Objective: To develop a software system that can gather, manage and transmit signals of electrocardiograms, respiration, body temperature and blood pressure at real time, in order to monitor physiological signals of astronauts.
Method: Based on single-chip microprocessor, software system completed the A/D conversion, real-time signal processing, storage and transmission.
Result: The software system realized data acquisition of electrocardiogram, respiration, body temperature and blood pressure, as well as heart rate extraction from electrocardiogram, storage of physiological data, and transmission of physiological parameters to spacecraft.
Conclusion: The software system could meet the needs of medical monitoring during manned spaceflight.
