HTTP Interface and External Systems for Surgical Robotics

Data Characteristics for This Category

Surgical robotics product data typically includes device status, sensor readings, surgical logs, consumable usage, and software version information. Data sources primarily consist of the robot's embedded controller, connected external imaging devices, operating room information systems (ORIS), and manual input from medical staff. Update frequencies vary significantly; sensor data can be millisecond-level, device status is usually second- or minute-level, while consumables and surgical logs often update after each operation or daily. Document structures generally adhere to medical device industry standards like DICOM, HL7, or manufacturer-specific proprietary protocols. Data field naming is standardized, often including timestamps, device serial numbers, operator IDs, and parameter units (e.g., millimeters, degrees, volts). Some data may be stored as binary streams or in proprietary formats, requiring specific parsing libraries.

Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"

The high-frequency updates and diverse sources of surgical robotics product data demand that HTTP interfaces possess high throughput and low-latency processing capabilities to prevent data accumulation or loss. The existence of specialized data formats, such as DICOM images or binary device logs, means HTTP requests may need to support various Content-Type headers and perform appropriate encoding conversions before data transmission. The strictness of fields and units, especially concerning measurement precision and safety-critical operational parameters, requires rigorous data type and value range validation during interface design to prevent safety hazards due to format errors. Additionally, much medical data is privacy-sensitive, imposing higher requirements for data transmission encryption and authentication. For example, HTTPS is mandatory, and integration with OAuth2 or JWT for authorization may be necessary, increasing interface configuration complexity.

Configuration Guidelines

Configuration Item	Recommended Value	Rationale
`HTTP_TIMEOUT_SECONDS`	`300 seconds`	Provides sufficient response time for large data transfers or external system processing.
`MAX_RETRIES_ON_ERROR`	`3 times`	Addresses transient network fluctuations or temporary external system unavailability, improving data transmission success rates.
`REQUEST_BODY_MAX_SIZE_MB`	`100 MB`	Accommodates request bodies that may contain large attachments like images or log files.
`AUTH_HEADER_NAME`	`Authorization`	Follows industry-standard authentication header naming for easier integration with external systems.
`API_KEY_TTL_HOURS`	`24 hours`	Balances security and usability by refreshing API keys periodically.
`LOG_LEVEL`	`INFO`	Records critical operations and errors in a production environment for easier issue tracing.

Three Common Mistakes

HTTP requests return a 400 Bad Request error, indicating incorrect data format. This happens when the sent JSON or XML structure does not match the external system's expectations, or when required fields, such as device serial numbers or timestamps, are missing.
Requests succeed, but the external system fails to process uploaded files correctly; file content appears garbled or unparseable. This is often due to an incorrect Content-Type header setting. For example, declaring application/json when sending a binary file causes the external system to use the wrong parser.
Data transmission frequently experiences connection interruptions or timeouts, especially when transferring large surgical logs or image data. This can occur if HTTP_TIMEOUT_SECONDS is set too low, failing to account for network latency or the external system's processing time for large files, or if network bandwidth is insufficient.

How to Verify Configuration

Send test data to the configured HTTP interface using a simulation tool (e.g., Postman). Observe if the returned status code is 200 OK and check if the response body content meets expectations.
On the external system's data receiving end, verify the received data entries, field values, and file content to confirm data integrity and accuracy, especially for critical information like surgical times and device parameters.
Check FastGPT's system logs or HTTP request logs to confirm no HTTP_TIMEOUT_SECONDS-related timeout errors occurred and that the retry mechanism triggered and succeeded when necessary.
Attempt to transfer data packets of varying sizes and types, including normal-sized sensor data and larger log files, to validate the robustness of REQUEST_BODY_MAX_SIZE_MB and HTTP_TIMEOUT_SECONDS configurations.
