmacovigilance Deployment and

Data Characteristics for This Category

Data in the pharmacovigilance domain for biopharmaceutical equipment primarily originates from technical documentation, maintenance manuals, calibration records, firmware update logs, and user operation logs provided by equipment manufacturers. This data typically exists in PDF, XML, JSON, or proprietary binary formats. Update frequency is irregular, usually occurring with firmware upgrades, software version iterations, or known defect releases. Document structures are complex, containing extensive specialized terminology, diagrams, and flowcharts. Fields include equipment model, serial number, firmware version, sensor readings, alarm codes, operating parameters, batch information, and fault descriptions. Units are diverse, such as temperature (°C), pressure (kPa), flow rate (mL/min), and time (seconds, hours), with different equipment potentially using different unit standards.

Constraints Imposed by These Characteristics on "Deployment and Upgrade"

The complexity and diversity of equipment manufacturer documentation demand more robust document parsing capabilities during deployment. This requires configuring longer timeouts to handle large or structurally complex PDF files. Irregular data updates mean the knowledge base synchronization strategy must support a combination of manual and API triggers, avoiding frequent full synchronizations. The presence of specialized terminology and diagrams challenges text embedding model selection and chunking strategies, necessitating more refined text preprocessing and longer chunk lengths to preserve context. Diverse fields and units require the RAG retrieval process to effectively identify and match different forms of expression, preventing misjudgments due to unit inconsistencies. This may also require customized post-processing logic to standardize numerical representations. For private deployments, Docker container resource allocation must be adjusted based on document size and processing complexity.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`1000 MB`	Accommodates equipment documentation containing numerous diagrams and detailed logs, ensuring large files can be uploaded.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Processes complex PDF or XML documents, preventing task failure due to excessively long parsing times.
`Chunk size` (Chunk Length)	`800–1200 characters`	Preserves the integrity of context in biopharmaceutical equipment technical documentation, preventing critical information from being truncated.
`Recall count` (Recall Count)	`Top 5 entries` (Top 5)	Ensures retrieval covers multiple knowledge points related to equipment faults and operating procedures.
`Similarity threshold` (Similarity Threshold)	`0.75`	Balances retrieval precision and recall, reducing irrelevant results while not missing potential information.
`Rerank result count` (Reranked Return Count)	`Top 3 entries` (Top 3)	Further optimizes results based on initial recall, focusing on the most relevant equipment fault diagnosis or maintenance steps.

Three Common Pitfalls

An application access address displaying a "spinning circle followed by failure" typically indicates misconfigured Docker container port mapping or firewall rules, preventing external access to internal service ports.
Login failure after modifying the root user password might occur if only the database password was changed without simultaneously updating the database connection credentials in the FastGPT application configuration, leading to the application being unable to connect to the database.
When the knowledge base processes equipment log files, some critical parameters (e.g., pressure values, temperature ranges) may be missing or incomplete in the retrieval results. This happens when the file parsing fails to correctly identify or extract numerical fields with units.

Verification Steps

Upload a PDF equipment manual containing complex diagrams and lengthy technical descriptions. Observe if the file parses correctly and if knowledge base construction completes, then check if chunked content is complete.
Modify FastGPT application configurations, such as OPENAI_API_KEY, via API or UI. Restart the service and verify that changes take effect and the application can correctly call external models.
Simulate a typical equipment fault scenario. Ask questions about fault diagnosis and troubleshooting steps. Check if the returned results accurately include the corresponding equipment model, alarm codes, and operating procedures from the manual, and verify unit consistency for key parameters.
Review FastGPT operational logs. Confirm no timeout or out-of-memory errors occurred during file parsing and vectorization, paying particular attention to resource usage when processing large equipment documents.
