摘要: 在載人航天飛行試驗任務中,地面指揮人員和醫(yī)學專家需及時掌握航天員在艙內(nèi)的生理狀況以保障航天員的安全。航天員的心率和呼吸率是評估航天員健康狀態(tài)的重要生理指標。如何快速、準確地計算航天員心率和呼吸率是工程任務面臨的技術(shù)難題之一。綜合考慮國產(chǎn)自主安全軟硬件條件下的計算能力,提出了基于自學習閾值的心率計算R波檢測算法,以及呼吸率計算的零點檢測算法,設(shè)計了一套心率和呼吸率可視化顯示軟件,提高了航天員生理數(shù)據(jù)處理的實時性和準確率,能夠為指揮人員和專家提供直觀可靠的決策依據(jù)。數(shù)據(jù)計算分析說明,所采用算法具備較高的準確率和較低的計算需求,能夠滿足待發(fā)段、上升段對航天員實施醫(yī)學保障與醫(yī)學監(jiān)督的需要。

Abstract: In the manned space flight mission, the ground commanders and medical experts shall timely grasp the physiological conditions of astronauts in the cabin to ensure the safety of them. The heart rate and respiratory rate of astronauts are important physiological indexes to evaluate the health status of astronauts. How to calculate the heart rate and respiratory rate of astronauts quickly and accurately is one of the difficult problems faced by engineering tasks. Comprehensively considering the computing power under the condition of domestic autonomous controllable software and hardware, this paper presents a heart rate calculation R-wave detection algorithm based on self-learning threshold, and the zero-detection algorithm of respiratory rate calculation, and also designs a set of visual display software of heart rate and respiratory rate. It improves the real-time and accuracy of astronauts′ physiological data processing, and provides intuitive and reliable decision-making basis for the commanders and experts. The calculation and analysis of data shows that the algorithm has high accuracy and low computational requirements. It can meet the needs of medical support and medical supervision for astronauts in the waiting and ascending stages.

我國載人航天事業(yè)飛速發(fā)展,自載人航天工程第五艘飛船神舟五號成功將首位航天員送入太空以來,截至2022年1月已有13位中國航天員先后乘坐神舟系列飛船進入太空。
在載人航天飛行試驗任務的執(zhí)行過程中,地面指揮人員和專家根據(jù)航天員相關(guān)生理參數(shù),準確指導并協(xié)助航天員及時控制航天員系統(tǒng)狀態(tài),是確保航天員生命安全與任務成敗的關(guān)鍵環(huán)節(jié)。
在飛船發(fā)射待發(fā)段和上升段,航天員的心電、呼吸等參數(shù)通過遙測通道實時下傳地面指揮系統(tǒng),地面系統(tǒng)通過建立數(shù)據(jù)模型等方法處理航天員生理參數(shù),以實時準確地獲得航天員的身體狀況,從而確保航天員的生命安全。因此,建立滿足實時性和精度要求的航天員生理遙測數(shù)據(jù)處理算法,是載人航天工程必須解決的技術(shù)難題。處理航天員心率和呼吸數(shù)據(jù),實時獲得航天員心電波形和呼吸波形,就是典型代表。
