AI Technical Summary

Technical Problem

Existing hyperbaric oxygen chambers cannot guarantee stress balance and structural safety during decompression. Traditional decompression control lacks a closed-loop adjustment mechanism, which increases the risk of damage to the chamber structure.

Method used

By collecting real-time data on valve opening changes and gas discharge flow rate, a decompression operation data sequence is constructed, the controllable adjustment range is identified, and the structural constraint control range is determined by combining the stress state of the cabin structure. The valve control parameters are then updated in real time to achieve dynamic closed-loop control.

Benefits of technology

It achieves high precision, safety, and controllability in the decompression process of the hyperbaric oxygen chamber, significantly improving the reliability of decompression operation and structural safety.

Abstract

The present application relates to the technical field of high-pressure oxygen cabin decompression, and particularly relates to a high-pressure oxygen cabin decompression safety control system and method based on big data. The method comprises the following steps: when the high-pressure oxygen cabin enters a decompression operation phase, collecting valve opening degree change data in the decompression process, synchronously collecting gas discharge flow data, and constructing a decompression operation data sequence; based on the decompression operation data sequence, identifying a controllable adjustment interval of the valve opening degree change data and the gas discharge flow data, and determining a structural constraint control interval of the gas discharge flow change; according to the structural constraint control interval, limiting the valve opening degree change amplitude, calculating the cabin pressure change rate, and determining a segmented pressure change path of the high-pressure oxygen cabin; the present application improves the reliability and structural safety guarantee level of the high-pressure oxygen cabin decompression operation by decompressing the high-pressure oxygen cabin.
